Practical Tips and Techniques
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
The newest Do-More Designer Programming Software (2.9) version includes a Modbus I/O Scanner. This Modbus scanner will simplify Modbus RTU serial communications to any device. Communications are done independent of the PLC scan time and will have little or no ladder logic for the program. We will be communicating to a Solo process temperature controller … Read more
PLC manufactures have their own proprietary protocols. These methods of communication will allow you to program the controller. Other protocols will allow you to collect and log information from the programmable logic controller. Node-RED has the ability to read and write to the Omron controller using special protocol commands. We will connect Node-RED to the … Read more
Do-more plc modbus ascii protocol will be used to communicate to a Solo process temperature controller. A sample program will explain in detail how this is accomplished through a serial port. Modbus is a communication method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus … Read more
We will now look at the BRX Do-More HTTP JSON instructions in the PLC. One of the features of the BRX Do-More Series PLC is the ability to expand its capability to fit your application. Software and hardware changes are ongoing so the PLC can grow with your needs. Communication is something that the BRX … Read more
Data logging does not have to be complicated anymore. The BRX Do-More Series PLC can log your specific data up to 32 Gigabits on a Micro SD Card. It will store your data for future data analysis in a CSV (Comma Separated Value) Txt file based on time and/or event. This is all accomplished with … Read more
