Frequently Asked Questions - DEVICENET SAFETY OMRON

How to install the DST1 safety terminal?

Fix the terminal on a DIN rail (35 mm) in an IP54 minimum enclosure. Use the end plates (PFP-M) to secure it. Leave 50 mm space above and below for ventilation.

What types of cables to use for connection?

Use solid wires of 0.2 to 2.5 mm² (AWG 24 to 12) or flexible wires of 0.34 to 1.5 mm² (AWG 22 to 16) with ferrules conforming to DIN 46228-4. The DeviceNet communication cable must be shielded.

How to configure safety parameters?

Use the Network Configurator software (version 2.0 or later for DST1-XD0808SL-1). Connect via the DeviceNet network, then set general parameters, safety input/output, test output, and delays. Lock the configuration with a password.

What to do in case of an error on a safety input or output?

Check the LEDs on the front panel (MS, NS, I/O indicators) and the error history via the Network Configurator. Possible causes include: external wiring fault, short-circuit, overcurrent, discrepancy between two channels. Remove the cause, then wait for the error memory time (configurable) before resetting.

How to reset after an error?

Ensure the error cause is eliminated and the memory time has elapsed. For inputs, the input must return to the inactive state (e.g., release emergency stop). For outputs, the command signals must return to inactive. An automatic or manual reset (via reset input) can be configured.

Can I use standard outputs in addition to safety outputs?

Yes, the test outputs (T0 to T3) can be configured as standard output (monitor) or sensor power supply. The DST1-XD0808SL-1 also allows additional outputs (same value, inverse, RUN indicator, etc.).

How to replace relays on the DST1-MRD08SL-1?

Cut off power. Disconnect the connectors. Remove the front cover and unclip the faulty relay. Insert a new relay of the same reference (OMRON). Replacement must be performed every 6 months maximum to maintain safety category 4.

What is the contact lifespan?

The relay contacts (DST1-MRD08SL-1) have a mechanical lifespan of about 5 million operations and an electrical lifespan of 100,000 operations at full load. Use the built-in operation counter to monitor wear and plan maintenance.

How to check the LED indicator status?

The MS (Module Status) and NS (Network Status) LEDs indicate the module and network status respectively. The I/O LEDs (IN/OUT) are on when the input/output is active. If an LED flashes or is red, refer to the troubleshooting table in the manual.

How to protect the configuration with a password?

In the Network Configurator, after downloading and verifying the configuration, enable configuration lock (Configuration Lock). Set a password. Any subsequent modification attempt will require this password.

Also, the status of the safety I/O data can be monitored in a standard PLC in an existing DeviceNet network using standard I/O communications or explicit message communications.

The DST1-XD0808SL-1 Logic Terminal has built-in logic functions. This enables direct control of local outputs from local inputs, allowing reaction time to be shortened.

1-4 Description of Safety Functions

1-4-1 DST1-series Safety I/O Terminals

Safe State

The following status is treated as the safe state by the DST1-series Safety I/O Terminals.

• Safety outputs: OFF
• Output data to network: OFF

graph TD
    A["DeviceNet"] --> B["Safe state"]
    B --> C["Outputs: OFF"]
    B --> D["Inputs"]
    E["Outputs to network: OFF"] --> B

Therefore, the DST1-series Safety I/O Terminals must be used for applications in which it enters into safe state when the safety outputs turn OFF and the output data to the network turns OFF.

Self-diagnosis Functions

Self-diagnosis is performed when the power is turned ON and periodically during operation. If an error occurs, it will be treated as a fatal error (the MS indicator will light in red), and the safety outputs and output data to the network will turn OFF.

Access Control by Password

After configuration data had been downloaded and verified, the configuration data within the DST1-series Safety I/O Terminals can be protected by a password.

    D --> E["Configuration data"]

Note Refer to the System Configuration Manual (Cat. No. Z905) for password setting.

1-4-2 Safety Inputs

Safety Inputs with Test Pulses (Input Circuit Diagnosis)

A test output is used in combination with a safety input. Specify the corresponding test output terminal to use as the test source. The test output terminal is used as a power supply to connect an external input device to the safety input terminal.

Example: DST1-ID12S-1

Here, IN0 and T0 are used in combination,

V V 0 1 2 3 4 5 6 7 G G T0 T1 T0 T1 T0 T1 T0 T1 24 V DC output with test pulse Safety input terminal External contact 24 V

A test pulse is output from the test output terminal to diagnose the internal circuit when the external input contact turns ON. Using this function, short-circuits between input signal lines and the power supply (positive side), and short-circuits between input signal lines can be detected.

