Most PLC programming consists of input contacts and output coils, which influence real-world outcomes through logical series/parallel combinations. —————————————————— Although each model of PLC seems to have its unique programming standards, there is indeed an international standard that most PLC manufacturers at least attempt to follow. This is the IEC 61131-3 standard, which will be … Read more
This thing can be quite confusing for beginners; just looking at that pile of PLC models can be overwhelming. I have been in this industry for nearly 20 years and have seen too many novices struggling with books only to arrive on-site completely lost. Let’s get to the point: when selecting a PLC, don’t just … Read more
Back in 2010, when I first took over a project to upgrade an automotive parts production line, the client insisted on obtaining real-time operational data from each piece of equipment. At that time, I was baffled: “Brother, your PLC only has 4K of memory, and it can’t even fit extra timers, yet you want real-time … Read more
Modbus Communication Programming Example (1) Recently, I have been writing about Modbus and fieldbus introductions separately, which are more conceptual and do not involve specific examples. Many readers may still find it insufficiently detailed. Since I am no longer engaged in specific programming debugging, providing direct examples is quite challenging. I referenced some materials from … Read more
Hello everyone, I am Da Yi! Today, we will discuss the similarities and differences between microcontroller programming environments and PLC programming software. From a practical perspective, microcontrollers are generally programmed using C language and require an Integrated Development Environment (IDE) such as Keil or IAR. In contrast, PLCs have dedicated programming software, with mainstream options … Read more
