Sync application cycle
This parameter affects the influence of the sync phase position (
) with respect to
the instant of acceptance of the synchronous PDOs into the application and the instant of
transmission of the synchronous PDOs on the system bus.
For software versions below V3.0, the following applies:
The sync application cycle is fixedly set to 1000 μs.
Taking into account an internal processing time of 150 μs, the resulting PDO delay is
calculated as follows:
PDO delay = (sync cycle time - sync phase position + 150 μs) modulo 1000
From software version V3.0 onwards, the following applies:
The sync application cycle can be set in
. The set value is automatically rounded
down to integer multiples of 1000 μs.
Taking into account an internal processing time of 150 μs, the resulting PDO delay is
calculated as follows:
PDO delay = (sync cycle time - sync phase position + 150 μs) modulo
6.6.5.2
Effect of C01130 on the sync phase position
Note!
Setting a higher value for the sync application cycle (
) than for the sync
cycle time (
) results in undefined behaviour. The same applies if the sync
phase position (
) is set to a higher value than the sync cycle time
In this case, usually synchronous PDOs are not put on the system bus anymore.
Example 1:
Sync cycle time (
)
= 2000 μs
Sync phase position (
)
= 0 μs
Sync application cycle (
)
= 1000 μs
