Communication Register List
These integer registers can be used to override the DIP switch address and baud rate settings
and for more advanced communication settings, like even parity or 38,400 baud. See
Communi-
cation Registers (p. 50) below for details.
Registers Name Default Description
1651 ApplyComConfig 0 Writing 1234 applies the configuration settings below.
Reads 1 if changes not applied yet.
1652 Address* 0 Modbus address (if non-zero, overrides DIP switches)
1653 BaudRate* 0 0 = DIP Switch Assigned,
1 = 1200 baud, 2 = 2400 baud, 3 = 4800 baud,
4 = 9600 baud, 5 = 19200 baud, 6 = 38400 baud
1654 ParityMode* 0 0 = N81 (no parity, one stop bit)

1656 ReplyDelay* 5 Minimum Modbus reply delay: 5 to 180 ms
* These registers are preserved across power failures.
Diagnostic Register List
These registers provide information and diagnostics for the meter. These are all integer registers.
UptimeSecs
and
TotalSecs
are 32 bit integer dual registers: the first register provides the lower
16 bits, and the second register provides the upper 16 bits of the 32 bit value. See
Diagnostic
Registers (p. 51)
and
Error Codes (p. 52)
below for detailed information.
