Our substation automation software has been developed to control and monitor any substation (HV & MV). It supports all architectures based on Windows or Linux servers, as well as embedded controllers, acting as a substation gateway, bay controller, RTU or communication front-end for SCADA systems.
The data collection from meters, protection relays, and other IEDs can be managed using any protocol, inlcuding IEC 60870–5, IEC 61850 (MMS/GOOSE), DNP3, DLMS, Modbus or Procome. Further, the iGW-VM 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.
Amongst its state-of-the-art features, the iGW-VM is able to provide load shedding functionalities, high accuracy time stamping/processing (<1ms accuracy) as well as straightforward PLC programming/automation according to IEC 61131–3 via the free iConf tool.

iGW-VM as Substation Gateway
Example schema of iGW-VM operating as substation gateway with hot-standby redundancy
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.
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-VM features 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.
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.
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.
iConf – One Configuration Tool for Everything
iGrid products, including devices operating with iGW-VM can all be locally and remotely configured and maintained via USB or Ethernet, using iGrid’s free iConf tool or standard software tools such as telnet. Alternatively, configuration data can be up– or downloaded via USB flash drive, FTP manager or iConf.
We recommend using the iConf tool because it has been specifically developed for electrical applications, saving you lots of time and money throughout the control system set-up and maintenance tasks, whilst also minimizing your project risks.
