8400 StateLine C | Reference manual
System bus "CAN on board"
General information
430 L Firmware ≤ 11.00 - DMS 8.0 EN - 10/2011
10.1.3 Communication time
The communication time is the time between the start of a request and the arrival of the
corresponding 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. C00011), the processing time may
be longer (up to 30 ms).
Process data: 1 ms
