Range Default Value Description
Static Revision
ST_REV
1 RO 0 to 65535 0
Data Type: Uint16
The revision level of the static data. Increments by
one each time a static parameter is written. The
value is reset to 0 whenever a Restart with
Defaults is performed.
Tag Description
TAG_DESC
2 RW NULL
Data Type: String
The description of the block.

Data Type: Uint16
Used to help group blocks.
Alert Key
ALERT_KEY
4 RW 0
Data Type: Uint8
The identification number of the plant unit.
Devices in a loop or plant section can be assigned
with a common alert key to aid the operator in
determining location of alerts.

Data Type: DS‐69
The actual, target, permitted, and normal modes.
Target: The requested block mode
Actual: The current mode of
the block

2
Data Type: Uint8
Ideal decimal places shown. It could be less if
decimal places need to be sacrificed to display
digits left of the decimal point. If that becomes a
problem, consider changing display units.
