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 under range or
overload condition, the weight value is replaced with
&&&&&&
(overload) or
::::::
(under range).
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).
