# Modbus Saia Burgess Controls Binding

This binding interfaces the energy meter series ALD1 by Saia Burgess Controls (SBC) via Modbus.

# Supported Things

The following Things are supported:

  • ald1Unidirectional: 1-phase 32A one-way energy meter ALD1D5FD00A3A00
  • ald1Bidirectional: 1-phase 32A two-way energy meter ALD1B5FD00A3A00

# Discovery

This binding does not support discovery.

# Thing Configuration

The following configuration parameter applys to ald1Unidirectional and ald1Bidirectional.

Name Description Type Required
pollInterval Time between polling the data in ms Integer yes

The Thing needs a Modbus serial slave Bridge to operate.

One of the following serial settings need to be configured in the Bridge:

  • 9600 baud, 2 stop bit, no parity
  • 9600 baud, 1 stop bit, even parity
  • 9600 baud, 1 stop bit, odd parity

# Channels

The following Channels apply to ald1Unidirectional and ald1Bidirectional if not stated otherwise.

Name Type Description
total_energy Number:Energy Energy Total
partial_energy Number:Energy Energy Counter Resettable (only unidirectional meter)
feeding_back_energy Number:Energy Energy Feeding Back (only bidirectional meter)
voltage Number:ElectricPotential Effective Voltage
current Number:ElectricCurrent Effective Current
active_power Number:Power Effective Active Power (negative numbers mean feeding back)
reactive_power Number:Power Effective Reactive Power (negative numbers mean feeding back)
power_factor Number:Dimensionless Power Factor
