I am trying to extract an existing program from a Siemens TP170A HMI, using ProTool CS. Thus far, I have been unable to establish communication between the desktop computer I am using and the panel.
My fear is that they will not talk unless the HMI is in configuration mode, which is the real problem as the HMI has a non-functioning touchscreen.
Is there any other way to get the panel into configuration mode? Or am I just missing something simple here?
Thanks in advance,
JMC
