CPS Fire Safety
The NK8000 family provides LAN/WAN adapter products for a safety and security
network:
NK822x series (no longer available, end of service: 31 December 2015)
⚫
NK823x Ethernet Ports series (NK8231, NK8232, NK8235)
⚫
NK8237 Modbus Gateway
⚫
NK8237 IEC 60870-5-104 Gateway
⚫
NK822x series
The includes:
NK8222 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
⚫
communication unit supporting one subsystem connection over RS232 line or
CerCom/LON bus, and locally connected DF8000 I/O units. It can provide local
interactions between points in the connected subsystem and I/O.
NK8223 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
⚫
communication unit supporting up to 4 RS232 lines, one CerCom/LON bus,
and locally connected DF8000 I/O units. It can provide local interactions
between points in the connected subsystems and I/O.
NK8225 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
⚫
(CEI-79) communication unit supporting up to 4 RS232 lines, one
CerCom/LON bus, and locally connected DF8000 I/O units. It can provide local
interactions between points in the connected subsystems and I/O, as well as
network-wide over other NK8225s or NK823xs.
NK823x series
The includes:
NK8231 CEI Interface for a single subsystem: LAN/WAN/Dial-up (CEI-79)
⚫
communication unit supporting one subsystem connection over RS232 line as
well as onboard I/O and locally connected DF8000 I/O modules.
Note: NK8231 is intended for use with MM2000 Management Stations, which are
only available in the Italian market.
NK8232 Ethernet port (single): LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and
⚫
Dial-up (CEI-79) communication unit supporting one subsystem connection
over RS232 line as well as onboard I/O and locally connected DF8000 I/O
modules. It can provide local and interactions between points in the connected
subsystems and I/O, as well as network-wide interactions over other NK8225s
or NK823xs. In addition, it can act as Modbus Gateway and IEC 60870-5-104
Gateway for FS20/STT20/FS720.
NK8235 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
⚫
(CEI-79) communication unit supporting up to 4 RS232 lines as well as
onboard I/O and locally connected DF8000 I/O modules. It can provide local
interactions between points in the connected subsystems and I/O, as well as
network-wide interactions over other NK8225s or NK823xs. In addition, it can
act as Modbus Gateway and IEC 60870-5-104 Gateway for
FS20/STT20/FS720.
Note: The Modbus host interface is discussed in the NK8237 Modbus Gateway
ICC manual, (document A6V10316241). This document should be used for
configuring the Modbus host also on NK8232 and NK8235.
Note: The IEC 60870-5-104 host interface is discussed in the NK8237 IEC 60870-
5-104 Gateway ICC manual, (document A6V10854379). This document should
be used for configuring the IEC 60870-5-104 host also on NK8232 and NK8235.
