Downloading of DOS Version of TRiLOGI:
Version 4.1 (Evaluation, 420K)
Installation will include both Version 3.3 for E10 and H-series and
Version 4.1 for T100MD+ and T100MX+ PLCs (Date stamp: Aug 15 1999)
Note: Although the new Windows version of TRiLOGI
has become the new favorite tool for PLC instructors, the original DOS version software
still has value for many people. Being a DOS based program means the software demands very
little computing power. In fact, the software runs lightning fast even on a 16MHz 80286
PC. Hence for institutes that do not have the latest, fastest Pentium machines, the DOS
version of TRiLOGI is still a great software for training students on PLC ladder logic
TRiLOGI software is the
industry's most user-friendly Ladder Logic Editor + Simulator Software. An
educational/evaluation version of this program is available for FREE downloading
here! This highly acclaimed PLC (programmable logic controller) software has been used by
many companies, colleges and technical institutes in many countries to train new users on
ladder logic programming, including Australia's RMIT, TAFE and USA's Old Dominion
University, Purdue University, Kent State University, etc. It is the only free ladder
logic software which allows real-time, off-line simulation of users' programs on the fly
on any IBM compatible PCs! This makes it a highly productive tool for new users or
students to learn ladder logic programming without having to fight for often limited
"PLC training stations". It is thus possible for the trainers to set more
challenging problems and test student-solutions easily with the help of the simulator.
"I use TriLOGI in the college classroom. I have each student download and install
TriLOGI on their home computer, and I then give them programming assignments to do at
home. They individually write, run and debug their PLC programs, and then email their
program files to me for testing and grading. Since TriLOGI will simulate PLC operation
off-line, each student is able to obtain hands-on programming and debugging experience
without having to wait for their turn on an expensive laboratory PLC. The students enjoy
using TriLOGI because they can see their programs run at home without loading them into an
actual PLC, it is easy to learn, and the cost for the off-line version is zero."
Prof John Hackworth, Old Dominion University
We welcome any technical institutes and colleges to use the TRiLOGI software to train
students on ladder logic programming at no charge at all! We would appreciate it if
you could email to us at: firstname.lastname@example.org
to inform us that you will be providing a link to our website at:
so that the students can download the TRiLOGI software from our web page to do their
homework! Suggestions and feedback on our products would be greatly appreciated.
Please tell your friends and colleagues about the program if you enjoy using it.
The software is actually an evaluation version of our TRiLOGI Ladder Logic Editor,
Simulator and Downloader software used for programming our entire range of Programmable
Controllers. The only difference being that the evaluation version does not support
communication with the actual PLC, which is NOT needed at all for simulation test of the
The evaluation version is almost identical to the fully functional version except with
some modifications being made to the communication modules. You can create and save ladder
logic program, simulate and test them thoroughly as though programming for a real-world
PLC application. The only restriction is that the created programs cannot be transferred
to the target PLCs using the evaluation version of TRiLOGI.
However, because users who are using the evaluation version of TRiLOGI
usually means that they have not yet purchased the PLC, communication with the target PLC
such as "Program Transfer", "On-Line Monitoring" etc cannot be
performed in any case. Hence in the evaluation copy of TRiLOGI these functions are not
truly implemented. Instead the user is presented with a mock-up display on screen to
demonstrate what will happen when the actual target PLC is connected and the relevant
command is executed. Despite the restrictions, the evaluation version of TRiLOGI is itself
a great learning and simulation tool for new or experienced Ladder-Logic programmers alike
who are able to quickly test out their ladder programs without connecting a single wire!
The evaluation version of TRiLOGI software is available here for free downloading. You
are reminded to read our copyright notice pertaining to the downloading of copyrighted
Please click at EITHER ONE of the following links:
1) Self-Extracting ZIP file (unzip in Windows 3.1 or Windows 95/98 only) - TLEVAL.EXE . Enter the drive or directory you wish to
install TRiLOGI evaluation program (default is "c:\tleval" ) and click
2) Compressed ZIP file (run in DOS) - The TRiLOGI (evaluation) software is compressed
into a ZIP file - TLEVAL.ZIP and you can download
this file into a temporary directory and unzip it using one of the popular unzip software.
Two files will be extracted:
At the DOS prompt, enter the command "INSTALL C:" to install the TRiLOGI
software to drive C: (or any other disk drive letter). A new directory: "TLEVAL"
will be created on the disk together with other sub-directories.
At the DOS prompt, type "TL" followed by the <Enter> key to start the
program. Three versions of the programs are provided:
- Version 3.3E - Exclusively for the E10 PLCs
- Version 3.3 - For all the H-series PLCs.
- Version 4.1 - For all the T100MX family of Super PLCs.
You will be prompted to select the PLC type from the menu. Alternatively, you may start
the relevant version of TRiLOGI program directly by running the following batch files:
- E10 (Version 3.3E) : TLE.BAT
- H-series PLC (Version 3.3): TLH.BAT
- T100MD / T100MX PLC (Version 4.1): TLM.BAT
Although it is only a DOS based program, TRiLOGI's extensive use of pull-down
menu, pop-up windows and on-line, context-sensitive help system make it the most
user-friendly relay-ladder program editor on the market today. We have made available the
TRiLOGI Programmer's Reference Part One and Two for downloading from this
Part One is the Ladder Logic portion of the TRiLOGI software which is applicable to all
our PLCs from E10 to T100MD1616+. Part Two is devoted to the TBASIC programming
language that is only applicable for the M-series PLCs run TRiLOGI Version 4.1. Both
