Server Menu

The Server pull-down menu is shown below. Descriptions of the Server options follow.

Run

NOTE: The Server automatically goes into Run mode when the application is started. Run mode and Configure mode are mutually exclusive; i.e., selecting Run disables the Configure menu until Stop is selected. Similarly, when the Server is Stopped, the View menu is disabled until Run is again selected.

Run puts the PMCS DDE Server into action, ready to answer requests for data from client applications. Clicking this menu item brings the server on-line with the available configuration.

You must configure the server before it can be run or a client requests data from it. Configuration is a one-time process (changes may be made later). The configuration information is saved to disk and loaded each time the Server is run. You cannot configure the Server while it is running. Choose Run to disable the Configure menu item and enable the View menu. This action also enables the Suspend Protocol menu item.

The Server waits for DDE clients to become active. When a client requests data, the PMCS DDE Server answers the request by retrieving this data from the appropriate devices.

Stop

Stop sets the PMCS DDE Server off-line, preventing it from requesting any data from devices. Before you can stop the server, however, DDE links with client applications must be broken (this may require closing the client application).

After the PMCS DDE Server is off-line, you can make configuration changes.

If, after entering Stop mode, you do not enter Configure mode, a DDE request from a client automatically returns the Server to Run mode.
