Hot configuration

Hot configuration allows you to configure some parameters in the Communication Driver while it is running.

If you change the value of a parameter and it immediately takes effect while the Communication Driver is running, the parameter is hot-configurable.

The following parameters and features are hot-configurable:

• Global parameters on the Configuration node.

• Adding, deleting, or modifying a device in a channel. (Modifying a device does not affect other devices except for the children of the modified device.)

• Adding, deleting, or modifying a device group, in the Device Groups tab on a device node.

• Adding, deleting, or modifying an item reference, in the Device Items tab on a device node.

There is no support for hot configuration of server-specific parameters. If you configure server-specific parameters while the Communication Driver is running, a warning message is displayed to restart the Communication Driver for the changes to take effect.

See the sections about the specific parameters for limitations or constraints.

Note: If a configuration change is made when the Communication Driver is running, it is highly recommended to perform a reset on the corresponding hierarchy.
