Arrangement of channels on the connectors :
Once the range has been programmed the standard reference channels can be
used (see above). Settings for the reference channels are described in Section
12.4.6. The best approach is to use the

A new feature is the presence of 4 device-internal channels. M9 is pro-
grammed by default as differential channel M1 – M0; this applies if there are two
sensors with the same units and same decimal point position connected at
measuring points M0 and M1. However, all four channels can be used in con-
junction with any function channels with standard reference channels Mb1 = M1
and Mb2 = M0; i.e. if you want to program a function parameter without reference
channel on a device-internal basis, the sensor must be connected to M1.
Advantage of device-internal channels :
If several sensors are being used for the same application, they do not have to
be reprogrammed and can be freely exchanged without losing their function
channel assignment. However, if the whole application operates with just one
sensor, then programming on the sensor itself makes more sense.
