Explanations:
1. See the specifications of each model for their range of use.
2. When ALT instruction is executed, “On” and “Off” of D will switch.
3. This instruction adopts pulse execution instructions (ATLP).
Program Example 1:
When X0 goes from Off to On, Y0 will be On. When X0 goes from Off to On for the second time, Y0 will be Off.

Program Example 2:
Using a single switch to enable and disable control. At the beginning, M0 = Off, so Y0 = On and Y1 = Off. When X10
switches between On/Off for the first time, M0 will be On, so Y1 = On and Y0 = Off. For the second time of On/Off
switching, M0 will be Off, so Y0 = On and Y1 = Off.

Program Example 3:
Generating flashing. When X10 = On, T0 will generate a pulse every 2 seconds and Y0 output will switch between On
and Off following the T0 pulses.
