Communication Protocol Converters & Gateways

From Mod­bus­R­TU to IEC 61850 — unlock new poten­tial with state-of-the-art pro­to­col conversion

What is a Protocol Gateway?

Pro­to­col gate­ways, also known as pro­to­col con­vert­ers or trans­la­tors, are small devices that main­ly func­tion as trans­la­tors between var­i­ous pro­to­cols and phys­i­cal lay­ers (i.e. Eth­er­net and ser­i­al lines). They allow to con­trol and com­mu­ni­cate with machin­ery such as intel­li­gent elec­tron­ic devices, sen­sors and com­put­ers  in order to oper­ate indus­tri­al facil­i­ties such as dams, sub­sta­tions, pow­er plants, and water pro­cess­ing facil­i­ties. Since numer­ous devices par­tic­i­pate in one process or func­tion, but often come from dif­fer­ent ven­dors, com­mu­ni­ca­tion lay­ers and pos­si­bly appli­ca­tion areas, the devices are not able to com­mu­ni­cate with each oth­er and a pro­to­col con­vert­er is required to con­vert the data into the right for­mat. Even though indus­tri­al automa­tion sys­tems have been tran­si­tion­ing from pro­pri­etary pro­to­cols towards stan­dard com­mu­ni­ca­tion pro­to­cols, the grow­ing com­plex­i­ty of the super­vised sys­tems has kept gate­ways as cen­tral ele­ment in all kinds of com­mu­ni­ca­tion networks.

Fur­ther­more, the ongo­ing trend of intro­duc­ing IoT in indus­tri­al envi­ron­ments presents fur­ther inter­op­er­abil­i­ty chal­lenges due to the bridge between ser­i­al-based oper­a­tional tech­nol­o­gy (OT) and infor­ma­tion tech­nol­o­gy (IT), com­mon­ly using Eth­er­net, Wifi or GPRS networks.

  • Col­lect and con­cen­trate mul­ti-ven­dor meter­ing data and load curves through mul­ti­ple pro­to­cols through IEC60870‑5–102, IEC 62056–21, Mod­bus or DLMS and trans­fer it to con­trol centers
  • Inter­nal PLC based on IEC 61131–3 for sig­nal pro­cess­ing, advanced automa­tion func­tions and log­i­cal schemes
  • Inter­nal mem­o­ry and advanced net­work redun­dan­cy based on RSTP, HSR and PRP (IEC 61850) for high­er data reli­a­bil­i­ty and main­te­nance work.

Protocol Conversion and Network Gateways

One of the major chal­lenges with com­mu­ni­ca­tion net­works in elec­tric and indus­tri­al facil­i­ties is the inte­gra­tion of new sub­sta­tion tech­nol­o­gy in old­er net­works, where old and new devices have to coex­ist and com­mu­ni­cate with each oth­er. Exam­ples of this can be new con­trol cen­ters that have to com­mu­ni­cate with old automa­tion sys­tems or new­ly installed intel­li­gent elec­tron­ic devices (IEDs), which must con­nect to old sys­tems in the net­work or the con­trol center. 

Anoth­er com­mon chal­lenge is com­mu­ni­ca­tion accross mul­ti­ple lay­ers (e.g. from Mod­bus RTU to Mod­bus TCP), spe­cial­ly when it involves sev­er­al com­mu­ni­ca­tion media, such as ser­i­al and Eth­er­net.

Solu­tions by iGrid T&D have been designed for exact­ly this kind of chal­lenges. Thanks to our com­mit­ment to stan­dard pro­to­cols, all devices devices and soft­ware sys­tems, com­pris­ing RTUs, gate­ways, I/O exten­sion units and SCADA sys­tem, pro­vide a unique range of com­mu­ni­ca­tion pro­to­cols and con­nec­tiv­i­ty options.

Our solu­tions can use almost all pro­to­cols to both col­lect and trans­fer data from and between devices and entities.

Amongst oth­ers, the sup­port­ed com­mu­ni­ca­tion pro­to­cols include:

Master/Slave IEC 60870–5‑101 Master/Slave IEC 60870–5‑104
Master/Slave Mod­bus TCP/UDP and JBUS (mas­ter) Master/Slave Mod­bus­R­TU
Master/Slave DNP3.0 (ser­i­al, UDP, TCP) Mas­ter IEC 60870–5‑103
Mas­ter IEC 60870–5‑102 Mas­ter DLMS
Mas­ter Profibus DP Mas­ter Spabus, Mlink, Procome
Mas­ter IEC 62056–21 SNMP Agent/Manager
IEC 61850 MMS Client/Server                 IEC 61850 GOOSE Publisher/Subscriber
OPC UA

 

Our solu­tions can also com­mu­ni­cate through tech­nolo­gies from oth­er indus­tries like mySQLweb ser­vices and IoT pro­to­cols (e.g. MQTT).

Fur­ther­more, the devices have com­mu­ni­cat­ed with equip­ment from numer­ous dif­fer­ent ven­dors in a broad vari­ety of appli­ca­tions. We have con­nect­ed it all: new and old sys­tems, Eth­er­net and ser­i­al, IEC 61850 and old lega­cy pro­to­cols (like SPA-bus), IoT net­works and old relays, SCADA sys­tems and intranets, gen­er­a­tion and ener­gy market. 

Our Gateways and Protocol Conversion Solutions

Since we believe in advanced automa­tion tech­nol­o­gy, all devices and soft­ware sys­tems by iGrid T&D can not only con­vert between sev­er­al pro­to­cols but also pro­vide an exten­sive range of func­tion­al­i­ties and char­ac­ter­is­tics to over­come present and future com­mu­ni­ca­tion chal­lenges in the most effi­cient ways.

With our state-of-the-art prod­ucts, you no longer need to wor­ry about inter­op­er­abil­i­ty and net­work inef­fi­cien­cies. 

Our devices are already con­fig­urable and ver­sa­tile by design, but we also pro­vide fur­ther prod­uct con­fig­u­ra­tions and tai­lored ser­vices upon request.

    Full Independence for an Open Architecture

    All of our prod­ucts sup­port sev­er­al types of com­mu­ni­ca­tion media, such as wire­less (GPRS/ 3g, 4g), VSAT, ana­log radio, Eth­er­net or Ser­i­al, and can com­mu­ni­cate with the entire iGrid T&D pro­to­col suite. Thanks to our expe­ri­ences with devices from almost all known ven­dors and our pledge for stan­dard pro­to­cols, we can ensure the seam­less inte­gra­tion of our prod­ucts with any third par­ty devices.

    Sleep Peacefully with Expert Cyber Security 

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

    Our hard­ened devices fea­ture 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.

    Hot-Standby Redundancy

    All of our devices can oper­ate in hot-stand­by redun­dan­cy mode:

    • Hot-stand­by server/device is updat­ed continuously
    • Clients and IEDs auto­mat­i­cal­ly switch to the hot-stand­by server
    • Ser­i­al loop redun­dan­cy (hot stand­by gate­way acts as a (vir­tu­al) ser­i­al port to arrive to dis­con­nect­ed devices)

    Network Redundancy

    All of our devices can pro­vide RSTP, HSR & PRP (IEC 62439–3) redundancy

    • Mod­ern sub­sta­tion automa­tion with­out pack­et loss­es and latencies
    • Invis­i­ble to the appli­ca­tion and usable by most indus­tri­al Eth­er­net protocols
    • For appli­ca­tions requir­ing high avail­abil­i­ty and quick switchovers
