rb_NV_write_deferred Output Board NV
Memory Failure
NV Write Deferred:
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 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 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.
nnn nyy
rb_nv_memory_failure Output Board NV
Memory Failure
Output Board NV 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.
yyn nnn
rb_nv_electronics_failure Output Board
Electronics Failure
Output Board Electronics Failure:
The Device has detected a fault with an
electrical component on the Fieldbus
Electronics Module Assembly. Replace the
Device.

diag_opt_PWA_simulate PWA Simulate
func_opt_simulate Simulate Switch Since the hardware simulate switch may be
impractical to access, a software option is
being provided.
misc_opt_base_record 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.
