13.5 Reference Percentage ChannelThe reference percentage channel combines various signal sources for definition ofthe reference values. The percentage scaling facilitates integration into the application,taking various process parameters into account.The Reference Percentage Source 476 determines the additive assignment of theavailable reference value sources depending on the hardware installed.Operation modeFunctionReference value source is the multifunctional1 - Abs.