24 V V G T0 24 V 0 V External contact IN0 Short-circuit between input signal line and power supply (positive side) T1 External contact IN1 Short-circuit between input signal lines

If an error is detected, safety input data and individual safety input status will turn OFF.

Setting Dual Channel Mode and Discrepancy Time

The consistency between signals on two channels can be evaluated. Either of the following settings can be selected. This function monitors the time during which there is a discrepancy in the logic between the two channels set as dual channels. If the length of the discrepancy exceeds the set discrepancy time (0 to 65,530 ms, in increments of 10 ms), the safety input data and the individual safety input status will turn OFF for both inputs.

IMPORTANT The dual channel function is used with 2 consecutive inputs that start from even input numbers: inputs 0 and 1, inputs 2 and 3, inputs 4 and 5, etc.

The following table shows the relation between terminal input and remote I/O data.

Dual channel mode	Input terminals		Remote I/O data		Meaning of data
	IN0	IN1	Safety input 0	Safety input 1
Dual Channel Equivalent	0	0	0	0	OFF
	0	1	0	0	OFF
	1	0	0	0	OFF
	1	1	1	1	ON
Dual Channel Complementary	0	0	0	1	OFF
	0	1	0	1	OFF
	1	0	1	0	ON
	1	1	0	1	OFF

Dual Channels, Equivalent

The status is treated as normal when both channels are ON or OFF. If one channel is ON and the other channel is OFF, it will be treated as an error, and the safety input data and the individual safety input status will turn OFF for both inputs.

Dual Channels, Complementary

The status is treated as normal when one channel is ON and the other channel is OFF. When both channels are ON or both channels are OFF, it is treated as an error, and the safety input data and the individual safety input status will turn OFF for both inputs.

Error Recovery

All conditions below are necessary to recover from an error that has occurred in a safety input.

• The cause of the error must be removed.
• The error latch time must have passed.
• The input signal must return to an inactive state and there must be no error condition detected. (e.g., by pressing the emergency stop switch or opening a door)

Input Delays

ON Delay

An input signal is treated as being OFF during the ON delay setting time (0 to 126 ms, in increments of 6 ms) after the input contact's rising edge. The input will turn ON only if the input contact remains ON after the ON delay time has elapsed. This helps prevent chattering of the input contacts.

IN OFF Remote I/O data Safety input ON OFF ON delay

OFF Delay

An input signal is treated as being ON during the OFF delay setting time (0 to 126 ms, in increments of 6 ms) after the input contact's falling edge. The input will turn OFF only if the input contact remains OFF after the OFF delay time has elapsed. This helps prevent chattering of the input contacts.

IN ON OFF Remote I/O data Safety input ON OFF OFF delay

1-4-3 Safety Outputs

Safety Outputs with Test Pulses (Output Circuit Diagnosis)

When the output is ON, the test pulse is turned OFF for 470 s in a cycle of 648 ms. Using this function, short-circuits between output signal lines and the power supply (positive side) and short-circuits between output signal lines can be detected.

If an error is detected, the safety output data and the individual safety output status will turn OFF.

IMPORTANT To prevent the test pulse from causing the connected device to malfunction, pay careful attention to the input response time of the device.

OUT ON OFF 580 µs 648 ms

Dual Channel Setting

When both channels are normal, the outputs can be turned ON.

The status is treated as normal when both channels are normal. If an error is detected for one channel, the safety output data and the individual safety output status will turn OFF for both channels.

Error Recovery

All conditions below are necessary to recover from an error that has occurred in a

safety output.

• The cause of the error must be removed.
• Error latch time must have passed.
• The output signals to the output I/O tags from the user application that correspond to the safety output must go inactive.

1-4-4 I/O Status Data

In addition to I/O data, the DST1-series Safety I/O Terminals support status data to check the I/O circuits. The status data includes the following data, for which remote I/O communications can be performed.

• Normal Flags (ON when there is no faults in the internal circuit and the external wiring)
• An AND Flag of the Normal Flags
• Output monitors (the actual output ON/OFF status)

Normal Flags

Normal Flags indicates whether each safety input, safety output, or test output is normal (normal status: ON, error status: OFF).

Output Monitors

The outputs monitors indicated the actual ON/OFF status of the safety outputs.

1-5 Logic Functions

The DST1-XD0808SL-1 supports logic functions.

