Design

The CPU 313C is equipped with the following:

  • Microprocessor;
    the processor achieves a processing time of 70 ns per binary instruction.
  • Extensive memory;
    128 KB high-speed work memory (equals approx. 42 K instructions) for program sections relevant to execution offer user programs sufficient memory space
    ; SIMATIC Micro Memory Cards (max. 8 MB) as load memory for the program also allow the project to be stored in the CPU (complete with symbols and comments).
  • Flexible expansion capability;
    max. 31 modules, (4-tier configuration)
  • MPI multi-point interface;
    the integrated MPI interface can establish as many as 8 connections simultaneously to S7-300/400 or to the PG, PC, OP. Among these connections, one is always reserved for programming devices and another for OPs. The MPI makes it possible to set up a simple network with a maximum of 16 CPUs via “global data communication”.
  • Integrated inputs/outputs;
    24 digital inputs (all can be used for alarm processing) and 16 digital outputs as well as 5 analog inputs and 2 analog outputs for current/voltage signals and an additional input for measuring temperature are available on the CPU 313C.

Function

  • Password protection;
    a password concept protects the user program from unauthorized access.
  • Block encryption;
    the functions (FCs) and function blocks (FBs) can be stored in the CPU in encrypted form by means of S7-Block Privacy to protect the know-how of the application.
  • Diagnostics buffer;
    the last 500 error and interrupt events are stored in a buffer for diagnostic purposes, of which 100 are stored retentively.
  • Maintenance-free data backup;
    the CPU automatically saves all data (up to 64 KB) in case of a power failure so that the data are available again unchanged when the power returns.

Parameterizable properties

The S7 configuration as well as the properties and response of the CPUs can be parameterized using STEP 7:

  • General;
    definition of the name, system ID and location ID
  • Startup;
    definition of the startup characteristics of the CPU and the monitoring time
  • Cycle/clock memory;
    specification of the maximum cycle time and load. Setting of the clock memory address.
  • Retentivity;
    definition of the number of retentive bit memories, counters, timers and data blocks
  • Time-of-day interrupts;
    setting of start date, start time and periodicity
  • Cyclic interrupts;
    setting of periodicity
  • System diagnostics;
    determining handling and scope of the diagnostic messages
  • Clock;
    setting the type of synchronization in the AS or on the MPI
  • Protection level;
    specifying the access rights to program and data
  • Communication;
    reservation of connection resources
  • MPI multi-point interface;
    determining station addresses
  • Digital inputs/outputs;
    setting of addresses, input delay and process interrupt
  • Analog inputs/outputs;
    setting of addresses, in the case of inputs: the temperature unit, the measurement type, the measuring range, and the interference frequency, in the case of outputs: the output type and output range
  • Integrated function “counting”;
    setting the addresses, parameter assignment of the modes “continuous counting”, “single counting”, “periodic counting”, “frequency measurement” and “pulse width modulation”
  • Integrated “Rules” function

Display and information functions

  • Status and error indications;
    LEDs indicate e.g. hardware, programming, time or I/O errors, as well as operating states such as RUN, STOP and start-up.
  • Test functions;
    the PG is used to indicate signal status during program execution, to modify process variables independently of the user program and to output the contents of stack memories.
  • Information functions;
    you can use the PG to obtain information about the storage capacity and operating mode of the CPU as well as the current loading of the main and load memories as well as current cycle times and diagnostic buffer contents in plain text.

Integrated communication functions

  • PG/OP communication
  • Global data communication
  • S7 basic communication
  • S7 communication (server only)

Integrated functions

  • Counters;
    3 counters (up to 30 kHz) with directionally-dependent comparators and to directly connect 24V incremental encoders
  • 3 channels for frequency measurement;
    frequency measurement (up to 30 kHz) enables, for example, measuring a shaft’s speed with speed range monitoring or throughput measuring (parts per measuring time) with range monitoring.
  • Period measurement;
    3 channels. The period duration of the counting signal can be measured up to a counting frequency of 1 kHz.
  • Pulse-width modulation;
    3 outputs to directly control valves, final control elements, switching devices, heating equipment, etc., switching frequency 2.5 kHz. The period length can be set and the pulse-pause ratio can be changed while running.
  • Alarm inputs (all digital inputs);
    the alarm inputs enable the detection of process events as well as the rapid triggering of responses.

The CPU 313C is the compact CPU for systems with demanding requirements regarding processing performance and speed of response. Integrated digital and analog inputs/outputs permit direct connection to the process.

Other possible uses result from the integrated technological functions:

  • Counting
  • Frequency measurement
  • Period measurement
  • Pulse-width modulation
  • PID control
