Hi All,
I'm having a problem with a 1747-SDN devicenet scanner module. The network which its on is small. Only two other nodes, both partlow PID loop controllers (MLC9000). There had originally been 3 nodes - a speed drive along with the two PID controllers. But we wanted to remove this as we were replacing the drive and were going to use normal analog signals. I did this - using rsnetworx and a 1747 sdnpt driver. I connected to the scanner through the backplane and removed the speed drive from the scanlist. However, the module still shows a fault, the same fault it had been showing all along. The module status light flashes red, the netword light is solid red and error 91 shows up on the screen, a bus-off error if im correct. The network itself seems fine, each end has been terminated with 120ohm resistors, dnet power seems good, shield is grounded, each node has the right baud and node number configured. Could anyone shed some light? Thanks in advance.
Matthew.
