One processor - 2 Chassis

Hello
A real quick one. Wanted to use 2 off chassis in a project.
Am I right to think that in studio 5000, I would just add additional modules in chassis 2 through Ethernet Private [0] - Ethernet Private [1] gateway? As image attached:

Yes that would work.
If they're close enough, you can use the rack extension cable, which would save you a couple of £th€rn€t modul€s and two slots.

Rack extension cable! - Didn't know about that - Tell me more please - We're using the 7 slot control Logix chassis and 1756-L71S processor.
Thanks
Mark..

I was wrong there is no 1756 extension cable. Was thinking their SLC range. Two Ethernet modules it is

I would recommend putting your public ethernet card in the main rack. This will make connection to the processor simpler if you connect from public. I have a similar setup in our plant and it held me up for a bit when I tried to connect from my desk. Whenever someone new in our organization tries to connect, we have to set up RSLinx to use the private network ethernet cards to bridge the public to the main rack. It can be done the way you show, it is just a simpler connection to the processor if you move the public card to the main rack.
