UPPERDB 11, 20,
3(), 4(),
5()
A variable limit attribute
which defines the upper
boundary of the deadband of
a limit. The value applies to
a single limit (LIMITID) for a
specified VID. Thus,
UPPERDB and LOWERDB
as a pair define a limit.

9.7 Variable Item Dictionary — This section defines variable data items which are available to the Host for data
collection purposes.
Name: A unique mnemonic name for this variable data item. This name is provided for reference only.
Class: The data type classification (SV, ECV, or DVVAL) of the item. Status values (SVs) always contain valid
information, while data values (DVVALs) may only be valid upon the occurrence of a particular event. All
equipment constants (ECVs) are settable by the Host.
Format: The allowable item format codes which can be used for this variable data item. ...as in Data Item
Dictionary...
Description: A description of the variable data item, with the meanings of specific values. Also, specify validity for
item of class DVVAL.
