Hi,
I am a very inexperienced PLC programmer. I purchased a Micrologix 1100 and the RSlogix to play with last year. Recently I found an application for it and I like to put it in use.
I like to use it as a watchdog in a bearing test rig. One of the things I like to prevent is over speed conditions.
I have a 2/rev PNP signal and I operate between 0 and 2000 rpm. I am trying to find out how I can use the 20 kHz high speed counter to measure the shaft speed withing 5% of actual speed.
Any one out there with experience with the Micrologix HSC function that have some ideas?
