iRTUcompact – Feeder & Renewable Plant RTU

Per­fect for Feed­er RTU (FRTU) & renew­ables appli­ca­tions, pro­vid­ing I/O and gate­way capa­bil­i­ties in a com­pact device.
  • Smart and com­pact all-in-one RTUs (remote tele­con­trol units) spe­cial­ly suit­able for renew­able plants and dis­tri­b­u­tion feed­er automation.
  • Can pro­vide all com­mu­ni­ca­tion capa­bil­i­ties required for the con­trol of Pho­to­volta­ic plants
  • Offers mul­ti­ple com­mu­ni­ca­tion options incl. embed­ded Eth­er­net switch­es, built-in 4G/3G/GPRS modems, inter­nal I/Os and mul­ti­ple ser­i­al ports to com­mu­ni­cate with any device through any pro­to­col com­mon in the industry.

The iRTU­com­pact is an all-in-one device with inte­grat­ed I/O and numer­ous com­mu­ni­ca­tion ports to col­lect data from any pro­tec­tion relay or switchgear con­troller, mak­ing it the ide­al solu­tion for MV and gen­er­a­tion appli­ca­tions, specif­i­cal­ly Feed­er RTU (FRTU) and PV projects. 

Our secure and scal­able RTUs are equipped with an advanced com­mu­ni­ca­tion core to man­age, con­vert and trans­fer mul­ti­ple pro­to­cols on ser­i­al, wire­less and Eth­er­net net­works at once. They are also capa­ble of pro­vid­ing all required net­work­ing, redun­dan­cy and time syn­choniza­tion func­tions, allow­ing to auto­mate sub­sta­tions with few­er equip­ment, in a less com­plex and more afford­able way.

The data col­lec­tion from meters, pro­tec­tion relays, and oth­er IEDs can be per­formed using any pro­to­col, inl­cud­ing IEC 60870–5, IEC 61850 (MMS/GOOSE), DNP3, DLMS, Mod­bus or Pro­come, with a microsec­ond time­stamp res­o­lu­tion via NTP or PTP. 

An archi­tec­ture based on the iRTU­com­pact is open, effi­cient and scal­able, as it allows to inte­grate com­ing gen­er­a­tions of devices (IEDs, sen­sors, routers etc.) and adapt to any kind of net­work changes, sav­ing you lots of time and mon­ey.  With its inte­grat­ed dig­i­tal and ana­log I/Os, it can autonomosly report a high num­ber of data points from sev­er­al devices to upstream mas­ters and con­trol centers.

Technical Features

Communication Capabilities

Despite its small size, the iRTU­com­pact B mod­el comes with 2 inde­pen­dent 10/100 BaseTX Eth­er­net ports (two dif­fer­ent MAC address­es, RJ45 con­nec­tor) and 3 soft­ware con­fig­urable RS422/RS485/RS232 ser­i­al ports, while the S mod­el pro­vides three addi­tion­al Eth­er­net ports by replac­ing one of the con­ven­tion­al inter­faces with a switch.

The devices also car­ry 2 USB ports for con­fig­u­ra­tions and oth­er pur­pos­es. Option­al­ly, one of the ser­i­al ports can be replaced with an inter­nal 4G(LTE), 3G and GPRS modem.

IEC 61850 MMS

The iRTU­com­pact can be used as a sim­ple link between seri­al­ly con­nect­ed phys­i­cal devices and log­i­cal IEC 61850 devices, as it can map any sig­nal from many kinds of data mod­els and struc­tures onto IEC 61850 log­i­cal nodes, whilst also pro­vid­ing IEEE1588 / PTP time synchronization.

Thanks to its full iGrid pro­to­col stack, it can con­vert any stan­dard or lega­cy pro­to­col such as IEC 60870–5‑103, SPAbus, Mod­bus, DLMS to IEC61850, allow­ing it to com­mu­ni­cate with hun­dreds of vendors.

IEC61131‑3 PLC Automation

Thanks to its inter­nal PLC based on IEC 61131–3, the iRTU­com­pact 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 iRTU­com­pact has a high exe­cu­tion speed – a 2000 ST line pro­gram takes less than 3ms.

Communication Protocols

The iRTU­com­pact was designed to use a high num­ber of pro­to­cols and com­mu­ni­cate with sev­er­al con­trol cen­ters at once.

The stack includes new­er pro­to­cols such as IEC 61850 MMS or GOOSE (A‑level cer­ti­fied by DNV-KEMA), but also old­er stan­dard and pro­pri­etary pro­to­cols e.g. ModbusRTU/TCP, Profibus, SpaBus, Mlink or Pro­come. Oth­er sup­port­ed down­stream pro­to­cols for meters and pro­tec­tion relays are IEC 60870–5‑102/-103, IEC 62056–21 and DLMS, while upstream pro­to­cols for con­trol cen­ters also include IEC 60870–5‑101/-104 or DNP3.0 serial/TCP.

Digital & Analog In-/Outputs

The iRTU­com­pact pro­vides 24 dig­i­tal inputs (avail­able in 4 volt­age lev­els) with 2.5kVrms iso­la­tion and a 1 ms time­stamp accu­ra­cy as well as 4  high accu­ra­cy (0.15%) ana­log inputs (+/-20mA), two of which can be replaced with 2 PT100 tem­per­a­ture sen­sors. Each input can be defined as input or counter and pro­vide a con­fig­urable debounce filter.

On the out­put side, it pro­vides 8 dry con­tact elec­tro-mechan­i­cal relay out­puts with an iso­la­tion of 6kV.

Cyber Security

iGrid enforces sev­er­al lay­ers of secu­ri­ty mea­sures guid­ed by the propo­si­tions of the IEC 62351 stan­dard to pro­tect its devices from all kinds of threats.

The iRTU­com­pact is a hard­ened device fea­tur­ing Role Based Access Con­trol (RBAC) to avoid intrin­sic risks such as secu­ri­ty holes and unau­tho­rized actions by authen­ti­cat­ed users.

In addi­tion to encryp­tions via TSL/SSL, HTTPS, SSH and VPN sup­port (i.e. Open­VPN), its com­mu­ni­ca­tion can also be secured with net­work con­trol meth­ods such as fire­walls, IP fil­ters, ACL or TCP port blocks.

    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.

    iGW-VM – unlimited control

    The freely scal­able iGW-VM sup­ports all archi­tec­tures using Win­dows or Lin­ux, act­ing as a sub­sta­tion gate­way, bay con­troller, RTU or com­mu­ni­ca­tion front-end for SCADA sys­tems. The iGW-VM is thus the per­fect soft­ware choice for projects with a predetermined/preferred hard­ware or a large grid to cov­er (high num­ber of datapoints).

    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.
