Single Platform, Multiple Functions

The Congruence.IQ Substation Gateway from Congruitive enables utilities and large energy users to collect, monitor, display, analyze, and archive data in a modern substation. The C.IQ Substation Gateway performs both traditional and advanced substation and distribution automation functions, providing a cost-effective, robust substation management solution.


The C.IQ Substation Gateway performs traditional substation automation functions — data acquisition and concentration, protocol conversion, sequence of events recording (SOE), annunciation, and more — as well as advanced substation and distribution automation applications. It can replace multiple systems in a substation with a single, robust solution, resulting in significant cost savings and increased reliability. Configuration is simple and intuitive. A highly scalable platform, the C.IQ Substation Gateway is designed for substations today and tomorrow.

Rich User Experience

The C.IQ Substation Gateway is available with a full-graphic HMI, allowing simultaneous display of multiple windows to give a complete overview of substation operations. The software displays station single-line diagrams, trends, and tabular data, and includes a full-featured display editor that enables creation of custom views and symbols. The C.IQ Substation Gateway can be coupled with a substation historian, allowing users to replay historical data and single-step through events. 

Complete Data Solutions

The C.IQ Substation Gateway collects data from devices over multiple master communication channels, and concentrates it into one or more slave devices. The system has built-in protocol conversion, supporting industry-standards such as DNP3, Modbus and IEC-61850. Channels operate in parallel to provide high throughput; and, support for serial and TCP/IP channels is provided. The system can acquire and transmit time-tagged data and add time tags when needed. The C.IQ Substation Gateway serves data to external systems using multiple protocols.

Built-In Alarm System

An alarm processor provides time-sorted display of events with millisecond accuracy. Different displays can be used to segment alarms into meaningful collections, such as voltage, severity, and type. The system supports up to 256, fully-configurable priority levels, allowing critical alarms to be extracted easily. C.IQ Substation Gateway provides audible alarms, which can be acknowledged from the display or graphical user interface. An auto-inhibit feature prevents malfunctioning inputs from clogging the display.
