4.2 Device state machine and device statuses
The behaviour of the controller is mainly determined by the current device status within the device
state machine. Which device status is active and device status is next depends on certain control
signals (e.g. for controller inhibit and quick stop) and status parameters.
• The arrows between the device statuses mark possible status changes.
• The digits stand for the status ID (see table below).

Grey field: Pulse inhibit
 Can be reached from all statuses.
 "Warning" contradicts the definition of a device status. In fact, it is a message which is to call attention to
the device status the warning exists for.
"Warning" can occur in parallel to other device statuses.
