One or more spaces or tabs should separate the fields of bus code definition. The
maximum length of one row is 125 characters and there must be <CR> <LF> at the end
of each row. Both uppercase and lowercase letters can be used.
The Unit Definition File can be created and edited by some text editor (e.g. MS Notepad)
or also by MS Excel. In second case the Unit Definition File must be saved as a text file
(“Unit.txt”) by using tabs as delimiters of columns and then renamed to “Unit.def”.
If SPA Server has problems on processing of the Unit Definition File, all warnings and
errors will be logged to the Wonderware Logger and/or SPA Internal Logger.
Using the SPA Server with Suite Link and DDE
Clients
The “Suite Link & DDE” version of SPA Server is accessible from Suite Link clients (e.g.,
InTouch) and DDE clients (e.g., Excel).
Using the SPA Server with InTouch
To access to items on SPA bus devices from InTouch, the Access Names and Tag
names should be defined in WindowMaker.
Defining the Access names
InTouch uses Access Names to reference real-time I/O data. Each Access Name
equates to an I/O address, which can contain a Node, Application, and Topic. In a
distributed application, I/O references can be set up as global addresses to a network I/O
Server or local addresses to a local I/O Server.
To define the Access Names in WindowMaker node invoke the /Special/Access Names...
command. The "Access Names" dialogue box will appear.
