15.5 Reference percentage channel
The reference percentage channel combines various signal sources for definition of the reference
figures. The percentage scaling facilitates integration into the application, 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.
