HTTP Server

The HTTP Server tab is used to configure the HTTP Server feature of a node.

The HTTP Server is used to support the HTTP Page Listener trigger event type.

On Asset Gateways, the HTTP Server is used to support the Asset Gateway: Web Interface.

The HTTP Server is not supported on the following product:

  • Mitsubishi MESInterface IT

Configuring the HTTP server

The tab's parameters are:

Parameter Description
Status The HTTP Server Status is either STARTED or STOPPED.
Acquired License Count The number of HTTP API Server licenses currently in use.

Licenses for four concurrent sessions are available with the base runtime installation. Licenses for concurrent sessions beyond the provided four licenses must be acquired through a HTTP API Server license. If there are any question regarding the availability of licenses, contact your support representative.

Each user session to the HTTP Server acquires a license. The license remains in use as long as the session remains active. When the session ends, the license is no longer in use and is available for another user session.

There are three system variables associated with the HTTP API Server licensing:

  • http.license.in_use - The current number of licenses in use. This is the same value displayed in the Acquired License Count parameter.
  • http.license.rejected - The number of license requests that have been rejected.
  • http.license.total - The total number of licenses available. This includes the four system provided licenses and any added (and valid) HTTP API Server licenses.
Address The address and port for HTTP access. The default is 0.0.0.0:8080.
A value of 0.0.0.0 for the IP address indicates that the HTTP Server should listen using the IP addresses for  all enabled networks adapters in the node.
If a single specific IP address is used, the HTTP Server will only listen using that IP address.
The port value of 8080 is used to avoid conflict with any other HTTP servers executing on the node.
SSL Address The address and port for HTTPS access. The default is 0.0.0.0:8443
A value of 0.0.0.0 for the IP address indicates that the HTTP Server should listen using the IP addresses for  all enabled networks adapters in the node.
If a single specific IP address is used, the HTTP Server will only listen using that IP address.
The port value of 8443 is used to avoid conflict with any other HTTP servers executing on the node.
User The user name (defined using the node's Administration -> Security function) to use when connecting to the HTTP Server.
Password The password for the user name to use when connecting to the HTTP Server.

The Save button is used to save any change to the parameters.

The Start Server and Stop Server buttons control the HTTP Server's status.
