Hello I have a system 3 years old with 2 TP1500 Basic Panels V12 and a S7-1500 that has been configured and working fine in TIA Portal V13 and V14. I upgraded to V15 and did some modifications to one of the TP1500 Basic panels and now NEITHER HMI will communicate to the S7-1500. Also tried running the HMI application on a WinCC Runtime Advanced PC and same problem- no communication. There doesn't appear to be network communication issues, just can't operate anything from the HMIs. Ideas much appreciated! Attachment1-7-19.xlsx (43 Downloads) |

Connections appear the same as before when system was operating normally. As mentioned I can go online with HMIs, seems like the tags are frozen. |

Found it- PLC settings under protection and security defaulted to no access (complete protection) somehow- strange. |
