Support Questions / Advanced HMI interface to Automation Direct BRX PLC
« on: November 15, 2023, 08:29:13 AM »
Hello,
I'm looking for something that seems to be hard to find. I am using VS 2023 and Advanced HMI together with an Automation Direct BRX PLC using the MODBUS protocol. It works pretty good: I can use AdvancedHMI's Basic Button from the toolbox for example and it gives me options such as "PLCAddressClick", "PLCAddressVisible" and so on. On the BRX PLC side it uses discrete MODBUS bits named MC and MI, so that the PLC can communicate with the AdvancedHMI BasicButton.
What I am looking to do now is use a timer inside VS (like a small C program) and control an MC MODBUS bit inside the PLC. I am trying to build in like a watch dog timer. The problem I run into is that there is no timer inside the standard AdvancedHMIControls Components Toolbox. The only timers I find are the ones in the "All Windows Forms" and the "Components" Toolbox sections and those do not have PLC Address properties associated with them. Could anyone point me into the right direction as to how to approach this? Basically all I want to do is control a PLC MODBUS input with a blinker or timer inside VS.
Much appreciated!
