iGW – Master of Protocols & Data Collection

Sub­sta­tion automa­tion, data con­cen­tra­tion, pro­to­col con­ver­sion, gen­er­a­tion con­trol.. you name it! The iGW is smart and high­ly adapt­able, solv­ing all of your net­work chal­lenges effi­cient­ly.

Our secure gate­way has been designed for par­tic­u­lar­ly strong pro­to­col con­ver­sion, net­work redun­dan­cy and SCADA automa­tion (incl. IEC 61850). It is thus the per­fect choice to set up, automize or retro­fit gen­er­a­tion plants, sub­sta­tions and oth­er con­trol net­works requir­ing data con­cen­tra­tion or con­ver­sion between sev­er­al pro­to­cols, as for instance Mod­bus to Eth­er­net or IEC 61850 to DNP3.

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, whilst man­ag­ing a microsec­onds time­stamp res­o­lu­tion via NTP or PTP. Fur­ther, the iGW can also process and trans­fer the data to one or mul­ti­ple con­trol cen­ters or SCADA mas­ter sta­tions using upstream pro­to­cols such as IEC 104, IEC 101, TASE2.0/ ICCP (IEC 60870–6), IEC 61850–90‑2, DNP3, and Mod­bus RTU/TCP.

A net­work archi­tec­ture based on iGWs is open, effi­cient and scal­able, as it allows to inte­grate com­ing gen­er­a­tions of devices (IEDs, sen­sors, routers etc.) and adapt to any kind of changes made to your pow­er dis­tri­b­u­tion net­work, sav­ing you lots of time and mon­ey.

Technical Features

Communication Ports

The iGW 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 iGW 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.

Hot-Standby Redundancy

In a hot-stand­by archi­tec­ture, the active iGW con­tin­u­ous­ly feeds the record­ed data to the redun­dant stand­by iGW to ensure that the new­ly active iGW has all the his­tor­i­cal infor­ma­tion (no data loss) when the switchover occurs.

If the active RTU detects that any IED is not able to com­mu­ni­cate, it tries to access the IED via the hot-stand­by RTU, which (in the case there was a con­nec­tion prob­lem) can pass the data to the active RTU, act­ing as a ser­i­al serv­er.

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.

Communication Protocols

The iGW 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 such as 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, where­as upstream pro­to­cols for con­trol cen­ters also include IEC 60870–5‑101/-104 or DNP3.0 serial/TCP.

IP Networking

The iGW 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 data trans­fer through com­plex IP net­works.

Its VLAN and VPN sup­port allow to improve the network’s per­for­mance, sim­pli­fy­ing its traf­fic man­age­ment, design and deploy­ment and also help­ing to secure com­mu­ni­ca­tions through par­tic­u­lar­ly haz­ardous net­works.

Cyber Security – IEC 62351

iGrid enforces sev­er­al lay­ers of secu­ri­ty mea­sures guid­ed by the propo­si­tions of the IEC 62531 stan­dard to pro­tect its devices from all kinds of threats.

The iGW 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 end-to-end encryp­tions via TSL/SSL, HTTPS, SSH and stan­dard pro­ce­dures for VPNs (e.g. Open­VPN), its com­mu­ni­ca­tion can also be secured with net­work con­trol meth­ods such as fire­walls, IP fil­ters, ACL or TCP port blocks.

iRTU – The iGW with Integrated I/Os

The iRTU is an intel­li­gent and scal­able bay con­troller with inter­nal and con­fig­urable I/O capa­bil­i­ties for direct data acqui­si­tion, pow­er­ful pro­to­col con­ver­sion (incl. IEC 61850), high-pre­ci­sion time­stamp­ing and an option­al embed­ded Eth­er­net switch.

iGWlite – The “Lite” Version of the iGW

The iGWlite comes with 1 Eth­er­net, 1 RS485/RS422 and an option­al RS-232 port (cop­per or fiber) or a 2G/3G/4G modem tak­ing lit­tle space on a DIN-Rail, but still employ­ing the full iGrid pro­to­col stack.

iGW-VM – For Unlimited Scalability on Any Device

For every­one who wants the the soft­ware func­tion­al­i­ties of the iGW, but has a preferred hard­ware or is look­ing for high scal­a­bil­i­ty with exist­ing devices, there is the iGW-VM. It can run on Lin­ux or Win­dows servers and pro­vides unique fea­tures and flex­i­bil­i­ty.

HV Substation Automation with IEC 61850

In this HV sub­sta­tion automa­tion project the iGW-S3 (Eth­er­net switch mod­el) enables the upgrade to IEC 61850, com­mu­ni­cat­ing with the Pro­come pro­tec­tion relays and map­ping all their infor­ma­tion (includ­ing sig­nals, alarms, mea­sures and com­mands) into IEC 61850 log­i­cal devices.

Smart Metering Protocol Converter

In this project the iGW was deployed by a major meter man­u­fac­tur­er in over 150 gen­er­a­tion plans, con­cen­trat­ing 8 high-end meters through DLMS as well as map­ping and send­ing the data to the con­trol cen­ter via the IEC60870‑5–104 and Mod­bus RTU.

Railway MV Substation Control

In this project the iGW con­verts from IEC 101 to IEC104 in order to com­fort­ably expand the SCADA sys­tem of the metro lines, using high tech­nol­o­gy switch­es and SDH equip­ment via Eth­er­net. The iGW con­trols the low pow­er sub­sta­tions (380 Volt­age grid) by read­ing the data from a SIEMENS PLC via IEC 101, map­ping it to IEC104, and send­ing it to the exist­ing SCADA Con­trol Cen­ter.

iRTUe – Remote I/O Extensions

iGWs and iRTUs can be freely extend­ed by con­nect­ing 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 is a high-per­for­mance SCADA for the mon­i­tor­ing and con­trol of data col­lect­ed in elec­tri­cal net­works, such as sub­sta­tions, MV grids, pow­er plants or rail­way sys­tems. It is able to run either in client/server or stand­alone mode, han­dles most pro­to­cols and pro­vides advanced func­tion­al­i­ties such as hot-stand­by redun­dan­cy, auto­mat­ic line col­or­ing, events noti­fi­ca­tion (via e‑mail and sms), SQL log­ging, or the auto­mat­ic gen­er­a­tion of reports.
