Extended inputs / out-
puts
The AI3 and AI4 blocks represent anot
her 2 analog inputs which
have as yet not been assigned to any par
ticular functions. The
blocks AI5 and AI6 represent anot
her
2 additional inputs which are
only active, if t
he board SDCS-IOE1 is connected. Anot
her 7 digital
inputs DI9 … DI
15 are available with this additional hardware.
