Command Format The format for this command is as shown below. The control point and unit num-
ber must be specified and the data code must be 00.

Response Format The responses returned for this command are shown below. The response used
depends on the smallest increment of the measured temperature (see below).
These responses assume that the header code in the command block was
transmitted and read normally, and that the end code is 00. If the end code is not
00, the measured temperature will not have been returned and the end code will
be followed by an error code (see below). If the header code in the command
block was not recognizable, a header code of IC will be returned without an end
code (see
Section 4-1-2 End Codes for the IC header code response format).
The following format is used with K or J sensors or when the temperature range
for Pt100 or JPt100 sensors is between 0
°
and 500
°
C (32
°
to 932
°
F). In either
case, the measured temperature is returned in four digits (or three numeric digits
with a sign digit) in increments of one degree. 2D
hex
is used as the negative sign.

The following format is used with Pt100 or JPt100 sensors when the tempera-
ture range is between –100.0
°
and 200.0
°
C (–148
°
to 392
°
F). In this case, the
measured temperature is returned in five digits (i.e., a sign digit plus four numer-
ic digits) in increments of one-tenth of a degree. Be sure to consider the decimal
point when reading the data. 2D
hex
is used as the negative sign.
