Programming Function Blocks and Features

Table 4-72 Prompts For Storage Setup Of Trends, Alarms, Events, Diagnostics

Prompt		Range/Selections				Definition
POINT #1 -		Analog or discrete parameter				Select the data points for the trend.
POINT #12
STORAGE MODE		CONTIN, BATCH, or NONE				Continuous storage becomes active immediately upon
						initialization. Batch storage is controlled by a discrete
						parameter (see BATCH CONTROL) or by start/stop batch
						menu item. Batch data may be started and stopped several
						times in a single file until the file is full. Batch start
						increments a batch number that is stored along with the
						data. The batch number may be used for data retrieval and
						analysis using SDA data analysis software.
COPY DISPLAY						Select this to copy the following Trend 1,2, 3 or 4 Display
SETUP						data to Trend 1,2, 3 or 4 Storage data: Point #1–#12, set
						display limits, timebase (high rate) selector. Once setup is
						copied, it can be altered.
LOW RATE		Seconds: .5, 1, 2, 3, 4, 5, 6, 7, 8,				Enter data collection rate. This is how often the data points
	9, 10, 20, 30, 40, 50					are sampled.
		Minutes: 1, 2, 3, 4, 5, 10, 15, 20,
	30, 40, 50
		Hours: 1
HIGH RATE		Seconds: .5, 1, 2, 3, 4, 5, 6, 7, 8,				Enter data collection rate. This is how often the data points
	9, 10, 20, 30, 40, 50					are sampled.
		Minutes: 1, 2, 3, 4, 5, 10, 15, 20,
	30, 40, 50
		Hours: 1
ROLLOVER		ON, OFF				Select ON to continue gathering and storing data after the
						file becomes full. The new data will replace the oldest data
						on the disk as it is collected. No warning will be given.
						Select OFF to stop storage of this data type when the disk
						space for it becomes full. A “DISK FULL” message will then
						appear. Data is buffered until a new disk is inserted and
						initialized.
SET DISPLAY		OFF or number			Enter upper and lower limit values for the trend display for
LIMITS						each point. If OFF then the trend will use the programmed
						limits for each point.
HIGH RATE		SELECTOR				This discrete triggers the high storage rate when ON(1) and
SELECTORS						the low storage rate when OFF.
		CHANGE WITH KEY				This option enables/disables storage rate changes from the
						Trend display Point/Trend menu. If YES, storage Trend’s
						high rate will be used when display Trend’s alternate
						timebase is selected from the Online Point/Trend menu;
						Storage Trend’s low rate will be used when display Trend’s
						normal timebase is selected. See Table 6-2, Point/Detail
						Menu Prompts, Timebase.
EXTERNAL		OFF, discrete parameter, 0, 1				When ON(1), this discrete parameter will allow storage of
ENABLE						the data type; when off storage for the data type will stop.
						This enable is independent of the storage mode; it does not
						control batch start/stop.
