For this example, we have created a ConveyLinx-Ai Family Modules in our Ethernet Tree and added a MSG Instruction to a ladder rung. We named this MSG block “ReadZPA” and created the Controller Tag for it. With this MSG Instruction we are going to read all 21 registers from PLC Inputs for ZPA Mode. We also created a Controller Tag called “ZPA_Inputs” which is an INT array of 21 elements in order to hold the data.
