Examples 6.8 Software timers 6.8.1 Mnemonics You can program up to 32 software timers in the range between 10 ms and 65535 s. Timer addresses are PT00.00 – PT01.15. Start timer Assignment Address :Time value *Time basis :Function :Remanence *) : R remanence : R raising delay : F falling delay : P impulse : C clock pulse 10 ms (or *100 ms, or *1s 16 bit constant ( 1 – 65535 ) or 16 bit variable (e.g. BM01.02 (+BM01.03 Address of software timer (e.g. PT01.05 ) = Start of software timer at edge 0 → 1, RESET at log. 0 *) Note: Adding the “R” parameter (remanence of current timer value) is optional.
• Read output L PTxx.xx “1“= time run out • Read current value (remaining time) LD PTxx.xx 16 bit value of remaining time • Stop timer =TH PTxx.xx stop without RESET 111
