Frequently Asked Questions - AC1308 IFM

How to configure the address of an AS-i slave?

Use the Addressing menu on the controller. You can re-address a connected slave or enable automatic addressing (easy startup) to assign the next available address.

What is the difference between project mode and protected mode?

Project mode allows configuration of the AS-i system without configuration monitoring. Protected mode is normal operation where the master monitors the configuration and reports errors.

What do the LEDs on the controller indicate?

The PWR/COM LED indicates the presence of AS-i power and detection of slaves. PROJ indicates project mode. CONF/PF signals a configuration difference or peripheral fault. The DeviceNet LEDs indicate network and module status.

How to adjust the screen contrast?

Press simultaneously the right button and the + button (increase) or - button (decrease) to adjust the contrast.

What power supply to use for the controller?

The controller requires a 24 V DC (20...30 V DC) power supply. For cULus certification, use a certified class 2 power supply, for example DN2112 or DN2011 from ifm.

How to connect the DeviceNet interface?

Connect the pins: 1: V-, 2: CAN_L, 3: Shield, 4: CAN_H, 5: V+. Configure the baud rate (125k, 250k or 500k bit/s) and the DeviceNet slave address in the menu.

What is the maximum distance for the RS232C interface?

The maximum distance between the controller and the host is 20 meters. Use the programming cable E70320.

How to update the controller firmware?

Use a specific programming software and connect via the RS232C interface. The Firmware Update option is found in the main menu.

What to do in case of configuration error (CONF/PF LED lit)?

The preselected configuration does not match the actual configuration. Check the connected slaves and their addresses. Use Config all to read the current configuration and update it.

How to navigate in the controller menu?

Use the left (MENU), up, down buttons to navigate. Press buttons simultaneously to change the menu language (German/English).

DeviceNet Status LEDs (Network Status)

Function and features

• The controller _e (AC1308/AC1314) integrates one or two AS-i masters (both in accordance with the AS-i version 2.1), a mini controller and a DeviceNet interface
• It controls the exchange of data to the sensor /actuator level
• processes the peripheral data in the integrated processor (signal preprocessing)
• works as stand-alone controller with exchange of data to the PC (visualisation)
• communicates with the higher control level (in the gateway mode)

Programming interface RS232C

• Baud rate 4800 to 115,200 baud
- Max. distance between controller e and host: 20m
- Potential separation from the controller e power supply
- Programming cable E70320 for connection to host required

DeviceNet interface

• Baud rate 125k, 250k and 500kbit/s
• Max. distance between controller _e and host: depending on the baud rate
• Potential separation from the controller _e power supply
• Up to 64 controllers connected in parallel
• Pin connection: Pin 1: V-; Pin 2: CAN_L; Pin 3: Shield; Pin 4: CAN_H; Pin 5: V+

Installation

Fix the controller _e onto a 35mm rail. The protection rating of the unit is IP20, therefore it should be mounted in a protected location (e.g. control cabinet).

Ensure a condensation-free environment. Avoid excessive dust, vibration and shock. The air circulation through the vents must not be impeded.

Avoid installation in direct vicinity of frequency converters.

Electrical connection

Disconnect the installation from power. Connect the unit as indicated on the terminals. Never connect the minus potentials to each other or the minus potentials to the FE connection. Ensure an electrically safe ground connection between AS-i controller _e (terminal FE) and ground of the unit.

Supply the DeviceNet controller _e with a 24V DC voltage (20...30V DC).

Connection is made to the terminals +24V and 0V.

The DeviceNet controller _e has the cULus approval when supplied by a certified class 2 source.

Examples of the power supplies available from ifm electronic gmbh:

Power supply DN2112 for applications that require the cULus approval.

Power supply DN2011 for applications that require no cULus approval.

Operating and indicating elements

Information concerning the state of the master (AC1308) / master AC1314) and the connected system is given via three diagnostic LEDs on the controller _e .

• LED PWR/COM lights: AS-i voltage present, at least one slave was detected
• LED PWR/COM flashes: AS-i voltage present, but no slave was detected correctly
• LED PROJ lights: Projection mode active, the configuration monitoring is deactivated
• LED PROJ flashes: Projection mode active, changeover to protected mode not possible as a slave with the address 0 is connected
• LED CONF/PF lights: Projected and current configuration do not match
• LED CONF/PF flashes: Periphery fault on at least one connected slave

DeviceNet status LEDs (Network Status)

• LEDs off: DeviceNet voltage not ok

• LED green lights: online, connected

- LEDs off: DeviceNet voltage not ok - LED green lights: online, connected

• LED green flashes: online, not connected
- LED red lights: BUS OFF
• LED red flashes: timeout error during data transmission

DeviceNet status LEDs (module status)

• LEDs off: no supply voltage
- LED green lights: controller e online
• LED red lights: unrecoverable system error
• LED red flashes: system error

Operation

To operate an AS-i system a special AS-i power supply is required. Connection is made to the terminals AS-i + and AS-i -.

The DeviceNet controller _e has the cULus approval when supplied by a certified class 2 source.

Examples of the power supplies available from ifm electronic gmbh: Power supply AC1216 for applications that require the cULus approval. Power supply AC1218 for applications that require no cULus approval.

Disconnect the power supply before connecting the controller _e .

The AS-i system is operated ungrounded. AS-i + and AS-i - are to be symmetrical to the ground potential of the installation. Ensure a low resistance connection of the symmetry point of the AS-i power supply (terminal shield) to the ground of the installation.
