Limitations in mixed systems
Limitations for GE 800
Must be inserted in the top-most GEV ring.
Can only be connected to “ring 1” of a GE 700, no connection to “ring 2”.
If the GE 800 is switched off, the GEV ring does not work (no relay on G8-NET).
Only one GEV connection of a GE 800 system to a GE 700 possible.
Limitations for GE 700
GE 700 network cards must be upgraded to at least software version 5.2.
Limitations for synchronous connections
Works like “Ring 2” (GE 800 is always “Clock Master”).
If CNET-W or CNET-E1 networking is used in the GE 700 system, the GE 800 may only be connected
on one side of the network (see illustration below). Otherwise, non-synchronous connections must
be used (LAN, WAN, S0).
When G8-CNET-W or G8-CNET-E1 are connected to the GEV ring, a connection to a GE 700 is not
possible.
One-sided use of GE 800 in a network with CNET-W or CNET-E1 networking
