$aa6
Name
Read Channel Enable/Disable Status
Description Asks a specified module to return the Enable/Disable status
of all analog input channels
Syntax $aa6(cr)
$ is a delimiter character.
aa (range 00-FF) represents the 2-character hexadecimal
slave address of the ADAM-6000 module you want to
interrogate. (Always 01)
6 is the read channels status command.
(cr) is the terminating character, carriage return (0Dh)
Response !aamm(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 address does not exist.
! delimiter indicating a valid command was received.
? delimiter indicating the command was invalid.
aa (range 00-FF) represents the 2-character hexadecimal
slave address of an ADAM-6000 module.
mm are two hexadecimal values.
Each value is interpreted as 4 bits.
The first 4-bit value represents the status of channels 7-4,
the second 4 bits represents the status of channels 3-0.
A value of 0 means the channel is disabled, while a value of
1 means the channel is enabled.
(cr) is the terminating character, carriage return (0Dh)
Example command: $016(cr)
response: !01FF(cr)
The command asks the specific module at address 01h to
send Enable/Disable status of all analog input channels. The
analog input module responds that all its channels are
enabled (FF equals 1111 and 1111).
