Wizard thank you very much, the pdf is very usefull, I will check my connections tomorow. But the strange is that the corresponding led on the embedded card is on, when the input is hi, without being able to see it in process image. If I had a false in the wiring, then the led wouln't switch on. Is that right? |

I faced same problem in one of my project. . In CPU 313c the +24VDC is not connected on Pin no 1. So though LED is glowing on CPU but i cannot get update in my VAT Table. . This problem get solved after connecting +24VDC on pin 1. |
