Description
Displays the control word received from fieldbus adapter A.
For the commands assigned to each bit, see chapter
Fieldbus control through a fieldbus
Control word received from fieldbus adapter A.
Displays raw (unmodified) reference REF1 sent by the
master (PLC) to fieldbus adapter A if debugging is enabled
by parameter 150.12 FBA A debug
This parameter is read-only.
Raw REF1 sent by master to fieldbus adapter A.
Displays raw (unmodified) reference REF2 sent by the
master (PLC) to fieldbus adapter A if debugging is enabled
by parameter 150.12 FBA A debug
This parameter is read-only.
Raw REF2 sent by master to fieldbus adapter A.
Displays the status word sent to fieldbus adapter A. For the
commands assigned to each bit, see chapter
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

*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
out.
