Data Fields
Status: The Status character is a 1 byte field that indicates
the operational status of the counter during the last
sample period. This character is the string
representation of an ASCII code. For example, the
Status character in Figure A-1 is a "$", which is
ASCII 36 or, in binary, 00100100. Table A-9
translates the Status characters into fault types. A
sample interval with no faults is an ASCII 32 or
00100000, which shows in the Status character as a
space.
Binary Bit 5 is always a one, Bit 7 is always a zero.
Note:
Spaces are used
as field separators.
Date: The Date is carried in characters 3 through 8,
formatted as MMDDYY.
Time: Time information is in characters 10 through 15.
Time is expressed in 24-hour format as HHMMSS.
Sample Interval: Sample Interval information is found in characters
17 through 20. The Interval is in the form MMSS.
When the Interval is controlled by the computer
through the
c or uc command, the Interval
characters will be all zeroes. When the Interval is
controlled by the instrument (
d or ud command),
