The communication parameters such as the transmission mode and cycle time can be set freely for

every PDO and independently of the settings of other PDOs:

Blocking time
In

C00324/x

, an "inhibit time" can be set that defines the shortest transmission cycle for the "asyn-

chronous - manufacturer-specific/device-profile specific" transmission type.
Example: Cycle time = 500 ms, blocking time = 100 ms, sporadic data change:

• In case of a sporadic data change < 500 ms, fastest transmission is every 100 ms (event-cont-

rolled transmission). The transmission cycle timer is reset to 0 if the transmission has been trig-

gered in an event-controlled manner.

• In case of a sporadic data change > 500 ms, fastest transmission is every 500 ms due to the set

blocking time (cyclic transmission).

Tip!
The setting can also be carried out via the following CANopen objects:
