ƒ Cyclic data transmission with sync telegram ( 450)
(via AIF1, CAN1, CANaux1)
The sync telegram enables the controller to accept the process data from the master
(RPDOs) or send them to the master (TPDOs).
ƒ Event−controlled data transmission
(via AIF2/3, CAN2/3, CANaux2/3)
The data will be transmitted if a value changes in the corresponding output object.
ƒ Cyclic data transmission without sync telegram
(via AIF2/3, CAN2/3, CANaux2/3)
The data is transmitted in fixed times. The cycle time can be set via the following codes:
Interface Code
X1 Automation interface (AIF) C2356
X4 ECSxS/P/M: MotionBus (CAN)
ECSxA/E: System bus (CAN)
C0356
X14 System bus (CAN)
l Interface is not available for ECSxE.
C2456
– Setting of cycle time > 0: data transmission with fixed cycle time
– Setting of cycle time = 0: event−controlled data transmission
