iRTU – The Best Controller for Your SCADA

Why use a com­mon PLC, when you can have a mod­u­lar RTU made for sub­sta­tion environments?
  • Secured, adapt­able and mod­u­lar Remote Tele­con­trol Units suit­able for all envi­ron­ments and pow­er dis­tri­b­u­tion systems
  • Advanced func­tion­al­i­ties such as load shed­ding, microsec­ond time­stamp­ing, PRP redun­dan­cy or PLC automa­tion with IEC 61131–3   
  • Full range of pro­to­cols (DNP3.0, IEC 61850, IEC 60870–5… ) to com­mu­ni­cate with all devices and con­trol cen­ters con­nect­ed to your elec­tri­cal network.
  • Embed­ded Eth­er­net switch with (2) 10/100 BaseTx, (2) FX100 fiber optics and RSTP/ PRP/ HSR redun­dan­cy
  • Up to 4 Eth­er­net ports, 4 ser­i­al ports, and option­al, inter­nal 4G, 3G and GPRS modems

Our secure and scal­able RTUs can simul­ta­ne­ous­ly han­dle old­er (e.g. Mod­bus) and new­er (e.g. IEC 61850) pro­to­cols on ser­i­al, wire­less and Eth­er­net net­works — mak­ing sub­sta­tion automa­tion less com­plex and more affordable.

Remote tele­con­trol units (RTUs) for SCADAs are fre­quent­ly employed as bay con­trollers for data acqui­si­tion in sub­sta­tions, often requir­ing fur­ther devices for gate­way and more advanced func­tion­al­i­ties like load shed­ding or microsec­ond time­stamp­ing. Our mod­u­lar iRTUs are pow­er­ful con­trollers with embed­ded eth­er­net switch­es, state-of-the-art fea­tures and inter­nal I/Os, allow­ing you to do it all with one small device.

They can map ser­i­al servers to IEC 61850 log­i­cal nodes, col­lect and process data from old and new IEDs, report direct­ly to the cotrol cen­ter with any stan­dard pro­to­col (e.g. IEC 60970–5‑104, DNP3) and han­dle all com­mon pro­to­col con­ver­sions: Mod­bus to IEC 61850, IEC 101 to IEC 104, Mod­bus RTU to Mod­bus TCP, Mod­bus to Eth­er­net IP (Ser­i­al to Eth­er­net in gen­er­al), IEC 103 to DNP3 and many more.

A net­work archi­tec­ture based on iRTUs is open and scal­able: you can eas­i­ly inte­grate future gen­er­a­tions of devices (IEDs, sen­sors, routers etc.) and adapt to any present and future needs, such as chang­ing the net­work topol­o­gy or com­mu­ni­ca­tion media.

Technical Features

Communication Ports

The iRTU comes with 2 inde­pen­dent 10/100 BaseTX Eth­er­net ports (two dif­fer­ent MAC address­es, RJ45 con­nec­tor) and an inter­nal Eth­er­net switch with (2) 10/100BaseTX, (2) fiber optic FX100 sen­sors with ST, SC o SFP con­nec­tors, and RSTP /PRP /HSR redundancy.

Addi­tion­al­ly, the iRTU car­ries 4 soft­ware con­fig­urable ser­i­al ports: 1 full RS-232/RS-485/RS-422 + 2 basic RS-232/RS-485/RS-422 and 1 RS-422/RS-485 port (EXP422) to con­nect iRTUe mod­els. Option­al­ly, one of the ser­i­al ports can be replaced with an inter­nal 4G(LTE), 3G and GPRS modem.

Time Management

The iRTU man­ages a broad range of time syn­chro­niza­tion meth­ods with fault tol­er­ant pri­or­i­ty schemes (NTP, IEEE1588/ PTP, IEC60870‑5–101, DNP 3.0) to ensure that your net­work is syn­chro­nized and you can retrace any net­work failures.

The time stamp accu­ra­cy of the iRTU is supe­ri­or to one 1ms and has a 1 microsec­ond res­o­lu­tion. In case the time serv­er fails, the iRTU can rely on its high accu­ra­cy real time clock (1.5ppm) as a back­up. 

