Using Timers and Counters in PLCs

Using Timers and Counters in PLCs

The heartbeat function of any automated system exists in PLC timers and counters. Role of timers is to measure delayed events, while counters play a significant role in calculating the frequency that certain events occur. Programmable logic controllers (PLCs) use timers and counters as an inbuilt component to enable machines to carry out specified work … Read more

Function Block Diagram (FBD): Visual PLC Programming

Function Block Diagram (FBD): Visual PLC Programming

Function Block Diagram (FBD) establishes a programming approach for PLCs by using visual blocks as an alternative to conventional programming code. Blocks in Function Block Diagram correspond to various functions that function through visual connections between the block elements. Visual programming through FBD allows complex ideas to become easier to follow due to immediate overview … Read more

Debugging and Troubleshooting PLC Programs

Debugging and Troubleshooting PLC Programs

You could say that Troubleshooting PLC programs can feel like solving a puzzle. The entire system stops when the code contains a type of logic mistake or an incorrect value. To efficiently discover the actual cause everyone must know appropriate troubleshooting methods. A step-by-step method allows personnel to check I/O signals in combination with reviewing … Read more

What Is Structured Text in PLC Programming?

What Is Structured Text in PLC Programming?

The main programming language used for PLCs (Programmable Logic Controllers) operates as Structured Text. Structured Text in PLC programming serves as a different programming language from ladder logic since its code resembles standard computer programming syntax. Text commands allow you to handle complicated data processing and complex logic added by simplified syntax. Manufacturing facilities now … Read more
