hi guys. Can any one give ma an idea on how to generate 20KHz pulse, using CQM1H PLC of Omron? Also by using S500 PLC of Allen Bradley? Thx....

Both of them have an instruction called PWM is used for this purpose...whether or not it can do 20khz will require reading the manual on that specific unit. I believe either should be capable of 20khz tho.

thanx, guys..
The CJ1M has a better PWM instruction (more adjustable) and also has a PLS2 instruction that alledgedly allows pulses up to 100kHz. I would suggest you have a serious look at the limitations. It may also be advantageous to go to a high end processor which will have a much faster scan time than the lower end models. The cost is proportional of course.
