GSE Scale Systems - 107
Chapter 14 Data Registers and ID's (Programmable) Technical Reference Manual
and the four alarms (for both invoking macros at
specified times or intervals) may be used for general
purpose time/date calculations if the alarm is set to off in
the setup mode. This could be used to print expiration
dates or to perform longer term rate calculations, such as
pounds per hour. Note: Short term rate calculations
(pounds per second) require more resolution on the time
scale than one second!
All time/date type parameters are stored as a numerical
value, the number of seconds elapsed since midnight on
Jan. 1, 1970. As of April 1, 1992, this value is around
702,086,400 and it increases at 86,400 seconds per day.
The alarm parameters are numbered parameter 51
through 54. If the alarms are set to be on (interval or
daily) in the setup mode, then a value may not be entered
(via a front panel entry) into that alarm. However the
alarm be manipulated using the macro math and copy
commands. If an enabled alarm is changed, then that
alarm will be invoked when the specified time occurs
(except alarm 4 which may only be set to invoke a macro
by using the "n%K" macro command).
The method of displaying these time/date type
parameters when they are selected in the weigh mode
may be set as required to be either a numeric value, a
time, a date, or a time and date by using setup parameters
P511 through P515, for recalled time, and alarms one
through four respectively. Please be aware that recalled
time is not saved during a power-down condition unless
the clock module or the database RAM module is
installed in the indicator. If neither is installed, the value
for Rtime will come up random upon power-up.
Expiration Date Example:
Copy current time to alarm 1 (named 'expiration date').
Add ten days worth of seconds to the current time to get
an expiration date ten days from now.

A Rate Example (for a decreasing weight):
to store the initial data:
Copy gross wt to var #0. Copy current time to alarm 1.
0,80%C
11,51%C
then later on:
Subtract current gross wt from previously saved gross wt.
Subtract previously saved time from current time. Copy
elapsed time, in hours, to var #1. (Note that math cannot
be performed on a mix of variable types, ie a time type
and a regular number.)
0,80%-
11,51%-
51,81%C
Divide time difference by the number of seconds per
hour. Note that division was performed after copying to
the var in order to maintain the fractional portion of an
hour! Divide weight difference by elapsed time to get
change in weight per hour.

Also, the alarms may now be selected as a parameter in a
custom transmit setup.
14.16 ID Parameter Setup
Introduction
Included within the indicator are six ID registers capable
of holding alpha-numeric data. These ID's may be used
to hold various pieces of data to be included in data
transmissions to computers or printers. Use of these ID's
may vary depending on the application. Some possible
uses include part number, bin #, employee #, shift # and
lot # to name a few. Each of the six ID's has two
associated setup parameters. The first is the maximum
number of characters that will ever need to be entered as
the ID value. The second is the name of the ID. If the
size of the ID is set to 0, then that ID is not used and the
setup parameter for its name will not appear. The name
may be 49 characters in length. However, it is
recommended that the programmed names be
abbreviated to five characters since only the first 5
characters of the name will be displayed to the operator.
If abbreviated names are used for the ID's, more
descriptive names can be programmed into the Custom
Transmit to provide more descriptive printouts. For each
enabled ID, some additional storage memory is required.
Refer to chapter 19 Memory Expansion (OPTION), for
more information on memory storage. Refer to chapter
15 Communications, for ID operation and uses in
transmissions.
