I'm trying to connect 2 compact Logix PLC's to one robot I have ethernet Adv. Scanner/Adp. option on robot. I have generic Ethernet modules setup in each PLC. Each PLC with connect to the robot using different IP address on port 1 and 2 on the robot. But not at the same time though. And they will only connect using slot 1 on the Ethernet setup page not 2,3.4ect is there a way to enable more than one ADP? and more the 1 PLC to be connected? if set slot 2 to true I get a prio-230/232 alarm

This is really a strange idea - having two master and one slave (looks like a pyramid upside down)
Is this the only way to solve the problems you have?
Why do you need two PLC's and what has every invidual PLC to do?

I agree with MOM, this is a pretty strange topology.
That being said, are the PLC's on different subnets?

As a long-shot, try setting the 2nd PLC to Slot #5. In the 2nd compactlogx configuration, you'll have to specify the robot slot "group" to 5-8. I've had to this before but the exact reason escapes me; might have to do with CIP safety but not sure.
A better setup would be to run everything through a single PLC. Let that PLC communicate with the other PLC using produced/consumed tags and pass the info over the single connection, much easier to setup and debug.

Fixed
The issue was input/output assembly instance
Slot 1 is 101/151
Slot 2 is 102/152
The Robot is the master and the PLC's are Slaves they just provide a signal to pick from 2 separate conveyors

Got it. Your OP showed the robot as the adapter. Glad you got it working.
