Menu Bar

The menu bar organizes the remaining tools in the LEC Configuration Manager and provides quick access to some of the most used features of the software. It also contains a group of buttons used to create connectors between nodes and an easy-to-find button that can be used to stop or start the LEC server.

Again, in addition to providing access to the File, Edit, View, Filter, and Help menus, the Menu Bar consists of buttons that launch the Create Connector tool and allow you to create new connectors. The figure above displays the Create Connector window for creating a TimedConnector.

The following table gives you an overview of each menu bar item.

Connector

Use the Connector buttons to create connectors. A connector is represented by an arrow that starts at a source node and ends at a destination node. The types of connectors available are:

  • An UpdateConnector subscribes to receive notifications from the source node. In other words, when the value of the source node changes, the destination node is updated. UpdateConnectors are displayed as blue arrows.
  • A TimedConnector polls for data from the source and updates the destination periodically. Timed connectors are associated with an LEC server poll class that defines the polling period. Poll classes are defined as setup node in the configuration VMD. TimedConnectors are displayed as pink arrows.
  • A DemandConnector reads from the source node whenever another connector or device reads from the destination node. DemandConnectors are displayed as purple arrows.
  • A TwoWayConnector subscribes to receive notifications from the source node and the destination node. In other words, when the value of the either node changes, the other node is updated. TwoWayConnectors are displayed as green arrows.
  • An ImplicitConnector is a connector created automatically by the Configuration Manager when using one node as a parameter input to another node. ImplicitConnectors are displayed as brown arrows.
Start / Stop Service

Use the Start service or Stop service button to start or stop the LEC service for the currently selected configuration alias.
