Ethernet IP

51Mag

I'm trying to connect a compact controller (Master) to a Standard controller(Slave).  The Slave has a Ethernet IP fieldbus adapter and the Master has the Ethernet Port.  I have the options

841-1 Ethernet/IP M/S

905-1 Ethernet/IP Port

on both controllers as well as the Fieldbus adapter on the slave. 

 

I can't get them to talk.  I have them connected through a hub but I can't get the green lights on the fieldbus adapter to go solid green, they just flash green.  On the slave I can see the signals I have setup but on the master I get an "x" in the value instead of a 0 or 1. 

 

Does anyone have any experience with this.  I have followed the manuals by using the EN_Slave on the master and the EN_Internal_Slave on the slave.

 

thanks

I'm assuming this is IRC5 with an AB CompactLogix controller. Hope this helps:
