Most PLCs in the industry are programmed by a highly specialized, well-established programming language called  " Ladder Logic ". Ladder Logic language has its strength in handling single bit digital I/O programming, but it is awkward to handle data processing where numerical data needs to be manipulated.

On the other hand, desktop computers are typically programmed by high-level languages such as BASIC , C, PASCAL, C++, Java etc. These powerful programming languages are designed for data processing, but they are not oriented towards flipping single bit digital I/Os.

By combining these two most important branches of programming languages into one single, seamless entity, we had invented the industry first " Ladder + BASIC " language that can easily handle sophisticated tasks with just a few lines of codes. We have also developed a family of M-series Super PLCs that are exclusively programmed in Ladder + BASIC language, using our highly acclaimed TRiLOGI PLC programming Editor, Compiler and Simulator software.  The following simple example illustrates how Ladder+BASIC language works in tandem:
