Description:
This command is used to detect whether any Analog Input channels of a
specified module are under range.
Syntax:
$AAB[CHKSUM](CR)
$
Delimiter character
AA
The address of the module to be read in hexadecimal format (00 to
FF)
B
The command to detect the Analog Input channels that are under
range
Response:
Valid Command:
!AANN[CHKSUM](CR)
Invalid Command:
?AA[CHKSUM](CR)
!
Delimiter character to indicate a valid command
?
Delimiter character to indicate an invalid command
AA
The address of the responding module in hexadecimal format (00 to
FF)
NN
A two-digit hexadecimal value representing the detection results for
all Analog Input channels (00 to 3F), where bit 0 corresponds to
channel 0, bit 1 corresponds to channel 1, etc. If the bit is 0, it denotes
that the channel is normal. If the bit is 1, it denotes that the channel is
under range.
There will be no response if the command syntax is incorrect, there is a
communication error, or there is no module with the specified address.
Examples:
Command: $017C0R07
Response: !01
Sets the Type Code for Analog Input channel 0 of module 01 to 07 (+4 to
+20 mA) and the module returns a response indicating that the command
was successful.
Command: $01B
Response: !0101
Detects which Analog Input channels of module 01 are under range and
returns a response indicating that the command was successful, with a
value 01, meaning that Analog Input channel 0 is under range.
Note:
This command is only applicable when either Type Code 0x07 (+4 to +20mA)
or Type Code 0x1A (+0 to +20mA) is used.
