Recently, a friend of mine used Siemens’ safety PLC for the first time. Since most safety-related content in Siemens PLC is in English, there were many areas that were not very clear. He reached out to me for discussion and learning. Indeed, using the safety features of Siemens PLC requires some time for beginners.So today, … Read more
Previously, a colleague privately messaged me to create a tutorial on Siemens OPC UA. Recently, I have been quite busy and did not have time to set up the system for testing and verification. Today, I happen to have some free time, so I will create an article about Siemens OPC UA, covering both the … Read more
↑ Click on the above “ITOT Partner” Follow us Written in front of you As GMP regulatory standards continue to tighten, more and more pharmaceutical companies need to connect their production equipment to information management systems. However, most companies (foreign companies usually complete planning during equipment procurement or new plant construction stages) did not uniformly … Read more
Continuing from yesterday’s draft, batch reading data blocks from multiple Siemens PLCs (or the V area of S7-200 smart, unidirectionally sending to N clients)Yesterday’s Go project (or compiled exe) can directly read variables from S7-200 smart, obtaining runtime data even without the counterpart program (see GitHub: s7-200smart-v-binary-viewer)New project: S7-SSE-gateway, also open-sourced on GitHub, everyone is … Read more
Note that in the programming system of Siemens PLCs (especially TIA Portal), the more professional and accurate terms are Temporary Variables and Static Variables, which typically play the role of “intermediate variables.” The term “intermediate variable” is more of a functional description. Below, I will elaborate on its core concepts. — 1. Principle: The “Draft … Read more

Configuring I-Device in the same project I-Device refers to IO devices equipped with a CPU. All CPUs of the S7-1500 PLC and S7-1200 PLC can function as I-Devices and IO controllers. Below is an example demonstration of motor control using the I-Device functionality. The CPU1511-1 PN of the S7-1500 PLC communicates with the CPU1214C AC/DC/RLY … Read more
(In the debugging area of a food factory, Xiao A is holding a regular SD card, looking worriedly at the card slot of the S7-1200 PLC — he just tried to copy a program using a regular SD card, but not only did it fail, it also prompted “Storage card incompatible,” and the firmware update … Read more
Today, I would like to discuss a phenomenon related to the memory of Siemens PLCs. This concept is a fundamental knowledge point that is typically covered when learning about PLCs, often taught by instructors or institutions. However, many people may not pay much attention to it in actual projects.Phenomenon: Last year, during a renovation project … Read more
How can you quickly improve your PLC programming skills? With 15 years of experience in the automation industry, I have the authority to speak on this.Thinking back to when I first encountered automation PLCs in 2010, my mind was blank; I couldn’t understand the client’s requirements, and I felt anxious when seeing projects, leading to … Read more
