Frequently Asked Questions - AC2507 IFM

How to address the AS-i module AC2507?

Addressing can be done via the AC1144 addressing unit (wired or infrared). If the module is mounted on a base with an addressing plug (AC5011), use the E70213 cable. For infrared addressing, disconnect the AS-i master and use the E70211 cable.

What does the red LED lit on the module mean?

The red FAULT LED lit indicates an AS-i communication error: the slave is not participating in normal data exchange (for example address 0). If it flashes, it signals a peripheral fault such as an overload or short circuit on the power supply of a sensor or output.

What is the maximum number of AC2507 modules that can be connected to an AS-i master?

The AS-i profile S-3.0 allows up to 31 modules per master, as each module occupies a unique address from 1 to 31.

How to mount the AC2507 module on the base?

Mount the module on the wiring base connected to the AS-i network. Tighten the screw with a torque of 0.8 Nm to ensure good contact and sealing.

Which connectors to use for sensors and actuators?

Sensors/actuators connect to the M12 connectors of the module. The pins are: 1 (sensor supply L+), 3 (L-), 2+4 (data input), 5 (n.c.) for inputs; and for outputs: 4 (switching output +), 3 (external voltage -), 1,2,5 (n.c.). Cover unused connectors with AC3004 caps to maintain IP67.

How to address the module via infrared?

Disable AS-i communication by disconnecting the master, then power the slaves with the AS-i power supply. Use the AC1144 addressing unit with the infrared cable E70211. If using an ifm AS-i SL power supply, communication can be disabled via a dedicated connector.

What does the green PWR LED do?

The green PWR LED indicates that the module's power supply is correct. If it is off, check the voltage on the AS-i bus.

How to ensure IP67 protection of the module?

To ensure IP67, all unused M12 connectors must be capped with AC3004 protection caps. Additionally, the module must be properly mounted on the base with the recommended torque.

What are the functions of the yellow LEDs?

Each yellow LED corresponds to an input/output channel: it lights up when the input or output is switched (active). There are 4 yellow LEDs for the 4 M12 connectors.

What to do in case of a peripheral fault (flashing red LED)?

A peripheral fault (overload or short circuit) is signaled by a flashing red LED. Check the cables and connected sensors/actuators. The fault is also transmitted to the AS-i master via the 'peripheral fault' bit of the status register.

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 sensors /actuators to the M12 sockets. Cover the sockets not used with the protective caps (AC3004) 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

Do not remove the addressing plug while live.

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).

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: input/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. sensor supply output overloaded or shorted

• LED 3: infrared receiver

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.
