Internal Io Failure
Internal communications are lost, device will
act according to shutdown configuration.
Output Board NV Memory
NV Write Deferred:
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 pro-
gram has been written that writes to control
block parameters not normally expected to
be written to on a cyclic basis. Any such auto-
mated write sequence should be modified to
write the 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 Memory
"Output Board NV Memory Failure:
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 Electronics
Output Board Electronics Failure:
Failure
The Device has detected a fault with an elec-
trical 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.
