ted depends on the respective device model. For measured values such as "Neutral Cur-
rent", which are independent of the phase, the same value is returned for all phases.
DC Energy Sensors:
With the EPC 8291 / 8290 devices, the voltage and current of the individual banks and
voltage sources can be read out. The measured values of the energy sensors are re-
turned as signed 16-bit integers. The following formulas are available for the address (the
values for Bank and PowerSrc start at zero):
Bank: Bank * 2 + Offset
Power Source: PowerSrc * 2 + Offset
Examples:
"Voltage" at third bank: 2 * 2 + 0 = 0x8204
"Current" at first PowerSrc: 0 * 2 + 1 = 0x8241
Offset Sensor Field Unit
0 Voltage 0.01 V
1 Current mA
Residual Current Monitor Type B (RCMB):
Devices with a Residual Current Monitor Type B (RCMB) module separately measure the
RMS and DC fault current components of the input supply. The values are returned as
signed 16-bit integers. The following formulas are used for the address (the module num-
ber starts at zero):
Bank: ModuleNo * 8 + Offset.
Examples:
"Residual Current DC" at first module: 0 * 8 + 1 = 0x8281.
"Output DC" for second module: 1 * 8 + 3 = 0x828b
Offset Addr. Module 0 Sensor Field Unit
0 0x8280 Residual Current RMS Type B 0.1 mA
1 0x8281 Residual Current DC Type B 0.1 mA
2 0x8282 Output RMS bool
3 0x8283 Output DC bool
4 0x8284 Module State
Whether a Residual Current Monitor Type B (RCMB) module is present depends on
the particular device model.
