Measured variables of the module
The following table provides an overview of all the measured variables that data record 142
supplies. Please note that, depending on the connection type used the display of some
measured variables does not make sense and that the module deletes measured values that
are not relevant.
The measured value identification (measured value ID) is an index which references the
overview table of the measured variables in appendix (Measured variables (Page 163)).
