$AA8
Name
Current Readback command
Description
The addressed analog output module is instructed to
measure the current flowing through its current/voltage
loop and return the measured data in the module’s
configured data format. The value returned may be a rough
estimate of the real value.
Syntax
$AA8(cr)
$
is a delimiter character.
AA
(range 00-FF) represents the 2-character hexadecimal
address of the analog output module that you want to
retrieve the data from. The data are current/voltage
loop.
8
is the Current feedback command.
(cr)
is the terminating character, carriage return (0Dh).
Response
!AA(data)(cr)
if the command was valid.
?AA(cr)
if an invalid command was issued.
There is no response if the module detects a syntax or
communication error, or even if the specified address does
not exist.
!
delimiter character indicates that a valid command was
received.
?
delimiter character indicates that the command was
invalid.
AA
(range 00-FF) represents the 2-character hexadecimal
address of the analog output module.
(data)
is the value returned by the analog output module.
(cr)
is the terminating character, carriage return (0Dh).
Example
command:
$0A8(cr)
response:
!0A18.773(cr)
The command tells the analog output module at address
0Ah to measure its current loop and return the measured
value.
The analog output module returns the value 18.773 mA.
