The Productivity 2000 series of PLCs has five built-in communication ports for easy connectivity to your PC or various industrial networks. Serial protocols like Modbus RTU can be utilized with the RS232 or RS485 ports on this PLC. Modbus RTU (Serial) is an open (published) protocol that uses the Master / Slave architecture. It’s a widespread protocol used in industrial automation controls.
We will use the RS485 (2-wire) port to communicate to a Solo Process Temperature Controller. Modbus RTU will be the protocol used on this serial communication media. The PLC will be the master, and the Solo process temperature controller will be the slave. You will soon see how the Productivity Series of PLCs best handles communication with other devices. Let’s get started.
