When using a CPX-AP-x-4IOL-M12 module on an EtherNet/IP network, it is recommended to use the non-OE Variant for selecting the port size. This way, you won’t have to deal with OutputEnable.
When configuring the ports of an IO-Link master like CPX-AP-I-4IOL-M12 or CPX-AP-A-4IOL-M12, you will come across a parameter that specifies the number of bytes reserved per IO-Link port, known as the Variant.
Let’s discuss setting up an IO-Link module for 2 bytes per port in an EtherNet/IP (EP) network. As shown in Figure 1, we have two options: Variant 2 and Variant 2_OE, both of which are supported on EP. The main difference lies in the output size, with Variant 2_OE having an additional 4 bytes.
