13.5 Reference Percentage Channel
The reference percentage channel combines various signal sources for definition of
the reference values. The percentage scaling facilitates integration into the applica-
tion, taking various process parameters into account.
The
Reference Percentage Source 476 determines the additive assignment of the
available reference value sources depending on the hardware installed.
