In keeping with the above requirements and considering the findings of the Current
Applications of KNX Logging section (p. 10), having a separate logging service and user interface seems the most logical solution. Separating the GUI and the logger would allow for the KNX bus to be logged with a background process, rather than require an application to be running in the foreground when logging.
Figure 2.3-1 illustrates the overall solution proposed in this section. The diagram shows the KNX network, the KNX to serial module, the host server, the logging service, the database, the user interface and finally the user; it illustrates how these components of the logger system will interact with each other.
In this proposal, a basic KNX network has been developed with various actuators and sensors. The sensors are more important in the example network as these are the modules from which the telegrams to be recorded originate. The KNX bus has a KNX to PC module which connects the KNX network to a computer, these sorts of module will be discussed in greater depth later but generally are used to connect a KNX network to another device via USB in order to configure or otherwise manipulate the KNX network.
The KNX to PC module connects the KNX network to a server. The server hosts the logging service which is used to record all information on the KNX bus in a data store. In Figure 2.3-1 the data store is shown to be hosted on the server as well, however this is something which may
This C6713 DSK board not only can communicate with different kinds software such as MATLAB/Simulink or Code Composer Studio software tool but also is supported by them through an embedded JTAG emulator with a USB host interface. Figure 1.2 represents the TMS320C6713-based DSK board.
Module 1 establishes the framework of networking standards and protocols for the rest of the class. The module introduces data communications and defines their components and the types of data exchanged. You will learn how different types of data are represented and how data is flowed through the network.
In the design, the topology used is a star topology. The computers in every office or classroom are linked to the central device known as the switch. The star topology leads to the expansion of the network without any disruption. This defines the use of a hub, a router or a switch to interconnect various computers together. All the workstations in this topology are connected with a connection of point-to-point to the central device. The data is first passed through the primary device before reaching the planned destination. Hub controls and manages the whole network. The hubs connect several nodes that are present in the star system. The hub acts as the signal booster (Elhakeem, 2010).
In order to implement the data measurement, storage, and actuation, communication paths must be set up between the sensors, actuators, processor, and storage. The communication paths use communication standards such at HTTP and Zigbee and custom protocols such as the protocol between the Gateway and Sensor Modules. The primary goal of these protocols is reliable communication. Each protocol uses acknowledgements to ensure the validity of the data. Using these protocols approximately 3.3KBytes are sent from the Sensor nodes to the Gateway per hour and approximately 1.3KBytes are sent from the Gateway and the Sensor nodes. This is a low date rate system designed to save power. Although the system network usually functions well there are noise levels with
This configuration is the most flexible of those described, since it allows to connect the unit to the Internet and automatically download its historian data to a remote server. No particular configuration is required in this case since the only requirement is that the remote unit is configured with the fixed IP of the central server and can freely connect to the internet. This can be obtained, if the unit cannot be configured inside the plant network, by using a wireless 3G/4G adaptor which directly allows a connection to internet. The remote replication of data requires to implement a central data server to receive the data. This server should be installed either in Sea Marconi Head quarter or can be part of the client network. The cost of

A set of preliminary usage scenarios that describe the use of the system under different operating conditions.
With this in place Kudler will keep using the ANSI standards when designing and developing the new systems. Along with these standards the system will need to work on a common communication protocol in order for all devices to be able to talk to each other as well as transfer data and other information correctly and efficiently.
It transmits mouse and keyboard actions from one computer to another to allow technical support personnel to operate server, desktop or other device via network as it is more efficient than to guide users through the whole procedure over the phone or to have the technical support personnel to be physically at the workstation.
This section gives the details and specification of the hardware on which the system is expected to work.
Data will be created and used from all work stations on the network. The data will be produced by software application in a windows 7 environment on all work station and windows server 2008 on the server. Office 2010 professional (word, excel, power point, access and outlook) will also be utilized. Other data sources to be supported will be windows 7 accessories. The network cannot be accessed from outside the facility.

RapidLog is the system where the drivers enter the diving information and this system calculates everything for them. According to Scott, this system cannot be falsified.
Technology has streamlined fleet management in a variety of ways, and continues to do so. Most fleets are dependent on their GPS tracking devices to determine location of their assets, vehicles, and personnel. Fleet managers are now able to view their business operations remotely, and are thus able to monitor and track every vehicle in their fleet, always, no matter where they are. This capability, alone, has resulted in increased production, reduced waste, money saved, and happier customers. The GPS remote tracking ability is provided through an application program interface (API). Remote tracking is just one of the reasons why you need an application program interface.
