4.7.6.1 General information
The X20BMx5 safety bus modules have node number switches that can be used to set permanent addresses.
Placing one of these modules at the beginning of an X20 block ensures a unique address. The addresses of
subsequent modules are automatically set in ascending order starting at this address. This simple feature greatly
increases the flexibility of applications.
Another advantage: Addresses can be set independently of which specific I/O modules are used. All that is required
are the respective bus modules. This provides logistical advantages with respect to cost and the variety of parts.
