The process image is a single unified interface to all IO data for all applications of the DACHS-Product-line from STEINHOFF
The process image is the single unique IO interface to all IO resources. It consists out of a shared memory segment splitted into an input and output sections containing an un-interpreted bit stream of IO bits. These IO sections can be is read and written by using a pair of pointers.
The process image is completely independent to the different fieldbus controllers and other IO controllers ... that means also the applications are independent of the different fieldbuses and other IO resources.
