Hello,
Sorry for yet another E10 question.
I've seached the web site, documentation and these forums but have been unable to locate the information I am looking for regarding the limitations on the E10.
I am sure its there somewhere but I cant find it.
I know that there is a limit of 4 timers on an E10 but what is the limits for counters? Is it the same? The reason I am asking is I need just 1 extra counter. I have 4 counters but when I add a 5th my program fails to work
The funny thing is, if I leave the 5th counter in the counters list (F2) but just remove all of the references to it in the ladder then the simulation works.
If I then do a simple ladder rung like:
--||--------() Input 1 normaly open, through to counter5 coil.
Then the program will not launch simulation. Ctrl+F9 and nothing happens
Simulate -->> Run (All I/O reset) and again nothing happens.
If I remove the offending rung, the simulation runs and I can see the 5th counter listed (even though nothing references it in the ladder).
Are my issues related to a limit of 4 counters?
Thank you.

Yes, E10 is limited to 4 timers, 4 counters, 8 internal relays.
For a small PLC with orders of magnitude more powerful than E10, try the Nano-10. You have 64 timers, 64 counters and lots of variables that can be used as additional counters.
