[Teropod 0]

I would like to add some code lines in program but i dont wanna increase my cycle time! Do plc run rungs in SBN(092) if it isnt called? Cant configure that from manuals. Thanks!

Instructions within a subroutine are not executed when the subroutine is not called. That's the whole idea behind the concept of a subroutine! BUT when you call the routine it WILL change your overall cycle time.
