ProcessLinx TagMap Configuration 3-21
Translation Table To enable scaling for a particular TagMap, you must define and select a
translation table. In runtime, the table converts values from one OPC
Server to valid values for the other OPC Server.
This is useful for converting the discrete mode states of a ProcessLogix
DEVCTL function block an External OPC block. You can define as
many translation tables as needed. The correct translation for the
TagMap is selected from the available list. To define a translation table,
open the TagMap Dialog box (for the TagMap) and click “Settings…”.

deleted.
