Notes:
1. ∗ The AS-Interface master uses bit DO3 for addressing A/B
slaves.
2. In the above table, bits marked with X1, X2, and X3 are used
for SwitchNet I/O data.
3. X1: When pushbutton is pressed, input data is 1 (on). When
not pressed, input data is 0 (off). When output data is 1 (on),
LED is on. When output data is 0 (off), LED is off.
4. X2: The input data from 2-position selector, key selector, and
illuminated selector switches depend on the operator position
as shown below.

As shown in the table and figure, 3-position selector, key
selector, and illuminated selector switches use two communi-
cation blocks. Each communication block must have a unique
address, therefore the 3-position selectors require 2 slave
addresses.
6. Unused input bits DI3 and DI2 are 0 (off), and unused input
bits DI1 and DI0 are 1 (on). Slaves ignore unused output data
(—) sent from the master.
