SCADA System Assessment EPG Companies Inc. This article offers a basic overview of SCADA telemetry network system information. It is intended to help educate and equip you for future SCADA andor telemetry system decisions. Supervisory Control and Data Acquisition SCADA is a system that allows an operator at a master facility to monitor and control processes that are distributed among various remote sites. A properly designed SCADA system saves time and money by eliminating the need for service personnel to visit each site for inspection, data collectionlogging or make adjustments. Real time monitoring, system modifications, troubleshooting, increased equipment life, automatic report generating. SCADA system. These and other costly mistakes can be avoided through knowing, understanding, and carefully assessing your particular needs.

We have served the industry for over 2. A BRIEF HISTORYThe development of SCADA can be traced back to the early 1. Telemetry involves the transmission and collection of data obtained by sensing real time conditions. The monitoring of remote conditions became possible with the convergence of electricity, telegraph, telephone, and wireless communication technology. Throughout the last century, more industries, such as gas, electric, and water utilities, used telemetry systems to monitor processes at remote sites. SCADA began in the early sixties as an electronic system operating as InputOutput IO signal transmissions between a master station and a Remote Terminal Unit RTU station. Scada Pdf FileThe master station would receive the IO transmissions from the RTU through a telemetry network and then store the data on mainframe computers. In the early seventies, DCS Distributed Control Systems were developed. SCADAhacker provides professional services designed at securing the control systems which control our critical infrastructure. The ISAS5. 1 standard defines a distributed control system as a system that while being functionally integrated consists of subsystems, which may be physically separate and remotely located from one another. Large manufacturers and process facilities utilized DCS primarily because they required large amounts of analog control. Introduction. The M650 family of multifunction SCADA meters provides a range of measurement and communications capabilities for 3phase metering. Executive summary This white paper discusses the various components found in a typical Remote SCADA System, the operational challenges inherent in these types of systems. SIMATIC WinCC is a supervisory control and data acquisition SCADA and humanmachine interface HMI system from Siemens. SCADA systems are used to monitor and. Further development enabled Distributed Control Systems to use Programmable Logic Controllers PLC, which being more intelligent than RTUs, have the ability to control sites without taking direction from a master. In the late nineties, the differences between SCADA and DCS blurred. SCADA systems had DCS capabilities. DCS had SCADA capabilities. Systems were customized based on certain control features built in by designers. Now with the Internet being utilized more as a communication tool, control functions that were once old telemetry systems are becoming more advanced, interconnected and accessible. Scada Pdf Books' title='Scada Pdf Books' />Automated software products are being developed to exploit the inter connectivity of the Internet and certain portals can connect to a SCADA system and download information or control a process. Good SCADA systems today not only control processes but are also used for measuring, forecasting, billing, analyzing and planning. Todays SCADA system must meet a whole new level of control automation, interfacing with yesterdays obsolete equipment yet flexible enough to adapt to tomorrows changes. Whether you need a new system or are upgrading an older one, it is important to know the system components before you decide on who to talk with and what equipment you will need for your particular application.

SCADA Software. 1. Master Terminal Unit MTUThe Master Terminal Unit is usually defined as the master or heart of a SCADA system and is located at the operators central control facility. The MTU initiates virtually all communication with remote sites and interfaces with an operator. Data from remote field devices pumps, valves, alarms, etc. MTU to be processed, stored andor sent to other systems. For example, the MTU may send the data to the operators display console, store the information, and then send an operators initiate command to a field pumps RTU. Remote Terminal Unit RTUThe Remote Terminal Unit is usually defined as a communication satellite within the SCADA system and is located at the remote site. The RTU gathers data from field devices pumps, valves, alarms, etc. MTU initiates a send command. CR/NV/MY-2312688/scada-supervisory-control-and-data-acquisition-abb-make-500x500.jpg' alt='Scada Pdf Ebook' title='Scada Pdf Ebook' />Some RTUs are designed with microcomputers and programmable logic controllers PLCs that can perform functions at the remote site without any direction from the MTU. In addition, PLCs can be modular and expandable for the purpose of monitoring and controlling additional field devices. Within the RTU is the central processing unit CPU that receives a data stream from the protocol that the communication equipment uses. The protocol can be open like Modbus, Transmission Control Protocol and Internet Protocol TCPIP or a proprietary closed protocol. When the RTU sees its node address embedded in the protocol, data is interpreted and the CPU directs the specified action to take. During the sixties, many manufacturers developed RTUs with communicative functions that performed a few specific tasks such as monitor and control digital and analog field devices. These all in one RTUs needed constant communication with the MTU in order to operate. 4Th Edition Technology Brewing And Malting. A wide variety of programming languages were used that were not well known or supported. In the eighties the first micro PLCs were introduced as the first Open Architecture technology which has evolved and gained acceptance as todays preferred alternative to closed, proprietary systems. Some manufacturers, like EPGs SCADA division NBT, now make Remote Access PLCs RAPLC specifically designed for SCADA and Data Acquisition applications. With NBTs PLC system, you can Perform control. Check site conditions. Re program anytime from anywhere. Have any alarm or event trigger a call to your personal computer. This can all be done from a single, master site and the system can control one or multiple sites. Both industry representatives and customers welcome these smart PLCs because they provide remote programmable functionality while retaining the communications capability of an RTU. Communication Equipment. The way the SCADA system network topology is set up can vary with each system but there must be uninterrupted, bidirectional communication between the MTU and the RTU for a SCADA or Data Acquisition system to function properly. This can be accomplished in various ways, i. This may include dial up or dedicated voice grade telephone lines, DSL Digital Subscriber Line, Integrated Service Digital Network ISDN, cable, fiber optics, Wi. Fi, or other broadband services. There are many options to consider when selecting the appropriate communication equipment and can include either a public andor private medium. Public medium is a communication service that the customer pays for on a monthly or per time or volume use.
