Description
Description
You can enter a description for the TagMap entry. This field can
be left blank if desired.
IMPORTANT: Commas are not allowed in the description.
Data Flow / Data Master Data Master defines where the data originates when starting
runtime mode. This selection is only enabled when the Group’s
“Data Flow Direction” attribute is set to both directions (
ÅÆ
).
Valid entries are “ProcessLogix” or “External OPC Server”.
Starting runtime mode for bi-directional Groups produces tag
data from both OPC Servers. The Data Master entry eliminates
any ambiguity by initializing the Group’s data using the
selected OPC Server as the source.
Data Conversion
Data Conversion/Scaling provides a method for translating
data. The conversions are stored in Translation Tables. Refer to
to the section Data Conversion / Scaling for details about
creating and modifying translation tables.
IMPORTANT
Each of the attributes described in Table 3.C must be
defined for both OPC Servers in the TagMap.
