36 IQ plus 355 Installation Manual
7.1.2 Using the XE EDP Command
The XE EDP command can be used to remotely query
the IQ plus 355 for the error conditions shown on the
front panel. The XE command returns two 5-digit
numbers in the format:
xxxxx yyyyy
where
xxxxx
contains a decimal representation of any
existing error conditions as described in Table 7-2.
If more than one error condition exists, the number
returned is the sum of the values representing the error
conditions. For example, if the XE command returns
the number 1040, this value represents the sum of an
A/D reference error (1024) and an A/D calibration
checksum error (16).
The second number returned (
yyyyy
) uses the same bit
assignments as shown in Table 7-2 to indicate whether
the test for the error condition was run. For example,
the value
yyyyy
= 50815 represents the decimal
equivalent of the binary value 1100 0110 0111 1111.
Using the bit assignments in Table 7-2, this value
indicates all tests were run.
7.2 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.
7.2.1 Using the P EDP Command
The P EDP command returns the current displayed
weight value to the EDP port, along with the units
identifier. If the indicator is in an underrange or
overload condition, the weight value is replaced with
&&&&&&
(overload) or
::::::
(underrange).
7.2.2 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 uu zzz
where
wwwwww uu
is the current displayed weight and
units,
z z z
is the annunciator status value (see
Table 7-3). 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 145, the gross, standstill, and
lb annunciators are lit: 145 represents the sum of the
values for the standstill annunciator (128), gross mode
annunciator (16), and the lb/primary units annunciator
(1).
