READ TRANSDUCER TEMPERATURE (Command ‘t’)
Purpose: Returns the most recently acquired engineering-unit temperature data (in °C) for
the specified channels. Each datum returned in the response will be in the specified
high-precision data format.
Command “tppppf”
‘t’ is the command letter
‘pppp’ is the position field
‘f’ is the format field
Response “ dddd.. dddd”
‘ dddd’ are the datum fields, each with leading
space (except f =7 or 8).
Description: The 4-character hex position field (pppp) specifies a 16-bit binary bit-map, with
each set bit (1) specifying a particular channel number (16-1, left-to-right). Models
9021 and 9022 use only channels 12-1.
The 1-character format field (f) specifies the format of each data field (dddd) that
will be returned in the requested response. The first datum returned in the
response will be for the highest channel number specified. Each (non-binary)
datum will be preceded by a space character. Some formats may not be applicable
to the specific type of data being requested. Valid formats are shown in the
following table:
f converts each internal response datum value from max. char.
0 single binary float to 7-10-digit signed decimal “ [-xxx]x.xxxxxx” 13
1 single b inary floa t to 8-digit hex integer “ xxxxxxxx” 9
2 dou ble b inary floa t to 16-digit hex integer “ xxxxxxxxxxxxxxxx” 17
5 single binary float to long integer (EU*1000) then to 8-digit hex integer 9
7 single b inary floa t to single b inary floa t (big en dian: m sb first) 4
8 single binary float to single b inary floa t (little endian: lsb first) 4
