$aaSi3
Name
CJC Status Command (ADAM-5018
only)
Description
Returns the value of the CJC (Cold Junction Com-
pensation) sensor for a specified analog input mod-
ule
Syntax $aaSi3(cr)
$
is a delimiter character.
aa
(range 00-FF) represents the 2-character hexadeci-
mal address of the ADAM-5000/TCP system.
Si
identifies the I/O slot which contains the CJC Sta-
tus you wish to retrieve.
3
is CJC Status command.
(cr)
is the terminating character, carriage return (0Dh)
Response >(data)(cr)
if the command is valid.
?aa(cr)
if an invalid operation was entered. There is
no response if the module detects a syntax error or
communication error or if the specified ad- dress
does not exist.
>
delimiter character indicating a valid command was
received.
?
delimiter character indicating the command was in-
valid.
aa
(range 00-FF) represents the 2-character hexadeci-
mal address of an ADAM-5000/TCP system.
(data)
is the value that is retrieved by the module by
reading its CJC sensor. The data format, in degrees
Celsius, consists of a “+” or “-” sign followed by five
decimal digits and a fixed decimal point. The resolu-
tion of the data is 0.1°C.
(cr)
is the terminating character, carriage return (0Dh)
Example
command:
$01S13(cr)
response:
>+0136.8(cr)
The command requests the
analog input module in slot 1 of the ADAM-
5000/TCP system at address 01h to read its CJC
sensor and return the data. The ana- log input
module responds with 36.8°C.
