Key

Complete evaluation: Additionally to the process data the control and status bytes are showed in the address area
Motorola format: Motorola or Intel format can be set.
Word alignment: in order that the address area of each channel starts always on a word boundary, dummy bytes are added to the process image

SB n: Status Byte for channel n (appears in the process image of the inputs)
CB n: Control Byte for channel n (appears in the process image of the outputs)

Ch n D0: channel n, data byte 0 (lowest significant byte)
Ch n D1: channel n, data byte 1
Ch n D2: channel n, data byte 2
Ch n D3: channel n, data byte 3 (most significant byte)

reserved: Although this byte occupies space in the process data memory, it has no function
"-": This byte is not used or occupied by the Fieldbus Box.
