Counter limits in LDMicro (by Ziggy)
What are the speed limits of a counter under LDMicro?
Is there a high speed counter option?

Hm.. no comments so far.
I guess I was a bit vague in my posting. Let me clarify. Given a ladder cycle setting of say 1 milisecond what is the maximum input frequency from an external source into a counter? Is there an option of a high speed counter which would not be limited by any of the ladder configuration settings?

The max speed at 1ms = 500HZ -> ( 1:0.001 ) : 2
Cycle setting 0.2ms = (1 : 1.0002) : 2 = 2500 Hz max Otherwise you need a prescaler

Sorry typo, second line must be (1 : 0.0002) : 2 = 2500 Hz

MGP,
Thanks. I had visions of the counter being limited by update cycle but I had also hoped for a high speed independent of cycle time counter capability.
