Mapping of process data
The process image of the XI/ON gateway is depicted in WORD format (16 bit). The process
data of successive modules of the same type, with process data of less than 1 word, are
grouped together until 16 bits of process data is reached. The process data is written in a new
word when:
• 16-bit input data is reached and further input modules follow
• 16-bit output data is reached and further output modules follow
• An input module, whose process data length cannot be completely incorporated in the
preceding word, follows on from another input module
• An output module, whose process data length cannot be completely incorporated in the
preceding word, follows on from another output module
