SIPLUS S7-300 CPU 314C-2 PN/DP Siemens

Область применения



The CPU 314C-2 PN/DP is the compact CPU for plants with a distributed structure. With its extended main memory, this compact CPU is also suitable for medium-sized applications. Integrated digital and analog inputs/outputs permit direct connection to the process. The integrated PROFIBUS DP master/slave and PROFINET IO Controller/I-Device interfaces allow the connection of distributed I/O sections over PROFIBUS and PROFINET. This allows the CPU 314C-2 PN/DP to be used as a distributed unit for high-speed preprocessing, and as a higher-level controller with a lower-level fieldbus system on PROFIBUS and PROFINET.

Other possible uses result from the integrated technological functions:

  • Counting
  • Frequency measurement
  • Period measurement
  • Pulse width modulation
  • PID control
  • Controlled positioning

Дизайн



The CPU 314C-2 DP is equipped with the following:

  • Microprocessor;
    the processor achieves an execution time of approximately 60 ns per binary instruction and 0.59 µs per floating-point operation.
  • Extensive memory;
    192 KB high-speed RAM (equals approx. 64 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)
  • Multi-point interface (MPI);
    the integrated MPI can establish connections to the S7-300/400 (up to 12 simultaneously), or to PGs, PCs, OPs. Of these connections, one is always reserved for PGs and one for OPs. With the MPI, it is possible to set up a simple network of up to 16 CPUs by means of "global data communication".
  • PROFIBUS DP interface:
    The CPU 314C-2 PN/DP with PROFIBUS DP master/slave interface allows a distributed automation configuration offering high speed and ease of use. From the user perspective, the distributed I/O is treated as central I/O (same configuring, addressing and programming).
  • Ethernet interface;
    the second integral interface of the CPU 314C-2 PN/DP is a PROFINET interface with 2-port switch, based on Ethernet TCP/IP.
    It supports the following protocols:
    • S7 communication for data exchange between SIMATIC controllers;
    • PG/OP communication for programming, commissioning and diagnostics via STEP 7;
    • PG/OP communication for interfacing to HMI and SCADA;
    • Open TCP/IP, UDP and ISO-on-TCP (RFC1006) communication via PROFINET;
    • SIMATIC NET OPC-Server for communication with other controllers and I/O devices with integral CPU
  • Integrated inputs/outputs;
    24 digital inputs (all for alarm processing) and 16 digital outputs as well as 5 analog inputs and 2 analog outputs make the CPU 314C-2 DP a fully-fledged controller.

Функции


  • 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 these, the last 100 entries are retentive.
  • 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 designation and location designation.
  • Startup;
    definition of the startup characteristics of the CPU and the monitoring time
  • Synchronous cycle interrupts;
    setting of IO system number, process image partition number, and delay 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

  • System diagnostics;
    determining handling and scope of the diagnostic alarms

  • Protection level;
    specifying the access rights to program and data
  • Communication;
    reservation of connection resources
  • Web;
    settings for the Web server of the CPU
  • MPI/PROFIBUS DP interface;
    setting the interface type. Determining node addresses. Parameterizing the operating mode and configuring the transfer areas in the case of PROFIBUS DP. Parameterizing the time synchronization
  • PROFINET interface;
    setting the addresses. Parameterizing the PROFINET properties, the I-Device functionality, the type of synchronization on PROFINET, the time synchronization using NTP procedure, the media redundancy, and the KeepAlive function. Assigning parameters to Port 1 and Port 2.
  • Digital inputs/outputs;
    setting of addresses, input delay and process interrupt
  • Analog inputs/outputs;
    setting of addresses;
    in the case of inputs: Setting the temperature unit, the measurement type, the measuring range, and the interference frequency;
    in the case of outputs: Setting 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 function "positioning";
    setting of addresses, parameterizing of "positioning with digital outputs" and "positioning with analog outputs"
  • Integrated "Rules" function

Display and information functions

  • Status and error indications;
    LEDs indicate hardware, programming, time or I/O errors, for example, and operating statuses 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
  • Routing
  • Data record routing
  • PROFIBUS DP master/slave
  • Open communication over TCP/IP, ISO-on-TCP and UDP
  • PROFINET IO Controller
  • PROFINET I-Device
  • PROFINET CBA
  • Web server

Integrated functions

  • Counters;
    4 counters (up to 60 KHz) with direction-dependent comparators, and for direct connection of 24V incremental encoders
  • 4 channels for frequency measurement;
    frequency measurement (up to max. 60 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;
    the period duration of the counting signal can be measured up to a counting frequency of 1 kHz
  • Pulse width modulation;
    4 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.
  • Controlled positioning;
    an SFB integrated into the operating system enables an axis to be positioned via 2 digital outputs or one analog output.
  • Alarm inputs (all digital inputs);
    the alarm inputs enable the detection of process events as well as the rapid triggering of responses.
