Hello eliasd, Let's try something else. The CPU has two connectors. The one at the left is for Analog I/O and last byte of Digital inputs (the one you can read in) The second connector at the right is for Digital Inputs and Outputs. (Left are inputs and right are outputs) Can you confirm you are using the right connector (X12) At the attachment you will find the wiring. (page 21) Best regards, Wizard Attachments7300_cpu314c_2_pndp_product_information_en-US_en-US.pdf (145 Downloads) |

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. |
