FX 1n parts / min

[bodyx]

Hello, if you can give me to me a concrete example FX1N PLC ladder format, I tried and function specific SPD but without satisfactory results. If you are kind enough to help me thank you very much.

you did not mention what would satisfactory result be, what is frequency of the parts, what update time would be appropriate etc. SPD instruction is more appropriate for high frequency pulses. parts are usually much slower, maybe this gives you an idea: http://forums.mrplc.com/index.php?showtopic=25523&st=0&p=123030entry123030
