I have a machine that I'm thinking about installing a PLC to control it's functions.
The machine uses a single output pulse generator attached to a shaft that the PLC would have to engage a clutch count the pulses till preset then remove the power to the clutch so I'm thinking High Speed Up Counter.
The other section of the machine would use a Quadrature encoder to determine machine angular position and turn on outputs based upon machine position.
Here is the thing I have a Micrologix 1500 out os use at the moment that is available. The base I have for it is the 24BWA base which from the documentation has 4 (20KHz) high speed inputs but the processor has two High Speed Counters. I was also reading somewhere that implied that inputs 0-3 are HSC0 and inputs 4-7 are HSC1; if this is correct would I then need a different base or would I be able to use the 4 inputs that I have for both counters?
