The PN/CAN LINK is ready for reset.
A reset acknowledgment bit is used
in the data that are transmitted
cyclically from the PN/CAN LINK to
the S7 controller to provide
feedback to the S7 controller
regarding the reset of the CANopen
side. As soon as the command for
resetting the CANopen side has
been received, this bit is set to "1".
The S7 controller must then set the
reset bit to "0". When the reset of
the CANopen side is complete, the
PN/CAN sets the reset
acknowledgment bit to "0".

The PN/CAN LINK is currently
performing or has performed a reset
but the reset bit of the S7 controller is
