10.3.2Start identification, axis monitoring and automatic state change chains

Start identification

Identify whether a restart is present.

If yes, then

•Activate the monitoring of the parameterization of the technology objects as well as auto-parameterization.

•Control the state machines in the “manual” state via the state sequence

–Error

(if activated, the monitoring and auto-parameterization are realized in the error state)

–Disable

–Manual

From any state.

If no, then

•Transfer the selected operating state with a positive edge at the execute input

•Reset all block outputs with a negative signal edge at the execute input

Axis monitoring functions

The flying saw axis has an error, the "FlyingSaw FB“ is forced into the error state.

However, the monitoring function is only active after the technology objects have been successfully completed.

Automatic state change sequences

The following automatic state change sequences have been implemented:

•From the “error” state into the “starting position” state. “Error“ Æ “Disable” Æ “Starting position”

•From the “error” state into the “automatic” state. “Error“ Æ “Disable” Æ “Starting position” Æ “Automatic”

•From the “error” state into the “manual” state. “Error“ Æ “Disable” Æ “Manual”

•From the “starting position” state into the “manual” state. “Starting position” Æ “Disable” Æ “Manual”

•From the “automatic” state into the “manual” state. “Automatic” Æ “Error” Æ “Disable” Æ “Manual”
