The BMENOS0300 module is an inexpensive, easy-to-use network switch that is configured exclusively by means of the two rotary switches. Because the BMENOS0300 is a switching module, there is no need for it to provide ACL protection to IP based services. All Ethernet packets are pass through. Hence protection can be provided for the connected end devices (such as the CPU and the Ethernet I/O adapter module).
The BMENOS0300 module accepts Ethernet packets sent to its Ethernet ports from connected Ethernet devices. If you wish to limit the inflow of Ethernet packets into your application, you can enable Access Control in the Security tab of the M580 CPU module DTM. Access Control restricts device access to the CPU in its role as a server. You can add the IP addresses of the devices that you want to communicate with the CPU to the list of Authorized Addresses.
