Is there an IE table size limit?
Import Export Limits
Using IE is the most efficient way to pass data around a Continuum system, when the tables are full the system will revert to a Point to Point method.
The limits are 255 in the Infinet controllers and 65535 in the CX level controller.
In the CX level controllers, this is for communication to the Infinet network and any peer to peer communication between CX's.
Also see the object limit for the Infinet i1 and i2 controllers that can be found in How many user defined objects can be created in a controller?.
