Overview

Powerful controller for extremely fast signal processing

Expandable by:
- 1 signal board (SB), battery board (BB) or communication board (CB)
- 8 signal modules (SM)
- Max. 3 communication modules (CM)

 

Design

The compact CPU 1217C has:

- Integrated 24 V encoder/load current supply: 
  For direct connection of sensors and encoders. With a 400 mA output current, it can also be used as load power supply.

- 14 integrated digital inputs, of which:
  + 10 integrated digital 24 V DC inputs (current sinking/current sourcing (IEC type 1 current sinking)).
  + 4 integrated digital 1.5 V DC differential inputs.

- 10 integrated digital outputs, of which:
  + 6 integrated digital 24 V DC outputs.
  + 4 integrated digital 1.5 V DC differential outputs.

- 2 integrated analog inputs 0 ... 10 V.
- 2 integrated analog outputs 0 ... 20 mA.
- 4 pulse outputs (PTO) with a frequency of up to 1 MHz.
- Pulse-width modulated outputs (PWM) with a frequency of up to 100 kHz.
- 2 integrated Ethernet interfaces (TCP/IP native, ISO-on-TCP).
- 6 fast counters (max. 1 MHz), with parameterizable enable and reset inputs, can be used simultaneously as up and down counters with - 2 separate inputs or for connecting incremental encoders.
- Expansion by additional communication interfaces, e.g. RS485, RS232, PROFIBUS.
- Expansion by analog or digital signals directly on the CPU via signal board (with retention of CPU mounting dimensions).
- Expansion by a wide range of analog and digital input and output signals via signal modules.
- Optional memory expansion (SIMATIC Memory Card).
- Motion Control in accordance with PLCopen for simple movements.
- PID controller with auto-tuning functionality.
- Integral real-time clock.
- Password protection.
- Interrupt inputs: 
  For extremely fast response to rising or falling edges of process signals.
- Time interrupts.
- Interrupt inputs.
- Library functionality.
- Online/Offline diagnostics.
- Removable terminals on all modules.
- Simulator (optional): 
  For simulating the integrated inputs and for testing the user program.

 

Function

- Comprehensive instruction set: 
  A wide range of operations facilitates programming:
  + Basic operations such as binary logic operations, result allocation, save, count, create times, load, transfer, compare, shift, rotate, create complement, call subprogram (with local variables)
  + Integral communication commands (e.g. USS protocol, Modbus RTU, S7 communication "T-Send/T-Receive" or Freeport)
  + user-friendly functions such as pulse-width modulation, pulse sequence function, arithmetic functions, floating point arithmetic, PID closed-loop control, jump functions, loop functions and code conversions,
  + Mathematical functions, e.g. SIN, COS, TAN, LN, EXP


- Counting: 
  User-friendly counting functions in conjunction with the integrated counters and special commands for high-speed counters open up new application areas for the user.


- Interrupt processing: 
  + Edge-triggered interrupts (activated by rising or falling edges of process signals on interrupt inputs) support a rapid response to process events.
  + Time-triggered interrupts.
  + Counter interrupts can be triggered when a setpoint is reached or when the direction of counting changes.
  + Communication interrupts allow the rapid and easy exchange of information with peripheral devices such as printers or bar code readers.


- Password protection
- Test and diagnostics functions: 
  Easy-to-use functions support testing and diagnostics, e.g. online/offline diagnostics.
- "Forcing" of inputs and outputs during testing and diagnostics: 
  Inputs and outputs can be set independently of cycle and thus permanently, for example, to test the user program.
- Motion Control in accordance with PLCopen for simple movements.
- Library functionality
