210 Chapter 13: System Operation TempScan / MultiScan User's Manual
As you can see, two queries are available to read the HLL Registers:
U4
and
U5
. The
U4
command
requests the HLL data, maintaining the High and Low values, while the
U5
command requests then
clears the HLL data, resetting the High and Low values to the Last value.
All HLL data will be sent to the controller as dictated by the scan configuration and data format which
you have defined. You can use the
Set Query Terminator (
Q
) command to specify a response
terminator separating each channel of the HLL data, and the Set Data Format (
F
) command to specify
the output format of the HLL data.
Example 13a. Query Current HLL Registers (U4) with HLL Terminator
(1)
PRINT#1, “OUTPUT07;F0,0 Q1,1,0,0,0X”
(2)
PRINT#1, “OUTPUT07;C1-2,1 C10,1 C15,1X”
(3)
(Command lines to configure and start an acquisition.)
(4)
PRINT#1, “OUTPUT07;U4X”
(5)
PRINT#1, “ENTER07”
(6)
INPUT A$
+1450.20 S 12:23:21.700,03/24/97
+0850.20 S 12:35:09.300,03/24/97, +0950.30
(7)
PRINT#1, “ENTER07”
(8)
INPUT A$
+0450.20 S 02:00:29.500,03/24/97
+0057.60 S 10:35:00.400,03/24/97, +0250.60
(9)
PRINT#1, “ENTER07”
(10)
INPUT A$
-0045.50 S 11:03:51.700,03/24/97
-0110.10 S 12:55:09.100,03/24/97, -0050.80
(11)
PRINT#1, “ENTER07”
(12)
INPUT A$
+0150.70 S 03:39:01.200,03/24/97
-0085.20 S 05:25:17.300,03/24/97, +0010.90
The above example demonstrates how to configure and query all the HLL Registers, and how the HLL
terminator can be used to control the flow of the HLL response output. Notice that only those channels
configured – 1, 2, 10 and 15 – are returned in the response.
•
Line 1: Set the data format to Degrees Celsius (
°
C ) with HLL terminator of CR LF / EOI.
• Line 2: Configure four channels – 1, 2, 10 and 15.
•
Line 3: Provide the appropriate command lines to configure and start an acquisition.
•
Line 4: After an indiscriminate amount of time, query the current HLL settings.
•
Line 5: Get the response.
•
Line 6: The screen will show the Channel 1 scan data in the HLL Registers.
•
Line 7: Get the next response.
•
Line 8: The screen will show the Channel 2 scan data in the HLL Registers.
•
Line 9: Get the next response.
•
Line 10: The screen will show the Channel 10 scan data in the HLL Registers.
•
Line 11: Get the next response.
•
Line 12: The screen will show the Channel 15 scan data in the HLL Registers.
