Hi everyone.
Just finished my PLC ladder code for my new E10+relay. I am Really happy with it. I ended up needing more timers than were available but I managed to work around that by making some of the available ones generic timers and an internal relay coil opening/closing different rungs of ladder as needed.
So from the documentation, the timers by default are 0.1s decrements yes? I also read that a value of 1000 = 100 seconds.
So by my calculations, max value (9999) is about 16.7 minutes? Not exact, but close enough. Did I get that right or did I calculate that wrong? (10000 / 10)/60 = 16.6667
Anyway I started a timer in simulation mode (WinTrilogi) and monitored it with my PC clock. After the timer expired I calculated the time to be 17.5 minutes. I did this a few times to check my results. Each time, a timer with the value of 9999 would take about 17 and a half minutes.
I would like my actual PLC timers to run as close to 4 hours and another as close to 30 minutes as possible. I was wondering if anyone could confirm for me that the timer in the PLC will be 16.7 minutes like I calculate or closer to the 17.5 minutes like the simulation mode shows? Keeping in mind that I am using counters to extend the range of my timers.
I am unable to load ladder onto my PLC to test at this point in time as I am in another country.
I presume the difference has to do with the software implementation in simulate mode. Maybe something to do with weired numbers like 1024
I would just like to get my code as close to perfect as I can so it is ready to upload to my E10 when I go back home in a few more days.
Thanks,
Woody
