پی ال سی زیمنس SIMATIC S7-200

Introduction Letter :

• powerful performance 
• optimum modularity and 
• open communications

• Small and compact – ideal for any applications where space is tight
• Basic and advanced functionality in all CPU models
• Large program and data memory
• Outstanding real-time response – being in total command of the entire process at any time means increased quality, efficiency and safety
• Easy-to-use STEP 7-Micro/WIN engineering software – ideal for both beginners and experts
• Integrated R-S 485-interface or use as system bus 
• Extremely fast and precise operational sequence and process control  
• Complete control of time-critical processes by time interrupts

• 5 distinct CPUs in the performance range with comprehensive basic functionalityand integrated Freeport communications interface
• A wide range of expansion modules for various functions:
  – Digital/analog expansions, scalable to specific requirements
  – PROFIBUS communication as a slave
  – AS-Interface communication as a master
  – Exact temperature measurement
  – Positioning
  – Remote diagnostics
  – Ethernet/Internet communications
  – SIWAREX MS weighing module
• HMI functions 
• STEP 7-Micro/WIN software with Micro/WIN add-on instruction library
• Compelling systems engineering – now featuring precise dimensioning andoptimum solutions for a wide range of different requirements for the completeautomation task

• Memory card for data logging, recipe management, saving of STEP 7-Micro/WIN project, and storageof documentation in various formats
• PID auto-tune function 
• 2 built-in serial ports for extended communication options, e.g. with other manufacturers’ devices(CPU 224 XP, CPU 226)
• CPU 224 XP with built-in analog inputs/output

• 4 or 6 independent hardware counters, each with 30 kHz, 2 x 200 kHz with a CPU 224 XP, e.g. for precise path monitoring with incremental encoders or for high-speed counting of process events
• 4 independent alarm inputs, input filter time 0.2 ms to program action – for maximum process safety
• Pulse-capturing function for signals > 0.2 ms for fast events from the application
• 2 pulse outputs, each 20 kHz, or 2 x 100 kHz with CPU 224 XP with pulse-width modulation and pulse no-pulse setpoint – e.g. for controlling stepper motors
• 2 timed interrupts starting at 1 ms and adjustable in increments of 1 ms – for bumpless control of rapidly changing processes
• Fast analog inputs – signal conversion with 25 μs, 12-bit resolution
• Real-time clock

• Between 1 and 255 ms, with a resolution of 1 ms
• For example: it is possible to record and process signals on screw insertion machine at 3000 RPM after just a quarter turn. This enables very precise recording, for instance, of tightening torques to ensure optimum fastening of the screw.

• Operating independently of each other, of other operations and of the program cycle
• Interrupt triggering when user selectable counted values are reached – reactiontime from the detection of an input signal to switching of an output is 300 μs
• 4-edge evaluation when incremental position encoders are used for exact positioning
• Modular expandability

• 4 independent inputs 
• For registering signals in rapid succession 
• Response time of 200 μs–500 μs for signal detection/300 μs for signal output 
• Response to positive-going and/or negative- going signal edge 
• Max. 16 interrupts in one queue depending on prioritization
