What is the ICCP orTASE.2 protocol?
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 Element2.
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 OSImodel.
- 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 60870–5 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 theIEC 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 OSIModel.
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 isprimarily used for communications between a master station and RTUs orIEDs.
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 Element2.
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 in1989.
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.
The Slimmest Gateway
The iGWlite comes with 1Ethernet, 1 RS485/RS422 and an optional RS-232 port (copper or fiber) or a 2G/3G/4G mode– taking little space on a DIN-Rail, but still employing the full iGrid protocolstack.
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.
iRTU – With I/Os for Direct Data Acquisition
Compact and scalable bay controller which can act asIEC 61850 client or server, featuring configurable I/O boards for direct data acquisition, high-precision timestamping and an optional Ethernet switch for additional Ethernetports.
