1=Simulate Off ALL
Data Type: Enum (Uint8)
When this is set to 2 all the alert
ACTIVE parameters can be written,
except for INST_ALERTS_ACTIVE.
SHUTDOWN_ALERT_ACTIVE.
This allows alerts to be simulated
for testing with hosts. NOTE: only
ACTIVE parameters are affected by
this. * PWA Simulate is RW only if a
jumper is installed across the Aux
Terminal. If no jumpered is installed
across the Aux Terminal, PWA
Simulate is RO.
