$AA4
Name Start-up Voltage/Current Output Configuration command
Description Stores the present output value of an analog output module
at address AA in the module’s non-volatile register. The
output value will take effect at start-up or after a brownout.
Syntax $AA4(cr)
$ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of the analog output module whose output current
is to be set.
4 is the Start-up Output Current Configuration command.
(cr) is the terminating character, carriage return (0Dh).
Response !AA(cr) if the command is 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.
(cr) is the terminating character, carriage return (0Dh).
Example command: $0A4(cr)
response: !0A(cr)
Presume the present output value of the analog output
module at address 0A is 9.4 mA. The command tells the
analog output module to store the present output value into
non-volatile memory. When the module is at start-up or
reset, its default output value will be 9.4mA. The response
of the analog output module indicates that the command
has been received.
NOTICE: An analog output module requires a maximum of 6 milli-seconds
after it received a Startup Voltage/Current Output Configuration
command to let the settings take effect . During this interval, the
module can not be addressed to perform any other actions.
