Siemens is from Germany. Founded in 1847, Siemens AG of Germany is a global leader in electrical and electronic engineering. Siemens has entered China since 1872, and for more than 140 years, it has persistently provided comprehensive support to China's development with innovative technologies, excellent solutions and products, and established its leading position in the Chinese market with outstanding quality and trustworthy reliability, leading technological achievements, and relentless pursuit of innovation.
Following the establishment of offices in London and St. Petersburg in 1850 and 1855 respectively, Siemens quickly set up offices in other parts of the world, such as Brussels (1871), Paris and The Hague (1879), Vienna and Warsaw (1879), Stockholm and Turin (1880), New York (1886), Tokyo (1887), Rio de Janeiro (1887), and Rio de Janeiro (1977). ), Rio de Janeiro (1888), Budapest (1890), Chicago (1892), and Johannesburg (1895).
Expanded information:
Siemens inverter is a well-known brand of inverter developed, produced and marketed by Siemens AG of Germany, which is mainly used to control and regulate the speed of three-phase AC asynchronous motors. And with its stable performance, rich combination of functions, high-performance vector control technology, low-speed high-torque output, good dynamic characteristics, super overload capacity, innovative BiCo (Internal Function Interconnection) function, and unparalleled flexibility, it occupies an important position in the inverter market.
Siemens is categorized by control scale:
Can be divided into large, medium and small machines.
Small machine: small machine control points are generally within 256 points, suitable for single machine control or small system control.
Siemens small machine has S7-200: processing speed of 0.8 ~ 1.2ms, memory 2k, 248 points of digital, analog 35 road.
Medium-sized machine: medium-sized machine control points are generally not greater than 2048 points, can be used for direct control of equipment, but also can be a number of the next level of programmable controllers to monitor, it is suitable for medium-sized or large control system control.
Siemens medium-sized machine S7-300: processing speed of 0.8 ~ 1.2ms, memory 2k, digital 1024 points, analog 128, network PROFIBU, industrial Ethernet, MPI.
Large-scale machine: large-scale machine control points are generally greater than 2048 points, not only to complete the more complex arithmetic operations but also to carry out complex matrix operations. It can be used not only for direct control of equipment, but also for monitoring and controlling multiple lower-level programmable controllers.
