Connection String
With Remote Services enabled, a connection attempt will be made periodically according to the
Connection Interval setting in the Advanced Network setup tab. The Connection String is a user-
defined character string configured in the Advanced Network tab.
The connection string is also sent at the same interval once the connection is open. The external server
is responsible for closing the connection when it is done.
Remote Commands
Once the connection is open, the remote server can issue HTTP GET requests to the device for XML
files. The X-317 does not support "events" and does not send unsolicited state.xml files.
Request about.html:
GET /about.html HTTP/1.1\r\n\r\n
Set Analog Output 1 to 50:
GET /state.xml?an1State=50 HTTP/1.1\r\n\r\n
