Support Static Query		Check this option if you want the object displays the alarm records filtered by predefined conditions. With static query, any change of query conditions at runtime will not be applied.
Query Trigger Bit		Specifies the bit that will trigger the query operation at runtime. The HMI reads the Query Parameter Block and refreshes the object according to the current query conditions whenever the Query Trigger Bit changes from Off to On. Click to enter the bit address. Click to enter the bit tag. Available only when the Support Dynamic Query option is selected.
Query Parameter Block		Specifies the location that stores the query parameters. Click to enter an address for this field. Click to select a tag for this field. The following table shows the data arrangement of the parameter block.
		0	The query flags.
			Bit		Operation
			0		Query the alarm records according to the specified alarm number when the bit is on. The alarm number is specified in word 1 of the Query Parameter Block.
			1		Query the alarm records that occurred within the specified duration when the bit is on. The date range is specified in word 2-7 of the Query Parameter Block. The time range is specified in word 8-13 of the Query Parameter Block.
			2		Query the alarm records according to the specified alarm status when the bit is on. The alarm status is specified in word 14 of the Query Parameter Block.
			3		Query the alarm records according to the specified alarm block when the bit is on. The alarm block is specified in word 15 of the Query Parameter Block.
			4		Query the alarm records according to the specified alarm level when the bit is on. The alarm level is specified in word 16 of the Query Parameter Block.
			5		Query the alarm records according to the specified alarm ID when the bit is on. The alarm ID is specified in word 17-20 of the Query Parameter Block.

Block Size (Words)		The size in word of query parameter block.
Query Items	Date Range	Check this option if you want the object to display the alarms that occur in the specified date range.
	Time Range	Check this option if you want the object to display the alarms that occur in the specified time range. Available only when the Date Range is checked.
	Alarm Number	Check this option if you want the object to display the alarms with the specified alarm number.
	Alarm Status	Check this option if you want the object to display the alarms with the specified alarm status.

	Alarm Level	Check this option if you want the object to display the alarms with the specified alarm level.
	Alarm ID	Check this option if you want the object to display the alarms with the specified alarm ID.
	Customized items to be processed by the query processing macro	Check this option if you want to set query conditions in query processing macro. Note: A query processing macro must use QRET command to report if the currently processed record is qualified for the current query and terminate itself. Only qualified records are displayed according to the query conditions. The following is an example that the object will show the active alarms only.
	Current Data Buffer	Specifies the variable representing the data buffer for query processing macro to save the current alarm. Click to enter an address for this field. Click to select a tag for this field. The following table shows the data arrangement of the buffer.
