WM5-96 Instruction Manual
Programming WM5 96
The serial optical port (d) transmits the data by means of an infrared
device (e-b) . The connection (c) to the PC through the relevant mag-
netic connector (a) is made by means of a USB port (f) or 232 serial
port (depending on the model being used): the user will then be able
to read, transmit or receive information on the WM5 programming (the
WM5Soft software can be purchased on request).
The optical port makes it also possible to retransmit the energy meter-
ing by means of pulses . In this case the light generated by the opti-
cal port is not visible because it’s within the infrared spectrum. Set the
desired type of use of the optical port (energy transmission by means
of pulses or MODBUS or ANSI serial communication) before using it.
Follow steps (1) and (2) on the previous page, then select “OPTICAL”
(2) by means of the “ ” keys and confirm with “S”. Afterwards,
select the type of protocol/communication mode (4) to be used:
ANSI (4) : standard ANSI serial communication protocol. Choose the
ANSI function by means of the “ ” keys and confirm with “S”.
MODBUS (4) : MODBUS serial communication protocol. Choose the
MODBUS function by means of the “ ” keys and confirm with
“S”. Then set the relevant parameters such as baud rate and parity,
see steps
(3b) and (3c) on the previous page.
PULSE (4) : the port will be enabled for the energy retransmission.
Select the PULSE function by means of the “ ” keys and confirm
with “S”. Then select the energy type to be retransmitted (5) , select
ENERGY TYPE by means of the “ ” keys and confirm with “S”.
The instrument will display the list of available energies (5a) (kWh+,
kWh-, kvarh+, kvarh-) (5a) ; select the desired energy by means of the
“ ” keys and confirm with the “S” key: for each energy it’s possi-
ble to choose if retransmitting the total energy metering (TOT) or by
tariff from T1 to T12
(5b) , choose the desired energy detail by means
of the “ ” keys and confirm with “S”. Finally, set the value of the
pulse related to the measured energy, that is the number of pulses
generated for each measured kWh+ (or kWh- or kvarh+ or kvarh-).
Choose PULSE
(5) by means of the “ ” keys and confirm with
“S”, then (5c) set the desired pulse value and confirm it by means of
the “S” key.
Note: set the optical port in the MODBUS mode before using it relat-
ed to the serial communication software “Wm5Soft”.
