6-byte process image
The 6-byte process image only consists of the parameter data block. In contrast to the other process images, it does not support direct access to the process data of the AS-i slaves. The process data access must take place via the AS-i parameters 0x80 to 0x87 (digital slaves) or 0x204 to 0x27F (analog slaves).
