40021 11 Note address 00 14 Write the network port node address.
Default: 1
Valid range 1 to 247.
Requires a restart to become effective. Note,
both the Modbus Protocol and Johnson
Controls node addresses can be changed via
the display setup menus. r/w
40023 12 Relay pulse divisor 00 16 Write pulse divisor index:
N = 2 to 6 in Wh/10
N .
Default: 3
r/w
40025 13 Password 00 18 Write password for access to protected
registers.
Default: 0000
Read zero. Reading will also reset the
password timeout back to one minute. r/w
40029 15 Network baud rate 00 1C Write the network port baud rate for Modbus
Protocol.
Valid values:
0 = 2400 baud
1 = 4800 baud
2 = 9600 baud (default)
3 = 19200 baud
4 = 38400 baud
Requires a restart to become effective. r/w
40031 16 Energy units prefix 00 1E Write the units prefix for energy output
values.
0 = no prefix (e.g. Wh)
1 = k prefix (e.g. kWh)
2 = M (e.g. MWh) r/w
40033 17 Low power limit override 00 20 0 = limit on 1% symbol off
1 = limit off 1% symbol on
Default = 0 r/w
40037 19 System power 00 24 Read the total system power,
e.g. 3p4w returns System Volts x System
Amps x 3. ro
40041 21 Register order 00 28 Write: 2141 only r/w
40043 22 High serial number 00 2A 0 - 16,777,215 ro
40045 23 Low serial number 00 2C 0 - 16,777,215 ro
40087 44 Relay1 energy type 00 56 Modbus Protocol input parameter for pulse
relay 1:
0 = relay off
37 = Import Wh
38 = Export Wh
39 = Import varh
40 = Export varh
Default = 38 r/w
40217 109 Reset logged data 00 D8 Write 1 to reset energy r/w
Register order
Register order controls the order in which the device receives or sends floating-point
numbers: - normal or reversed register order. In normal mode, the two registers that make
up a floating point number are sent most significant register first. In reversed register
mode, the two registers that make up a floating point number are sent least significant
register first. To set the mode, write the value '2141.0' into this register - the instrument
