14. Each submodule has its own time base; the default value should not be changed.
The signal names in the submodules are already preset. They include the corre-
sponding characteristic value, the measuring input and the measurement interval al-
lowing it to be identified unambiguously in subsequent evaluations. The configuration
of the submodules is described in more detail in chapter 10.3.2
“EN50160 submod-
ule: Power frequency
” and following chapters. Below you will find a summary of the
key properties and the determined characteristic values of the submodules according
to EN50160. (see also chapter 10.1.1
“Overview of the modules in ibaPDA”).
