Hello all,
I am having some trouble with a device net node and am hoping that someone can point me in the right direction. I am trying to interface a radio remote to a Control Logix processor. I am using a 1756-DNB rev 6 card and the radio remote is the only device on the network. I have used RSNetworx (revision 6) to set up the scan list and map the data but cannot seem to get the communications to hold. The communications seem OK for about 10 seconds then go off and I get a "Device Failure" bit in the processor and an identity failure in RSNetworx. The comms then go back to good for 10 seconds then fail again. I have checked and replaced the calbe several times and have ensured the terminating resistors are in place but still have not had any luck. I also checked out the ground connections and have tried several combinations of no grounds, grouded power supply (0 VDC) with and without the shield and drain grouded but am still unable to fix the problem.
Do anyone have any suggestions of things to check and or try?
Thanks in advance for any help.
