4.4.8 Mailbox Message: Stop Slave
This mailbox message stops a selection of slaves from the processing cycle.
This message is allowed in all Operation modes (STOP, CLEAR and
OPERATE).
Note: The message will be accepted even if one or several slaves are not part of the configuration
and can therefore obviously not be stopped. However, the application can find out about this
situation by evaluating the "Fault information" and "Message data words" of the response.
