Note
1. The maximum number of words for area 1 and area 2 combined must be
no more than 62,000 for optical ring connections and no more than 32,000
words for wired connections or systems that combine optical and optical
ring connections.
2. Data link areas in the Controller Link Support Board are allocated in the
FinsGateway event memory. Refer to the FinsGateway online help for in-
formation on the area types and sizes in event memory.
3. Be sure to delete data link tables for all nodes not participating in the data
