Hello

I have been working on S7-400H system with CPU 410-.Now I wana see all LED's status on my wincc. that is which CPU is master,which cpu have what type of fault(Only Cpu LED's fault) etc??? 

I am working PCS7 9.0 Sp3 software so please let me know if nay block in PAL library?

Hi Atul Gupta,

the APL has no block, which shows the information about the CPU status in WinCC. These information is only available with the Maintenance Station (see the Manual PCS 7 Maintenance Station at the chapter "AS/System" area). But you don't have to worry for the Maintenance Station Basic you don't have to buy additional license (For the different version of the Maintenacnce Station see the Manual PCS 7 Maintenance Station at the chapter Application, version and configuration).

With regards
Heisenberg
