BC3150
60
Version: 2.1.0
In the delivery state (default configuration) of the BX/BCxx50, fixed addresses are allocated for all connected
Bus Terminals. The data for PROFIBUS communication start from address offset 1000
dec
. The length of the
PROFIBUS data depends on the number of configured data. The maximum is 244 bytes for the BX3100 and
128 bytes for the BC3150.

Addressing of the connected Bus Terminals
The default setting is for all the connected Bus Terminals to be assigned to the local process image.
Mapping within the Bus Terminal Controller is carried out according to the following rule:
First all the complex Bus Terminals, in the sequence they are physically inserted, followed by the digital Bus
Terminals which are filled to a byte. The default mapping of the complex Bus Terminals is:
• complete evaluation
• Intel format
• Word alignment
