I am programming in SCL and am finding it difficult to find out the structure of the function call. When in ladder there is an option for EQ,GE,LT, etc but no info on how this is achieved in SCL. Any ideas ?

Any ideas ? In S7-1200 SCL, FW 3.0, I put this in an FB: [code]IF #t2 > #t1 THEN ; // t2 > t1 ELSE ; // t1 <= t2 END_IF;[/code] It seems to compile and compare t1 & t2 which are configured in the interface as Time_of_Day datatypes. This is S7-1200 SCL which does not have the T_COMP instruction listed in theinstruction pane.
