6ES7212-1AE40-0XB0 Siemens CPU 1212C Original Brand New

• Controller for intro to S7 with basic expansion options
• Expandable by:
  • 1 signal board (SB), battery board (BB) or communication board (CB)
  • 2 signal modules (SM)
  • Max. 3 communication modules (CM)

The compact Siemens 1212C has:

• 3 device versions with different power supply and control voltages.
• Integrated power supply either as wide-range AC or DC power supply (85 … 264 V AC or 24 V DC)
• Integrated 24 V encoder/load current supply:
  For direct connection of sensors and encoders. With 300 mA output current also for use as load power supply.
• 8 integrated digital inputs 24 V DC (current sinking/current sourcing (IEC type 1 current sinking)).
• 6 integrated digital outputs, either 24 V DC or relay.
• 2 integrated analog inputs 0 … 10 V.
• 2 pulse outputs (PTO) with a frequency of up to 100 kHz.
• Pulse-width modulated outputs (PWM) with a frequency of up to 100 kHz.
• Integrated Ethernet interface (TCP/IP native, ISO-on-TCP).
• 4 fast counters (3 with max. 100 kHz; 1 with max. 30 kHz), 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. RS 485 or RS 232.
• 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).
• PID controller with auto-tuning functionality.
• Integral real-time clock.
• Interrupt inputs:
  For extremely fast response to rising or falling edges of process signals.
• Removable terminals on all modules.
• Simulator (optional):
  For simulating the integrated inputs and for testing the user program.

• Comprehensive instruction set:
  A wide range of operations facilitate 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

The STEP 7 Basic programming package permits complete programming of all Siemens S71200 controllers and the associated I/O.
