What Triangle MicroWorks does

Triangle MicroWorks, Inc. is a privately held North Carolina-based software company that develops and licenses industry-standard communication protocol source code libraries and testing tools for the electric utility, OEM, and system integrator markets. Founded in 1994 and operating from Cary, North Carolina with 11–50 employees, the company has built a 20-plus-year track record in SCADA and substation automation, with its SCADA Data Gateway deployed in more than 70 countries. Its product portfolio is organized around three pillars: (1) ANSI C, C++, and .NET source code libraries for IEC 61850 (including GOOSE, Sampled Values, and Secure Routable GOOSE), DNP3 (with Secure Authentication SAv5), IEC 60870-5 series, IEC 60870-6 (TASE.2/ICCP), Modbus, and Synchrophasor; (2) testing and configuration tools such as 61850 Test Suite Pro, Communication Protocol Test Harness, Distributed Test Manager (DTM), SCL Navigator, Iron (TASE.2/ICCP), DNP3 Forge, Garibaldi, and Helinks; and (3) the SCADA Data Gateway, a UCA IOP-certified data concentrator and protocol translator supporting up to 200,000 server points across OPC UA/DA, IEC 61850, DNP3, IEC 60870-5/6, and Modbus.

The company monetizes primarily through one-time perpetual licenses for embedded source code libraries and testing tools, supplemented by recurring Maintenance and Enhancement Plans. Licensing is delivered via PC Seat, Network-Based, or Hardware-Based Dongle options, with free 10–21-day evaluation kits and a free RiseClipse OCL online SCL checker as top-of-funnel acquisition tools. Go-to-market is enterprise field sales augmented by inside sales, a customer web portal, and event-driven demand generation at DistribuTECH, PACWorld, CIGRE, IEEE PES T&D, and UCAIug events, plus an annual TMW User Group Meeting. The company is UCA IOP certified for both its SCADA Data Gateway and 61850 Test Suite Pro, and runs an active training ecosystem through its IEC 61850 Hands-On Training Series with digital certification via the Certifier platform.
