Mapping the Bus Terminals

The precise assignment of the byte-oriented Bus Terminals may be found in the configuration guide for the
particular bus terminal. This documentation is available on the Beckhoff Products & Solutions CD or on the
Internet under http://www.beckhoff.de.

Local process image

All connected bus terminals are assigned in the default setting to the local process image of the BC/BX.
Mapping within the Bus Terminal Controller is carried out according to the following rule:
First come all the complex Bus Terminals, in whatever sequence they are physically inserted, followed by the
digital Bus Terminals which are padded to a whole byte.
The default mapping of the complex Bus Terminals is:
• complete evaluation
• Intel format
• Word alignment
