Frequently Asked Questions - AC1008 IFM

How to connect the power supply of the AC1008 controller?

Turn off the installation. Connect +24 V to the +24 V terminal and 0 V to the 0 V terminal. Never connect the negative potentials to each other or to ground. Ensure a good ground connection via the PE terminal.

How to configure the controller for gateway operation?

Configuration is done via explicit DeviceNet messages. Use mode 'd' to set the DeviceNet baud rate, and mode 'C' for data lengths. The factory setting (C1=16, C2=16, CC=00) corresponds to gateway mode. After modification, briefly turn the controller off and on or confirm address A to activate changes.

What does the flashing of the CTRL LED mean?

The CTRL LED indicates the controller status: it is on in RUN mode (program processing active) and off in STOP mode (processing stopped). Flashing may indicate an error; check the error messages on the display.

How to assign an address to an AS-i slave?

Use mode 5 to assign address 0 to a slave, or mode 6 to assign a new address to slave 0. First select the mode and master, then the SET button to confirm. Automatic addressing must be enabled (mode 7).

What to do in case of 'Addressing not possible' error?

This error appears if automatic addressing is not active, if slaves are missing, or if protected mode is not active. Check the setting of mode 7 (automatic addressing) and ensure all slaves are present. Activate protected mode if necessary.

How to set the transmission speed of the RS232 serial interface?

Select mode 'b' with MODE, then press SET to choose the speed: b_48 (4800 baud), b_96 (9600), b192 (19200 - default), b384 (38400), b576 (57600), b624 (62400). Confirm with SET.

How to update the configuration after parameter modification?

After modifying parameters (e.g., data lengths or baud rate), either turn the controller off and on, or confirm address A (mode A) so that the new values are applied.

What is the role of gateway mode?

Gateway mode allows the controller to communicate with a higher-level system (supervisor). AS-i data is transmitted via DeviceNet. The controller performs signal preprocessing and cyclic or change-of-state exchange.

How to interpret the error messages displayed on the controller?

The display shows error codes (e.g., E1, E2, etc.). Refer to the manual for the meaning: for example, 'F1' indicates a DeviceNet bus error, 'F3' a different software version between AS-i bundles. The list of faulty slaves can be accessed via mode 1.

How to reset the AC1008 controller to factory settings?

There is no direct factory reset function. To restore default settings, manually set the modes: address 063 (mode A), speed 19200 baud (mode b), data lengths C1=16, C2=16, CC=00 (mode C). Turn the controller off and on.

USER MANUAL AC1008 IFM

Functions and features

• The AS-i DeviceNet controller integrates 1 or 2 AS-i masters, a mini controller and a group 2 Only DeviceNet slave interface to ODVA specification (Open DeviceNet Vendor Association)
• it controls the data exchange to the sensor/actuator level
• it processes the peripheral data in the integrated processor (signal preprocessing)
• it works as stand-alone controller with data exchange to the PC (visualisation)
• it is monitored by a watchdog
• it communicates with the higher-level control system (in the gateway mode)
• it supports the following operating modes according to the specifications: Cyclic polling, Bit strobe, Change of state and Cycle.
  It is configured via explicit messages.

Mounting

Mount the controller onto a 35mm rail. The unit has protection IP20, therefore it should be mounted in a protected place (e.g. switching cabinet).

Electrical connection

Disconnect power. Connect the unit according to the terminal marking. Never connect the minus potentials to each other or the minus potentials and the PE connection.

Ensure an electrically safe ground connection between the AS-i controller (PE terminal) and the ground connection of the unit.

After application of the supply voltage all the LEDs and the LED display are switched on (LED test); then the version numbers of the hardware and the software are displayed for 1s each on the LED display.

Error messages

Display of missing/defective slaves

(digit 2 = master; digits 3 and 4 = slave no.); the slaves are displayed at intervals of seconds.

The list of failed slaves can be stored until the slaves have been replaced.

- Press the SET button twice (for the list of master 1) or SET -MODE - SET (for the list of master 2). The lowest address of the error list is displayed flashing.

- Replace the failed slave by a slave with the same configuration and with the address 0; it will receive the indicated address; (the function “automatic addressing” must be activated). If other addresses are displayed, proceed in the same way until the list has been completed.

- The function will be ended when the slaves have been replaced or the SET button has been pressed.
