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

SIPLUS S7-300 CPU314C-2PN/DP WITH CONFORMAL COATING -25 … +70 DEGREES C BASED ON 6ES7314-6EH04-0AB0 . COMPACT CPU WITH 192 KBYTE WORKING MEMORY, 24 DI/16 DO, 4AI, 2AO, 1 PT100, 4 FAST COUNTERS (60 KHZ), 1. INTERFACE MPI/DP 12MBIT/S, 2. INTERFACE ETHERNET PROFINET, WITH 2 PORT SWITCH, INTEGRATED 24V DC POWER SUPPLY, FRONT CONNECTOR (2 X 40PIN) AND MICRO MEMORY CARD REQUIRED

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.
