Communication Protocols

A Chap­ter of the

IEC 60870–5 is a pro­to­col stan­dard for tele­con­trol, telepro­tec­tion, and oth­er telecom­mu­ni­ca­tion func­tions for elec­tric pow­er systems.

IEC 60870–5‑104 (short IEC104) is a com­pan­ion stan­dard defin­ing how to extend the IEC 60870–5‑101 pro­to­col to gain net­work access using stan­dard trans­port profiles.

DLMS/COSEM (or IEC 62056) is the main glob­al stan­dard for smart ener­gy meter­ing, con­trol and man­age­ment. It includes spec­i­fi­ca­tions for media-spe­cif­ic com­mu­ni­ca­tion pro­files, an object-ori­ent­ed data mod­el and an appli­ca­tion lay­er protocol.

Mod­bus is a com­mu­ni­ca­tions pro­to­col based on master/slave (RTU) or client/server (TCP/IP) archi­tec­tures that can oper­ate on the 1st, 2nd, 7th lev­el of the OSI Model.

Orig­i­nal­ly designed in 1979 by Mod­i­con for its range of PLCs, it is now a de fac­to stan­dard com­mu­ni­ca­tions pro­to­col in the indus­try, becom­ming the most wide­ly avail­able pro­to­col for the con­nec­tion of indus­tri­al elec­tron­ic devices.

Dis­trib­uted Net­work Pro­to­col 3 (DNP3) is a set of com­mu­ni­ca­tions pro­to­cols used between com­po­nents for automa­tion sys­tems in elec­tric, indus­tri­al and water sectors.

It is a key pro­to­col in SCADA sys­tems, where it is pri­mar­i­ly used for com­mu­ni­ca­tions between a mas­ter sta­tion and RTUs or IEDs.

ICCP (Inter-Con­trol Cen­ter Com­mu­ni­ca­tions Pro­to­col) is a stan­dard pro­to­col for com­mu­ni­ca­tions between con­trol cen­ters, which is part of the IEC 60870–6 stan­dard under the name of TASE.2 Tele­con­trol Appli­ca­tion Ser­vice Ele­ment 2.

It is being used around the world to exchange data over wide area net­works (WANs) between grid oper­a­tors, util­i­ties, vir­tu­al pow­er plants, region­al con­trol cen­ters and oth­er generators.

PROFIBUS (Process Field Bus) is an open stan­dard for field­bus com­mu­ni­ca­tions in indus­tri­al automa­tion sys­tems that was first pro­mot­ed in Ger­many in 1989.

The now most com­mon­ly found “Profibus DP” pro­vides sim­ple com­mu­ni­ca­tions between Profibus mas­ters and their remote I/O slaves.

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.

Smart Metering

A sin­gle device that col­lects, process­es, trans­fers smart meter data and load curves from sev­er­al meters in dif­fer­ent pro­to­cols via ser­i­al or Eth­er­net, whilst pro­vid­ing advanced automa­tion func­tions? Adapt­able designs and a full com­mu­ni­ca­tion pro­to­col suite make it possible.
