Warning
You are reading an old version of this documentation. If you want up-to-date information, please have a look at 5.2 .Protocol specifications
Communication with EYE+ is done using a simple text-based ASCII protocol. The client sends a command, EYE+ responds with a status code followed by a message.
Important
ASCII command must be followed by a unique end of line delimiter as specified in
TCP Configuration, the default configuration is LF (i.e \n, ASCII code 0x0A).
From TCP terminal, the character is automatically sent and does not need to be specified.
EYE+ command
The command must be written in lower case with underscored separations (e.g. get_parameter). A space must be placed between the command and the parameter and between the parameter and the value. Refer to section Commands for all available commands.
without parameter or value
<command>\n
with parameter and no value
<command>␣<parameter>\n
with parameter and value
<command>␣<parameter>␣<value>\n
EYE+ response
EYE+ responds to each client’s command using a code to inform the client of the command’s status. The response always proceeds in the same way:
<response_code>␣<further information>\n
If the response holds more than one line, the number of lines is added after <response_code>.
<response_code>␣<n>␣<further information>\n
<further information>\n
...
<further information>\n

Signification |
|---|---|
200 |
The command ran successfully |
201 <n> |
The command ran successfully and contains <n> lines in the output |
4xx |
Error from the Client |
5xx |
Error from the Server (i.e. EYE+) |
