Triangle MicroWorks provides communication protocol Software Libraries (ANSI-C or .NET Components), conformance testing/simulation software, protocol gateways, and OPC drivers for industry-standard communication protocols such as Modbus, DNP3, IEC 61850, IEC 60870-6 (TASE.2/ICCP) and IEC 60870-5. The company's ANSI standard "C" Source Code Libraries and .NET Protocol Components are used by equipment vendors to cost-effectively implement Modbus, DNP3, IEC 61850, IEC 60870-6 (TASE.2/ICCP) and IEC 60870-5 communication protocols directly in the target hardware. The Communication Protocol Test Harness & 61850 Test Suite are Windows applications that can easily be configured as typical client or server devices. Tcl/Tk scripts are available in the Communication Protocol Test Harness to perform DNP3 & Modbus Server conformance test procedures. The Windows PC-based protocol gateways are used by system integrators and utilities as data concentrators and to translate between communication protocols. A full 21-day evaluation version of the SCADA Data Gateway, Communication Protocol Test Harness, 61850 Test Suite, and .NET Protocol Components may be downloaded directly from Triangle MicroWorks' website at

Product Name Type Connectivity Product Description
Modbus Source Code LibrarySoftware - ProgrammingModbus, Modbus TCP/IPTriangle MicroWorks (TMW) Source Code Libraries for DNP3, Modbus, and IEC 60870-5 are used by equipment vendors to cost-effectively implement these industry standard communication protocols directly in the target hardware. TMW's experience in developing communication protocol Source Code Libraries can shorten the time required to support these protocols, while allowing your engineers to focus on the company proprietary aspects of the product. Purchase includes one year of Maintenance and Enhancement Plan (additional years may be purchased), which provide support via e-mail, telephone or fax. Support includes assistance integrating the Source Code Library into your product as well as assistance troubleshooting any communications problems that may occur in the field. TMW's Communication Protocol Software Libraries are delivered in ANSI Standard C Source Code. They are designed to be both processor and operating system independent. Easy-to-use function based API will allow you to implement multiple combinations of Source Code Libraries on a single device by using many common utility files and conserving code space.
SCADA Data GatewaySoftware - Device DriverModbus, Modbus TCP/IPThe SCADA Data Gateway is a Windows(tm) application used by System Integrators and Utilities as an OPC Client/Server, Data Concentrator, or Protocol Translator. It supports the DNP3, Modbus, & IEC 60870-5 protocols. Translation to other protocols such as SNMP is supported by combining the SDG with another OPC Client/Server.
Communication Protocol Test HarnessSoftware - Testing and SimulationModbus, Modbus TCP/IPThe Communication Protocol Test Harness is a Windows(tm) application that simulates Master or Outstation devices, monitors communications, or performs custom functional tests. A module to automatically perform the Modbus Conformance Test Procedures is included with the standard Modbus license. It can be configured through a GUI or Tcl/Tk scripts. A configurable database of simulation points allows emulation of standard off-the-shelf devices. Additional instrumentation such as voltage or current generators can be controlled to automatically establish a test condition and confirm the expected results through the communication protocol.
