Practical Tips and Techniques
90% of industrial automation systems use Modbus for communication. This open standard protocol is used for everyday applications, including monitoring and controlling equipment such as PLCs (Programmable Logic Controllers), remote terminal units, sensors, and more in automation and process control environments. RS-485 typically utilizes twisted pair cables, which consist of two insulated copper wires twisted … Read more
Using Modbus RTU (RS485), we will connect the XY-MD02 Temperature and Humidity Sensor to the Click PLC. The Click will be the Client (Master), and the Sensor will be the Server (Slave). This is an ideal sensor to place in a panel to ensure that the panel is within a working temperature and humidity range. … Read more
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. Modbus is a communication method used for transmitting information over serial lines between electronic devices. The … Read more
Suppanel is an Android app that is used to create a human machine interface (HMI). This HMI panel can be created on your computer, tablet or phone using the appropriate operating system or software. You can use this software to create panels that you can control or modify values in your automated system. These panels … Read more
Recently I was asked to demonstrate communication between a BRX PLC and Click PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many automation devices. It works on a Master / Slave configuration. You can have only one master per network … Read more
We will now use Modbus RTU to connect a Click Master to a BRX Do-More Slave controller. Recently I was asked to demonstrate communication between a Click PLC and BRX Do-More PLC using Modbus RTU. Both PLCs are available from automation direct com. Modbus serial communication (Modbus RTU) is a standard protocol used in many … Read more
