250 m
Hints on parameterization
Branch
<device> – Basic System – I/O boards –
Board <x>: MFE7
Set the following values:
•
channel
A1+ A1−
or
A2+ A2−
the type
HART channel
•
parameter
Power supply
the value
Off
With this, the operating mode of the channel is set correctly for
connecting the HART transmitter.
The following HART modes are possible:
•
Multidrop mode (max. 4 transmitters)
Note that the HART device cannot be operated using the
HART address
zero (
0
).
•
Burst mode (max. 1 transmitter)
Set the burst mode, as you parameterize the
HART address
zero (
0
) for the HART device.