IEC61131‑3 PLC Automation

Thanks to its inter­nal PLC based on IEC 61131–3, the iRTU can pro­vide pow­er­ful automa­tion and con­trol func­tion­al­i­ties.
For exam­ple, you can eas­i­ly reuse pro­grams on dif­fer­ent projects, run mul­ti­ple PLC instances simul­ta­ne­ous­ly or use trig­gered vari­ables for con­trol com­mands and set points. It also allows to run hot pro­gram updates, stop PLC exe­cu­tions depend­ing on the qual­i­ty of select­ed PLC inputs and debug PLCs online, either cycle-by-cycle or step-by-step.

The iRTU has a high exe­cu­tion speed – a 2000 ST line pro­gram takes less than 3ms.

Standards and Compliance

The diverse back­grounds of our part­ners and clients from all over the world have helped us gath­er state-of-the-art know-how and first­hand expe­ri­ence in a great vari­ety of ener­gy appli­ca­tions. This joined knowl­edge is the foun­da­tion of our opti­mized iRTU/GW fam­i­ly, which has a proven track record of being par­tic­u­lar­ly effec­tive and resis­tant for a diverse range of appli­ca­tions and harsh envi­ron­ments belong­ing to the ener­gy industry.

As a result, the iRTU meets the require­ments of exten­sive stan­dards, such as IEC61850‑3, IEC60870‑2–1 & IEC60255-26.

Protocols & IP Networking

The iRTU was designed to use a high num­ber of pro­to­cols (see data sheet) and com­mu­ni­cate with sev­er­al con­trol cen­ters at once. It is equipped with trans­par­ent TCP bridg­ing and con­fig­urable IP rout­ing to tun­nel any ser­i­al pro­to­col (such as Mod­bus) over a TCP/IP con­nec­tion and facil­i­tate the con­trol of com­plex IP networks.

The iRTU IEC 61850 capa­bil­i­ties have been A lev­el cer­ti­fied by DNV-KEMA. 

Inputs and Outputs

iRTUs are equipped with inter­nal I/O mod­ules for direct data acqui­si­tion and fea­ture a 2.5kV iso­la­tion. The DIs can be cho­sen in 4 volt­age lev­els (or cus­tomized) and grant a 1 ms time­stamp accu­ra­cy. Each input can also be defined as a counter and pro­vide indi­vid­u­al­ly con­fig­urable debounce and declut­ter­ing fil­ters. Its AIs have a cur­rent range of ±20 mA (oth­er volt­ages and cur­rents upon request) and a 0.15% accuracy.

The iRTU also offers inter­nal dry con­tact electro­mechan­i­cal relay out­puts in sev­er­al rat­ings and with an iso­la­tion of 6 kV.

    HV Substation RTU

    In this project, the iRTU-B0C1 reads the meter­ing data from meter­ing IEDs (trans­ferred through an RS485 bus) via Mod­bus RTU and pass­es the data to a local util­i­ty as well as to a local oper­a­tor, who is in charge for the MV section.

    PV Plant Controller

    In this project, the iRTU is used to remote­ly con­trol and super­vise over 100 pho­to­volta­ic gen­er­a­tion plants around Turkey. At each PV plant, one iRTU gath­ers the data with a 1ms time accu­ra­cy from dozens of invert­ers (via Mod­bus­R­TU), meters (via IEC 62056–23), and pro­tec­tions relays (via IEC 61850) and trans­fers the data via IEC60870‑5–104 through GPRS (secured VPN con­nec­tion) to the con­trol cen­ter, where it’s stored on an SQL database.

    HV Substation Automation

    In this project, the iRTUs con­trol meters and pro­tec­tion relays from dif­fer­ent man­u­fac­tur­ers (ABB and Siemens) using com­mu­ni­ca­tion pro­to­cols like Mod­bus and DNP3.0. The data col­lect­ed from the IEDs (meters and pro­tec­tion relays) is sent to the con­trol cen­ters via DNP3.0.

    iRTUe – Remote I/O Extensions 

    iGWs, iRTUs and third par­ty mas­ter units can be freely extend­ed by con­nect­ing one or sev­er­al iRTUe.

    They are IEC 61850 (GOOSE) com­pli­ant and come in many con­fig­u­ra­tions such as 48 DI, 16 relays, 16 AI, 24 DI + 8 relays, 24 DI + 8 AI or 8 relays + 8 AI.

    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.
