Project Design

In this paper is an explanation of the design process of the problem with which I was faced in the previous paper. Each phase of the project was carefully analyzed and planned accordingly to assure project success. The project involves the purchasing and installation of digital controllers and also implementation into the already existing system.

Design

In order to finish the project successfully, more digital controllers needed to be purchased and also a license for Windows Server 2003. The new controllers will hold more data points and the Windows Server 2003 operating system is required by the controllers in order to get maximum usage and compatibility. The ultimate goal is to have these controllers stor their data point in the servers' database and call upon them when needed for any specific process. Below is a diagram of what the system should represent:

With all of the points residing on the server, it leaves the controllers memory open to perform the recent processes. This will result in faster processes, and less time it takes to process multiple tasks. In the industry, it is often sought after to multi-task and increase productivity. So in the design phase of the project, it is always thoughtful to apply this when planning.

Process

The process used when designing this system was lead by end-user thoughts. The customer is always the most important when designing a project, and usually the customers thoughts are very intuitive and respectful because they are the people who will be using this new system. Although the system is almost fully automatable by internal programming within the controller, the end-user has a workstation in which they can see what is going in within the facility. The operator workstation will also be used to override or manually configure the controllers to perform other tasks described by the user. Each user will need a username and password in order to make adjustments. The user will only have certain permissions which are given to them by their supervisor, or are setup when the implementation of the system begins.

Network

The design utilizes a local area network that is also connected to the internet. This network must be secure because it
