10.2 Status Messages; Using The Xe Edp Command - Rice Lake IQ plus 710 Installation Manual

10.1.2

Using the XE EDP Command

The XE EDP command can be used to remotely query
the IQ plus 710 for the error conditions shown on the
front panel. The XE command returns a decimal
number representing any existing error conditions.
If more than one error condition exists, the number
returned is the sum of the values representing the error
conditions (see Table 10-2). 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 P EDP command returns whatever is
currently shown in the indicator's primary
display area.
• The ZZ EDP command returns whatever is
currently shown in both the primary and
secondary displays. Depending on the type of
device used to receive data from the indicator,
the standstill and center of zero symbols may
be shown as spaces or as special characters.
The ZZ command returns information in the
following format:

• is the information shown on the
PPPPPPP
