AB7668-F flashing red MS light - problem with configuration?

[RyanP]

I am trying to get the Ethernet/IP scanner on a AB7668 configured to interface with a UR robot, but I’m having difficulty figuring out the proper configuration settings.

I have the following information from UR:

Output size(byte): 480
Input size(byte): 224
RPI: 8 [This one can be very low as we can do 2ms on the E-series]
Input Assembly: 100
Output Assembly: 112
Configuration Instance: 100
Output Run Program Header: 1 (may not need)
Input Run Program Header: 0 (may not need)

and I’ve tried to match that in the web configuration settings:
settings2.bmp (2.0 MB)

and the configuration manager
Scanner.url (132 Bytes)

I’ve tried other settings as well, but whatever settings I use I get a red blinking MS light (as opposed to the green flashing light I got when it wasn’t configured at all).

I can’t even get it out of idle mode: When I try to set Operation mode using the Anybus Manager I get

Hopefully you can give me some guidance on what I’m doing wrong!

Hello RyanP,

One thing that stands out is the config and the input assembly instance is the same. I would recommend double checking this. You could also try 1 which is a common config instance.

Another issue could be that the input and output terminology is swapped. you could try reversion the input and out but assembly points and their sizes.

If this does not work I would recommend getting a wireshark capture between the scanner and the client. The capture should show the request and the EIP error response giving us a better idea on what is wrong.
