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
