S7 LAD timer

Alex Pel · Jun 8, 2006

Hello All.

How can I use a variable like MW250 to preset S_ODT timer? When I put MW250 to TV it terns into red color.

Thanks a lot.

Yes it is "TIME_STEP"

The type of the assigned symbol should be "STIME" and it should contain a valid S5T value otherwise it won't work.

Kind regards,

In fact the name of the symbol does not matter, but data type of this symbols does matter, it must be S5TIME

Thank you very much. Actually "S5TIME" works. Also I converted Integer to BCD before use it. The STL instruction - ITB. Looks like Ok.
