Hi all,
I have a 1756 DNB Device net controller with a 1794-ADN DeviceNET Flex IO adapter with 2 1794 - 12 Channel Analog Input cards fitted. The second card is not used. The first 8 inputs of the first card are set to Voltage inputs and the last 4 set to current.
All the voltage ones work as intended. The values are read in ok to the PLC. I get no response on the analog inputs. Both the origianal source has been tested and An analog signal has been placed directly onto the inputs. Pretty sure it is in the configuration. This is a repeat machine and it has worked on the previous set up. The device net networx .dint files from the last machine were used on this one also.
Any ideas, into day 2 of battle now!
