While B010 is ON, the data of the shift register is shifted 1 bit to the upper address direction
when X009 is changed from OFF to ON. At the same time, the state of X008 is stored in the
leading bit (B100).
The output (B011) indicates the state of the last bit (B131).
The figure below shows an operation example. (When X009 is changed from OFF to ON).
Note
When the shift input is ON, the shift operation is performed every scan. Use a transitional
contact for the shift input to detect the state changing.
For the data input and the shift input, direct linking to a connecting point is not allowed. In this
case, insert a dummy contact (always ON special device = S04F, etc.) just before the input.
