AdamEMC posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareHi I am new to visilogic and PLC's in general so excuse me if my question is a simple one. My PLC is a Vision 130, which has high speed inputs and outputs. I understand that with the use of PID function blocks you can produce a PWM output signal but I am looking to interpret a PWM signal from a device to the PLC. The device is a synchronisation relay to synchronise a generator to the grid. It produces the following: data is pulse width modulated SYNC: 8ms high 1: 4 ms high 0: 2 ms high ; a data packet consists of 10 bits data: first sync 8mS high then b0-b1-b2-b3-b4-b5-b6-b7-b8-b9 I want the controller to be able to read this 10bit data packet so I can use its analogue value within the program. Is this possible with the high speed inputs I have or will I need to convert the PWM signal to an analogue signal seperately and just use one of the analogue inputs on the PLC? Thanks in advance Adam
