Ethernet ports can be used for BACnet/IP and IEC TCP/IP for maximum
protection of the safety network.
Each IEC 60870-5-104 Host must be connected to the same network. Each host IP
Address must be configured in the IEC Server parameters.
Only one connection is permitted from the same IP address Host.

of two NK8237 clients per site. For larger FS20/FS720 sites you may need to split
the site into smaller sites.
