Application

The CPU 314 is the CPU for installations with high requirements in terms of processing power and reaction time. With its working memory this CPU is also suitable for medium-sized applications.

Design

The CPU 314 is equipped with the following:

  • Microprocessor;
    the processor achieves a processing time of approximately 60 ns per binary instruction and 0.59 µs per floating-point operation.
  • Extensive memory;
    128 KB high-speed RAM (corresponds to approx. 42 K instructions) for program sections 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. 32 modules, (4-tier installation)
  • MPI multi-point interface;
    the integrated MPI interface can establish as many as 12 connections simultaneously to S7-300/400 or to programming devices, PCs, OPs. Of 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”.

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, plant identifier and location ID. Parameter assignment of the multi-point interface MPI: Determining node 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
  • Clock interrupts;
    setting of start date, start time and periodicity
  • Watchdog interrupts;
    setting of periodicity
  • System diagnostics;
    determining handling and scope of the diagnostic alarms
  • Clock;
    setting of the synchronization method in the AS or on the MP
  • Protection level;
    specifying the access rights to program and data
  • Communication;
    reservation of connection resources

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)

System functions

The CPU provides many extensive system functions for diagnostics, parameterization, synchronization, alerting, time measurement, etc.
