The Simulator Communication Driver uses a simple item naming syntax. The first character of the item name determines the default data type.
|
Item Name First Character |
Item Data Type |
|
i or I |
32 bit integer |
|
b or B |
Boolean |
|
f or F |
32 bit real (short float) |
|
d or D |
64 bit real (long float) |
|
s or S |
string |
You can override the above default syntax and define your specific item syntax by specifying the appropriate regular expression in the syntax definition file TagSyntax.txt in folder C:\ProgramData\Wonderware\OI-Server\$Operations Integration Supervisory Servers$\OI.SIM\OI.Sim. This file contains definition examples for reference.
Note: Item names not following this naming criteria will be rejected as invalid items at run time.
