I've got an error when compile OS in multiproject: "The number of parameters for the structured XXX type ProjectName/CharrtName/InstanseName DM variables does not match the number of operable I/Os". The problem appeared after I added attribute 's7_m_c' for two TIME variables and compiled SCL source and CFC. If I remove 's7_m_c' from that two variables, everything goes well and OS compliles without errors. - PCS 7 v7.1 SP3 - S7-SCL v5.3 + SP5 P.S. I compile OS as Entire OS with memory reset. How to solve this proble? Is it bug orfeature?)

Or ist just aREAL or INTEGERvalue which contains a count of seconds? If my first question is true, I think it is not possible to transfer the types TOD and DT directly to WinCC. Here is a way how to do that: Link In PCS7 you are usally not using timers. You create a time in your source codeusually by counting the calls with considering 'sample time'

CFC convert TIME varible to SignedWORD, you can see it if open Operator Control and Monitoring in CFC in Adapt Format column. Try it. It realy works) The real problem is error "The number of parameters for the structured XXX type ProjectName/CharrtName/InstanseName DM variables does not match the number of operable I/Os" appears whenfor exampleI have following interface in SCL: VAR_INPUT a {s7_m_c:='true'} : BOOL; END_VAR VAR_IN_OUT b {s7_m_c:='true'} : BOOL; END_VAR VAR_OUT c{s7_m_c:='true'} : BOOL; END_VAR Then I compile and transfer it to WinCC. After that I decide to change my SCL code as following: VAR_INPUT a {s7_m_c:='true'} : BOOL; b {s7_m_c:='true'} : BOOL; END_VAR VAR_OUT c{s7_m_c:='true'} : BOOL; END_VAR I transfered variable "b" from IN_OUT to INPUT. I compile OS and error appears: "The number of parameters for the structured XXX type ProjectName/CharrtName/InstanseName DM variables does not match the number of operable I/Os" That is the real cause of this fault. Does anybody knows how to avoid this trouble?

I mean delete the input of type I/O,compile OS, then add the input as IN and then compile OS again
