Click PLC AdvancedHMI Communication

Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. The best thing is that the software is free. We will look at using AdvancedHMI with the Click PLC. Our sample Click PLC program will read the present value (PV) and the indicating lights on our Solo Process Temperature Controller. It will then write the set value (SV) to the Solo. This communication will be done using Modbus RTU protocol over a RS485 serial port on the Click. The AdvancedHMI package will communicate Modbus TCP over Ethernet to the Click PLC. We will be able to monitor our PV and set our SV on the Solo via the AdvancedHMI window.  Keep on Reading!
