Amr Hassan · October 13th, 2005, 07:13 AM

when coneverting a program that had a call for the fuction mul:16
the conversion tool created a call for fc 83
when i imported the file in s7 and compiled the source an error appeared that the PLC type is not defined . is there a way to overcome this problem?\

Because of the terminology used I guess you're talking about converting S5 to S7. The mul:16 function block in S5 is needed to multiply two integers because S5-100U and 115U cannot do this directly. The S7-300/400 can. Simply replace the mul:16 call by a integer multiply instruction. You should look in the help files, because I don't know what representation you're using.

Kind regards,
