READ TRANSDUCER TEMPERATURE (Command 't')
Purpose:
Returns the most recently acquired engineering-unit temperature data (in ºC) for
the specified channels. Each datum returned in the response will be in the
specified high-precision data format.
Command
“t[p]ppppf”
‘t’ is the command letter
‘[p]pppp’ is the position field
‘f’ is the format field
Response
“ dddd[ dddd]...”
‘ dddd’ are datum fields, each with a leading space (except f =7).
Description:
The 4 or 5 character hex position field ([p]pppp) specifies a 16 or 20 bit
binary bit-map, with each bit set to 1 to specify a particular channel
number (S & P external rack channels, plus internal channels 16-1, left-
to-right).
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 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 binary float
to
8-digit hex integer “ xxxxxxxx”
9
2
double binary float 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 binary float
to
single binary float (big endian: msb first)
4
8
single binary float
to
single binary float (little endian: lsb first)

Example:
●
Send TCP/IP command to 9816 module (via its connected socket) that returns decimal
temperature data for channels 1, 5, 9, and 13:
“t11110”
Response contains data (in C) for channels 13, 9, 5, and 1 (left to right):
"21.234000 20.989500 21.005390 20.899602"
