S7 Timer Bit

[mhi 2]

Before this i familiar with AB, each timer in AB we can see status for 'Timer done bit' and 'Timer run' eg. T4:0/DN and T4:0/TT. What about S7 is there any status bits for it? I use Ladder Thank you.

Hi, Dont know ur plc & software ur using If 200 / Microwin u can't expect this running bit only done bit after timer completion. If 300/400/1200/ET200 the timer on status & timer completed status can be monitored.. C the images for details Timer Bits img show that the timer was on & Timer bits 1 show s that the timer was on & done bits IN - On or Running Bit Q - Done Bit Hope it helps, Nelliyan.G
