Control word received from fieldbus adapter A.
Displays the status word sent to fieldbus adapter A. For
the commands assigned to each bit, see chapter
Fieldbus control through a fieldbus
Status word sent to fieldbus adapter A.
Displays raw actual value ACT1 sent to fieldbus adapter
A.
Raw ACT1 sent to fieldbus adapter A.
Displays raw actual value ACT2 sent to fieldbus adapter
A.
Raw ACT2 sent to fieldbus adapter A.
Selects the communication speed for the fieldbus
adapter A.
In general, lower speeds reduce CPU load. The table
below shows the read/write intervals for cyclic and
acyclic data with each parameter setting.
Selection Cyclic*
Monitoring 10 ms
Normal 2 ms
Fast 500 µs
Very fast 250 µs
*Cyclic data consists of fieldbus Control and Status
words, Act1 and Act2.
**Acyclic data consists of the parameter data mapped
to parameter groups 152 FBA A data in
data out.

Fast speed.
Very fast speed.
Low speed. Optimized for PC tool communication and
monitoring usage.
Enables/disables communication between the supply
unit and fieldbus adapter B, and specifies the slot the

adapter B disabled.
Communication between supply unit and fieldbus
adapter B enabled. The adapter is in slot 1.
Communication between supply unit and fieldbus
adapter B enabled. The adapter is in slot 2.
Communication between supply unit and fieldbus
adapter B enabled. The adapter is in slot 3.
Selects how the supply unit reacts upon a fieldbus
