and the other IO Link instructions must be Mode 2 (Grab mode).
The Mode 1: Write the ON/OFF states of the selected coils into the chosen W elements. The available W
elements in the mode 1 depend on the ID setting of that unit, refer to the table in the previous page for more
information.
The Mode 2: Grab the states of the selected W elements, and substituting the state of the selected coil. If the select
coil type is input coil I or X, coil status can’t be changed by the state of W elements.
