6.2 Status Messages
Two EDP commands, P and ZZ, can be used to provide
status about the indicator . These commands are
described in the following sections.
6.2.1 Using the P EDP Command
The P EDP command returns the current displayed
weight value to the EDP port. If the indicator is in an
underrange or overload condition, the weight v alue is
replaced with
&&&&&&
(overload) or
::::::
(underrange).
6.2.2 Using the ZZ EDP Command
The ZZ EDP command can be used to remotely query
which annunciators are currently displayed on the
indicator front panel. The ZZ command returns the
currently displayed weight and a decimal number
representing the LED annunciators currently lit. The
format of the returned data is:
wwwwww zzz
where
wwwwww
is the current displayed weight,
zzz
is the
annunciator status value (see Table 6-3). If more than
one annunciator is lit, the second number returned is the
sum of the values representing the active annunciators.
For example, if the annunciator status value returned on
the ZZ command is 136, the center of zero and lb
annunciators are lit: 136 represents the sum of the
values for the center of zero annunciator (128) and the
lb annunciator (8).
6.3 Continuous Output (Stream) Format
Figure 6-1 shows the continuous output format sent to the IQ plus 210 EDP or printer port when the STREAM
parameter (SERIAL menu) is set to either EDP or PRN.
