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.
