Emerson RX3i compatibility with GE RX3i

[BlackBamba]

Hi,
I have a machine running with a GE RX3i system (including a few remote RSTi Profinet nodes). This control system installation is now 10 years old. I'm trying to figuire out what should I expect in case a module needs replacing in the near future.

Do Emerson/reps keep old GE stock?
Are Emerson RX3i modules backward compatible with the GE ones?
Or are we simply doomed...?

Yes they keep old stock.... till it is gone...
However RX3i is same between GE and Emerson.... Just brand name change.

However... I would keep ME updated to current version, so you have current module features.

Ditto what NetNathan said, GE or Emerson, all RX3i's are the same.

Also... about 95% of the GE 90-30 IO modules will plug directly into an RX3i rack and work.
This is a very nice feature.. to upgrade you only need an RX3i Power Supply, CPU and rack, the original 90-30 IO modules are okay to re-use.
