Local process image in delivery state
The process image of the BX controller consists of an input, output and flag area. In addition, there are unallocated
data without fixed address. They are created without specifying an address. For this type of variable, 256 kbyte (48
kbyte BCxx50) of memory are available on the BX Controller. The maximum size of a variable or structure (array) is
16 kbyte. For the allocated data 2048 bytes of input data and 2048 bytes of output data are available. The BX has 4
kbyte of memory for the allocated flag area. In the delivery state (default configuration) of the BX, 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 length is 244 bytes
(BX3100) / 128 bytes (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 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