1-5-1 Overview

Safety logic control can be easily performed by setting a combination of I/O data from local I/O terminals and remote I/O data from a Standard Master or Safety Master with the logic operations supported by the DST1-XD0808SL-1. In addition, the safety status can be monitored from standard controls by using the safety output terminals as additional outputs and outputting data such as error information.

IMPORTANT

• I/O connectors are detachable. Tighten the screws on the I/O connector to 0.25 to 0.3 N·m.
• Separate I/O signal cables from high-voltage lines and power lines.
• I/O signal cables must be no longer than 30 m.
• Do not apply power to safety output terminals or test output terminals. Doing so may cause burning or other damage to the product.
• Do not remove the label from the DST1 before wiring.
• Always remove the label after completing wiring to ensure proper heat dispersion.

2-4 Connecting the Communications Connector

Colored stickers are provided on the communications connector that match the colors of the lines to be inserted. Check that the colors of the lines and stickers match when wiring the connectors. The colors are as follows:

Color	Signal
Red	Power cable positive side (V+)
White	High side of communications data (CAN_H)
-	Shield
Blue	Low side of communications data (CAN_L)
Black	Power cable negative side (V-)

Refer to the DeviceNet Operation Manual (Cat. No. W267) for details on communications specifications and wiring.

IMPORTANT

• When connecting the communications connector to the DST1, tighten the screws on the communications connector to 0.25 to 0.3 N·m.
• OMRON's S8□□Power Supplies are recommended for communications power.

Note

- The internal power for the DST1-series Safety I/O Terminals is supplied from the communications power supply (V+, V−).

2-5 Node Address

Set the node address using the two rotary switches on the front panel of the DST1-series Safety I/O Terminals. The default setting is 63. Set the tens digit of the node address (decimal) using the left rotary switch and set the ones digit using the right rotary switch. A value between 00 and 63 can be set.

3 5 6 2 1 0 8 One digit of node address Tens digit of node address

If a node address between 64 and 99 is set, the node address can be set from the Network Configurator.

IMPORTANT

• The node address must be set while the communications power supply is turned OFF.
• Do not change the rotary switches while the power is ON. The DST1-series Safety I/O Terminals will detect this as a change in the configuration and will switch to fault state.
• Use a small flat-blade screwdriver to set the rotary switches, being careful not to scratch them.

2-6 Configuration

Configure the DST1-series Safety I/O Terminals using the Network Configurator. Refer to Section 3 Configuration for details on settings. Refer to the System Configuration Manual (Cat. No. Z905) for Network Configurator operating procedures.

3-2-5 Changing Default Standard I/O Assembly Data (DST1-XD0808SL-1 Only)

With the DST1-XD0808SL-1, a Network Configurator can be used to change the default standard I/O assembly data (Default Connection Path). This function is enabled for communications with a Standard Master which cannot change I/O assembly data. This kind of Standard Master can perform standard I/O communications with a Standard Slave using default I/O assembly data only. This function must be used to perform I/O communications using other I/O assembly data.

CS/CJ-series DeviceNet Unit

A CS/CJ-series DeviceNet Unit can change I/O assembly data, so there is no need to use this function to change the default standard I/O assembly data. Even if this function is used to change the data, the CS/CJ-series DeviceNet Unit settings will be given priority.

Note For details on making these settings, refer to the CS/CJ-series DeviceNet Unit Operation Manual (Cat. No. W380).

Using a Standard Master That Cannot Actively Change the Default Standard I/O Assembly Data

Set the initial standard I/O assembly data (Default Connection Path) when using the Network Configurator to set the configuration.

1,2,3... 1. Open the Edit Device Parameters Window of the DST1-XD0808SL-1. From Default Connection Path, select the I/O assembly data for the type of connection (Poll, BitStrobe, COS, Cyclic) to be used for I/O communications with the Standard Master. "Null" means that I/O assembly data is not to be used, i.e., that the data size is 0 bytes.

