iGW – Master of Protocols & Data CollectionSubstation automation, data concentration, protocol conversion, generation control.. you name it! The iGW is smart and highly adaptable, solving all of your network challenges efficiently.
Our secure gateway has been designed for particularly strong protocol conversion, network redundancy and SCADA automation (incl. IEC 61850). It is thus the perfect choice to set up, automize or retrofit generation plants, substations and other control networks requiring data concentration or conversion between several protocols, as for instance Modbus to Ethernet or IEC 61850 to DNP3.
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 iGW can also process and transfer the data to one or multiple control centers or 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 based on iGWs is open, efficient and scalable, as it allows 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 lots of time and money.
- Secured, advanced and adaptable communication units suitable for all energy environments, from HV substations to power plants
- Internal switch with RSTP/ PRP/ HSR redundancy for more reliability
- 2 Ethernet ports, 4 serial ports, and optional, internal 4G, 3G and GPRS modems
- Collect information from up to 24 meters (up to 10,000 tags), process it with user-defined mathematical/logical operations and send the new data to control centers through any kind of communication network.
- 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
iGW as Substation Gateway and Bay Control Unit
Example schema of iGW applications with hot-standby redundancy
The iGW comes with 2 independent 10/100 BaseTX Ethernet ports (two different MAC addresses, RJ45 connector) and an internal Ethernet switch with (2) 10/100BaseTX, (2) fiber optic FX100 sensors with ST, SC o SFP connectors, and RSTP /PRP /HSR redundancy.
Additionally, the iGW carries 4 software configurable serial ports: 1 full RS-232/RS-485/RS-422 + 2 basic RS-232/RS-485/RS-422 and 1 RS-422/RS-485 port (EXP422) to connect iRTUe models. Optionally, one of the serial ports can be replaced with an internal 4G(LTE), 3G and GPRS modem.
In a hot-standby architecture, the active iGW continuously feeds the recorded data to the redundant standby iGW to ensure that the newly active iGW has all the historical information (no data loss) when the switchover occurs.
If the active RTU detects that any IED is not able to communicate, it tries to access the IED via the hot-standby RTU, which (in the case there was a connection problem) can pass the data to the active RTU, acting as a serial server.
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 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.
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.
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 iGW 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 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.

In this HV substation automation project the iGW-S3 (Ethernet switch model) enables the upgrade to IEC 61850, communicating with the Procome protection relays and mapping all their information (including signals, alarms, measures and commands) into IEC 61850 logical devices.
In this project the iGW was deployed by a major meter manufacturer in over 150 generation plans, concentrating 8 high-end meters through DLMS as well as mapping and sending the data to the control center via the IEC60870‑5–104 and Modbus RTU.
In this project the iGW converts from IEC 101 to IEC104 in order to comfortably expand the SCADA system of the metro lines, using high technology switches and SDH equipment via Ethernet. The iGW controls the low power substations (380 Voltage grid) by reading the data from a SIEMENS PLC via IEC 101, mapping it to IEC104, and sending it to the existing SCADA Control Center.
They are IEC 61850 (GOOSE) compliant and come in many configurations such as 48 DI, 16 relays, 16 AI, 24 DI + 8 relays, 24 DI + 8 AI or 8 relays + 8 AI.
iControl is a high-performance SCADA for the monitoring and control of data collected in electrical networks, such as substations, MV grids, power plants or railway systems. It is able to run either in client/server or standalone mode, handles most protocols and provides advanced functionalities such as hot-standby redundancy, automatic line coloring, events notification (via e‑mail and sms), SQL logging, or the automatic generation of reports.
