Design

The CPU 313C-2 DP 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 components relevant to execution offers sufficient space for user programs;
    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 programming device, 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”.
  • PROFIBUS DP interface:
    The CPU 313C-2 DP with PROFIBUS DP master/slave interface allows a distributed automation configuration offering high speed and ease of use. From the user’s point of view, the distributed I/O is treated as central I/O (same configuring, addressing and programming).
  • Integrated inputs/outputs;
    16 digital inputs (all for alarm processing) and 16 digital outputs are available on the CPU 313C-2 DP.

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
  • MPI multi-point interface;
    determining station addresses
  • 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
  • PROFIBUS DP master/slave interface;
    user-oriented address allocation for distributed I/O. Parameterizing the operating mode and configuring the transfer areas in the case of PROFIBUS DP. Parameterizing the time synchronization
  • Digital inputs/outputs;
    setting of addresses, input delay and process interrupt
  • 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 states 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)
  • Routing
  • Data record routing

Integrated functions

  • Counters;
    3 counters (up to 30 kHz) with directionally-dependent comparators and to directly connect 24 V incremental encoders
  • 3 channels for frequency measurement;
    frequency measurement (up to max. 30 kHz) enables, for example, speed measurement of a shaft 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 for direct control of valves, final controlling 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-2 DP is the compact CPU for systems with a distributed structure. Integrated digital inputs/outputs support direct interfacing with the process; the PROFIBUS DP master/slave interface supports connection to distributed I/O parts. The CPU 313C-2 DP can therefore be used both as a distributed unit for fast preprocessing and as a higher-level controller with a lower-level fieldbus system.

Other possible uses result from the integrated technological functions:

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