Hi how are you guys... i was studying the functions of a counter and timer and in the process, i encounter some commands that im not really sure what they mean for Timer:
1. Timer Enable Bit
2.Timing Bit
3. Timing done bit
Im confuse about this, i know how the timer works, but how come they have this in the programming of PLCs like sometimes they put T4:2/2EN
or T4:2/4DN, i mean what is the difference between the 3 of them... same as the Counter command there is a Counter Up bit, Counter Down Bit and Counter Done Bit... thank you for the help
