9.1.3 Communication time
The communication time is the time between the start of a request and the arrival of the correspon-
ding response.
 Tip!
The communication times in the CAN network depend on:
• the processing time in the device
• the telegram runtime (baud rate/telegram length)
• the bus load (especially if the bus is charged with PDOs and SDOs at a low baud rate)
Processing time in the 8400 controller
No dependencies exist between parameter data and process data.
• Parameter data: approx. 5 ms (typical value)
• For parameters concerning the motor control (e.g. C011), the processing time may be longer
(up to 30 ms).
• Process data: 1 ms
