Communication between NX PLCs

[DonNH 3]

So I have (1) NX102 and (2) NX1P2's on conveyor units which support an Omron AMR.  Communications between the PLCs and the robot are handled using Omron's standard ARCL function blocks.

I'd like to have some communication between the PLCs - mostly checking sensors & status variables, possibly triggering minor actions.

Poking around the manuals and some of the Youtube videos for communications, but looks like there's lots of options, and am looking for a simple way to pass basic info between the PLC's, all of which are on the same VLAN on our network (all have IP addresses of 172.16.209.xxx).

Any suggestions on where to start?

EtherNet/IP Tag sets.  Set them up on each PLC, one to transmit, two to receive.  Ideally, create structure types with the content to transfer.  (This is similar to Rockwell's producer/consumer tags, and uses the same class 1 I/O buffer technology.)

Thanks. I'll play with that.  
I also just found some of the Omron webinars on Youtube that I hadn't come across before, one of which covers networking, so I'll be reviewing that -
