adapter B to the master (PLC) if debugging is enabled by
parameter 50.42 FBA B debug
This parameter is read-only.
Status word sent by fieldbus adapter B to master.
Displays raw (unmodified) actual value ACT1 sent by fieldbus
adapter B to the master (PLC) if debugging is enabled by
parameter 50.42 FBA B debug
This parameter is read-only.

Selects the communication time levels.
In general, lower time levels of read/write services reduce
CPU load. The table below shows the time levels of the
read/write services for cyclic high and cyclic low data with
each parameter setting.

* Cyclic high data consists of fieldbus Status word, Act1 and
Act2.
** Cyclic low data consists of the parameter data mapped to
parameter groups 55 FBA B data in
and acyclic data.
Control word, Ref1 and Ref2 are handled as interrupts
generated on receipt of cyclic high messages.
