14 Axis bus
This function extension is available from version 02.00.00!
The 8400 TopLine controller has an integrated axis bus which is used to couple several 8400 TopLine
controllers in an axis interconnection. The main task of the axis bus is a simple cross-data exchange
from axis to axis.
Axis bus operation uses two transmission media, "data transfer axis bus" and "IO axis bus" that can
be used as follows:
• The data transfer axis bus is based on CAN physics and enables a high-performance data
transfer of master values and control signals to other 8400 TopLine controllers. This always
requires a synchronisation of the internal time base of the controllers via the IO axis bus.
• The IO axis bus is a 1-wire bus with open-collector circuitry (5 V isolated). The IO axis bus can
either be used to transfer controller errors in the interconnection ("release cord" principle) or as
a pure open-collector IO function. In the first case, the internal time base of the controllers can
be synchronised via the IO axis bus.
Max. 62 controllers can be connected to the axis bus.

Stop!
The data transfer axis bus of the 8400 TopLine controller is designed especially for
performance and simplicity. HMIs and other peripherals as well as the »Engineer« are
not supported at the axis bus.
The IO axis bus of the 8400 TopLine controller is not compatible to the state bus of the
9300/9400 device series due to different voltage levels!
