Commissioning and Configuration
An external pressure sensor can be connected to the Analog Output Block (AO)
through the Foundation Fieldbus network.
Then the AO Block should be in
ACTUAL Mode Cas.
The coupled output value (AI) from the
linked pressure transmitter appears at
input CAS_IN.
In Cascade mode the measured OUT
value is passed to the transmitter and is
available to the system.
The parameter settings required for
the DI and DO blocks are given on the
following page.
