4.5 Cycle time (XCAN1_OUT ... XCAN3_OUT)
The transmission of the output data of XCAN1_OUT ... XCAN3_OUT can be carried out in an
event−controlled or time−controlled manner.
·
The configuration of the transmission mode is effected via code C2356/x:

Event−controlled transmission
C2356/x = 0
·
The transmission of the output data is always effected if a value has changed within the
8 bytes of user data (Lenze setting).
Time−controlled transmission
C2356/x = 1 ... 65000
·
The transmission of the output data is effected within the cycle time set in C2356/x (relating to
the task cycle time).
Example:
·
The CAN object is used in a 10 ms task.
·
Factor set via C2356/2 = 5
ð
The CAN object is transmitted after every fifth cycle of the task, i. e. every 50 ms (10 ms x 5).
