Table 210: Local Bus (KBus) Settings
Parameter
Explanation
Update mode
The update mode is used to configure how the local bus process
data is to be updated (refreshed).
Asynchronous In the asynchronous update mode process data
are refreshed in cycles at a definable interval.
Synchronous
*
In the synchronous update mode the process
data are synchronized with the most rapid
CODESYS task that accesses the local bus.
KBus cycle
time
The update interval for the local bus is set by the cycle time. This
setting is effective only in the asynchronous mode.
1000 µs
Minimum value 1 millisecond
10000 µs
*
Default value 10 milliseconds
50000 µs
Maximum value 50 milliseconds
KBus thread
priority
This value indicates the priority for the local bus thread. This
setting is effective only in the asynchronous mode.
This priority is equivalent to the priority of the cyclic CODESYS
tasks (see section “Cyclic Tasks”).
0
*
Highest priority
15
Lowest priority
PLC stop
behavior
Specifies the response of the local bus outputs when the PLC
application stops.
Hold last value The output states are retained.
Set to zero
*
Outputs are set to zero.
