SwitchNet Data I/O Port
SwitchNet control units can be used as slaves in the AS-Interface network and are available in ø16mm L6 series and
ø22mm HW series. Input signals to the
MicroSmart AS-Interface master module are read to internal relays allocated to
each input point designated by a slave number and a DI number. Similarly, output signals from the MicroSmart AS-Inter-
face master module are written to internal relays allocated to each output point designated by a slave number and a DO
number. When programming a ladder diagram for the
MicroSmart , use internal relays allocated to input signals and output
signals of SwitchNet control units.
L6 series and HW series SwitchNet control units have slightly different digital I/O data allocations.
L6 Series Digital I/O Data Allocation
Input data is sent from slaves to the AS-Interface master. Output data is sent from the AS-Interface master to slaves.

1.
∗
The AS-Inter face 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 and 2-position lever switches
depend on the operator position as shown below.
5. X3: The input data from 3-position selector, key selector, and
illuminated selector switches and 3-position lever switches
depend on the operator position as shown below.
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.
