i want to control rotation using slc5/05 processor and an encoder AB 845T-DZ33ECK with 360 pulses resolution and channels a,b and z.
Regular inputs and a counter in ladder logic are too slow for pulse counting in plc program...
How can i solve this problem or where can i find ladder example of this or similar program??
Thanks in advance !!!

 

Your situation is what they make the High Speed Counter module for. Part Number 1746-HSCE

 

AB sells an encoder input module.

1746-hsc or 1746-hsce2

Contact your local distributor. They will tell you all about it.
