Frequently Asked Questions - AC2558 IFM

How to address the AC2558 module?

You can address the module in several ways: via the addressing unit AC1144 with a cable (E70213) or by infrared with the E70211 cable. If you use the base FK-E AC5011 (with addressing connector), plug the cable directly. For the AC5003 base (without connector), address the module before mounting. Never remove the addressing connector while powered.

What does the red LED permanently on mean?

The red LED on indicates an AS-i communication error. The slave does not participate in normal data exchange, for example if the address is 0 (default). Check the address and AS-i wiring.

What does the flashing red LED mean?

A flashing red LED indicates a peripheral fault, such as an overload or short circuit on an output. This fault is transmitted to the AS-i master (version 2.1) via the internal 'peripheral fault' bit.

How to protect unused M12 connectors?

To ensure IP67 protection, cover unused connectors with the provided caps (reference AC73004).

What is the tightening torque for mounting the module?

The module must be tightened onto the wiring base with a torque of 0.8 Nm.

Can I use infrared addressing?

Yes, the AC2558 module supports infrared addressing via the AC1144 addressing unit and the E70211 infrared cable. The AS-i communication (yellow cable) must be deactivated during addressing.

How to deactivate AS-i communication for infrared addressing?

Disconnect the AS-i master or, if using an ifm AS-i SL power supply, use the designated connector on the power supply. The slave power supply must remain active.

What is the maximum number of AC2558 modules per master?

The maximum number of modules per AS-i master is 31.

What AS-i profiles are supported by the module?

The module uses the profile S-8.0.E (AS-interface version 2.1).

What to do if the module does not work after mounting?

Check the LEDs: if the green LED is off, power is missing. If the red LED is on, the address is probably 0 or there is a communication problem. Make sure the module is properly addressed (address between 1 and 31) and that the outputs are not overloaded or short-circuited.

Function and features

• AS-i profile: S-8.0.E
  • maximum number of modules per master: 31
• AS-interface version 2.1
• special features AC2558: stainless steel screws, Viton sealing

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 plugs of the actuators to the M12 sockets. Cover the sockets not used with the protective caps (AC73004) to guarantee protection rating IP67.

Addressing

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

Addressing with the addressing unit AC1144

If the mounted and wired module is used with the FC-E lower part AC5011 (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-E lower part AC5003 (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.

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.
