Writing and downloading our first program
Now comes the exciting part – writing our hello world program for the automation space. We are going to cover how to build a simple ladder logic program that will energize or de-energize a coil. This will help us establish a deeper understanding of how the Koyo Click software works. This is important as every PLC, SCADA, and Distributed Control System (DCS) follows the same set of guidelines and standards. Speaking of standards, one in particular that you should get familiar with is IEC 61131-3, as it helps define five core programming languages, as follows:
- Ladder diagram
- Functional block diagram
- Structured text
- Instruction list
- Sequential function chart
Similar to software programming languages where the core fundamentals are common across all languages, only the syntax changes for the most part and with these five languages, three are graphical-based and two are text-based. The CLICK programming software...
