4.2 NAMING CONVENTIONS

TAG.ATOM Notation

Many applications use the TAG.ATOM naming convention to reference data values. The TAG portion of the
name uniquely identifies the module containing the value. The ATOM portion uniquely identifies which of
the values in the module is to be referenced.

4.2.1 TAGs

4.2.1.1 Types of TAGs

There are three types of TAGnames:

4.2.2 Special Considerations in Using TAGnames

Any unused modules in instruments should have their TAGNAME set to “null”. The easiest
way to do this is to use the Remove Tag function in the Super32 software.

The Micro-PWC DBA applications do not allow the use of duplicate tagnames. The first
occurrence of a tag is used. Super32 recognizes duplicate tagnames and attaches a suffix to
the end of duplicate tags to make them unique.

Although Micro-DCI instruments can store any ASCII character in a tagname, the Micro-PWC
system only recognizes A-Z, 0-9, _ (underscore) and - (dash). All unrecognized characters will
be scanned in as underscores

OPC Client

The OPC Client makes data in OPC servers available to
PC-FTRAN.

OPC
Test
Client

A simple OPC client, useful for testing OPC connectivity.

USER CONFIGURED

User configured TAGnames are Micro-DCI “A” values in the
instrument. See the respective instrument’s Instruction Bulletin to
see if the module of interest has been assigned a TAGname. The
TAGname may be configured using any configuration method
available for the instrument in question, i.e. front panel, hand-held or
the super32 configuration program.

EXTENDED

Extended TAGnames are generated for 53SL6000 controllers. Since
the controller only has a single “A” value (the Unit Tagname),
additional TAGnames are created by adding suffixes to the Unit
Tagname.

NETWORK ADDRESS
TAGNAMES

The System Module of all instruments can be referenced by Network
Address TAGnames of the form “Netname-ia”, where Netname is
the name assigned to the Micro-DCI network and “ia” is the network
address of the instrument (0-31).
