CENTUM CS3000
1.1 Hardware terminology The CS3000 is a distributed control system, which means that the “intelligence” to run the process resides in the control hardware in the process area. The CS3000 system has a maximum of 64 stations per domain, (16 Domains and 256 stations maximum) and 100,000 tags (expandable to 1 000 000 tags). Human Inter face Station (HIS) This station is used mainly for operating and monitoring plant functions. With optional engineering software, system builder functions can be defined. Field Contr ol Station (FCS) The FCS provides control of the plant functions through instruments in its database. Process information is placed on the Vnet and Vnet/IP for monitoring or control by an HIS. Processing speeds of 1 second (Standard), 500 ms, 200 ms, 100ms and 50ms are selectable for the function blocks. Vnet (Vnet/IP) This is the communication highway that links the system components together for control and monitoring functions. New instruments are downloaded to the FCS from the HIS via the Vnet (Vnet/IP). Vnet (Vnet/IP) runs at a 10 Mbits/1Gbits rate. Ethernet Ethernet communication link between HIS units used to download files from the PC with “builder” if Vnet is used. Vnet/IP is using Bus 2 for inter HIS communication (open communication) Vnet - process communication highway Type of Bus 10BASE-5=10- speed 10Mbps;BASE data transmission in the BASEBAND;5-500 distance between station(PC)[YELLOW CABLE THICK]1cm 10BASE-2=THIN=5mm type of communication BUS 1 "Control communication" BUS 2 "Open communication" Redundant it means BUS 1 + BUS 2.Both busses are divided to several layers BUS

Bus conver ter (BCV) The ABC bus converter is used to connect CENTUM 3000 to existing CENTUM-XL or Micro XL systems. The ABC is also used for splitting the CENTUM CS3000 into what are called Domains. Domain A Domain is a grouping of stations on a Vnet segment. CS3000 Domains can have up to 64 stations; the domain address range on the V net is 1-16. A maximum of 256 stations are allowed per CS3000 system. CS1000 is fixed as Domain 1 with a maximum of 24 station. When CS1000 is connected to a uXL, the uXL is assigned Domain 17.

1.2 Human Interface Station (HIS) The HIS is used mainly used for plant operation and monitoring, but can have system engineering and test function software installed. The test function allows the engineer to create and test control function without the use of an FCS. The HIS can also have an optional spill resistant operator keyboard. Since the HIS runs Windows XP, this allows the user to run standard Windows XP based applications, like MS Word , or Excel for spreadsheets.
Minimum Requir ements: CPU Pentium 800MHz or higher. Memory 128 MB for operations and monitoring. 256 MB for operations and builder. Hard Disk Drive 1 GB (2 GB recommended for using builder functions). CRT 17 inch or larger; 1024 x 768 (16 bit color depth colors). Station Addr essing There is a card in the HIS that defines its station number on the Vnet by the physical switch settings. Vnet STATION ADDRESS Switches

1.3 CS3000 Field Control Station The Field Contr ol Station, if purchased as redundant, has dual processor cards; each processor running dual RISC processors. Depending on the FCS purchased, memory will be 16/32MB. Data is transferred to and from the FCS via the Vnet. Data is transferred to and from the Field Control Unit and the Node Interface Unit via the ESB bus. The ESB bus can connect up to 10 Nodes to the FCS; each Node can have up to 8 I/O modules. ESB bus can be extended by ER bus (10 Mbs Ethernet network, 10BASE2, 10BASETP), connecting max. 15 nodes.

CENTUM CS3000 CONTROL DRAWING SOFTWARE MODULE ADDRESSING When a user creates an instrument (called a “function block”), it must be told which input point it will be using for reference or output point for control. This is accomplished in an engineering screen called a “Control Drawing”.
Using FIC100 (on the previous page) as an example, this is how the function blocks running in the processor know which I/O module to use.

6.2 Tag alarms standards Alarm functions shall be implemented using the data acquisition and shared processing equipment of the control system. All alarms shall be visually and audibly indicated and shall be connected to event logging facilities.
Standar ds Each tag in control system can have alarm detection option. For analog tag signals we can use L alarm, LL alarm, H alrm, HH alarm and Open loop alarm. Optionally we can use also deviation alarm. For digital tag signals we can use Status alarm and Change of state alarm. Tag alarming will be applied according process design requirements. We will use three levels of alarms: High Alarm (Critical alarms) Low alarm Log alarm Each alarm level gives its importance. High alarm is most critical alarm for the technology and in control system will have separate critical alarm display. Low alarm has lowest priority. Log alarm will not be represented on alarm screen, but will be written to alarm history file. By these alarm levels we can optimally manage our alarm strategy. Also each alarm will have audible and graphical representation. Each alarm will have graphical representation on the process screen and on alarm summary screen. Alarm Representation for analog signals: Bad Measure – High Alarm HH – High Alarm H – Low Alarm L – Low Alarm LL – High Alarm Bad Measure – include open loop, out of the measure range and other, according the control system capabilities. On the alarm summary screen we can clearly distinguish importance of the incoming alarms: Not acknowledge alarm – Blinking Acknowledge alarm remaining – Remain current alarm colour without blinking
