10.1.6. Setup the Transacons
Set up the communicaon between the node and the master.
In this example, the communicaon between the Temperature Regulator and the PLC.
The Temperature Regulator has two Modbus transacons:
• One registers holding the setpoint temperature.
• One registers holding the actual temperature.
Congure the temperature setpoint transacon

1. Select the Temp Regulator node.
2. To add a transacon, click Add.
3. Select the transacon to congure.
4. In the transacon sidebar, on the right side of the screen.

The PLC writes a block of conguous registers to the temperature regulator.
Address/ Register Address: 0
Register: 1
Address 0 is Register 1.
Quanty 1 The transacon will address one data object.
