6.7.40. Comm 1 Framing Errors (29H)
A read indicates the number of Comm 1 Framing Errors that occurred in the slave device. The
maximum count is 65535 and then the counter rolls over to zero and begins counting again.
6.7.41. Comm 1 Total UART Receive Errors (2AH)
A read indicates the total Modbus Comm 1 Receive Errors that occurred in the slave device. The
maximum count is 65535 and then the counter rolls over to zero and begins counting again. The total
errors are an accumulation of the individual communication errors such as Overrun, CRC, Parity and
Framing errors.
6.7.42. Factory Default (2BH)
Writing 1 to this register will load the factory default values for alarm, Modbus and HART settings.
The factory default register is read/write. This command can set all the settings to factory default by
writing 1. A read returns “1” if the factory setting is set default or returns “0” if the settings are different
than the factory default.
6.7.43. Comm 1 Clear error (2CH)
Writing 1 to this register clears all UART receive communication (framing, overrun, parity) error
counters on serial channel 1.
6.7.44. Clear Stats 1(2D)
Writing 1 to this register clears all Modbus (function, starting register address, number of registers,
CRC) error counters on serial channel 1.
6.7.45. HART Current (2E)
Normally in HART mode the low current does not go below 3.5 mA. In order for the current to
distinguish between Fault and offline there is a HART setting that allows the current to go as low as
1.25 mA. A read returns “1” or “0”.

EXCEPTIONS - If an illegal data value is entered (must be between 0-1), then the Exception Code 03
(Illegal Data Value) is returned
6.7.46. HART Present (2F)
HART present is a read only register. A “1” indicates HART is installed. A “0” means HART is not
installed.
NOTE: HART can be installed and not enabled but it cannot be enabled if not installed.
