Hints on parameterization
Branch <device> – Basic System – I/O boards –
Board <x>: ExMFE5
Set the following value:
•
channel P1+ P1−: type HART channel
With this, the operating mode of the channel is set correctly for
connecting the HART transmitters.
If you are using the basic system version 03-24 and earlier, refer
to FAQ
11.2 Limitations for multidrop and burst mode up to basic
system version ≤ 03-24
Up to and including basic system version 03-24, you could use either up to
9
4 × transmitters in multidrop mode or 1 × transmitters in burst mode.
10
