Mul File Specification - Alarms

Specification of the Alarms.mul file

Alarms, Alarms.mul, specification

Function

The alarms file allows the engineer to specialise the alarm messages for each individual machine. The basic premise is that most alarms are generated when

1. an alarm input is activated, such as overload relay, air pressure switch
2. an input is not detected within a specified amount of time, depending on an output state (timeouts on cylinder movements)

An alarm will be triggered if the input matches the "Input Alarm Trigger State" and the output matches the "Output Alarm Trigger State" for a duration of the "Alarm Timeout".

There is also an option for the "Severity" of the alarm:

Severity	Action	Description	Notes
1	Log	Write note to diagnostics file and take no action	...For programmer use only
2	Display	Report to front end, but take no action	...For programmer use only
3	Cycle Stop	Report to front end Pause machine Wait for start or abort
4	Abort	Report to front end Stop machine Force Abort and restart

Field Format

No	Name	Format	Notes
1	Alarm Ref No	3N	Reference or code number that appears on the front end screen (easier and more accurate to report a code number than a text description)
2	Input Ref	15A	IO Code name from IODef file
3	Input Alarm Trigger State	2N	State that will trigger an alarm 0 - Input inactive -1 - Input Active
4	Output Ref	15A	IO Code name from IODef file
5	Output Alarm Trigger State	BOOL	State that will trigger an alarm 0 - Input inactive -1 - Input Active
6	Timeout	3N	Time in 10ths of a second that trigger states are triggered before the alarm is triggered
7	Action / Severity
8	Display Message
9	Enabled
