Key
Complete evaluation The terminal is mapped with control and status byte.
Motorola format Motorola or Intel format can be set.
Word alignment The terminal is positioned on a word boundary in the Bus Coupler.
Ch n CB Control byte for channel n (appears in the process image of the outputs).
Ch n SB Status byte for channel n (appears in the process image of the inputs).
Ch n D0 Channel n, data byte 0 (byte with the lowest value)
Ch n D1 Channel n, data byte 1 (byte with the highest value)
Res. Reserved: this byte is assigned to the process data memory, although it has no function.
