Description

AIP532   Integrated Production Control System CENTUM VP

1. Overview of CENTUM VP FCS
Yokogawa developed all the CENTUM Series Field Control Stations (FCSs), including
hardware and software, by our own selves. We know every corner of the software and
the hardware and that knowledge enables us to sustain the service record of 99.99999%
availability.
1.1 Compact Design
The size of each component is designed compact that reduces the overall “footprint” of the
control system. It allows make efficient use of the limited spaces of the control and equipment
rooms. Both the FCS and its I/O node units can be placed in remote classified locations (IEC
Zone2/Class I Div. 2), that provides savings in installation costs.
1.2 Dual-redundancy and Reliability
There is no single point of failure in Yokogawa’s FCS! The processor modules, power supplies,
and I/O modules, including the communication bus, support a redundant configuration. The
robustness of the FCS comes from this configuration known as “Pair and Spare” and the
reliability of calculation results is guaranteed through real-time validation. Two processor
modules have two MPUs each. MPU 1 and MPU 2 in the primary processor module are always
comparing the calculation result, and if the results do not match, the first processor module goes
into maintenance mode while the secondary processor module takes over process control. In
order to make this switch over seamless, MPU 3 and MPU 4 are also calculating and comparing
the results while the primary processor module is active. Pair and Spare is Yokogawa’s unique
technology, supporting impressive levels of availability for CENTUM and ProSafe-RS. This
architecture has been approved by TÜV Rheinland for safety instrumented systems. The
ProSafe-RS certification was granted to Yokogawa in exceptionally short period of time, and it
was due in-part to our Pair and Spare technology.
1.3 Online Maintenance
Through an online maintenance function, FCS applications can be modified without shutting
down the FCSs. It means, you can change logics and parameters without interrupting the
process control. This is useful for expansion or modification of the plant in operation.
1.4 Open Structure and High Reliability
Yokogawa is committed to reduce costs for our customers by enabling the use of commercial
off-the-shelf technology where appropriate. Third-party cables, switches and other network
communication devices can be used with Yokogawa’s Ethernet based Vnet/IP. Plant reliability is
in no way compromised as the communication response is guaranteed (deterministic as opposed
to probabilistic) thanks to Yokogawa’s renowned reliability, dedicated protocol, and redundant
configuration.

1.5 Function Blocks
The CENTUM VP provides functional blocks for monitoring, control, manipulations, calculations,
logic functions, and sequences. Not only continuous control but also advanced control,
complicated sequence control, and batch control are all executed in a redundant, secure, and
reliable controller environment. Plant systems can be flexibly designed, ranging from small- to
large-scale, through the combination of these control blocks.
1.6 Subsystem Integration and Digital
Fieldnetworks Support
To meet the growing need for communication with manufacturing equipment including variable
speed drives, PLCs, and “smart” motor protection relays for operation and monitoring, as well
as with analyzers, weighing machines, smart instruments, and other instruments used for
product inspection, CENTUM VP supports a wide variety of communication interfaces and digital
fieldnetworks such as FOUNDATION fieldbus, PROFIBUS-DP, Modbus RTU, Modbus TCP/IP,
and DeviceNet.
1.7 Unit Instruments
The multiple devices of a process facility which would previously have been handled individually
can now be defined, operated, and monitored as a single unit, simplifying operation. Unit
instruments can be applied to batch processes and continuous control processes that require
complex management, expediting overall plant operation.
