8.4.2 PWA SIMULATE
Setting PWA_SIMULATE to ON allows simulating the PWA parameters:
FAILED_ACTIVE, MAINT_ACTIVE, and ADVISE_ACTIVE.
Allowing simulating means that these parameters get write permission, and the
host's written value is the only one which is used for the parameter's read back
value. The data which comes from the transmitter is not used in this case.
8.4.3 Fieldbus/PWA simulate
Use the DD method to enable or disable Fieldbus simulation and PlantWeb alerts
(PWA) simulation.
Use the Transmitter Options method to enable/disable the Fieldbus or PWA
simulation.
Selecting Fieldbus simulation enables both the Fieldbus function block simulation
and PWA simulation. Selecting PWA simulation enables PWA simulation only.
CAUTION
When used improperly, the Simulate feature can alter, disable, or activate
transmitter alarms.
Do not use the PWA Simulate feature for normal operations.
Only authorized personnel should use this feature for testing purposes only.
