Triangle Research

Triangle Research International Inc (TRi Inc), incorporated in Delaware, USA in 2000 and Canada in 2004, has its headquarters in British Columbia.  TRi Inc is responsible for the direct sales, distribution and support of TRi Programmable Logic Controllers (PLCs) and Trilogi/iTrilogi programming software in all of North America. 

TRi Inc’s roots were found in Triangle Research International Pte Ltd (TRi), a company that started up in 1993 in Singapore, the gateway to manufacturing in Asia and the centre for regional manufacturing automation in the 80s and 90s. Staying true to its mission since its early days, TRi Inc had always been specialists in open-case, single-board programmable controllers that are reliable, advanced, easy to program and spec’d to the needs and competitive pricing requirements of the Automation OEMs world. Meeting the expectations of such a demanding market, it’s no wonder that TRi PLCs are just as popular with systems integrators in many industries as well as schools and training colleges throughout North America.

TRiLOGI is a Relay-Ladder Logic learning tool with a built-in real-time on-screen simulator. With TRiLOGI’s simulator, anyone could write ladder programs and immediately test them off a PC. Today, TRiLOGI is already a standard ladder-logic program learning tool used by many technical institutions in several countries including USA, Canada and SE Asia. In fact, we have received many valuable customer comments that programming with TRiLOGI dramatically reduces programming time required for a project compared to programming with other PLC’s programming tool.

Ethernet Enabled PLCs
In the world of "all-in-one" PLCs the inclusion of a standard Ethernet port is still few and far between. Triangle Research took the initiative and made it a standard feature across its product offering. Even the Nano-10 includes a standard Ethernet port enabled with ModBus TCP/IP.

Have you ever considered - What Are The Advantages of an Embedded Ethernet PLC? ESI provides you with some answers to this question.

Below is a comparison of PLCs with a similar I/O count. Based on the other products, we are using the FMD1616-10 as the yard stick by which we will measure other Ethernet enabled PLCs.
