Dear Experts,

I have CPU 313C- 2 PtP and module CP 343-1 Standard and use them to control SINAMIC S110 CU 305PN through PROFINET. In Step 7 V5.5, I use SFC14 and SFC15 to read data from I/Q Address. But when I downloaded program to PLC, it had error "SFC not loaded" and it pointed to SFC 14 and 15. Is it true that in CPU 313C- 2PtP cannot use SFC14 and 15? If true, is there any other way to move data form I/Q Address to DB?

Hope for your answer!

Thks!

hi,

you are using a CP343-1 to communcate over Profinet. Therefor you need other blocks. See this FAQ:

How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?

I guess the SFC14 and SFC15 are not on this CPU because of the CPU can not perform an own DP- or/and PN-system. It has only interfaces for PtP communication.

hope this helps,

regards,
