Frequently Asked Questions - AC008A IFM

How to address the AS-i module AC008A?

Use the addressing unit AC1144 (wired or infrared). The default address is 0. Assign a free address between 1 and 31. When using with the base AC5003, first address the module then mount it on the base.

What do the LEDs on the module indicate?

Yellow LED: outputs activated. Green LED: power OK. Red 2 LED on: AS-i communication error (e.g., address 0). Red 2 LED flashing: peripheral fault (overload or short-circuit of an output).

What power supply is required for this module?

The module is powered by the AS-i cable (26.5...31.6 V) and requires an external 24 V DC power supply (range 15...30 V DC) for the actuators. Current consumption is less than 50 mA.

How to perform infrared addressing?

Disable AS-i communication (yellow cable). Power the slaves via the AS-i power supply unit. Use the addressing unit AC1144 with the infrared cable E70211. With ifm AS-i SL modules, disconnect the master to disable communication.

What is the maximum output current per output?

The output current per output (category DC13) is 1 A typical, and 2 A total for the module.

How to detect overload or short-circuit?

The red 2 LED flashes in case of peripheral fault. The fault is signaled to the AS-i master via the internal 'peripheral fault' bit in the status register (version 2.1).

Can I use this module in explosive areas?

Yes, the module is designed for use in explosive areas. Strictly follow the usage instructions provided in the manual.

How many AS-i modules can be connected to one master?

The maximum number of modules per master is 31.

What AS-Interface version is supported?

The module supports version AS-Interface 2.1.

How to clean or maintain the module?

The manual does not provide specific cleaning instructions. Disconnect power before any intervention. Use a dry lint-free cloth for the exterior. Avoid solvents.

Function and features

The AS-i module operates as a slave in the AS-i network (AS-i profile: S-8.0.E). It connects four actuators (10 ... 30V DC) with the AS-i master.

• maximum number of modules per master: 31
• operating voltage 26.5 ... 31.6V
• external power supply to PELV
• current consumption <50mA
• voltage range 24V DC (15 ... 30V DC)
- max. current load per output (DC13)* 1A (typ.), 2A per module
- AS-interface version 2.1

* Utilisation category (DC13): The switch-on and switch-off capacity for the triggering of solenoids is rated up to 20W (to IEC 947-5-2).

Operating and display elements

Addressing

Assign a free address between 1 and 31. At the factory the address is set to 0.

Addressing with the adressing unit AC1144

If it is used with the FC-E lower part AC5003 the module must first be addressed via the addressing unit AC1144 and then mounted onto the lower part.

Infrared addressing

The AS-i module also offers the option of infrared addressing with the addressing unit AC1144.

The AS-i communication (yellow cable) must be switched off during the infrared addressing.

Supply the slaves with voltage via the AS-i power supply. Addressing is carried out via the IR addressing cable E70211.

When the ifm AS-i power supplies type SL are used the communication can be deactivated via a plug on the power supply. To do so, disconnect the master.

Operation

Check the safe functioning of the unit. Display by LEDs:

• LED 1 yellow: output switched
• LED green: voltage supply o.k.
- LED 2 red is lit: AS-i communication error, slave does not participate in the “normal” data exchange, e. g. slave address 0
- LED 2 red flashing: peripheral fault, e.g. overload or short circuit of the output

Overload and short circuit of the output are signalled to the AS-i master (version 2.1) via the "peripheral fault" flag in the status register.