Edit Device Parameters Parameters Check that extended display is set. Parameter Name Value + Safety Input Logic 0 + Safety Input Logic 1 + Safety Input Logic 2 + Safety Input Logic 3 + Safety Input Logic 4 Make selections for the input connection and output connection to be used. + Safety Input Logic 5 - Default Connection Path 0469 Poll Default Input Connection Safety Input Assembly 3 0470 Poll Default Output Connection Null 0471 Bit-Strobe Default Input Connection Safety Input Assembly 3 0472 COS/Cyclic Default Input Connection Null 0473 COS/Cyclic Default Output Connection Safety Input Assembly 1 Safety Input Assembly 2 0471 Bit-Strobe Default Input Connection Safety Input Assembly 3 Default : Safety Input Assembly 3 [I/O size]Null : 0byte, Safety Input Assembly 1 : 1byte, Safety Input Assembly 2 : 2byte, Safety Input Assembly 3 : 7byte, Default Setup Copy Group... Expand All Collapse All OK Cancel

1. Download the specified configuration to the DST1-XD0808SL-1.
2. Set the Standard Master so that the connection type (Poll, BitStrobe, COS, or Cyclic) and I/O data size agree with the settings that were made in step 1 above.

Note “Null” means that I/O assembly data is not used, i.e., that the data size is 0 bytes. The output connection size for a Bit-Strobe connection is always 0 bytes.

! WARNING

For the DST1-MRD08SL-1, isolating transformers, such as TR1, that are used to isolate between overvoltage categories III and II must conform to IEC60742, and the insulation between the primary input and secondary output must satisfy at least the basic insulation standards of overvoltage category III.

One side of the secondary output of the isolating transformer must be grounded to prevent electrical shock in case of short-circuiting to the ground or to the frame of the isolating transformer.

To protect the isolating transformer and to prevent electrical shock in case of short-circuiting to the frame, insert fuses according to transformer specifications, i.e. at points F1, F2, and F3.

400 V AC/230 V AC L1 L2 L3 F1 TR1 F2 F6 F7 F8 MA MB Load III Overvoltage category II DST1-MRD08SL-1 F4 F5 MB MA F3 F1 to F8: Fuses MA and MB: Electromagnetic switches TR1: Isolating transformer

For Model DST1-MRD08SL-1, Insert a fuse rated at 3.15 A or less for each output terminal to protect safety output contacts from welding.

Confirm the fuse selection with the fuse manufacturer to ensure the dependability of the characteristics of the connected load.

IMPORTANT

• Supply power to both V0 and V1. The states of the relay contacts are internally monitored from the power supply of V 0.
• Power supply terminal V1 for the outputs is internally monitored. Supply the voltage in the specified range (20.4 to 26.4 VDC). If the voltage is supplied outside this range, voltage will not be supplied to the output circuits.

6-1 Reaction Time

6-1-1 Reaction Time Concept

The reaction time is the maximum time required for stopping an output, taking into account errors that may occur in safety chains (logical connections for creating safety devices, consisting of input devices, control devices including remote I/O devices, and output devices). The safety distance is found based on the reaction time.

6-1-2 Input Reaction Time

The input reaction time is the time from when an input terminal signal is changed until an output is sent to the network. The input reaction time is determined as follows:

Input reaction time = 16.2 ms + Input ON/OFF delay time

The input reaction time for the safety input logic result of the DST1-XD0808SL-1 is as follows:

Input reaction time = 22.2 ms + Input ON/OFF delay time

Note For details on reaction times for the entire system, refer to the DeviceNet Safety System Configuration Manual (Cat. No. Z905).

6-1-3 Output Reaction Time

The output reaction time is the time from when a network signal is received until the output terminal is changed. The output reaction time is determined as follows:

Output reaction time (DST1-MD16SL-1) = 6.2 ms

Output reaction time (DST1-MRD08SL-1) = 26.2 ms

Output reaction time (DST1-XD0808SL-1) = 6.2 ms + Output ON/OFF delay time

Note For details on reaction times for the entire system, refer to the DeviceNet Safety System Configuration Manual (Cat. No. Z905).

6-1-4 Local Input and Local Output Reaction Times

The DST1-XD0808SL-1 can stop local outputs according to local input status by using logic operations. In such cases, the Unit can independently calculate the reaction time.

7-2 Troubleshooting

I/O errors can be read out from safety input status, test output status, and safety output status.

Status data when I/O is normal: ON (1)

Status data when an error occurs I/O: OFF (0)

The details of errors can be read out by using explicit messages and the Network Configurator.

Note For I/O error latch time settings, the OFF status is maintained for at least the error latch time (0 to 65,530 ms, in increments of 10 ms) when individual safety input status turns OFF.

7-4 Maintenance

This section describes the routine cleaning and inspection recommended as regular maintenance. Handling methods when replacing the DST1-series Safety I/O Terminals are also explained here.

7-4-1 Cleaning

Clean the DST1-series Safety I/O Terminals regularly as described below to keep the network in optimal operating condition.

