Refer to Process Input Data of each Hub in 6-1 Process Data on page 6-2 for details on the each bit.

How the Reset Operation Works
If the cause of the error is removed, executing reset turns OFF the error detection hold bits.

Resetting the Bits
Write 01 hex: reset in the following service data through message communications from the Con-
troller to the IO-Link device.
Doing so turns OFF All Detection Hold Bits Reset.
Turning OFF All Detection Hold Bits Reset turns OFF all error detection hold bits.
