The SIPLUS S7-300 CPU 314C-2 PN/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.

• 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.
