I# - Digital Input Stamping
TYPE System
EXECUTION
Deferred
SYNTAX I#state Specify whether or not digital input stamping will be enabled. state may
have either of the following values: The default of 0 , which disables digital
input stamping, or 1 to enable digital stamping.
DESCRIPTION
The Digital Input Stamping ( I# ) command, when enabled, will append the digital input state to the end of each
scan as it occurs in real time.
The digital input state consists of 8 bits ( I8 through I1 ). Each bit has an assigned binary value of “1” or “0,”
where “1” indicates digital input “on” and “0” indicates digital input “off.”
In binary mode, 2 bytes will be appended as follows: Byte 2: 00h, I8
-
I1
In ASCII mode, 8 bytes will be appended as follows: DXXXD000
Where D = User Terminator, and XXX = the decimal equivalent of I8
-
I1 .
Note: If Alarm Stamping ( A# ) is also enabled, the Digital Input Stamp ( I# ) will be appended after the
Alarm Stamp.
EXAMPLES
Without Digital Input Stamping (default):
PRINT#1, ‘I#0X”
‘ Disable digital input stamp
‘ Configure and start an acquisition
PRINT#1, “R1X”
‘
Request the next scan in the buffer
LINE INPUT#1, A$ ‘
....+0234.20-0019.40+0001.40+0023.60
With Digital Input Stamping:
PRINT#1, “I#1X”
‘ Enable digital input stamping
‘ Configure and start an acquisition
PRINT#1, “R1X”
‘ Request the next scan in the buffer
LINE INPUT #1, A$