• Wipe the DST1-series Safety I/O Terminals with a dry, soft cloth for regular cleaning.
• When dust or dirt cannot be removed with a dry cloth, dampen the cloth with a neutral cleanser (2%), wring out the cloth, and wipe the DST1-series Safety I/O Terminals.
• Smudges may remain on the DST1-series Safety I/O Terminals from gum, vinyl, or tape that was left on for a long time. Remove these smudges when cleaning.

Note

Never use volatile solvents, such as paint thinner or benzene, or chemical wipes to clean the DST1-series Safety I/O Terminals. These substances may damage the surface of the DST1-series Safety I/O Terminals.

7-4-2 Inspection

Inspect the system periodically to keep it in optimal operating condition.

In general, inspect the system once every 6 to 12 months, but inspect more frequently if the system is used in high-temperature, humid, or dusty conditions.

Inspection Equipment

Prepare the following equipment before inspecting the system.

Equipment Required for Regular Inspection

Phillips screwdriver

A flat-blade screwdriver

A screwdriver for connecting communications connectors

A tester (or a digital voltmeter)

IMPORTANT

• The maintenance interval for the relay contacts must not exceed a period of 6 month to meet safety category 4 in accordance with EN 954-1.
• The G7SA-2A2B must be used when replacing safety relays.

7-4-3 Replacing the DST1

The network consists of the DeviceNet Unit (master) and DST1 Terminals. The entire network is affected when a DST1 is faulty, so a faulty DST1 must be repaired or replaced quickly. We recommend having spare DST1 Terminals available to restore network operation as quickly as possible.

Precautions for Replacing the DST1

Observe the following precautions when replacing a faulty DST1.

After replacement, make sure that there are no errors in the new DST1.

When a DST1 is being returned for repair, attach a detailed description of the problem and return the DST1 to your OMRON representative.

If there is a faulty contact, try wiping the contact with a clean, lint-free cloth dampened with alcohol.

Settings after Replacing a DST1

After replacing a DST1, set the new DST1's switches and configuration data to the same settings that were used on the old DST1.

WARNING

Safety functions may be impaired and serious injury may occasionally occur. When replacing a device, configure the replacement device suitably and confirm that it operate correctly.

Appendix

Appendix 1: DeviceNet Explicit Messages

DeviceNet explicit messages sent from the Master Unit to the DST1-series Terminals can be used to read or write any parameter of a specified Terminal. The DST1-series Terminal processes a command sent from the Master Unit and then returns a response.

A-1-1 Basic Format of Explicit Messages

The basic format of each command and response is shown below.

Command Block

Destination node address

Service code

Class ID

Instance ID

Attribute ID

Data

Destination Node Address

The node address of the Unit that is sending the explicit message is specified with on hexadecimal byte.

Service Code, Class ID, Instance ID, and Attribute ID

The parameters used for specifying the command, processing object, and processing content.

Note The number of bytes designated for the class ID, instance ID, and attribute ID depend on the Master Unit. When sent from an OMRON DeviceNet Master, the class ID and instance ID are 2 bytes (4 digits) each, and the attribute ID is 1 byte (2 digits).

Data

Data is not required when a read command is used.

Response Block

Normal Response Block

Number of bytes received

Source node address

Service code

Data

Error Response Block

Number of bytes received0004 hex (fixed)

Source nodeaddress

Service code

Error code

Number of Bytes Received

The number of bytes received from the source node address is returned in hexadecimal. When an error response is returned for an explicit message, the number of bytes is always 0004 hex.

Source Node Address

The node address of the node from which the command was sent is returned in hexadecimal.

Service Code

For normal completions, the service code specified in the command with the leftmost bit turned ON is stored as shown in the following table.

Function	Command service code	Response service code
Read data	10 hex	90 hex
Write data	0E hex	8E hex
Reset	05 hex	85 hex
Save	16 hex	96 hex

When an error response is returned for an explicit message, the value is always 94 hex.

Data

Read data is included only when a read command is executed.

Error Code

The explicit message error code. For details, refer to the list of error codes in the following table.

Error Codes

Code	Error name	Cause
08FF	Service not supported	The service code is incorrect.
09FF	Invalid attribute value	The specified attribute value is not supported.The data written was outside the valid range.
16FF	Object does not exist	The specified Instance ID is not supported.
15FF	Too much data	The data is larger than the specified size.
13FF	Not enough data	The data is smaller than the specified size.
