X-320M™ User's Manual
Appendix D: External Server and Remote Services
required. This makes the network installation of X-320M™ very simple, and since no incoming ports
need to be opened in the router, security is not compromised. See section
2.4.3 Advanced Network
Tab
for more information.
X-320M™ can be configured to establish a connection when triggered by an event, such as a I/O state
changing. This is done by setting the Remote Service/SNMP checkbox in the
I/O
setup tabs.
When an event occurs and a connection is open, the state.xml file is sent.
If a connection is not open and Remote Services is enabled, a connection will be established by sending
the connection string. Once the connection is established, state.xml will be sent.
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.
