Application field

Simple and automatic

SIMATIC S7-200Micro PLC for chemical tasks

The field of application of the SIMATIC S7-200 extends from the replacement of relays and contactors to more complex automation tasks in stand-alone, networked and distributed configurations. The S7-200 also increasingly provides access to areas where special electronics have previously been developed for economic reasons.

In addition to the comprehensive basic functions of five different CPUs, the modular system technology of the SIMATIC S7-200 also provides a series of scalable special expansion modules to meet the extremely high functional requirements of various needs.

Due to its various distinctive features, the S7-200 has been proven worldwide in applications covering various industries:

Small CPU for Simple Automation Tasks - If you want to change to an efficient solution to perform simple automation tasks very economically, this is the better small device. Can also be used in an extended temperature range.

CPU for More Complex Tasks 222 Scalable Small CPU - Capable compact package for more complex machine and small system solutions.

CPUs for Higher Communication and Computing Requirements - High-performance CPUs for complex tasks requiring speed and special communication capabilities.

The CPU for simple drive tasks - the CPU 224 version for easy implementation of simple drive tasks - has two interfaces, two analog inputs and one analog output, as well as two 100 kHz pulse outputs and two high-speed 200 kHz counters.

High-performance CPU for larger technical tasks - multifunctional high-performance CPU for complex automation tasks with expanded inputs and outputs and two RS485 interfaces.

Weighing module

  • HMI functions
  • STEP 7-Micro/WIN software with Micro/WIN add-on library
  • Compelling system engineering - currently characterized by precise dimensions and optimal solutions for the various requirements of complete automation tasks Main features
  • Highlight memory cards for data logging, recipe management, project savings with STEP 7-Micro/WIN, and file storage in various formats
  • PID auto-tuning function
  • 2 built-in serial ports for extended communication options, eg for use with devices from other manufacturers (CPU 224 XP, CPU 226)
  • CPU 224 XP with built-in analog input/output

Advanced technology down to the last detail ensures that our CPUs play an outstanding real-time response rate:

  • 4 or 6 independent hardware counters, 30 kHz each, 2 x 200 kHz with CPU 224 XP, eg for precise path monitoring via incremental encoders or high-speed recording of process events
  • 4 independent alarm inputs with input filter time of 0.2ms to program start - maximum process safety
  • Pulse capture function for applications with fast events greater than 0.2 ms
  • 2 pulse outputs, 20 kHz each, or 2 x 100 kHz for CPU 224 XP with pulse width modulation and pulseless setpoints - eg: for controlling stepper motors
  • 2 timed interrupts, starting at 1ms, adjustable in 1ms increments - for bumpless control of rapidly changing processes
  • Fast analog input - with 25 μs signal transitions, 12-bit resolution
  • Real Time Clock

Timed Interrupt

  • 1 to 255ms with 1 ms resolution
  • Example: After a quarter turn, the signal can be recorded and processed on the screw inserter at 3000 RPM. Very precise recording of eg tightening torques is possible to ensure optimal tightening of screws.


Fast Counter

  • Run independently of each other, other operations and program cycles
  • Interrupt triggers when a user-selectable calculated value is reached - 300 μs response time from detection of input signal to switching output
  • 4-edge evaluation when incremental position encoders are used for exact positioning
  • Modular scalability

Alarm Input

  • 4 independent inputs
  • For registering signals in quick succession
  • 200 μs–500 μs response time for signal detection / 300 μs for signal output
  • Response to positive and/or negative signal edges
  • Up to 16 interrupts in a queue, depending on priority
