Series 5 Vanguard Controllers provide a flexible combination of CCC and third-party
components:
- Turbomachinery-specific mix of high-speed local I/O
- Remote I/O
- ProfiBus controllers and slaves
- Rack-mountable chassis with a standard cPCI bus
Series 5 Vanguard controllers utilize a
fully deterministic, multitasking operating
system. Automation and control
programs, including our time-tested
algorithms for antisurge protection and
loadsharing, are implemented using the
IEC-61131 programming standard.
Windows-based TrainTools suite provides
a comprehensive interface for
programming and project engineering.
Powerful, High-Speed Processor
Vanguard is designed to meet the automation and control needs for a majority
of turbomachinery trains, no matter how
complex. Its powerful processor and
multitasking operating system have
been specifically tailored to combine
high-speed control loops with sequencing logic.
Vanguard incorporates advanced self-diagnostic features, particularly in
early I/O failure detection, reducing probability of nuisance
shutdowns.
Vanguard supports a cost-effective and highly
scalable distributed I/O sub-system, a comprehensive Windows-based
tools suite, including a flexible programming environment, and fast and reliable communication links, including both
Ethernet and serial ports.
The standard MPU card provides three 100 MB Ethernet ports
for communication with our TrainTools workstations, and four
electrically-isolated RS-485 serial ports for communicating with
Modbus masters or other Series 5, Series 4, or Series 3 Plus
Controllers.
Fast Execution Speeds
Vanguard’s fast sampling and execution rates help in detecting I/O failures
before the signals are actually used
in the control or logic program. Fast
scan rates also permit the use of
more advanced control algorithms,
primarily aimed at improving
disturbance rejection response of the system and minimizing
operator intervention. For example, field tests show that Vanguard can execute a demanding fuel control application for a
low NOx gas turbine with a multitude of control loops in less
than 10 milliseconds.
CCC’s patented, field-tested and
comprehensive surge protection and capacity control algorithms
also show improved response resulting from faster execution
and scanning rates.
High Resolution Time Stamping
Vanguard’s fast scanning and execution rates not only benefit
the quality and reliability of control, but also permit
reconstruction of significant events with resolution equal to the
loop time of the controller. An on-board clock is used to time
stamp process variables, alarms, and events generated by the
controller. The data and its associated time stamp are archived
on the TrainTools workstation, and can be available to other systems through an OPC interface.
Specialized Local I/O
Vanguard’s chassis-based local I/O card (IOC) is designed to
handle critical I/O points that require high processing speeds,
such as frequencies from magnetic pick-ups for measurement of
rotational speed. The IOC scans and processes I/O within 2.5
milliseconds. A Vanguard local I/O card combines 22 analog
inputs, 6 analog outputs, 6 frequency inputs, 16 digital inputs,
and 14 discrete outputs in one economical package. Based on
CCC experience, this I/O mix can satisfy high-speed I/O
requirements for many turbomachinery trains.
However, if
necessary multiple IOCs can be installed in the Vanguard chassis.
Field wiring is connected to up to four field termination assemblies
(FTAs): two for analog signals and two for discrete signals. These FTAs can be equipped with a full range of conditioning modules,
including RTD and thermocouple inputs. While Vanguard controllers are compatible with both CCC and third-party
signal conditioning modules, our exclusive, custom-designed
conditioning modules provide high and low operating
temperatures extraordinary transient voltage protection, opencircuit
detection, and compatibility with turbomachinery-specific
field devices.
In duplex systems, each pair of redundant I/O cards share the
same FTAs, so failed cards can be replaced without disturbing
your field wiring. Both simplex and duplex FTAs support redundant
power supplies.
The IOC features comprehensive on-board diagnostics and
cooperates with the MPU to trigger redundant system
switchovers. By sampling each channel at sub-millisecond rates, it
assures overall process stability and minimizes process disturbances.
Secure Remote I/O
Logic and other lower-speed applications utilize ProfiBus remote I/O,
an industry standard for high-speed serial communication between a
controller and remotely-located, multi-channel slave assemblies. This
is implemented by installing a ProfiBus Master (PBM), usually in
combination with our SureLink Remote I/O Assemblies.
Using a certified PBM installed in the Vanguard chassis, a
twisted pair field I/O network can reduce installation costs. The
modular design provides for scalable projects and for subsequent
I/O expansion without the fear of running out of capacity.
The
Remote I/O bus can be used for hundreds of I/O points while
maintaining high performance. With up to a 12
Mb/s communication bus, multiple masters
and a redundant power supply distribution,
the network can easily grow to over 1,000 points.
Local I/O is used for high-speed PID-control,
while Remote I/O is utilized for plant-wide
logic and unit control. The integration of I/O
type is seamless, and the user sees no
distinction. All PC tools and turbomachinery
control applications operate invariant to the
type of physical I/O used in the project, and all machine train
algorithms are executed in the same common processor.
Simplex or Duplex Chassis
The MPU, IOC, and Remote Carrier Card with ProfiBus Master
are installed in a 19-inch rack-mount chassis featuring a
standard compact Peripheral Component Interconnect (cPCI)
bus. Both simplex and duplex chassis are available, either of
which can have duplex power supplies:
- The simplex chassis has a single cPCI bus that accommodates one MPU and either five local or three local and one remote I/O cards.
- The duplex chassis has two cPCI buses, requires redundant MPUs (one for each bus), and accommodates either three local or one local and one remote duplex I/O cards.
Each component card is installed from the front of the chassis,
and has a matching transition module that installs from the back.
Front panel serial and Ethernet ports are provided for set-up and
maintenance purposes.
