FB_PMA_Scaling_EL3773
The function block FB_PMA_Scaling_EL3773 is a special version of the function block FB_PMA_Scaling. It is used for scaling raw values provided by the EL3773 EtherCAT Terminal. The raw values can be scaled individually or as an array, for example as oversampling values. In addition, it is possible to use single-phase and three-phase input signals.
Syntax
Definition:
FUNCTION BLOCK FB_PMA_Scaling_EL3773
VAR_INPUT

Inputs
The input parameters of this function block represent initialization parameters and have to be assigned during the declaration of the function block instance (alternatively: Init method). They may only be assigned once. A change at runtime is possible by calling the Init method again.
