Hi,

I've got a problem with my network. I have SLC 500 processor, 1747 SDN Device Net scanner and Control Techniques MENTOR II DC drives.

The problem is that even after I've shut down the MENTOR II (error appears on led indicator on SDN error code 78 for node with MENTOR II ) I still have its status word available on my Device net scanner input word (without any change I mean the same word as a MENTOR II propely working).

Please answer A.S.A.P

Best regards
Jacek & Slav

 

I think but need to test this that once a node is gone from the network you have to add ladder to check the scanner, I check normaly if the drive has power, so I'm not 100% sure.

If you want to contact me.
