This section discusses the Modbus configuration pages:
• TCP/IP Configuration Pages on Page 38

• Remote Modbus/TCP Device Configuration Page on Page 40
• Modbus Alias Device ID Configuration Page on Page 41
• Shared Memory Configuration Page on Page 41
4.1. TCP/IP Configuration Pages
This subsection discusses the Modbus over TCP Overview (not Modbus/TCP) Page and Modbus over TCP (not
Modbus/TCP) Socket Configuration Page for the Ethernet TCP/IP interface.
Each Ethernet TCP/IP interface provides connectivity to either Modbus/RTU or Modbus/ASCII masters. All request
messages received from the Ethernet TCP/IP interface are forwarded to the routing process which, in turn, forwards
the messages to either local or remote Modbus slave devices.
Note: The Ethernet TCP/IP interfaces are not directly tied to a serial port. All messages received over the Ethernet
TCP/IP interface receive the same local and remote routing capabilities as messages received over the
Modbus/TCP or serial Master interfaces.

4.1.1. Modbus over TCP Overview (not Modbus/TCP) Page

Access the Modbus over TCP Overview (not Modbus/TCP) page by clicking Modbus | TCP/IP Configuration and the
following page appears. This page provides an overview of the settings for each socket.

4.1.2. Modbus over TCP (not Modbus/TCP) Socket Configuration Page

Access the Modbus over TCP (not Modbus/TCP Socket Configuration page by clicking Modbus | TCP/IP
Configuration | Socket x. The following table provides information about each configuration setting.

Modbus Menus
• Modbus/RTU-to-Master - Configures the TCP/IP connection(s) to
communicate to Modbus/RTU master(s).
• Modbus/ASCII-to-Master - Configures the TCP/IP connection(s) to
communicate to Modbus/ASCII master(s).
If selected, this TCP/IP socket interface will be enabled.
If selected, the TCP/IP socket interface will listen for a connection at the specified
Listen Port.
