the use of a custom transmit.
For instance, previously the time/date could only be
copied by a macro with "11%C". This would cause the
numeric value that represents the current time/date to be
put into the entry buffer. Now however, if only the date
were required, the command 64;11F%C could be issued.
This would put the time/date in format 64 (date only),
such as 1/7/94, into the entry buffer. This value could
then be easily copied into an ID or transmitted.
nU,m%C Unrounded Gross and Net
Occasionaly it has been desirable to allow a macro access
to the unrounded value of the gross or net weights. This
is now possible through a slight variation of the %C and
math commands. Appending a 'U' or 'u' to the gross or
net parameter number within a "%C" command or math
command causes the unrounded value to be used. For
instance:
n = 0 or 1, parameters gross or net respectively.
m = any other numerical register that will not round or
truncate.
0u,88%C Copies the unrounded gross weight to var #8.
1U,83%* Multiplies the unrounded net weight by var
#3, storing the result in var #3.
This capability can be useful in applications where
calculations are being done based upon weight and
additional precision is required beyond what is being
shown on the display.
Note that this feature is only intended for use in copying
from the gross or net weight, not to the gross or net
weight. Copying to these parameters is not common
since the values of the gross and net are constantly being
recalculated and any values copied to these parameters
would be overwritten by the next weight conversion
process.
%d Display On/Off
The display may be turned off with a macro command,
"%d", or turned back on with "0%d". Turning the
display off provides about a 13% improvement in the
execution time of the instrument. This may be helpful in
some macro situations. It will also decrease power
consumption of the instrument somewhat.
This command may be useful in blanking the display
during macro operations.
An alarm can be programmed to invoke a macro on an
interval basis and check a setpoint active on motion. If
no motion exists, the display in blanked.
32%F
%d
%E
On the other hand, a setpoint can be activated on motion
or above a threshold value and invoke a macro to turn the
display on. Add 0%d to the macro invoked by this
setpoint.
This example might increase battery life in some
instances.
n%D Deactivate setpoint n
This command can be used to cause any setpoint to
become de-activated, regardless of the conditions which
have been setup to cause it to de-activate. The 'n' must be
a number between 1 and 32 which specifies the exact
setpoint number to de-activate.
One common use for this would be to provide an
operator with a prompt and then after the response is
given by the operator the setpoint would become
activated.
Example: (M574 has no hardware outputs,
contact GSE for external setpoint
information.)
STOP LINE?%W Prompt operator and wait for
any key.
1%D De-activate setpoint #1.
For this example the setpoint could be set for 'de-activate
never' which would prevent the setpoint from being de-
activated except by this command.
Note that if the conditions for the setpoint to become
active were present when the "1%D" command was
executed then the setpoint output signal would remain
de-active only until the next weight conversion process
was completed.
An interesting and sometimes useful feature of this
command is that setpoints which are not enabled may
also be activated and de-activated. Thus if a setpoint is
only to change state based on events that occur during a
macro, the setpoint would not require any setup and
