Click PLC Send and Receive Serial Communication Instructions

Click plc send and receive serial communication instructions that can be used to communicate to external equipment. We will be communicating serially to a temperature controller using Modbus RTU serial RS485.
Receive and Send instructions will allow you to send and receive serial data to an external device. The communication method that you setup can be ASCII or Modbus. ASCII (American Standard Communication for Information Interchange) can be used to send to devices such as a printer. Receiving ASCII can be used for connecting barcode scanners to the PLC. The barcode will be read as an ASCII string in the PLC. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. We will demonstrate the Send and Receive instruction by communicating Modbus to a Solo Temperature Controller. Our example will read the current process (PV) value and write the setpoint value (SV) in the controller.

There are several reasons why we are using the Click PLC. Here are just a few.
- Investment is low for the hardware and the software is free (Low Cost PLC)
- Standalone PLC with built-in I/O
- Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc.
- Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.
