Dynamic

Data Type: Bit String

0 = inactive

1 = active

This parameter reflects the error status associated

with the hardware or software components

associated with a block. It is a bit string so that

multiple errors may be shown.

PV_SCALE +/- 10% Dynamic

Data Type: DS‐65

The target block setpoint value. It is the result of

setpoint limiting and setpoint rate of change

limiting.
