Device TCP Connection Configuration
The following table provides information about configuring the Device TCP Connection Configuration area.
Device TCP Connection Configuration
Enable
This setting enables/disables the Device Ethernet Device. Enabling this function
allows an Ethernet TCP/IP device to be connected to a PLC and/or application. If
both the PLC and application are connected to the device, both can transmit to and
receive data from the device socket port. However, the PLC and application cannot
communicate directly to each other.
Listen
Enabling this setting allows the device to connect to the DeviceMaster UP via an
Ethernet TCP/IP socket.
• Not selected - Disables listening; the DeviceMaster UP does not accept
connection attempts.
• Selected - Enables listening; the DeviceMaster UP accepts connection attempts
from the specified Listen Port.
Listen Port
This is the socket port number on the DeviceMaster UP the application connects to
if the Device Listen Enable is selected.
Connect To Mode
This setting specifies if and how the DeviceMaster UP attempts to connect to the
device at the specified Connect IP Address and Connect Port.
• Never - The DeviceMaster UP does not attempt to connect to the device.
• Connect-Always - The DeviceMaster UP attempts to connect to the device until a
connection is made.
• Connect-On-Data - The DeviceMaster UP does not attempt to connect to the
device until there is data to send to the device. Once data is received for the
device, the DeviceMaster UP attempts to connect to the device until a
connection is made.
Connect Port
The device socket port number the DeviceMaster UP connects to if the Device
Connect To Mode is set to either Connect-Always or Connect-On-Data.
Connect IP Address
The device IP address the DeviceMaster UP connects to if the Device Connect To
Mode is set to either Connect-Always or Connect-On-Data.
Disconnect Mode
This setting specifies if and how the DeviceMaster UP disconnects from the device.
• Never - The DeviceMaster UP does not disconnect from the device.
• Idle - The DeviceMaster UP disconnects when there has been no transmit or
received data between the device and PLC/application for a specified Idle Timer
period.
Idle Timer
The idle timeout period in milliseconds that is used if the Device Disconnect Mode is
set to Idle.
