Step 7.1. Configure CNC Alarms

Alarms can be configured to display with messages and other information about the state of CNC's in your production facility.

CNC pre-configured alarm types

When you initially install the HMI for CNC software on your PC, three alarm types are automatically configured and added to the Alarms list.

The three pre-configured CNC alarm types are:


	Item	Description
1	CNC Alarms	Displays if the CNC is in an alarm state.
2	CNC Macro Messages	A CNC Macro Message alerts an operator to a situation that is worth noting. The message can simply be to let the operator know that something is happening, or to remind the operator that an action must be taken. Macro Messages are developed by the Machine Tool Builder and are programmed in Macro B or Macro Executor.
3	CNC Operator Messages	Alerts an operator to a situation that is worth noting. The message can simply be to let the operator know that something is happening, or to remind the operator that an action must be taken. Operator Messages are developed by the Machine Tool Builder and are programmed in CNC Ladder and are generated by setting PMC A Bits. The Alarm Class ID is always MSG, but will still show a state of ALARM in the Alarm Viewer. Once the operator acknowledges the message, the state will display as NORMAL.

By default CNC alarms use the following alarm classes.


1	Commonly used default classes.
	Class	Indicates a:
	HIGH	Serious condition that requires immediate attention.
	MED	Moderate condition that requires attention.
	LOW	Lesser condition that may require attention.
2	MSG	Pre-configured CNC alarm class for a CNC operator message.

CNC alarms can be created and configured the same as other CIMPLICITY alarms.

The following topics provide detailed descriptions of CIMPLICITY alarms.
