Position ”0” (switch on the left):
central unit in central unit mode
Position ”1” (switch on the right)
central unit in sub-unit mode
Since VAMP 221 (1 and 3) serves as the central unit for I/O
units, VAMP 221 (1 and 3) must be in the central unit
operating mode.
VAMP 221 (2 and 4) must be in the sub-unit operating mode.
