iGWlite – Smart, Slim and Simple.A compact data concentrator and protocol converter for substations and power plants
- Secured, adaptable and modular communication gateways specifically designed for electrical facilities and electricity distribution systems
- Takes almost no space on a DIN-rail
- From meter data concentration to protocol conversion – full range of protocols (DNP3.0, IEC 61850 (MMS & GOOSE), DLMS, Modbus, IEC 60870–5‑101/102/103/104 etc.) to communicate with all devices and control centers connected to your electrical network
- 1 Ethernet & 1 RS485/RS422 port and an optional RS232 port (copper or fiber) or 2G/3G/4G modem.
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 iGWlite can also process and transfer the data to one or multiple control centers and 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 supported by an iGWlite is open, simple and scalable, allowing 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 time, money and space on your DIN-Rail.

IEC 61850 MMS
The iGWlite can be used as a simple link between serially connected physical devices and logical IEC 61850 devices as it can be simply configured to map any signal from all sorts of data models onto IEC 61850 logical nodes, whilst also providing IEEE1588 / PTP time synchronization.
Thanks to its full iGrid protocol stack, the iGWlite can convert any standard or legacy protocol such as IEC 60870–5‑103, SPAbus, Modbus, DLMS to IEC61850, making it compatible with hundreds of vendors.
Standards and Compliance
The diverse backgrounds of our partners and clients from all over the world have helped us gather state-of-the-art know-how and firsthand experience in a great variety of energy applications. This joined knowledge is the foundation of our optimized iRTU/GW family, which has a proven track record of being particularly effective and resistant for a diverse range of applications and harsh environments belonging to the energy industry.
As a result, the iGWlite meets the requirements of extensive standards, such as IEC61850‑3, IEC60870‑2–1 & IEC60255-26.
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.
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.
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.
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 iGWlite 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.
