6.2.10 Mailbox Message: Start Slave
This mailbox message starts a selection of slaves that was previously removed
from the processing cycle by means of the mailbox message
FB_APPL_STOP_SLAVE.
The 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 started. The application can, however, find out about this
situation by evaluating the "Fault information" and "Message data words" of the response.
