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)

4


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"
