Application Socket Configuration
Use the Application Socket Configuration connection only for connecting to an application such as a
configuration, database, telnet, or a control application when you want to communicate to a serial or Ethernet
device.
Note the following:
• When the application socket is connected to an application, it will allow the application to send and
receive data from the serial or Ethernet device.
• The application socket cannot send data directly to the PLC. Nor can the PLC send data directly to the
application.
• If the PLC interface is also enabled, data received from the serial or Ethernet device will be sent to both
the PLC and application.
• Do not connect the application socket to the DeviceMaster UP or to the PLC. This may cause
erroneous operation.
Use the following procedure to configure the application socket connection.
Application TCP Connection Configuration options are included on the Serial Device Configuration and
Ethernet Device Configuration pages. Access the appropriate configuration page using the following steps:
1. If necessary, access the Server Configuration web page by entering the DeviceMaster UP IP address in
your web browser or by highlighting the DeviceMaster UP in PortVision DX and clicking Webpage.
Note: If the browser does not display the web page correctly, clear the browser history and refresh the
DeviceMaster UP web page.
2. Click the Serial Device Configuration or Ethernet Device Configuration link.
3. Click the link for the appropriate Port or Socket number.
4. Scroll down to the Application TCP Connection Configuration options and click Enable. (Serial Device
Configuration page) or Enabled (Ethernet Device Configuration page).
