Settings Precedence

When a Plant SCADA Access Anywhere client starts, it reads configuration information from a variety of sources. If two or more sources contain different values for the same setting, the value that Plant SCADA Access Anywhere will use is determined by the following precedence order:

Highest precedence to Lowest precedence

• URL parameters

• Cookies

• Saved settings from previous session

• config.js

For example, if the gateway_address is specified to be "server1" in config.js but "server2" in a cookie (EAN_ gateway_address), then the value "server2" will be used.

If the setting override Saved is set to true in config.js, then any settings predefined in the config.js file will override previously used settings, and the precedence order will change slightly:

Highest Precedence to Lowest Precedence

• URL parameters

• Cookies

• Saved settings from previous session

• config.js

  Note: These settings become effective only after the user starts a new session. In some cases, the local browser needs to be closed and reopened before changes become effective. The local browser cache may also need to be cleared.
