Ethernet interface

Application

The control is provided with an Ethernet interface as a standard feature so that you can integrate it into a network.

Description of function

The control transfers data via the Ethernet interface using the following protocols:

  • CIFS (common internet file system) or SMB (server message block)
  • The control supports versions 2, 2.1 and 3 of these protocols.

  • NFS (network file system)
  • The control supports versions 2 and 3 of this protocol.

Connection options

You can integrate the Ethernet interface of the control into the network or connect it directly to a PC through the RJ45 connection X26. The connection is electrically isolated from the control electronics.

 
Tip

The maximum cable length permissible between the control and a node depends on the quality grade of the cable, the sheathing, and the type of network.

You can execute the following functions:

 
Tip
  • If you have changed the profile of an active connection, the control will not update the profile being used. Reconnect the corresponding interface with Reconnect.
  • The control exclusively supports the Ethernet connection type.

The DHCP server tab

The machine manufacturer can use the DHCP server tab in the control to configure a DHCP server in the machine network. Using this server, the control can establish connections with other network components of the machine network (e.g., with industrial computers).

Refer to your machine manual.

You can check the network connection on the Ping/Routing tab.

The Ping/Routing tab contains the following information and settings:

Area

Information or Setting

Ping

Address:Port and Address:

You can enter the IP address of the computer and possibly the port number for checking the network connection.

Entry: Four numerical values separated by dots and, if necessary, a port number separated by a colon (e.g., 10.7.113.10:22)

As an alternative, you can enter the name of the computer whose connection you want to check.

Starting and stopping the test

  • Start button: starts the test
  • The control displays status information in the ping field.

  • Stop button: stops the test

Routing

The control displays status information of the operating system about the current routing for network administrators.

The SMB share tab

The SMB share tab is included only in connection with a VBox programming station.

When the check box is active, the control releases areas or partitions protected by a code number for the Explorer of the Windows PC used, e.g. PLC. You can activate or deactivate the check box only by using the machine manufacturer code number.

In the TNC VBox Control Panel, select a drive letter within the NC share tab for displaying the selected partition and then connect the drive with Connect. The host displays the partitions of the programming station.
