PCS 400 Command Responses
All commands that terminate with a ‘?’ will respond a single time in the format stated above. At all other times
the standard output format will be used. The standard output normally starts with a space character (sp = 32
dec or 20 hex) to indicate a valid response. The space character will be replaced with an ‘E’ if an error has
occurred. (The error codes and their meanings are listed in table 4.2 on the following pages.) The user must
execute the ‘_PCS4 ERR ?’ command to clear the error. This output may be changed from the default setting
with the ‘_PCS4 OUTFORM digit’ command. The following formats are valid:
Table 4.1 – Valid Output Format
Format 1: (default or OUTFORM digit = 1)
‘sp value cr lf ‘
Where value represents the current
pressure measured in the current mode
and units with current transducer.
Format 2: (OUTFORM digit = 2)
‘sp value, unitno, function cr lf ‘
Where value represents the current
pressure measured in the current mode
and units with current transducer, unitno is
the units of measure, and function is the
current mode of operation.
Format 3: (OUTFORM digit = 3)
‘sp value, value cr lf ‘
Where the first value is the current
pressure measured in the current mode
and units with the current transducer and
the second value is the current pressure
rate of change in the current mode and the
current rate units.
Format 4: (OUTFORM digit = 4)
‘sp value, value, value cr lf ‘
Where the first value is the current
pressure measured in the current mode
and units with the current transducer. The
second value is the minimum peak
reading. And the third value is the
maximum peak reading.
Format 5: (OUTFORM digit = 5)
‘sp value, value cr lf ‘
Where the first value is the current
pressure measured in the current mode
and units with the current transducer. The
second value is the current auxiliary
(coarse) Sensor pressure in the current
engineering units.
Format 6: (OUTFORM digit = 6)
‘sp value, value, stable cr lf ‘
Where the first value is the current
pressure measured in the current mode
and units with the current transducer. The
second value is the current control point in
the current engineering units. ‘Stable’ will
b e e i t h e r t h e s t r i n g
‘ S T A B L E ’ o r
‘UNSTABLE’, depending on the current
pressure stable status.
Format 7: (OUTFORM digit = 7)
‘sp value, no barometer cr lf ‘ if
n o Ba rom etric Refer enc e
Transducer (BRT) is present;
or ‘sp value, value cr lf ‘ if a BRT
is present.
For either string the first value is the current
pressure measured in the current mode
with the current transducer. In the second
string the second value is the current
barometric pressure in the current
engineering units. This output is valid only
if a barometric reference transducer is
present. Otherwise the first example string
is returned.
