Serial (RS-485) or Ethernet
When to use 
Serial connection or TCP connection to a Modbus device 
To set up and configure this device in Manufacturing Connect Edge, you will need to do the following:
Step 1: Set up and Configure the PLC Device
Step 2: Set up the PLC Device in Manufacturing Connect Edge DeviceHub
Step 3: Configure the List of Registers
Step 1: Set up and Configure the PLC Device
If you are setting up an Ethernet connection, find the device's network parameters. 
If you are setting up a serial connection, record the serial communication parameters for the device. 
Step 2: Set up the PLC Device in Manufacturing Connect Edge DeviceHub
