ICCP/ Tase.2 - Inter-Control Center Communications Protocol

What is the ICCP or TASE.2 protocol?

ICCP — IEC 60870–6/ TASE.2

ICCP (Inter-Con­trol Cen­ter Com­mu­ni­ca­tions Pro­to­col) is a stan­dard pro­to­col for com­mu­ni­ca­tions between pow­er grid con­trol cen­ters and 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.

  • ICCP allows to exchange real time and his­tor­i­cal data includ­ing sta­tus, mea­sured val­ues, sched­ul­ing data and oper­a­tor com­mands amongst others.
  • With ever increas­ing inter­con­nec­tiv­i­ty across inter­na­tion­al bor­ders and grid oper­a­tion zones, inter-util­i­ty real time data exchange has become crit­i­cal to the oper­a­tion of inter­con­nect­ed systems.
  • ICCP is a client/server based pro­to­col oper­at­ing at the appli­ca­tion lay­er in the OSI mod­el, sup­port­ing any inter­faces, trans­port and net­work ser­vices that fit the OSI model.
  • One con­trol cen­ter (client) sends a request to anoth­er con­trol cen­tre (serv­er) for the data to be exchanged., while both con­trol cen­ters may be both clients and servers.
  • TASE.2 is iden­ti­cal to ICCP and con­tains:
    IEC 60870–6‑503
    TASE.2 Ser­vices and pro­to­col
    IEC 60870–6‑602
    TASE trans­port pro­files
    IEC 60870–6‑702
    Func­tion­al pro­file for pro­vid­ing the TASE.2 appli­ca­tion ser­vice in end sys­tems
    IEC 60870–6‑802
    TASE.2 Object models

    Communication Protocols

    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. 

    ICCP & iGrid

    We have used ICCP for com­mu­ni­ca­tions with high­er lev­el con­trol cen­ter­sall over the world. In Spain, our dis­patch­ing and gen­er­a­tion con­trol cen­ters use ICCP to con­nect to the cen­tral­ized gen­er­a­tion con­trol cen­ters of red electrica.
