Design

CPU 319F-3 PN/DP Design

The CPU 319F-3 PN/DP features:

High command processing and communication performance
2.5 MB main memory;
The extensive main memory for runtime-relevant program sections offers sufficient space for user programs. In the case of safety-related program sections, increased memory requirements (5 times larger) must be expected. 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 integrated MPI/DP interface can establish up to 32 connections simultaneously to the S7-300/400 or connections to PGs, PCs and OPs. One of the connections is permanently reserved for the PG and one for the OP.
With MPI, a simple network can be constructed with up to 32 CPUs using “global data communication”. This interface can be reconfigured from an MPI to a DP interface. The DP interface can be used as a DP master or as a DP slave.
PROFIBUS DP interface:
The PROFIBUS DP V1 standard is supported in full. This enhances the diagnostics and parameterization capability of DP V1 standard slaves.
DP interface;
the second integrated DP interface can establish up to 32 connections simultaneously to the S7-300/400 or connections to PGs, PCs and OPs. One of the connections is permanently reserved for the PG and one for the OP.
The DP interface can also be used as a DP master or as a DP slave. PROFIBUS DP slaves can be operated isochronously on this interface. The PROFIBUS DP V1 standard is supported in full. This enhances the diagnostics and parameterization capability of DP V1 standard slaves.
Ethernet interface;
the third integrated interface of the CPU 319F-3 PN/DP is a PROFINET interface based on Ethernet TCP/IP. It supports the following protocols:
- S7 communication for the exchange of data between SIMATIC controllers
- PG/OP communication for programming, start-up and diagnostics through STEP 7
- PG/OP communication for connection 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 an integrated CPU

Application

CPU 319F-3 PN/DP Application

The CPU 319F-3 PN/DP is the fastest S7-300 CPU with a large program memory. It is ideally suited to plants with extensive automation tasks and stringent safety requirements.

It can be used as a PROFINET IO controller and as a standard PROFIBUS DP master in the SIMATIC S7-300. The CPU 319F-3 PN/DP can also be used as distributed intelligence (DP slave).

Distributed I/O devices with fail-safe I/O modules can be connected over the three integrated interfaces. The fail-safe I/O modules of the ET200M can also be used centrally for safety-related applications.

The integrated communication options of the CPU support networked automation solutions (also fail-safe) without the need for additional components.

Function

CPU 319F-3 PN/DP Function

Password protection;
a password concept protects the user program from unauthorized access.
Diagnostics buffer;
the last 100 error and interrupt events are stored in a buffer for diagnostic purposes.
Maintenance-free data back-up;
all data (up to 700 KB) are automatically backed up by the CPU if the voltage is interrupted and are available unchanged after the voltage has been reconnected.

Parameterizable properties

The S7 configuration as well as the properties and response of the CPUs can be parameterized using STEP 7:

MPI multipoint interface;
determining station addresses
Start-up/cyclic response;
determining maximum cycle time and loading
Isochronous interrupts;
setting of DP master system, partial process image number and delay time
Clock bit memory;
setting of addresses
Retentivity;
setting of retentive areas
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 the type of synchronization in the AS or on the MPI
Protection level;
specifying the access rights to program and data
Operation;
selection of either test operation or process operation
Communication;
reserving the connection resources
PROFIBUS DP master/slave interfaces;
user-oriented address assignment for distributed I/O
PROFINET interface;
parameterization of time synchronization with NTP procedure
