Internal IO failure alert
Internal Io Failure Internal communications are lost, device will act
according to shutdown configuration.
Output Board NV NV Write Deferred:
Memory Failure A high number of writes has been detected to
non-volatile memory. To prevent premature failure
of the memory, the write operations have been
deferred. The data will be saved about every 3
hours.
This condition usually exists because a program
has been written that writes to control block
parameters not normally expected to be written
to on a cyclic basis. Any such automated write
sequence should be modified to write the
parameter(s) only when needed.
It is recommended that you limit the number
of periodic writes to all static or non-volatile
parameters such as HI_HI_LIM, LOW_CUT, SP,
TRACK_IN_D, OUT, IO_OPTS, BIAS, STATUS_
OPTS, SP_HI_LIM, and so on.
PWA Simulate Active If PWA simulate mode has been activated.
The PWA active parameters can now be
written as well as the resource block detailed
status parameters and the internal alerts in the
Transducer Block where the PWA active alarms
originate from.
Output Board NV Output Board NV Memory Failure:
Memory Failure "Non-volatile EEPROM data corruption was
detected on the Fieldbus Electronics Board.
Default values were loaded into the faulty block.
1. Check the device configuration for changes in
the block parameter values.
2. Reset the device to clear the error.
3. Download a Device Configuration.
NOTE: If the failure reoccurs it may indicate a
faulty EEPROM memory chip.
Output Board Output Board Electronics Failure:
Electronics Failure The Device has detected a fault with an electrical
component on the Fieldbus Electronics Module
Assembly. Replace the Device.
PWA Simulate
Simulate Switch Since the hardware simulate switch may be
impractical to access, a software option is being
provided.
Base Record When the base record option is enabled, operator
can write/read parameters to/from the sensor
board that are not available via the FF parameter
list.
