Addi-Data APCI-1710 Technical Description page 55

Functions of the board
Example:
The incremental transmitters are programmed with reference logic in the
function modules 1 to 4. The corresponding I/O function range for the
"incremental transmitter" will be copied into the therefore allocated places
of the function modules.
The following I/O range is built:
BYTES
BASE+0
BASE +59
BASE +60 bis +63
BASE+64
BASE+ 123
BASE + 124 bis + 127
BASE+128
BASE+187
BASE +188 bis +191
BASE+192
BASE+251
BASE +252 bis +255
SC: Incremental counter
All settings on the board are realized through the software (AP), through the
connector assignment or through a reprogramming of the function module
(no jumper on the board).
