Read measured values
InputMode
The PZDInxx inputs are assigned to the ModeInxx parameter inputs. These determine
whether the measured values are read acyclically from data records (ModeInxx = 0) or
Cyclically updated (ModeInxx <> 0) through Process image wiring.

If the active power or the apparent power should be read in cyclically, two consecutive inputs have
to be configured with
ModeInxx = 20 and ModeInxx = 21 respectively because the active power
and apparent power occupy a double word in SIMOCODE pro.
