Data objects for controllable status information

Controllable single point (SPC)

The command sequence for controlling points is specific to each relay. In the 2000 R
products, for example, SPC is implemented using a bit mask.
TRUE/FALSE values are sent with 1 and 0 values.
Underlying protocol converter stack uses Motorola convention in binary value usage.
Used OPC Server sees OFF data with value 0 and ON data with value 1 from stack.
Modbus value
0 (OFF default)
1 (ON default)
