Practical Tips and Techniques
We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs. The send and receive commands … 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
The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. The box selection (camera management and distribution) is one of these machines. It will read barcodes from the boxes and send them to different exit ramps. The Do-More Designer PLC Simulator will be used to … Read more
All Solo Standard Process Temperature Controllers that support RS-485 serial communications can use the SL-SOFT configuration and monitoring software. This free package will communicate to monitor multiple SOLO controllers using Modbus RTU or Modbus ASCII protocols. We will be installing the SL-SOFT configuration and monitoring software package on our Windows 10 PC. Communicating through our … Read more
Node-RED Modbus TCP can recover from communication errors automatically. Options are available to you the programmer to continue the Node-RED flow upon detection of these errors. Broken Ethernet cable, Modbus Server power, and Node-RED Client offline are just a few of the errors that can occur on the industrial plant floor. Our Node-RED program must … Read more
We will be installing a USB to rs485 installation on our computer. The CH340/CH341 USB to Serial port is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and screw … Read more
