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. More information can be obtained on our website.
