[quote user="thuynguyet"]Hi all, I'm trying to count pulses from an encoder using high speed counters on CPU 313C 2DP. Connecting encoder pulse input to the first DI on CPU (I124.0 ???) and calling SFB47 with addr 16#300 (768), channel 0, setting also HW on Count continuously and Count pulse but I still get nothing (count always = 0!) I've downloaded the example too (for 313C 2PtP), changed the CPU and tried but ... the same things! SW gate and HW gate were also tested but no result! Please help! What'd be wrong? Hello thuynguyet, The first DI on CPU (I124.0) is the pulse input, the second DI (124.1) is the direction and DI (124.2) is the hardware gate. Do you use the Hardware gate? If not you should use only SW gate to start or stop counting. You have put 24Volt on pin 1 and 21 and put ground on pin 20 and 30? I guess you have seen the following manual: http://support.automation.siemens.com/WW/view/en/12429336 You also have seen the examples, you can download from here Best regards, Wizard |

Thanks very much for early help, Wizard I'll check it all. Do you know if we can test this on Simulation? |

Hello thuynguyet, I'm not sure, but I think you cann't simulate. Best regards, Wizard |

I'm not sure what's wrong, but it's ok now. [:blush:] Any way we can't test it on Sim. Thanks very much, Wizard. |
