Operating and display elements

Mounting
Mount the module onto the wired module lower part of the AS-i network, tightening torque 0.8 Nm.
Technical data
You can download the data sheet from the Internet address www.ifm-electronic.com if required.
Electrical connection
Connect the sensors to the M12 sockets. The sensor supply via the AS-i network. Do not connect the inputs with an external potential.
Cover the sockets not used with the protective caps (AC73004) to guarantee protection rating IP67.

Addressing with the addressing unit AC1144
If the mounted and wired module is used with the FC lower part AC5010 (with addressing socket), it can be addressed via the addressing cable (E70213).

Do not remove the addressing plug while live.
If it is used with the FC lower part AC5000 (without addressing socket) 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. To do so, disconnect the master.
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 SL are used the communication can be deactivated via a plug on the power supply.
If a slave with the ID code "A" (option of extended addressing mode) is connected to a master of the first generation (version 2.0), the parameter P3 must be 1 and the output bit D3 = 0^* . The output bit D3 must not be used.
If a slave with the ID code "A" (option of extended addressing mode) is connected to a master of the first generation (version 2.0), an address between 1A and 31A must be assigned to this slave.
- default setting
Operation
Check the safe functioning of the unit. Display by LEDs:
- LED 1 yellow: input 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 sensor supply
- LED 3: infrared reciever
Overload and short circuit of the input supply are signalled to the AS-i master (version 2.1) via the "peripheral fault" flag in the status register.
