1.2.1 Vnet/IP Stations
n HIS
An HIS serves as a human machine interface of the CENTUM system that is used for operation
and monitoring. Software packages installed on a computer or on a console HIS, consisting of a
computer and Open Display Console Assembly. You can install and run operation and monitoring
functions, and/or engineering functions on an HIS as necessary.
A Vnet/IP interface card is required to connect to Vnet/IP.
n ENG
An ENG is a station with engineering functions that performs CENTUM system conguration and
maintenance management. It can be the same station as the HIS.
A Vnet/IP interface card is required to connect to Vnet/IP.
n FCS
An FCS performs process control and manages communications with subsystems such as
PLCs.
The following types of FCS are available for Vnet/IP and FIO:
AFV30S: Field Control Unit (for Vnet/IP and FIO, 19-inch Rack Mountable)
AFV30D: Duplexed Field Control Unit (for Vnet/IP and FIO, 19-inch Rack Mountable)
AFV40S: Field Control Unit (for Vnet/IP and FIO, with Cabinet)
AFV40D: Duplexed Field Control Unit (for Vnet/IP and FIO, with Cabinet)
AFV10S: Field Control Unit (for Vnet/IP, 19-inch Rack Mountable)
AFV10D: Duplexed Field Control Unit (for Vnet/IP, 19-inch Rack Mountable)
n APCS
An APCS performs control functions with a station to improve advanced control and plant
eciency.
The APCS requires installation of the “LFS1200 APCS Control Functions.” A Vnet/IP interface
card is required to connect to Vnet/IP.
n UGS
A UGS is a station that integrates subsystem controllers such as STARDOM controllers (FCN/
FCJ) or third party PLCs with the CENTUM VP system. It is connected by subsystem controllers
and various communication protocols such as Modbus, EtherNet/IP, and OPC DA. Similar to the
FCS, you can operate and monitor UGS from the HIS.
The UGS requires installation of the “LBC1500 Unied Gateway Station Standard Function
(UGS).” A Vnet/IP interface card is required to connect to Vnet/IP.
