Application TCP Connection Configuration
3.6.3. Application TCP Connection Configuration
Use this area to configure application TCP connection settings for a serial or socket port using the
appropriate Edit Port Configuration page.
Application TCP Connection Configuration (Serial or Socket Port)
Enable
Enables/disables the
Application Socket
Interface. Enabling this
function allows an
application to be
connected to the device
serial/socket port.
If both the PLC and
application are connected
to the device serial/socket
port, both can transmit to
and receive data from the
serial/socket port.
However, the PLC and
application cannot communicate directly to each other.
Listen
Enabling this setting allows the application to connect to the DeviceMaster UP via an
Ethernet TCP/IP socket.
• Not selected - Disables listening and the DeviceMaster UP does not accept
connection attempts.
• Selected - Enables listening and the DeviceMaster UP accepts connection attempts
from the specified Listen Port.
Listen Port
The socket port number on the DeviceMaster UP the application connects to if the
Application Listen Enable is selected.
Connect To Mode
Specifies if and how the DeviceMaster UP attempts to connect to the application at the
specified Connect IP Address and Connect Port.
• Never - The DeviceMaster UP does not attempt to connect to the application.
• Connect-Always - The DeviceMaster UP attempts to connect to the application until
a connection is made.
• Connect-On-Data – The DeviceMaster UP does not attempt to connect to the
application until there is data to send to the application. Once data is received from
the serial/socket device, the DeviceMaster UP attempts to connect to the
application until a connection is made.
Connect Port
The application socket port number the DeviceMaster UP connects to if the Application
Connect To Mode is set to either Connect-Always or Connect-On-Data.
Connect IP Address
The application IP address the DeviceMaster UP connects to if the Application Connect
To Mode is set to either Connect-Always or Connect-On-Data.
