Click PLC Modbus ASCII Protocol

We will now look at the click plc Modbus ascii protocol. This communication will happen in PLC ladder logic and communicate through the serial port (RS485) to a Solo process temperature controller. Modbus ASCII will be the communication protocol. More information can be obtained on our website. This includes all of the links mentioned in this video. https://accautomation.ca/click-plc-modbus-ascii-protocol Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master (Client) and the devices supplying information are Modbus Slaves (Servers). This protocol was originally developed by Modicon systems. Modbus protocol comes in basically three different types. Ethernet (Modbus TCP) or Serial (Modbus RTU or Modbus ASCII). Modbus TCP and Modbus RTU come as standard protocols in the productivity series of PLCs. We will connect the Click PLC to a Solo process temperature controller. This will be done using the Modbus ASCII protocol over serial RS485 communication wire. (Media) The present and set values (PV / SV) will be read from the Solo controller and the set value will be written when required. Let's get started.

Here are just a few. - Investment is low for the hardware and the software is free - 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. https://www.accautomation.ca
