Cycle time (FIF-CAN2_OUT/ FIF-CAN3_OUT)
Output data transmission from FIF-CAN2_OUT and FIF-CAN3_OUT can be event or
time-controlled.
•
The transmission method is configured via code C2456/x:

Event-controlled transmission
C2456/x = 0
•
The output data is always transmitted when a value has changed in the 8-byte user data
(Lenze default setting).
Time-controlled transmission
C2456/x = 1 ... 65000
•
The output data is transmitted in the cycle time set in C2456/x (referred to the task cycle
time).
Example:
•
The CAN object is used in a 10 ms-task.
•
Factor = 5 set via C2456/2
ð
The CAN object is transmitted every fifth task cycle, i.e. every 50 ms (10 ms x 5).

Delay time (FIF-CAN2_OUT/ FIF-CAN3_OUT)
Via code C2456/4 you can configure a delay time for the transmission of the output data from
FIF-CAN2_OUT and FIF-CAN3_OUT:
