IOLM 8-EIP Connecting Devices

You can use the IO-Link Master Library for EtherNet/IP and Modbus/TCP or the following information to connection IO-Link devices to the IO-Link Master.

The IOLM 8-EIP provides eight IO-Link ports with M12 connectors (5-pin female/A coded).

Note Make sure that you tighten the cables properly to maintain IP67 capabilities.

This table provides signal information for the IO-Link connectors.

The C/Q pin for the IO-Link ports in SIO mode for all models:

The following table provides definitions of the terminology used above.

Term	Definition
PNP output	Is an output that can source current. That is; the (+) side of the device is connected to the output and the (-) side of the device is connected to (-) of the supply. The device is powered when the output LED is on.
NPN output	Is and output that sinks current. That is: the (-) of the device is connected to the output and the (+) side of the device is connected to (+) side of the supply. The device is powered when the output LED is off.
Sinking input	Sinks current into the IO-Link Master so a positive voltage will cause the input to turn on. Note Using NPN with inputs is not correct as NPN described an output situation – however some vendors describe their inputs as accepting a certain type of sensor output - so in this case a sinking input will accept a PNP output sensor.

This table provides information that you may need regarding the IO-Link connectors. The IO-Link Master Library for EtherNet/IP and Modbus/TCP contains specifications for power sharing/budgeting L+/L-.

Note IO-Link ports must have an approved cable or protective cover attached to the port guarantee IP67 compliance
