Dear PLC Gurus,
I don't want to beat this topic to death by I need to read the RPM accurately from 4 pumps using a MicroLogix 14000. I have read many posts about the RPM topic thing and decided to test what results I would get.
I am ready to use a HSC for that purpose reading a 60 PPR encoder, but before commiting to use a PLC, a decided to setup a RPM simulator on the ML1400 using the known frequency of the free-clock-scans to simulate the encoder pulses.
I have mixed reviews of the results I see in real time.
I would appreciate experienced programmers take a look a the attached files:
1) RPM.RSS - RPM Simulateor. Easily adaptable to other AB PLCs
2) RPM.pdf - A starting location for anybody to use and try this simulator.
3) RPM.xlsx - Collected samples of a variety of simulations paged by RPM.
Files from items 2 and 3 were zipped into a RPM.zip
I hope someone can look at this stuff and tell me if what I obtain is correct or if I need to make corrections somewhere, or use a different approach altogether.
