Hi, I tryed to monitore from a different ES, but with the same project, as I don't know how can I monitore with a different project. The result was the same. I am modifying the inputs in the CFC chart, follow attached two drawings, the situation before and after modifying the input PHH from 100.0 to 100000.0, as you can see in picture 2 the input PH changed alone from 100.0 to -1.3010e-16. There is communication active, ethernet connection to 2 other PLC's (this is a multiproject). Profibus connection to some other PLC's from package equipment in the field, and communication with the WinCC servers, the reason why I started to investigate this problem and found this, is because the communication with WinCC is not working. A complete compilation and full download is out of consideration for the moment because we cannot stop the PLC. Any other suggestions? Regards, AttachmentFB IO problems.zip (60 Downloads) |
