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
From version 06.00.00 on , a so-called "blocking time" can be set in C00324/x , which defines the
shortest transmission cycle in the case of the "Asynchronous - manufacturer-specific/device profile-
specific" transmission type.
Example: Cycle time = 500 ms, blocking time = 100 ms, sporadic data change:
• With a sporadic data change < 500 ms, quickest transmission takes place every 100 ms due to
the set blocking time (event-controlled transmission). The transmission cycle timer is reset to 0
if the transmission has been activated in an event-controlled way.
• In the case of a sporadic data change > 500 ms, due to the cycle time set, transmission takes
place every 500 ms (cyclic transmission).

Tip!
The communication parameters can also be set via the following CANopen objects:
• I-1400 ... I-1402 : Communication parameters for RPDO1 ... RPDO3
• I-1800 ... I-1802 : Communication parameters for TPDO1 ... TPDO3
