Reg
(Hex)
8C10 1 The instance number of the pulse output R/W
8C11 1 The physical I/O port on which the
pulses are sent out
8C12 3 The OBIS code for the quantity
8C15 2 The pulse frequency, measured in
pulses/kWh with 3 decimals. This is
relevant only if Energy quantity is set to
active energy.
8C17 2 The pulse frequency, measured in
pulses/kvarh with 3 decimals. This is
relevant only if Energy quantity is set to
reactive energy.
8C19 2 The duration of a pulse, measured in
milliseconds
8C1B 1 Write the value 1 to this register to turn
off the chosen pulse output instance
Action
Choose the pulse output instance to configure by writing a number to the Pulse
output instance register. Allowed values are 1-4.
Write to the Port number register to decide to which physical port the pulses are
sent out for the chosen pulse output. Allowed values are 0-4, where 0 means
No Output.
Write the OBIS code of the quantity that shall be used for the chosen pulse
output to the Energy quantity registers. Possible OBIS codes are listed above.
