MICROSMART AS-INTERFACE MASTER MODULE USER’S MANUAL 6-11
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.
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 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.
