Frequently Asked Questions - AC2509 IFM

How to address the AC2509 module?

Use the addressing unit AC1144 or infrared addressing. The address must be between 1 and 31 (factory: 0). For infrared addressing, disable AS-i communication by disconnecting the master.

What does the red FAULT LED permanently lit mean?

A fixed red LED indicates an AS-i communication error: the slave is not participating in the normal data exchange (e.g., slave address 0).

What does the red FAULT flashing LED mean?

A red flashing indicates a peripheral fault, e.g., faulty sensor supply, overload or short circuit of the output.

How to mount the module on the wiring base?

Mount the module on the wiring base connected to the AS-i network, respecting a tightening torque of 0.8 Nm.

What is the protection rating of the AC2509 module?

The module offers IP67 protection provided that unused sockets are covered with caps (ref. AC3004).

How to connect sensors and actuators?

Connection is made via M12 sockets. The pin assignment is: pin 1 = sensor supply L+, pin 3 = L-, pin 4 = switching output, pin 5 = functional ground.

How to perform infrared addressing?

Use the addressing unit AC1144 with the infrared cable E70211. Before addressing, disable AS-i communication by disconnecting the master and power the slaves via the AS-i power supply unit.

What is the maximum number of AS-i slaves per master?

The maximum number of modules (slaves) per master is 31.

How to check the correct operation of the module?

Observe the LEDs: a green LED lit indicates correct power supply; the yellow LEDs indicate the status of inputs/outputs; a red or flashing LED signals a fault.

Where to find the complete data sheet of the AC2509?

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: periphery fault, e.g. sensor supply / over load or short circuit of the output
• LED 3: infrared receiver

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