4.12 Fieldbus Configuration - Ethernet
The 105G provides the following Ethernet functionality:
1. Modbus/TCP. The module supports the Modbus/TCP protocol and conforms to the
Modbus/TCP specification 1.0 (full information on this protocol can be obtained from
http://www.modicon.com/openmbus/index.html). Refer to section 4.12.2 below for
configuration details.
2. EtherNet/IP. EtherNet/IP is based on the Allen-Bradley Control and Information
protocol, CIP, which is also the framework for both DeviceNet and ControlNet, to carry
and exchange data between nodes. Refer to section 4.12.3 below for configuration
details.
Note! The 105G only supports EtherNet IP I/O Messaging like those found in A-B
ControlLogix, and CompactLogix PLC’s. Earlier A-B Ethernet based PLC’s, i.e.
SLC5, Micrologix are not supported as they use Explicit Messaging.
3. IT-Functionality. The Ethernet 105G has several IT features, including Internet
functionality.
• Filesystem. The module features a flexible file system with two security levels. The size
available for user files is approximately 1.4 Mbyte of non-volatile memory.
• FTP Server. The FTP Server provides easy file management using standard FTP clients.
• Telnet Server. The Telnet server features a command line interface similar to the MS-
DOS™ environment.
• HTTP Server. The module features a flexible HTTP server with SSI functionality. This
enables the user to configure a web interface (or web page) accessing I/O values in the
105G.
• Email Client (SMTP). Predefined messages stored within the file system can be sent,
triggered by a specified I/O value in the 105G. It is also possible to include I/O values in
emails, using SSI functionality.
• IP Access Control. It is possible to configure which IP addresses and what protocols that
are allowed to connect to the module.
For further details, refer to Appendix 2.
4.12.1 Setting IP Address
The Ethernet IP address can be set from the configuration software or via the Ethernet port or via
the selector switches in the top end-plate of the module. If the “Enable Switch Address” box is
not selected, then the address entered in the program will be used and the switch value ignored.
The IP address can be overwritten from the Ethernet port. If the “Enable Switch Address” box is
selected, then the address entered in the configuration program will be ignored and the rotary
switch read on start-up of the 105G.
The IP address is used to identify each node on the Ethernet network. Therefore, each node on
the network must have a unique IP address. IP addresses are written as four decimal integers (0-
