S7-1200 PLC Communication The S7-1200 PLC is a compact controller launched by Siemens, supporting various communication protocols and interfaces, suitable for device interconnection in industrial automation scenarios. 1. Supported Communication Protocols and Interfaces 1. Integrated Interfaces PROFINET (default support) Supports real-time communication (RT) and isochronous mode (IRT), used to connect HMI, drives, remote I/O, and … Read more
The S7-1200 acts like an “intelligent security guard” in the factory, not only safeguarding its own “territory” but also maintaining close communication with the “command center” at headquarters.Edge computing transforms this compact PLC into a “field brain,” capable of processing data locally and responding quickly, while also uploading important information to the cloud for in-depth … Read more
The S7-1200 CPU provides up to 6 (1214C) high-speed counters, which count independently of the CPU’s scan cycle. The measurable single-phase pulse frequency is up to 100KHz, and for quadrature or A/B phase, it is up to 30KHz. In addition to counting, it can also be used for frequency measurement. The high-speed counter can be … Read more
An intelligent sensor network acts like the nervous system of a factory, while IO-Link technology serves as the “translator” of this system. Traditional sensors only communicate “on” and “off,” whereas intelligent sensors can provide detailed information—not just whether an object is present, but also how far away it is, how hot it is, and even … Read more

Invoking function blocks is akin to setting a one-button operation mode for various small appliances in a kitchen; just press a button, and it will automatically complete a series of actions. In the S7-1200, function blocks serve as “containers” for packaging reusable code, encapsulating commonly used control logic that can be called upon as needed, … Read more
Industrial automation equipment is usually not associated with “low power consumption”; however, in special scenarios such as remote monitoring stations and mobile devices, enabling the S7-1200 to enter “energy-saving mode” becomes necessary. This is akin to modifying a family sedan into an off-road vehicle, requiring a series of professional modifications, but it is absolutely feasible. … Read more
Hello everyone, I am an engineer with over ten years of experience in industrial automation, and I particularly enjoy tinkering with various DIY projects. Today, I would like to share an interesting project I recently completed – a smart home control system built with the Siemens S7-1200 PLC. I believe many friends want to make … Read more
Fault Diagnosis When the S7-1200 operates as a DP Master, the CPU does not stop and does not require downloading an organization block when a DP slave is lost. There are several methods for diagnosing faults in PROFIBUS DP: 1. Through the Indicator Lights on the Module The DIAG light on the front panel is … Read more
