SCADA — Supervisory Control and Data Acquisition

What is SCADA?

SCADA — Supervisory Control and Data Acquisition

Super­vi­so­ry con­trol and data acqui­si­tion (SCADA) sys­tems col­lect, mon­i­tor and process real-time data to:

  • Auto­mate and con­trol indus­tri­al process­es remote­ly or locally
  • Pro­vide a human-machine inter­face (HMI) to direct­ly inter­act with devices such as relays, sen­sors, gen­er­a­tors, pumps, valves and others
  • Record events and auto­mate reporting
  • The SCADA soft­ware process­es, allo­cates and dis­plays the data to sup­port oper­a­tors in their deci­sions and reports infor­ma­tion  such as fail­ures, alarms or per­for­mance data. to sev­er­al actors.
  • The com­mands send through the SCADA by the oper­a­tor are com­mon­ly exe­cut­ed on-site from a sin­gle access point via remote con­trol units (most com­mon­ly RTUs/gateways, some­times PLCs).
  • RTUs are com­put­ers that can com­mu­ni­cate with a range of devices in the facil­i­ty, includ­ing meters, HMIs, IEDs, sen­sors and many oth­ers. They route the data they col­lect from these object to the servers run­ning the SCADA software.

    RTU most com­mon­ly stands for Remote Ter­mi­nal Unit, but is some­times also used as an abbre­vi­a­tion for Remote Teleme­try Unit or Remote Tele­con­trol Unit.

    RTUs are devices that rely on micro­proces­sors and com­mu­ni­ca­tion inter­faces to auto­mat­i­cal­ly mon­i­tor and con­trol field devices and estab­lish a bridge to the plant con­trol or SCADA (super­vi­so­ry con­trol and data acqui­si­tion) systems.

    • Record events and auto­mate reporting

    An Intel­li­gent Elec­tron­ic Device (IED) is a term used in the elec­tric pow­er indus­try to describe micro­proces­sor-based con­trollers of pow­er sys­tem equip­ment, such as cir­cuit break­ers, trans­form­ers and capac­i­tor banks.

    Sequence of events record­ing (SER) is per­formed by micro­proces­sor based sys­tems, which mon­i­tor col­lect­ed data inputs and record the time and sequences of the changes.

    Sequence of events recorders rely on exter­nal time sources such as GPS or radio clocks to record the exact time of state of each change.

    SCADA & iGrid

    Our iCon­trol SCADA solu­tions has been around as long as the com­pa­ny itself.

    As the cen­tral piece of our exper­tise, it unites most of our soft­ware’s func­tion­al­i­ties and capa­bil­i­ties and con­tin­ues to grow every year.

    iControl SCADA

    High-per­for­mance SCADA for the visu­al­iza­tion and con­trol of sub­sta­tion data. It is able to run either in client/server or stand­alone modes, pro­vid­ing advanced func­tion­al­i­ties such as hot-stand­by redun­dan­cy, auto­mat­ic line col­or­ing, events noti­fi­ca­tion (via e‑mail and sms), SQL log­ging, and reports generation.

    iGW‑S Substation Gateway

    Pow­er­ful and reli­able sub­sta­tion gate­way, able to run either in stand­alone or redun­dant modes, with an embed­ded Eth­er­net switch (4 ports) and IEC 61850 client and serv­er capabilities.

    iGrid Solutions and Applications

    Automation with IEC 61850 

    The IEC 61850 stan­dard is enabling new opor­tu­ni­ties for ven­dor inter­op­er­abil­i­ty and advanced sub­sta­tion automa­tion. Find out how you can take advan­tage of IEC 61850 with easy-to-use and adapt­able solu­tions for a sim­ple migra­tion or retrofit.

    HV Substation Automation

    Pow­er­ful sub­sta­tion automa­tion sys­tems often han­dle numer­ous com­mu­ni­ca­tion pro­to­cols and media with­in one net­work, which can result in expen­sive and com­plex projects.  Avoid these prob­lems with inter­op­er­a­ble tech­nol­o­gy and smart con­fig­u­ra­tion tools.
