Configure a DDE data source object

Add a DDE data source object to your Gateway Communication Driver hierarchy

1. Right-click Configuration in the hierarchy, and select either Add DDE Connection.

   • A new object is created in the hierarchy tree and is named New_DDE_000 by default.

   • In this step and succeeding steps, each hierarchy entry is added in "edit mode," providing a convenient place for you to appropriately name components of your specific environment. If you do not rename the object at this time, the numeric sequence system is applied. Any hierarchy entry can be renamed at a later time.

     The New_DDE_000 Parameters configuration view (right pane) is displayed.

2. Configure the new DDE object according to the following option definitions:

   • Server Name: Name of the DDE or SuiteLink server you want to use as a data source (for instance, DASABTCP). Default value is MyServer. Server Name can be from 1 to 32 characters long (cannot be blank), and all printable characters are allowed except a space and > : " / \ | , . ; ? ' [ ] { } ` ~ ! @ # $ % ^ & * ( ) _ + - =.

   • Reconnect Attempts: Number of times Gateway Communication Driver attempts to reconnect to the specified data source if a connection fails. The value minus one (-1) means no limit to the number of attempts. The value zero (0) means no attempts. Minimum/maximum range is -1 to 1,000,000. Default value is 3. Entry of a value that is excessively out of the allowed range will display an error message about illegal format.

   • Reconnect Period: Delay (in ms) between reconnection attempts if a connection fails. Minimum/maximum range is 10,000 to 300,000 ms (corresponding to the range of 10 sec to 5 mins). Default value is 30000 ms. Entry of a value that is excessively out of the allowed range will display an error message about illegal format.
