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
‘5’ The second external RPM4, Hi Q-RPT
‘6’ The second external RPM4, Lo Q-RPT
Remarks Up to six Q-RPTs can be available for use in one PPC3 system. Two of these can be internal,
and the other four are external. These Q-RPTs must be identified and initalized before the can
be used by the PPC3. 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 PPC3’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 PPC3 front panel screen.
RptLocator: Text field identifying the Q-RPT position in the PPC3 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
“X2H” identifies this as the second external RPM4, Hi Q-RPT
“X2H” identifies this as the second external RPM4, Lo Q-RPT
Serial#: The serial number of the PPC3 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.
