With this lesson, you’ll be able to learn about “ProSoft Technology” product lines, specifically around Modbus communication.
We will also go over how to configure a ProSoft module using their software called “ProSoft Configuration Builder” or “PCB”.
And you will learn how to configure the “Rockwell Automation ControlLogix” controller to read and write to a Modbus device via the ProSoft module.
If you are new to Modbus, you may wish to review a couple of our videos on Modbus:
• What is Modbus and How does it work?

• How does Modbus Communication protocol work?

We will be using the Thermokon Sensortechnik Room Sensor as a Modbus device. We picked this device from the Modbus Organization Website:
https://modbus.org/viewdevice.php?id=391

We will need to get specific interface Modbus mapping documentation from this manufacturer to understand the read and write addresses to use.
We found a document from Thermokon Sensortechnik website that provides us with the device Modbus addressing.
