Dear friends,
I am writting to you because I ran into a very weird situation from which I cannot see a logical get away.
It is all about an OP177B Touch Screen Siemens operating panel Profibus connected to a S7-300 PLC.
I was working on this bench and it had a stable software version (PLC and OP).
I wanted to do an upgrade on the OP adding two new pages and about 20 variables and 2 text lists. I did the upgrade and i downloaded it to the panel. After the panel rebooted the system I saw a strange thing. I display the pages using a PLC variable. When I wanted to display the 'Manual' page the panel blocked displaying the hourglass.
Another strange thing that I observed was that all the messages and message's pages (service or allarm messeges) weren't displayed.
Hm. an error in the program I said. I double checked my modification, nothing seemed to be wrong. When I tried to redownload the project to the panel, another strange thing: before transfering the files, the panel is always displaying 'Please wait until runtime has been terminated' but in my case the runtime couldn't be stopped. After some time i received a message: keep waiting or terminate now, and only in this way I managed to redownload the project. Anyway, the problem was still there.
Seeing that the problem persists, I downloaded the old software (the stable one, before my modifications). The same result - damn it.
I also unplugged the power supply cable of the panel. - nothing changed (((.
And now comes the bomb. The final solution that could solve the problem was to reinstall the operating system. I used the option 'update operating system' from WinCC flexible. After the system was ready, very happy I downloaded the old version of the project (the stable one). The hourglass is still smiling at me.
Thats it. I am changing my job. I want to become a painter. Enough with all this stress.
Does anyone has an idea? Is there anyway that I can fully format the OP and reinstall the OS from the beggining?
I use Simatic WinCC flexible version 2007 release V1.2.0.0_1.55.0.1
Thanks in advance,
Vlad
