505 (Enhanced) Control
[Now with Enhanced Software for all Sizes of Industrial Steam Turbines]
The 505 (Enhanced) control is designed to operate industrial steam turbines of all sizes and applications. It includes specifically designed algorithms and logic to start, stop, control, and protect industrial steam turbines or turbo-expanders, driving generators, compressors, pumps, or industrial fans. The control's unique PID structure makes it ideal for applications where it is required to control steam plant parameters like turbine speed, turbine load, turbine inlet or exhaust header pressure, or tie-line power. The control's special PID-to-PID logic allows stable control during normal turbine operation and bumpless control mode transfers during plant upsets, minimizing process over- or undershoot conditions. The 505 (Enhanced) control senses turbine speed via passive or active speed probes and controls the steam turbine through one or two (split-range) actuators connected to the turbine inlet steam valves. For critical applications requiring increased reliability and redundancy, optionally two 505 controls can be connected in a redundant configuration to increase overall system availability.

505CC-2 Integrated Turbine Compressor Control
[1- or 2-Valve Steam Turbine/1- or 2-Stage Compressor or Motor-Driven Compressor]
The 505CC-2 is a microprocessor-based control with integral application software designed to control a single-valve or two-valve steam turbine and its one- or two-stage compressor load, or motor-driven compressors. The turbine control architecture is patterned after the popular 505 and 505E turbine controls. The anti-surge control provides the user with a choice between two algorithms-the standard Woodward anti-surge algorithm or a special "minimum transducer" design that adapts to variable molecular weights. Like the 505, the 505CC-2 uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module contains the basic I/O for turbine control. An Analog I/O module interfaces with the signal I/O associated with the one- or two-stage load compressor. The main processor and an Ethernet port are located on the Pentium CPU module. In addition, a Power Supply module (24 Vdc) is provided to power the entire control assembly. The modules are stacked into a PC/104 configuration that eliminates the need for a costly motherboard. Connections between the modules are made with plug-together on-board connectors that are environmentally rated for industrial service in adverse conditions.

GAPTM Graphical Application Programmer
[Block-format Application Software]
Woodward's Graphical Application Programmer (GAPTM) is a Windows based software program that allows controls engineers to create block format application programs for a number of Woodward control systems. Once the control logic is entered using the program's graphical programming environment, the GAP software compiler function generates code that runs in the control. GAP software blocks are written in C code, which is a transportable language, allowing it to be used on many different hardware platforms. Because of this feature, the same control logic software that has been used and proven in thousands of controls is available for use in the creation of future controllers, without introducing system bugs. Learn more from GAP product spec 03216.
Monitor GAPTM Graphical Application Programmer
[View & Edit Runtime Values]
Monitor GAPTM is a licensed software service tool that allows service personnel to view and edit runtime values for GAP (Graphical Application Program) generated application software. GAP software is Woodward's pictures-to-code programming tool. This programming system uses libraries of control objects that are connected together in a graphical format. The final control design is displayed as a group of interconnected blocks that represent the actual functionality of the code running in the control hardware. Monitor GAP works in parallel with the GAP graphical display and superimposes the actual runtime values on that display. The user is then able to see directly all control values-true/false for Boolean variables and numeric values for real or integer variables. In addition, Monitor GAP can edit variables that have been previously declared as 'tunable' in the original GAP design. The basic GAP editor includes Monitor GAP within its core structure. As such, Monitor GAP software need only be activated by installation of the GAP Editor/Monitor software and license authorization of the Monitor GAP features. Learn more from Monitor GAP product spec 03306.
NetSimTM Software
[GAP Simulation Tool]
NetSimTM software provides a powerful simulation environment for Woodward's GAPTM software. NetSim software produces a virtual test stand in the office or in the field. Without hardware in the loop, the engineer performs dynamically accurate simulations. "Time" is controlled by the modeling software, giving the user complete control of program execution to thoroughly test and analyze control code.
