The status module should be added above the command modules to be monitored. The commands above the
control module or exceeds the range are not monitored.
Each bit of the status module corresponds to the status of a command below.
Value of Bit
Status Bit Description
0
Response correct.
1
Response error or timeout.
Note:
When the GT200-DP-RS does not get the correct response of a command, it will retry to send the command.
After 3 retries and the response is still incorrect, the status bit will change to “0”.
For example:
Add a “Status (8 Commands)” module above some commands. Only the commands on the slot 4 to slot 11 will be
monitored by this module. If the value of this status module is “DE” in HEX (“11011110” in binary), the
commands on slot 4 and 9 respond error, while the commands on slot 5, 6, 7, 8, 10 and 11 respond correctly. The
status of commands on slot 1, 2 and 12 are unknown.
Exception Codes
The Exception Codes module is a 1-word module, able to give the exception codes of up to 48 commands. The
bytes of the exception codes are defined below.
