Modbus Offset Register Description
44402 4401 Port 1 output control when used
as an on/off-open/closed switch
0 = Output LOW (closed)
1 = Output HIGH (open) [default]
Register 45110 must = 0 to use.
45110 5109 Digital Port 1 Configuration Turns
pulses on/off
0 = No pulses, Port may be used as an on/off-open/closed switch
44001 = System kWh pulses
44008 = System kVARh pulses
44011 = System kVAh pulses
45111 5110 Port 1 pulse output relay type 0 = Normally open (HIGH)
1 = Normally closed (LOW)
