I'd like to connect my laptop AND proface HMI to an SLC 5/04 1747 L541 so I can look at the bit address of some of the HMI buttons. I don't have access to whatever software is used with Proface HMI to look at the button addressing so I'd like to connect to the controller, smack a button and see which instruction, on what ladder in which rung, goes true. The purpose here is to create a Factorytalk View ME application and get rid of the Proface HMI and replace it with a PVP+ 1000 using the existing RSlogix 500 project.
The problem: I've got only the one rs232 serial port and two things can't be trying to talk through it at the controller at the same time. What's the workaround you guys typically use to deal with this? Is there some way to track whether an instruction has been toggled (by HMI) from a true to false state? I dunno maybe, upload a copy of the project, save it, connect to the HMI, push a button and then upload another copy of the project and use the compare tool to compare the two copies of the project?
I'd like to push a button on the HMI, disconnect the HMI from controller, connect the laptop to the controller and see what the HMI button has changed in the Rslogix 500 project.
