External Sensors:
The measured value of the external sensors are coded as fixed point arithmetic. For a
factor of e.g. 0.1 in the unit the value must be divided by 10 in order to reach the real
measured value. A value of 0x8000 means that no sensor is plugged into the corres-
ponding port, or the corresponding field in the sensor is not available. The formula for
the address is (the port numbers start at zero):
0x100 + Port * 8 + Offset
In the Expert Sensor Box 7213 / 7214 the internal sensor corresponds to the
value Port = 0, and is coded Port = 1 for Sensor 2 and Port = 2 for Sensor 3.

For example, the humidity of the second port has the address: 0x100 + 1 * 8 + 1 =
0x109
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-or-
der 16-bits are starting on the even address, followed by the low-order 16-bits on the
odd address. 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.
