CQM1H PULSE OUTPUT

[rduen 0]

Hi, need your help please.. I tried to output pulses in CQM1H using SPED instruction. I set D=000,M=1,F=20. I also set DM6615=0000. Nothing happens when I execute the program.

My first guess is that you need to change the F to #20 to designate a constant value of 200 hz. By setting "20" the plc is trying to use IO channel 20 for the pulse value. Very good possibility that IO channel 20 value is zero (0). Hope this helps.
