1.4.19 Total Receive Errors for CH1 (0017h, Read-Only)
A Read returns the total number of Communication Receive Errors that occurred
for Modbus Channel 1. The maximum count is 65,535 and then the counter will
roll over to zero and begin counting again.
1.4.20 Function Code Errors for CH1 (0018h, Read-Only)
A Read returns the number of Function Code Errors that occurred for Modbus
Channel 1. The maximum count is 65,535 and then the counter will roll over to
zero and begin counting again.
1.4.21 Starting Register Address Errors Errors for CH1 (0019h,
Read-Only)
A Read returns the number of Starting Register Address Errors that occurred for
Modbus Channel 1. The maximum count is 65,535 and then the counter will roll
over to zero and begin counting again.
1.4.22 NVM Faults (001Ah, Read/Wrire)
A Read command returns the bit map for any NVM faults that is presently
occurring or had occurred in the past, The following table shows the errors that
are represented by each bit in the register. Table 14. Bitmap for IR4000 NVM
Errors

Error
Event region
HART region
User region
Critical region
Bit Value
8 hex / 8 dec
4 hex / 4 dec
2 hex / 2 dec
1 hex / 1 dec
If there is no Critical region error, NVM faults can be reset by writing 0 to this
register. If any other value is written, data exception will be returned.
Critical region error
means that flash memory is corrupted and the device
needs to be send for repairing.
User region error
means that power interruption happened when one of several
of the following parameters had been set:
Addresses, Baud Rates and Data format for Modbus CH1 and CH2 (registers
0x0F – 0x14), alarm settings (register 0x0D), warn setting (register 0x0E),
number of detectors (register 0x09), number of votes (register 0x0A), HART
configuration (register 0x0C).
Check Setup menu or Modbus register values to make sure that these
parameters have correct values.
HART region error
means that power interruption happened when one of
several of the following HART parameters had been set:
Message, tag, descriptor, date, tag, long tag, short address, final assemly
number.
