Applicable Terminal: DST1-XD0808SL-1 3-2-5 Changing Default Standard 1/0 Assembly Data (DST1-XD0808SL-1 Only) With the DST1-XD0808SL-1, a Network Configurator can be used to change the default standard 1/0 assembly data (Default Connection Path). This func- tion is enabled for communications with a Standard Master which cannot change 1/0 assembly data. This kind of Standard Master can perform stan- dard 1/0 communications with a Standard Slave using default 1/0 assembly data only. This function must be used to perform 1/0 communications using other 1/0 assembly data.

CS/CJ-series DeviceNet Unit Note A CS/Cy-series DeviceNet Unit can change 1/0 assembly data, so there is no need to use this function to change the default standard 1/0 assembly data. Even if this function is used to change the data, the CS/CJ-series DeviceNet Unit settings will be given priority. For details on making these settings, refer to the CS/Cy-series DeviceNet Unit Operation Manual (Cat. No. W380). Using a Standard Master That Cannot Actively Change the Default Standard 1/0 Assembly Data 1,2,3.. Parameters | E|18 «= Check that extended display is set. Parameter Name Set the initial standard 1/0 assembly data (Default Connection Path) when using the Network Configurator to set the configuration.

8. Setthe Standard Master so that the connection type (Poll, BitStrobe, COS,

or Cyclic) and 1/0 data size agree with the settings that were made in step 1 above. “Nul!” means that 1/0 assembly data is not used, i.e., that the data size is O bytes. The output connection size for a Bit-Strobe connection is always O0 bytes.

Reaction Time Section 6-1 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 1/0 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-MRDO8SL-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 independenily calculate the reaction time.

Maintenance Section 7-4 7-4 Maintenance This section describes the routine cleaning and inspection recommended as regular maintenance. Handling methods when replacing the DST1-series Safety 1/0 Terminals are also explained here. 7-4-1 Cleaning Clean the DST1-series Safety 1/0 Terminals regularly as described below to keep the network in optimal operating condition. + Wipe the DST1-series Safety 1/0 Terminals with a dry, soft cloth for regu- lar 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 1/0 Terminals. + Smudges may remain on the DST1-series Safety 1/0 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 1/0 Terminals. These substances may damage the surface of the DST1-series Safety 1/0 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 frequenily if the system is used in high-temperature, humid, or dusty condi- tions. 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) Industrial alcohol and a clean cloth Other Equipment That May Be Required A synchroscope An oscilloscope A thermometer or hygrometer

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 DSTI is faulty, so a faulty DST1 must be repaired or replaced quickly. We recommend having spare DST1 Termi- nals 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 DST 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 DSTI 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 con- firm that it operate correctly.

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 |Service |Class Instance |Attribute |Data address code ID ID ID 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 |Service code |Data address Error Response Block Number of bytes received | Source node | Service code | Error code 0004 hex (fixed) address 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.
