Here we will go through an example of setting up the ZP-L Distance Measuring sensor to communicate with Omron NJ/NX series PLC.
Input and Output tag sets
Between an EtherNet/IP scanner and a Communication Unit, I/O data exchange is performed with tag data link communications. This means that the I/O data for a Communication Unit is defined with input and output tag sets.
