Max 10,000. This includes all the physical elements of the FC20/FC720 control
units.
IEC Master device/station
Up to four IEC 60870-5-104 Host protocols can be handled, via TCP/IP connection:
⚫
TCP/IP connection: IEC server for four TCP/IP client connections. Separate
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.
Note: Due to the limits of two BACnet clients per FS20/FS720 site, there is a limit
of two NK8237 clients per site. For larger FS20/FS720 sites you may need to split
the site into smaller sites.
