Specifications
Energy Sensors:
We distinguish the line sensors (which correspond to the input circuits) and the port
sensors, which measure the energy that is passed over the switched port. The meas-
ured values of the energy sensors are returned as signed 32-bit integers. The high-order
16-bits are starting on the even address, followed by the low-order 16-bits on the odd ad-
dress. To calculate the address, there are the following formulas (the values for line, port
and phase start at zero):
Line: Line * 0x120 + Phase * 0x60 + Offset * 2
Port: Port * 0x120 + Phase * 0x60 + Offset * 2
For devices with only one phase, the phase is set to zero in the formula.
Examples:
"Power Active" for 1st line sensor and 3rd phase: 0x400 + 0 * 0x120 + 2 * 0x60 + 1 * 2 =
0x4C2
"Voltage" for 2nd line sensor and single phase device: 0x400 + 1 * 0x120 + 2 * 2 =
0x524
"Power Angle" for 4th port sensor and single phase device: 3 * 0x120 + 6 * 2 =
0x3d6c
