2.3.1.3 Power-on/off of the PANEL i for AUTOMOTIVE with I/O Link
The PANEL i for AUTOMOTIVE with I/O Link operates as a slave I/O
device of I/O Link.
For this reason, the power to the PANEL i must be turned on or off at the
same time when the power to the CNC control unit or cell controller
having the I/O Link master functions is turned on or off. (For the
allowable time difference, refer to the relevant CNC connection manual.
An example for the Series 16i is shown below.)
If this power-on/off sequence is not followed, an error may occur in the
CNC control unit or cell controller or the I/O Link adapter built into the
PANEL i may not normally be connected to I/O Link.
