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.
