Frequently Asked Questions - AC007A IFM

How to address the AC007A module?

Use the AC1144 addressing unit. You can address the module by direct contact or by infrared. The address must be between 1 and 31; at delivery, the address is 0. For infrared addressing, disable AS-i communication and power the module via the AS-i block.

What does the red LED continuously on mean?

The red LED on indicates an AS-i communication error. The slave is not participating in normal data exchange, for example if the address is 0 or the AS-i cable is disconnected.

What does the flashing red LED mean?

The red flashing indicates a peripheral fault, such as an overload or short circuit of the sensor supply. This fault is reported to the AS-i master via the status register.

What is the supply voltage of the module?

The module is powered via the AS-i cable with a voltage of 26.5 to 31.6 V DC. Consumption is less than 150 mA. For actuators, an external supply of 24 V DC (15...30 V) according to TBTP is required.

How many sensors and actuators can I connect?

The module allows connection of 2 sensors (2-wire or PNP 3-wire) and 2 actuators (15...30 V DC). Connections are made via M12 sockets.

How to perform infrared addressing?

First disable AS-i communication (for example by disconnecting the master on ifm power supply blocks). Power the module with the AS-i block, then use the AC1144 addressing unit with the E70211 cable to transmit the address via infrared.

What is the maximum current per output?

The nominal current per output is 1 A in DC13 operation, with a maximum of 2 A per module. For solenoid valve control, power is designed up to 20 W (according to IEC 947-5-2).

How do I know if the module is properly powered?

The green LED lights up when the AS-i supply voltage is OK. If it is off, check the power supply and the AS-i cable.

What types of sensors are compatible?

The module accepts 2-wire sensors or PNP 3-wire sensors. The inputs are powered by the module (L+ and L- on the M12 socket).

What to do in case of a peripheral fault?

The fault is indicated by the flashing red LED. Check the sensor connections to eliminate any overload or short circuit. The fault is also transmitted to the AS-i master (version 2.1) for diagnosis.

USER MANUAL AC007A IFM

Function and features

• The AS-i module operates as a slave in the AS-i network (AS-i profile: S-3.0.E). It connects two sensors (2-wire sensors or PNP 3-wire sensors) and two actuators (15 ... 30 V DC) with the AS-i master.
• AS-interface version 2.1
• Operating voltage 26.5 ... 31.6V
• Current consumption < 150mA
• Max. current load for all inputs total 100mA
• External power supply to PELV
  Voltage range 24V DC (15...30V DC)

• Max. current load per output (DC13)* 1A (typ.), max. 2A per module

• 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).

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 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.

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 reliable 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. 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.
