The World's Lowest Cost Ladder Logic PLCs
(with built-in RS485 Two-Wire Network Port)

"I think the E10-npn is a gem. I work in R&D and machine building for Die-Tech, Inc. ...  the E10 has proven to be a perfect fit for us.  The E10 made the electronics box smaller, cooler running, and more robust. And in the bargain, our manufacturing cost was cut by two-thirds. That's real value in a product.". -  Click here to read what other users say about our PLC products and services

I. Introduction     back to top

Finally, a Ladder-Logic based PLC so small and cost so little that it can effectively replace all those bulky relays, timers or counters found in your current control panels. Its 24V DC transistor outputs or 0 to 250V AC relay outputs eliminate the need for additional driver circuitry and its incredibly low price means you actually save money while getting a technically superior design for your next control panel project!

With their built-in RS485 interface, the new E10+ PLCs are ideal for distributed control where the I/Os are distributed to far away locations. The RS485 standard interface allows a twisted pair wire to connect PLCs at up to 1200 m (4000 ft) away!

Up to 255 E10+ PLCs may be connected to a master PLC such as the T100MD+ or to a host PC using the Auto485.  Each E10+ PLC can work standalone for fast local control and at the same time, their I/O status can  be remotely controlled and monitored by  the master PLC or by a PC.  Its simple ASCII based Host Link Commands are really  easy to use. You can see a Visual BASIC example here.

An E10+ PLC is programmable using an extremely user-friendly ladder logic editor-cum-simulator software -WinTRiLOGI Version 3.5 (Click here to download its Help document). This software now runs under Windows operating systems (95,98,ME, NT,2000,XP).  The same PC can be used to program either a single E10+ via RS232 interface, or up to 255 E10+ PLCs  via RS485 network.

WinTRiLOGI runs on any Windows PC. Featuring pull-down menus, pop-up windows and on-line context-sensitive help systems, TRiLOGI is the most user-friendly ladder logic editor available. Its built-in logic SIMULATOR allows you to perform complete off-line testing of your program on your PC screen without connecting to the target PLC. You can immediately verify our claim by downloading the evaluation copy of the TRiLOGI from our Internet Website: http://www.tri-plc.com/trilogi.htm   and finish writing the ladder program for your next project in no time!

(Notes: for existing E10npn or E10-Relay users: The new E10npn+ and E10Relay+ PLCs are backward compatible with the older generation E10 PLCs. This mean that you can continue to use the DOS TRiLOGI software that you have been using for many years to program the E10+ without switching to the Windows version. You will get the full 216 programming steps but your timers and counters are limited to 0-254. Only the WinTRiLOGI software supports 0-9999 range for E10+ timers and counters.)
