12.3.10 Function channels

At the end of the table of measuring ranges and units (see above) under the
sub-heading Function channels there is a group for representing function pa-
rameters in measured value processing or calculated results from linking cer-
tain measured values on measuring channels (see Manual 6.3.4). Reference to
the actual measuring channels is provided by one or two reference channels.
For all function channels the default reference channels Mb1 and Mb2 are
available on the appropriate connector; these channels do not need program-
ming.
