RPT(n)
Purpose Read the available Q-RPT data or initiate the Q-RPT search and initialize process.
Command
Query
“RPT”
“RPT( n) ”
Classic “RPT”
“RPT( n )”
Default “RPT”
Prefix
(optional)
n Specify the position locator of the RPT about which to collect information:
‘1’ The internal, Hi RPT
‘2’ The internal, Lo, Q-RPT
‘3’ The first external RPM4, Hi Q-RPT
‘4’ The first external RPM4, Lo Q-RPT
Remarks Up to four Q-RPTs can be available for use in one PPC4 system. Two of these can be internal, and
the other two are external. These Q-RPTs must be identified and initalized before the can be used
by the PPC4. This command allows the search process to be executed (by omitting the prefix ‘n’)
and allows review of the Q-RPTs identified. Note that the search process can take up to 10
seconds to complete, and that the communications settings for the PPC4’s COM2 port and the
external RPM4 devices should be setup prior to this. If you are querying the unit for information
about a particular Q-RPT Using the prefix ‘n’), then the Q-RPT data found during the execution of
the last search is returned in the following format::
RPTType, RPTLocator, Serial#, RngGa, RngAbs, RptMode
RngLabe: RPT type label. This label identifies the RPT type and range. This is the same
label used on the PPC4 front panel screen.
RptLocator : Text field identifying the Q-RPT position in the PPC4 system.
“IH” identifies this as an internal, Hi Q-RPT
“IuH” identifies this as an internal, Hi utility sensor
“IL” identifies this as an internal, Lo Q-RPT
“X1H” identifies this as the first external RPM4, Hi Q-RPT
“X1H” identifies this as the first external RPM4, Lo Q-RPT
Serial#: The serial number of the PPC4 or RPM4 in which the Q-RPT is located.
RngGa: The Q-RPT gauge mode range in the current pressure unit.
RngAbs: The Q-RPT absolute mode range in the current pressure unit. “NONE” appears
in the field if the Q-RPT is a Gxxx, BGxxx or Axxx with absolute and negative
gauge modes OFF.
RptMode: ‘A’ if Q-RPT is Axxx and supports absolute, gauge and negative gauge
measurement modes.
‘G’ if Q-RPT is gauge Gxxx or Axxx with absolute and negative gauge modes
OFF and supports only gauge measurement mode.
‘N’ if Q-RPT is BGxxx and supports gauge and negative gauge measurement modes.
