Connect Method

Description
Connects the Spel class instance with a Controller.

Syntax
Sub Connect (ConnectionName As String)
Sub Connect (ConnectionName As String, ConnectionPassword As String)
Sub Connect (ConnectionNumber As Integer)
Sub Connect (ConnectionNumber As Integer, ConnectionPassword As String)

Parameters

• ConnectionName
  A character string indicating the connection name.
• ConnectionNumber
  An integer indicating the connection number. The connection number is the number of the connection in the RC+ Setup \ [PC to Controller Communications] dialog. Specify a value of -1 to use the last successful connection.
• ConnectionPassword
  A character string indicating the connection password. If the controller requires a password for connection but the password has not been configured in the RC+ Setup \ [PC to Controller Communications] dialog, you must set the password to connect with the controller.

Remarks
When a Spel class instance needs to communicate with the Controller, it automatically connects. If you want to explicitly connect to the Controller, use the Connect method.
