Redundancy

With Vertex-Pro dual-redundant models, the CPU modules operate in a special master/slave

configuration, using synchronized memory and one-millisecond transfers to ensure bumpless transfers,

and allow on-line repairs, and program changes, to increase overall system availability. These models

allow for automatic and/or manual transfers between the two sets of modules in cases of external I/O,

internal module, or input power failures. Dual-redundant models allow any module to be replaced while

the unit is operating on-line. Annunciation of any control failure or transfer is provided through all

communication links and event logs.

Configurability

The following I/O list is utilized by Vertex-Pro models only. Vertex-Pro-C models are customized to the

specific application and may use the same, or more or less I/O signals, depending on the application.

Vertex-Pro inputs and outputs (I/O) are arranged into pre-defined and configurable groups. Pre-defined

I/O is fixed based on its use in all or most applications. Configurable I/O is selected based on the specific

needs of each application.

Applications

The Vertex-Pro anti-surge control is designed for industrial-sized axial or centrifugal compressors with 1

to 4 recycle loops. Standard off-the-shelf models are available and field configurable for 1 or 2 recycle

loop applications, while custom models are available for larger 3 or 4 recycle loop applications. This

controller includes specifically designed algorithms and logic to start, stop, control, and protect industrial

compressors driven by a stationary speed motors or variable-frequency drive motors. OEM-qualified

algorithms are used within the Vertex-Pro for straight-through, iso cooled, double-flow, single side-

stream, and back-to-back compressor applications.

Designed to replace CCC Series-3 and Series 3++ anti-surge controllers, the Vertex-Pro can be configured

to function like these controllers but uses two-times faster scan rates, improved surge anticipation logic,

and one integrated package for all control functions (anti-surge control loop 1. anti-surge control loop 2. 

performance control, and dual-redundant control).

The standard Vertex-Pro models (1 & 2 recycle loops) are field-configurable, allowing users to

configure/select the specific control algorithm required for the specific compressor loop and application.

Since 3–4 loop compressor applications tend to be complex, Vertex-Pro-C models (3 & 4 recycle loops)

are custom programmed by Woodward engineers, ensuring that the correct control and optimization

algorithms are used to meet the specific application requirements.

For critical applications requiring increased reliability and availability, users can order dual-redundant

control models, which have manual switch-over and automatic fail-over capabilities. These redundant

control models also allow users to replace/repair modules and perform program changes while the

compressor is operating on-line, thus greatly improving system availability.

The Vertex-Pro controller includes the following PID control & protection functions:

 Anti-Surge PID Control

 Rate PID Control

 Boost (open-loop backup line response)

 Surge Recovery

 Surge Minimum Position

 Start, Purge, Stop, Shutdown, & Zero Speed Sequencing Positions

 Alarm & Shutdown Logic

Alternatively, the following functions can be configured, depending on the application requirements:

Motor

 Current limit PID Control

 Start Sequence Logic

Compressor

 Throttle or Inlet Guide Vane Ramp Loading (motor protection)

 Performance Control (compressor suction or discharge pressure, flow, or external signal)

 Load Sharing (parallel compressors up to three trains)

The Vertex-Pro is built on Woodward’s field-proven MicroNet™ platform, and is available in simplex

or dual redundant models. All models utilize the MicroNet’s compact 8-slot chassis and

robust field termination modules. Simplex models include one of every module, while

dual-redundant models include two of every module, allowing users to perform both

bumpless on-line program changes and on-line module replacements.

The Vertex-Pro chassis is designed to be bulkhead-mounted in a cabinet or control

panel, and contains the required I/O and core control software to control industrial

motor-driven compressors. Typically, this controller is located in an enclosure that is

rated for the site-specific environment. Field termination modules (with integrated

circuit fuse protection) are included with this controller to allow users to easily land

and manage compressor and system interface wiring. The control also supplies

source power for associated sensors and I/O circuits.

This control is field-configurable, allowing users to easily configure the control to

application-specific requirements.

A menu-driven software program (Control Assistant) is provided with the control,

and when installed on any Windows based computer or laptop, serves as the human

interface to the control and or compressor.

This Control Assistant is used to configure, service, and optionally operate the control.

Optionally a touchscreen OpView™ panel is available for use as a local or remote

operator control panel. This OpView panel is comprised of a 307 mm (12.1”) touchscreen 

computer, and connects to the control via an Ethernet link.
