SCADA systems have traditionally used combinations of radio and direct wired connections, although SONET/SDH is also frequently used for large systems such as railways and power stations. 0000001733 00000 n 0000004539 00000 n 6 Practical Troubleshooting and Problem Solving of PLCs and SCADA Systems Figure 1.5 The processor of a PLC (Courtesy: Allen-Bradley) The main processor (or CPU) is a microprocessor-based system that executes the control program, after reading the status of the field inputs. Whether single-user systems, multi-user systems, or even widely distributed systems: you can use Siemens SCADA systems to visualize machines, lines, and entire plants and thus ensure transparency. 0000002032 00000 n RTU / PLC Interface 6. SCADA systems are used to monitor and control the equipment in the industrial process which includes manufacturing, production, development, and fabrication. Practical Modern SCADA Protocols is a book that has been around for a while but is quite detailed and complete about the communication protocols in the SCADA system. Normal status Emergency status Restoration status .

Architecture Hardware Architecture One distinguishes two basic layers in a SCADA system: the "client layer" which caters for the man machine interaction and the "data server layer" which handles most of the Supervisory Control and Data Acquisition or simply SCADA is one of the solutions available for data acquisition, monitor and control systems covering large geographical areas. Understand the potential risks of Java-based HMI/SCADA versus solutions such as GE Digital's iFIX and CIMPLICITY HMI/SCADA… 0000039991 00000 n By default the SCADA system starts on the main screen, where the whole process is visualized. SCADA systems used to run on DOS, VMS and UNIX; in recent years all SCADA vendors have moved to NT and some also to Linux. Academia.edu no longer supports Internet Explorer.
