Description
Enables the display of raw (unmodified) data received from
and sent to fieldbus adapter B in parameters
150.43...150.48.
This functionality should only be used for debugging.
Display of raw data from fieldbus adapter B disabled.
Debug mode is enabled. Cyclical data update is as fast as
possible which increases the CPU load on the DC/DC
converter unit.
Debug mode is enabled but data update cycle is slow
enough to enable normal operations.
Displays the control word received from fieldbus adapter B.
For the commands assigned to each bit, see chapter
Fieldbus control through a fieldbus
Control word received from fieldbus adapter B.
Displays the raw (unmodified) reference REF1 sent by the
master (PLC) to fieldbus adapter B if debugging is enabled
by parameter 150.42 FBA B debug
This parameter is read-only.
Raw REF1 sent by master to fieldbus adapter B.
Displays the raw (unmodified) reference REF2 sent by the
master (PLC) to fieldbus adapter B if debugging is enabled
by parameter 150.42 FBA B debug
This parameter is read-only.
Raw REF2 sent by master to fieldbus adapter B.
Displays the status word sent to fieldbus adapter B. For the
commands assigned to each bit, see chapter
control through a fieldbus
Status word sent to fieldbus adapter B.
Displays raw actual value ACT1 sent to fieldbus adapter B.
Raw ACT1 sent to fieldbus adapter B.
Displays raw actual value ACT2 sent to fieldbus adapter B.
Raw ACT2 sent to fieldbus adapter B.
Selects the communication speed for the fieldbus adapter
B.
In general, lower speeds reduce CPU load. The table below
shows the read/write intervals for cyclic and acyclic data
with each parameter setting.
