Immediate write operation of Siemens PLC

For the ImmediateWrite function, you must generate a symbolic program segment as shown in the example below. For time-limited applications, you can send the current state of a digital output to the output template faster than the normal situation of once per OB1 scan cycle. The ImmediateWrite function can write a di

Understanding the development of the chip industry from the trends of Siemens EDA

In 2011, Mentor rejected a nearly $1.9 billion takeover offer from activist investor Carl Icahn, and then in 2016, accepted Siemens' $4.5 billion offer. The acquisition was completed in 2017, and in 2021, Mentor was officially renamed Siemens EDA. As Daniel Nenni of SemiWiki put it in an article: "Mentor was at a di

Stepper drive + stepper motor + Siemens PLC control case

Stepper motors are often used for positioning control. The number of pulses output by the PLC can control the angle of rotation (relatively speaking, it can be the distance), and the frequency of the pulses controls the speed of the stepper motor. However, it is simple, economical, and easy to control when used in s

Siemens S7-1200PLC with parameter programming and without parameter programming

Regarding S7-1200PLC programming with parameters and programming without parameters, mainly FC and FB, this programming method can mainly realize repeated calls and transplantation between programs; because FC has no background data block, when using FC, it is either programming without formal parameters or programm
