Communications

Ethernet Security

The Com’X supports two separate Ethernet networks for isolated device network, for two separate infrastructure backbones, or for a switched network.

Wireless Security

Your Com’X wireless network can be secured with WPA2 (recommended),WPA, or WEP.

Modbus TCP/IP Filtering

The Modbus TCP/IP filtering feature controls which IP addresses are allowed to communicate with the Com’X and its downstream devices using Modbus TCP/IP.

Minimizing the number of IP address that can access the device reduces the likelihood of unauthorized intrusions.

This feature is disabled by default. When enabled, the default access level is Read for any Modbus TCP/IP client not in the filtered list. Setting the Default Access field to None blocks all Modbus TCP/IP clients not in the filtered list.

It is recommended that you enable this feature, if your system architecture permits.
