Heey everyone,
I am working whit a Siemens S7-300 and an OP7.
What i want to create is that the Siemens S7-300 does a sort of Diagnostic. In the diagnostic it looks what hardware is has (Digital/analog input, Digital/analog output e.g.). The recieved data from the dignostig must be displayed on the OP7.
I know already how to use an OP7, so if i have diagnostig info, i can let it be displayed. I also know that this Siemens manual explanes that SFC51 and 52 are for reading and writing diagnostics. The biggest question i have at this time is:
HOW do i get the info out of FSC51?
(it seems to have something to do with SSL or SZL, but how or what... i don't know)
maybe am i searching in a totaly wrong way, if someone has a different idea, please tell it also.
