BECKHOFF AX2500 - Manual (Page 86)

9.4 Multi-axis systems
All the axes in a system can be parameterized through the RS232 interface in the master.
To do this, there is an internal connection between the master and the axis modules. The
PC cable only has to be connected to the master.
The internal address assignment is carried out automatically, so that it is only necessary
to set up the basic station address for the master.
9.4.1 Station Address
Adjust the address of the master with the setup software. The addresses of the axis mod-
ules are then assigned automatically.
After changing the station address it is necessary to turn off the 24 V auxiliary
supply, and then turn it on again.
Starting at the master, descending addresses are assigned automatically to the axis mod-
ules. The following table shows an example with one master and three axis modules
according to the graphics above:
Axis Address Remark
Master 10 Master address, set by user
Axis module 3 9
assigned automatically Axis module 2 8
Axis module 1 7
The highest permitted master address is 128. When choosing the master address,
please consider that at least address 1 will be assigned to the last (leftmost) axis
module.
In CAN and PROFIBUS field bus systems the automatically assigned addresses
must not match the address of other nodes.
