Siemens CPU module distributor--Product Introduction

The use of Siemens frequency converters in the Chinese market has long been in the steel industry,

Siemens frequency converter (Figure 1)

Breaking the previous monopoly of Japanese brand frequency converters in the market, according to statistics from relevant market research institutions, Siemens' high and low voltage frequency converters have already taken the lead in the market. Siemens frequency converters have been used in the steel industry for a long time. However, at that time, motor speed regulation was still mainly based on DC speed regulation. The application of frequency converters is still an emerging market, but with the continuous development of electronic components and the continuous maturity of control theory, frequency conversion speed regulation has gradually replaced DC speed regulation and become the mainstream of drive products. Siemens frequency converters have achieved super scale development in this market due to their brand effect. Siemens' successful development in the frequency converter market can be said to be the combination of Siemens brand and technology. The early Siemens frequency converters we encountered in the market mainly included SIMOVERTA for current sources and SIMOVERTP for voltage sources. These frequency converters also entered the market mainly due to the introduction of equipment, and are still in small use. Later on, the main ones sold in large quantities in the market were MICROMASTER and MIDIMASTER, as well as Siemens frequency converters as a successful series of SIMOVERT.

real-time response

The real-time response technology ensures that our CPU performs outstandingly with real-time response rates up to the next level of detail

1. 4 or 6 hardware counters, each 30 kHz, 2 x 200 kHz with CPU 224 XP, for example, through incremental encoders or high-speed path monitoring of process events

2. 4 * * * alarm inputs, input filtering time 0.2 milliseconds to program start - greater process safety

3. Pulse function for application fast events with signals greater than 0.2 ms

4. 2 pulse outputs, each 20 kHz, or 2 x 100 kHz for CPU 224 XP with pulse width modulation and pulse free set point - for example: used to control stepper motors

5. 2 timed interrupts, starting at 1ms and adjusted in increments of 1ms, for disturbance free control of rapidly changing processes

6. Fast analog input - with 25 μ s signal conversion and 12 bit resolution

7. Real time clock

Timed interrupt

1. 1 to 255ms, with a resolution of 1ms

2. For example, after a quarter turn, signals can be recorded and processed on the screw insertion machine at a speed of 3000 RPM. It can achieve very good records, such as tightening torque, to ensure better tightening of screws.

Fast counter

1. Each other, other operations, and program cycles all run * * *

2. When the user selectable calculation value is reached, the interrupt triggers a response time of 300 μ s from detecting the input signal to switching the output

3. When incremental position encoder is used for precise 4-edge evaluation

4. Modular Scalability

alarm input

1. 4 * * * inputs

2. Used for rapid and continuous registration of signals

3. Response time of 200 μ s-500 μ s for signal detection/300 μ s for signal output

4. Response to positive and/or negative signal edges

5. 16 more interrupts in a queue, depending on priority order

Mechanical characteristics

1. Installed horizontally or vertically on DIN rails or directly installed in the control cabinet using integrated drilling holes (not horizontal)

2. Junction box, used for wiring all CPUs and related components

Overview

The SIMATIC S7-200 is designed as a unified modular system. It provides a modular system that can be expanded to meet your needs. The expansion module has I/O from 4/4 to 32/32, analog modules from 4/0, 8/0, 0/4 to 4/1, and performance modules for switching loads: 5A DC or 10A relay real-time response.
