Frequently Asked Questions - AL2410 IFM

What are the indicator lights of the AL2410 module?

The module has two types of LEDs: a PWR/FLT LED (green = correct operation, red = short-circuit on a sensor supply, off = undervoltage or power off) and a yellow IN LED per input (on = HIGH signal, off = LOW signal).

How to connect sensors to the module?

Connect the sensors to the M8 sockets according to the pinout: pin 1 = sensor supply +, pin 3 = sensor supply -, pin 4 = data input. Tighten with a torque of 0.3 to 0.5 Nm. Cover unused sockets with protective caps to ensure the IP rating.

What is the required supply voltage?

The supply is via the IO-Link port with a voltage of 18 to 30 V DC. The total required current is 550 mA for the AL2410. Ensure that the IO-Link master provides sufficient current.

How to configure the module via IO-Link?

Configuration is done using the IO-Link master. The device cyclically transmits the input states, short-circuit information, and hardware identification. Specific parameter lists are available on the www.ifm.com website.

What to do in case of a short-circuit?

In case of a short-circuit on a sensor supply, the PWR/FLT LED turns red. The information is also transmitted via IO-Link (byte 2). Disconnect the power, locate the fault and correct it. The protection is combined per group of 4 inputs.

What is the maximum cable length?

The cable length between the module and the sensors must not exceed 30 meters to ensure correct operation.

How to mount the module correctly?

Mount the module on a flat surface using M4 screws and washers. The tightening torque is 1.2 to 1.5 Nm. Ensure the bottom of the module is in full contact with the surface. For side mounting, use two M4 screws with a maximum torque of 1 Nm.

How many discrete inputs does the AL2410 have?

The AL2410 module has 4 discrete inputs of type 2 according to IEC 61131-2. Each input can be connected to a sensor via an M8 socket.

What is the maximum current per sensor supply?

Each process connection provides a nominal current of 100 mA. The protection is grouped by 4: the total current per group is 400 mA, which can be drawn from a single output of the group.

Does the module require maintenance?

No, this module requires no maintenance. At end of life, dispose of it in accordance with local environmental regulations.

4 Function

4.1 Communication, parameter setting, evaluation

4.1.1 IO-Link data

The device

• transmits the current states of the digital inputs cyclically in byte 0. Byte 1 is not used and always transfers the value '0'.
• transmits the device information "short circuit" (SC) cyclically in byte 2.
• transmits the equipment identification cyclically in byte 3.
• provides the equipment identification for writing acyclically (index 688, sub-index 0).

• indicates the current state of an input (yellow LED).
• indicates a correct operation (green PWR/FLT LED lights).
• indicates a short circuit of one or several sensor supplies (red PWR/FLT LED lights).

4.1.3 Parameter setting

Device-specific parameter lists for IO-Link parameter setting are available

4.2 Digital inputs

Depending on the version the device has 4 (AL2410) or 8 (AL2411) digital inputs (type 2 input to IEC 61131-2). All inputs refer to the sensor supply potential.

4.3 Sensor supply

Depending on the version the device has 4 (AL2410) or 8 (AL2411) process connections on the front panel. Each process connection has a sensor supply rated for a nominal current of 100mA .

The short-circuit protection applies to a group of 4 inputs

• group 1: inputs X1.0...X1.3
• group 2: inputs X1.4 - X1.7 (only AL2411)

and is rated for 400mA per group.

So the total current of the group of 4 inputs can be taken from one of the process connections of the corresponding group.

Maximum cable length < 30 m .

A short circuit or overload has no effect on the sensor supply of the other group (only AL2411). Moreover every sensor supply has a short-circuit and overload

detection which is indicated by the red PWR/FLT LED and via the IO-Link interface.

A correct operation is indicated by the green PWR/FLT LED. The output voltage of the sensor supply is in linear proportion to the input voltage (positive supply cable of the IO-Link port). Voltage can vary within the IO-Link specification (18...30 V).

5 Installation

Disconnect power before installation.

For installation choose a flat mounting surface. The entire bottom of the module must lie flat on the mounting surface.

• Fasten the module onto the mounting surface using M4 screws and washers (1). Tightening torque 1.2...1.5 Nm. Connect the plugs of the sensors to the M8 sockets.

• Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

As an alternative the module can be mounted laterally using two M4 screws, tightening torque max. 1 Nm.

To ensure the protection rating

• Cover the unused sockets with the enclosed protective caps. Tighten firmly, recommended tightening torque 0.3...0.5 Nm.

6.1 IO-Link connection

The IO-Link port must be connected according to the IO-Link specification.

The current required by the devices depends on the current load of the sensor supplies.
