Searched the forums , but didn't see anything remotely similiar so here goes:
I've got a 2 node DeviceNet setup. One is the 1771-SDN on the PLC5 chassis. The other is a Toyopuc DeviceNet card on its chassis.
The Toyopoc DNet card is set as Master, and polls the 1771-SDN for 122bytes read and write. The 1771-SDN is set up as Slave Mode and polled for 122/122. I then setup the BTW/BTR in the PLC5 for 62word block xfer.
I set the channel to Run and the status word indicates that everything is running perfect. All lights on both units are green, no flashing. But when I try to send test data back and forth, nothing.
Now, that in itself is strange, but I've got this system duplicated elsewhere and its working perfectly.
I don't know a lot about DeviceNet network troubleshooting... what should I be looking for as possible problems? At this point I can't pinpoint whether its a card issue or a wiring issue.
Cheers,
