engineering string mapping. The various analog values received from the Bailey
system are already in a particular engineering unit. Those blocks responsible for
returning exception reported analog values also identify the engineering units
using a predefined Bailey code in the range of 0 – 255. The OPC90 blocks
designed to return these values also include two OPC tags called EU and
EU_TEXT. The EU tag returns the Bailey EU code associated with the analog
value. The EU_TEXT tag returns the Bailey engineering
Use this dialog to define the mapping between Bailey engineering unit codes and
the string to be associated with each code. (Note that engineering unit mapping
can also be defined using the “Import CSV” program feature.) The map is global
to all OPC90 blocks that return exception reported analog values. Use of the
U_TEXT OPC tag is optional. Its purpose is to simplify OPC client display
