Purpose

The communication module provides communication via the ETHERNET bus. ETHERNET connection can be established directly to the communication module, an additional switch is not necessary.

The ETHERNET communication module is an intelligent 100-base-T-ETHERNET communication interface based on the highly integrated netX100 micro-controller. The complete TCP/IP protocol and the application layers are supported.

The user interface is based on a dual-port memory. The ETHERNET communication runs via RJ45 interfaces.

The communication module is configured via the dual-port memory, the diagnosis interface or a TCP/IP connection by means of a system configurator.

Note

It is not possible to close a RSTP ring by using the two ports of the communication module.

Applications:

• TCP/IP for PC/ Automation_Builder (programming)
• UDP (communication via the Function Blocks ETH_UDP_SEND: ETH_UDP_SENDETH_UDP_REC: ETH_UDP_REC
• MODBUS on TCP/IP (MODBUS on TCP/IP, client and server)

For use in extreme ambient conditions (e.g. wider temperature and humidity range), a special XC version of the device is available.
