40025 13 Password 00 18 Write password for access to protected
registers. Read zero.
Default: 0000
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 = k (e.g. kWh, but Ah for ampere
hours - default)
1 = M (e.g. MWh, but kAh for ampere
hours) r/w
40037 19 System power 00 24 Read the total system power,
e.g. for 3p4w returns System Volts x
System Amps x 3. ro
40041 21 Register order 00 28 Write the value 2141 in the required
register order. r/w
40043 22 Serial number Hi 00 2A Read the first product serial number. ro
40045 23 Serial Number Lo 00 2C Read the second product serial number. ro
40087 44 Relay 1 energy type 00 56 Write MODBUS Protocol input
parameter for pulse relay 1
0 = relay off
37 = import Wh
39 = import varh
Default = 37 r/w
40089 45 Relay 2 energy type 00 58 Write MODBUS Protocol input
parameter for pulse relay 1
0 = relay off
37 = import Wh
39 = import varh
Default = 37 r/w
40217 109 Reset logged data 00 D8 Write code to reset data group.
1 = energy
2 = demand maximums
3 = demand maximums and demand
time 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 will detect the order used to send this value and set that
order for all Modbus Protocol transactions involving floating point numbers.
It is perfectly feasible to change EngyVolt devices set-up using a general purpose Modbus Protocol
master, but often easier to use the device display, especially for gaining password protected access.
