How to implement integral programming for S7-1200/1500 in STEP7 (TIA Portal)?
Integral is a mathematical calculation of the area of a given function curve. But the actual curve often does not have a clear mathematical relationship, but an analog quantity that changes with time. Integral calculation is to add all the area of the trapezoid surrounded by two process values and time. The trapezoidal area is … Continue reading How to implement integral programming for S7-1200/1500 in STEP7 (TIA Portal)?
How to input, read and edit the date and time variables of the CPU module in STEP7 (TIA Portal)?
Use the "T_CONV" instruction in S7-300/400 to extract the date, week and time data from "DT". This instruction needs to be called three times. Fill in the "DT" type variables in the parameter "IN" and fill in the variables defined as "Date", "Int" and "TOD" in the parameter "OUT" respectively. Switch from "DT" to "Date"Switch … Continue reading How to input, read and edit the date and time variables of the CPU module in STEP7 (TIA Portal)?
6 suggestions for who are beginning to learn PLC programming
Programmable controller is an industrial control device integrating computer technology, communication technology and automatic control technology. For beginners, they have mastered the basic principles of PLC and are familiar with commonly used programming methods. They can use them freely in simple system programming, but they are often incapable of designing more complex control systems. If … Continue reading 6 suggestions for who are beginning to learn PLC programming
Why TIA Botu V14 information system (online help) sometimes displays garbled characters?

The same program has different responses in different PLCs
PLC programming is based on the hardware system. Different hardware systems have different processing behaviors. If the programming is not rigorous, it will cause deviations in the results. Therefore, programming must be standardized. The advantage of standardization is that these deviations can be avoided. At the same time, the standardization of programming is also standardized. … Continue reading The same program has different responses in different PLCs
PROFINET_IO Vs RT
Profinet can be understood as a relatively special highway (such as the highway I saw in Indonesia), which is divided into three lanes: passing lane, driving lane, motorcycle lane… Then we often see Profinet IRT, Profinet RT corresponds to passing lanes and driving lanes. In addition, the Profinet we are talking about also has a … Continue reading PROFINET_IO Vs RT
