Hello Fedric,

I think it is possible. But for S7 200 there are no function blocks as in S7 300. So you have to use subroutines as functions. Also you can make library blocks of your own and call them when you need.

I think you cannot pass timer values directly because in temp variables in micro win there’s no data type as timer.
