As a high-end PLC, s7-1500 takes only 1 ns to execute a single bool. For this high-performance PLC, how many axes can it take? For different control methods, the number of shafts is different, which can be roughly divided into two types, fb284 and process object method. We will explain how many shafts can be […]

OPC communication between WinCC and Siemens S7-200 smart CPU
Today, I’d like to discuss WinCC and S7 – OPC communication of 200 smart CPU. There is no relation between S7 and WinCC – 200 smart CPU communication driver, so WinCC and S7 – The communication between 200 smart CPUs through Ethernet can only be realized through OPC. S7 – As the sever end of […]
Siemens 828d primary vertical compensation function debugging
At the end of 2019, a vertical compensation experience of large-scale double column vertical lathe: because the tool rest is in different positions of x-axis, the x-axis beam will have different sag. In order to ensure the accuracy, we hope to compensate it through z-axis. This function is 828d option function purchase authorization 6fc5800-0am55-0yb0 note: […]
WINCC interface animation
Once upon a time, it was the pursuit of the industrial controller and the capital to show off to the operators that the operation interface displayed the vivid animation state of each equipment, reflecting the operation state of the field equipment. At that time, our company was in the period of rapid development, many projects […]
Siemens S7-400 CPU backup battery alarm processing
After the system has been put into operation for a period of time, during the inspection, it is found that the batt1 or batt2 indicator light on the power module of 400 CPU is always yellow, the BAF indicator light is always red, and the extf indicator light of CPU is always on. Through searching […]
Causes of electrolytic capacitor damage of frequency converter and matters needing attention in replacement
In judging whether the filter electrolytic capacitor is damaged or not, it can be judged as damaged when the electrolytic capacitor appears the following forms: appearance explosion, aluminum shell bulge, plastic jacket cracking, electrolyte outflow, safety valve opening or being pressed out, cracking of the top part of the small capacitor, serious corrosion of the […]
Usage of UDT data type in Siemens PLC
Usage of UDT data type in Siemens PLC 1、 What is UDT UDT is a user-defined data type. Sometimes, for convenience, users create a UDT (just like creating a DB block) and write a good data structure. Then, when creating a DB block, you can insert the UDT (enter a name and type the name […]
S7 communication between Siemens S7-200 smart PLC and s7-1200
1、 Matters needing attention and preparation for S7 communication between Siemens S7-200 smart series PLC and s7-1200 1. The S7 communication between s7-200smartcpu and s7-1200 has not been officially tested by Siemens. This document is only used by customers for testing. Any danger caused by using this communication mode shall be borne by customers themselves! […]
What is OPC? Architecture of OPC
What is OPC? OPC stands for OLE (object linking and embedding) process control. OPC is the most popular data connection standard for communication between controllers, devices, applications and other server based systems without the need to enter custom drivers for data transmission. A factory automation system or process consists of different controllers and devices from […]
