PM Inputs Channel Auxiliary

STATUS

The TxPDO Toggle of this channel can be read in here

Index

Indicates which parameter the “Value” is currently measuring.

Channel

Indicates the channel on which measurement is currently taking place.

Value

There are several parameters behind the Value. If the value 0 is entered in “Channel”, the following values can be read in.

  • Neutral conductor current
  • Sum of the energy (phase 1-3)
  • Frequency
  • Sum of the negative energy (phase 1-3)
  • Sum of the active power (phase 1-3)
  • Sum of the reactive power (phase 1-3)
  • Sum of the apparent power (phase 1-3)
  • Temperature at the ADC

If the value 1, 2 or 3 is entered in the channel, the following values of the respective phase 1, 2 or 3 can be read in.

  • RMS value of the harmonic of the current
  • Ratio of the harmonic to the fundamental of the current
  • RMS value of the harmonic of the voltage
  • Ratio of the harmonic to the fundamental of the voltage

If the value 11, 12 or 13 is entered in the channel, the following values of the respective phase 1, 2 or 3 can be read in.

  • the apparent power
  • the reactive power
  • the energy
  • the power factor λ
  • the frequency
  • the negative energy
  • the angle α of the respective phase to phase L1
  • the current
  • the voltage
  • the active power
  • the power factor cos φ

Switching of the individual parameters takes place using the cyclic "Index" output variables (see also tables in chapter “Operating modes and settings”).
