CPU 319-3 PN/DP Application

The CPU 319-3 PN/DP is the fastest S7-300 CPU with a large program memory. It is used in plants containing distributed automation structures in addition to centralized I/O. It is used, for example, as central controller in production lines or as machine controller with high processing speed demands.

Its quantity framework makes it optimally suitable for use of SIMATIC engineering tools, e.g.:

  • Programming with SCL
  • Sequence programming with S7-GRAPH

Furthermore, the CPU is an ideal platform for simple software-implemented technological tasks, e.g.:

  • Motion control with Easy Motion Control
  • Solving of closed-loop control tasks using STEP 7 blocks or standard/modular PID control runtime software

Enhanced process diagnostics can be achieved by using SIMATIC S7-PDIAG.

As a result of the CPU’s integral communications facilities, networked automation solutions are possible without additional components.

CPU 319-3 PN/DP Design

The CPU 319-3 PN/DP is equipped with the following:

  • Multi-processor system
  • High command processing and communications performance
  • 2 MB work memory (corresponds to approx. 680 K instructions);
    the extensive work memory for program components relevant to execution offers sufficient space for user programs. SIMATIC Micro Memory Cards (8 MB max.) as load memory for the program also allow the project to be stored in the CPU (complete with symbols and comments) and can be used for data archiving and recipe management.
  • Flexible expansion capability;
    max. 32 modules (4-tier configuration)
  • Combined MPI/DP interface;
    The first MPI/DP integrated interface can establish as many as 32 connections simultaneously to S7-300/400 or connections to PG, PC, OP. Of the connections, one is permanently reserved for programming devices and one for OPs.
    The MPI supports simple networking of up to 32 CPUs over “Global data communication”.
    This interface can be reconfigured from MPI interface to DP interface.
    PROFIBUS DP interface:
    The PROFIBUS DP V1 standard is fully supported. This increases the scope of DP V1 standard slaves in terms of diagnostics and parameterization capability.
  • DP interface;
    the second DP integrated interface can establish as many as 32 connections simultaneously to S7-300/400 or connections to PG, PC, OP. One of the connections is permanently reserved for PG and one for OP.
    The DP interface can be used as DP master or DP slave. PROFIBUS DP slaves can be operated in isochronous mode at this interface. The PROFIBUS DP V1 standard is fully supported. This increases the scope of DP V1 standard slaves in terms of diagnostics and parameterization capability.
  • Ethernet interface;
    The third integrated interface of the CPU 319-3 PN/DP is a PROFINET interface with 2-port switch based on Ethernet TCP/IP. It supports the following protocols:

    • S7 communication for data communication between SIMATIC controllers
    • PG/OP communication for programming, commissioning and diagnostics through STEP 7
    • PG/OP communication for interfacing to HMI and SCADA
    • Open TCP/IP, UDP and ISO-on-TCP (RFC1006) communication over PROFINET
    • SIMATIC NET OPC-Server for communication with other controllers and I/O devices with own CPU

CPU 319-3 PN/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 700 KB) in case of power failure so that the data are available again unchanged when the power returns.
