The process of building a real time distributed control network involves many tasks. Some of these tasks include writing the application program for each controller and downloading that program into the controller's memory for execution. Typically, each program includes some standard modules, such as the hardware interface modules and the algorithm that represents the control strategy. Visual Control, for Windows 95 and NT, is a graphical development system that automates the process of building distributed LonWorks control networks. Visual Control can be thought of as a CASE (Computer Aided Software Engineering) tool which enables users to draw control strategies and download them to controllers/nodes over the network with the push of a few buttons. It also provides network management capabilities such as installing nodes and connecting network variables.
Connect the Blocks…
The user adds all the needed devices into the node window and then connects their inputs and outputs in an electrical circuit fashion. The purpose of the connections is to define how devices in a particular node interact and exchange information. Each device can be configured to behave in a certain fashion and execute based on a time slice defined by the user. The user also gets to define the types of inputs and outputs of a device, their class (constant, local, or network), and their initial value. The IEC1131-3 programmable controllers international standard has been followed closely in implementing these devices. In some cases, Visual Control users may need to create control strategies that can not be implemented using built in devices. Therefore, Visual Control provides users a mechanism to create their own devices (i.e., user defined devices). Once these devices are defined, they can be used the same way as built in devices.
Just a few Clicks…
Visual Control graphically automates the process of writing the application programs, downloading them into their targeted nodes, installing the nodes, and connecting network variables. It enables the user to perform these tasks with the push of a few buttons and virtually without writing any code. Nonetheless, Visual Control is still independent of the actual hardware implementation of the controllers used in the network. These hardware specific elements can be implemented using special devices.
Draw the Strategy!
Visual Control makes the task of distributing control among many controllers easier and automated.
The user starts by drawing a strategy instead of writing a Neuron C program. A library of pre-built control functions, each represented by a device in Visual Control, has been provided. This allows the user to concentrate on developing the strategy, rather than writing the code for a PID loop or debugging a Lead Lag function.
Visualise the WHOLE strategy
Visual Control allows users to visualise the whole structure of the control network. This is because each node is represented by a window in a multiple document interface environment as shown in figure 1 below. Therefore, the maintenance of the control process becomes as easy as starting Visual Control, loading a project, modifying a node file, and rebuilding that node.  VisualControl
