Operating manual
PROTOCOL
The computer always initiates commands with a request, the SWM always responds. If the SWM does not respond
within 500 ms, it is no longer functioning.
The SWM supports two types of request-response : 'setter' and 'getter'. The first option, setter, applies a value to the
product. The second option, getter, is used to read a value from the product.
Every command has at least one associated data item (variable). For the setter request response, the data are sent
with the command in the request. For the getter, the data are received in the response with the associated command.
The SWM returns a status update in its response to indicate that the order has been acknowledged. The setter response
always contains the command and status update. For the getter, the response contains the command and the data,
provided everything works well. Otherwise, the response will contain the order and status update.
request : command + data
response : command + status
SYNTAX
The exchanges between the computer and the SWM are done using ASCII characters.
Each request and response ends with <CR><LF> (or 0x0D0A or «\r\n»).
The command name does not contain spaces.
The command name will be followed by an equals sign (=).
In both a setter request and a getter response, the data will follow the equals sign (=). They will be separated by a semi-
colon (;). For decimal data, the decimal separator is the full stop (.). The data are represented without units.
For a getter request, a question mark (?) will follow the equals sign (=).
The status update has two values: «OK» or «KO».
Example of exchanges between the computer and the SWM:
« Process_state= run <CR><LF>
Process_state= OK <CR><LF>
«
Process_state= ? <CR><LF>
«
« Process_state= idle <CR><LF>
« Process_sta= ? <CR><LF>
« Process_sta= KO <CR><LF>
« Date= 2020 ; 13 ; 31 ; 08
« Date= KB <CR><LF>

Setter
» the computer asks to start the charging process.
» the SWM has successfully processed the command.
» requests the current process status.
» returns the requested value here IDLE (process stopped).
» poorly formatted getter request, command name does not exist.
» returns an error response.
; 53 ; 10 <CR><LF> » updates the product date with a false value (MM=13).
» returns an error status.
