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
(p. 116).
9
Up to and including basic system version
03-24
, you could use either up to
4 × transmitters in multidrop mode or 1 × transmitters in burst mode.
10
