Introduction

On the Control Expert Channel Properties page, you can select a Source IP Address (PC) from a pull-down menu.

The Source IP Address (PC) menu is a list of IP addresses that are configured for a PC that has the Control Expert DTM installed.

To make the connection, choose a Source IP Address (PC) that is in the same network as the CPU and the device network.

You can execute these tasks through this connection:

  • Perform fieldbus discovery.

  • Execute Online Actions.

  • Send an explicit message to an EtherNet/IP device.

  • Send an explicit message to a Modbus TCP device.

  • Diagnose modules.

Open the Page

View the Channel Properties for the CPU:

Step

Action

1

Open a Control Expert project that includes a M580 CPU.

2

Open the DTM Browser (Tools > DTM Browser).

3

In the DTM Browser, find the name that you assigned to the CPU.

4

Double-click (or right-click Open) the name of the CPU to open the configuration window.

5

Select Channel Properties in the navigation pane.

Property Descriptions

This table describes the parameters for the Channel Properties:

Parameter

Description

Source Address

Source IP Address (PC)

A list of IP addresses assigned to network interface cards installed on your PC.

NOTE: If the configured main IP address of the CPU is not in the subnet of any of the IP configured on the interface cards of the PC, then the first interface card IP is suggested by default.

Sub-Network Mask (read-only)

The subnet mask that is associated with the selected source IP address (PC).

EtherNet/IP Network Detection

Begin detection range address

The first IP address in the address range for automatic field bus discovery of EtherNet/IP devices.

End detection range address

The last IP address in the address range for automatic field bus discovery of EtherNet/IP devices.

Modbus Network Detection

Begin detection range address

The first IP address in the address range for automatic field bus discovery of Modbus TCP devices.

End detection range address

The last IP address in the address range for automatic field bus discovery of Modbus TCP devices.

Make the Connection

Connect to the Source IP Address (PC):

Step

Action

1

Select an IP address from the Source IP Address (PC) pull-down menu.

2

Press the Apply button.

3

In the DTM Browser, find the name that you assigned to the CPU.

4

Right-click the name of the CPU and scroll to Connect .

TCP/IP Monitoring

Expand (+) the Channel Properties heading in the configuration tree and select the TCP/IP item at level 1.

The read-only information on this page monitors the IP parameters that were configured in Control Expert.

Managing Source IP Addresses for Mulitple PCs

When you connect a PC to a DTM-based Control Expert application, Control Expert requires that you define the IP address of the PC connected to the PLC, which is referred to as the source IP address (PC). Rather than having to perform a Build in Control Expert each time you connect a PC to the PLC, the source IP address (PC) is selected automatically when you import the Control Expert application. During application import, the DTM retrieves all available configured NIC addresses of a connected PC and matches the subnet mask of the master with the available NIC list.

  • If a match between the subnet mask of the master and the NIC list exists, Control Expert automatically selects the matched IP address as the source IP address (PC) in the Channel Properties page.

  • If multiple matches exist, Control Expert automatically selects the IP address nearest to the subnet mask.

  • If no match exists, Control Expert automatically selects the IP address to the nearest available subnet mask.
