1Overview of Safety Instrumented System SIS Module CP319F-2PN/DP

SIMATIC S7-300 CPU319F-3 PN/DP， Central processing unit, with 2.5MB memory, 1 MPI/DP 12MBit/s interface, 2 DP Master/Slave interfaces, 3 Ethernet PROFINET interfaces, requires a miniature memory card, order number: 6ES7318-3FL01-0AB0.

Safety Instrumented System SIS Module CP319F-2PN/DP,Fault safe CPUs have high processing performance, large capacity program memory, and program scale, which are used to establish fault safe automation systems and are suitable for factories with increased safety instrumented system (SIS) requirements.

Compliant with safety requirements of SIL 3 (IEC 61508) and PL e (ISO 13849.1), distributed fault safety I/O modules can be connected locally through an integrated PROFINET interface (PROFIsafe) and/or through an integrated PROFIBUS DP interface (PROFIsafe); The fault-tolerant ET 200M I/O module can also be centrally connected. For non safety applications, standard modules can be operated centrally or distributedly to achieve a distributed intelligent system (PROFINET) in component-based automation. The PROFINET agent can be implemented in synchronous mode on PROFIBUS, which is used for PROFIBUS DP intelligent devices in component-based automation (CBA). The operation of the CPU requires SIMATIC miniature storage cards.

Safety Instrumented System SIS Module CP319F-2PN/DP,The CPU 319F-3 PN/DP is the fastest S7-300 CPU with a large capacity program memory. It is particularly used in factories with extended automation tasks and strict safety requirements.

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

Distributed I/O devices with fail safe I/O modules can be connected through three built-in interfaces. The ET 200 M fault-tolerant I/O module can meet safety related applications.

Network automation solutions (or fail safe solutions) can be achieved through the built-in communication options of the CPU without the need for other components.

CPU 319F-3 PN/DP features:

Extremely high processing and communication performance

1.4 MB working memory;
By expanding the working memory to execute and run user programs, the space for user programs can be significantly increased. For security related programs, it is necessary to increase the memory space by more than 5 times. The micro memory card (up to 8 MB) used as program loading memory also allows for the saving of items (including symbols and annotations) in the CPU. Loading storage can also be used for data archiving and recipe management.

Flexible scalability;
Up to 32 modules, (4-row structure)

MPI/DP combination interface;
The first integrated MPI/DP interface can establish up to 32 connections with S7-300/400 or with programmers, PCs, and OPs simultaneously. In these connections, always reserve one connection for PG and one connection for OP respectively.
Using MPI, a simple network of 32 CPUs can be established through "global data communication". This interface can be reset from MPI interface to DP interface. The DP interface can be used as a DP master station or DP slave station for operation.
PROFIBUS DP interface:
Fully supports PROFIBUS DP V1 standard. This can enhance the diagnostic and parameterization functions of DP V1 standard slave stations.

DP interface;
The second integrated MPI/DP interface can establish up to 32 connections with S7-300/400 or with programmers, PCs, and OPs simultaneously. In these connections, always reserve one connection for PG and one connection for OP respectively.
The DP interface can also be used as a DP master or DP slave. On this interface, the PROFIBUS DP slave can operate in isochronous mode and fully supports the PROFIBUS DP V1 standard. This can enhance the diagnostic and parameterization functions of DP V1 standard slave stations.

Ethernet interface;
The third built-in interface of CPU 319F-3 PN/DP is a PROFINET interface based on Ethernet TCP/IP. It supports the following protocols:

S7 communication is used to exchange data between SIMATIC controllers

Programmer/OP communication for programming, debugging, and diagnostics through STEP 7

PG/OP communication is used to connect with HMI and SCADA

Open TCP/IP, UDP, and ISO on TCP (RFC1006) communication via PROFINET

SIMATIC NET OPC Server is used for communication with other controllers and CPU built-in I/O devices

Password protection;
By using a password, the user program can be protected from unauthorized access.

Diagnostic buffer;
The last 100 error and interrupt events are saved in the buffer for diagnostic purposes.

Maintained data backup;
When the power fails, the CPU will automatically save all data (up to 700KB), and these data will remain unchanged when the power is restored.

5Safety Instrumented System SIS Module CP319F-2PN/DPcommunication

Safety Instrumented System SIS Module CP319F-2PN/DP,Realize safety related communication and standard communication between the central controller and distributed stations through PROFIBUS DP and/or PROFINET. The specially developed PROFIsafe supports the transmission of user data with security features in standard data packets. No other hardware components are required, such as a special safety bus. The required software can be integrated into hardware components as an extension of the operating system, or loaded into the CPU as a software block.

VISafety Instrumented System SIS Module CP319F-2PN/DPMODE

Safety Instrumented System SIS Module CP319F-2PN/DPThe safety function is included in the F program of the CPU and the fault safety signal module. The signal module uses differential analysis methods and test signal injection techniques to monitor input and output signals. The CPU checks the correctness of the controller's operation through periodic self checks, command testing, and logic and time-based program execution checks. In addition, I/O can also be detected through "sign of life" requests. When the system diagnoses a fault, it will enter a safe state. The operation of CPU 319F-3 PN/DP does not require F run authorization.

7Safety Instrumented System SIS Module CP319F-2PN/DPprogramming

Safety Instrumented System SIS Module CP319F-2PN/DPThe programming method is the same as that of SIMATIC S7 system. Non secure user programs can be created using programming tools such as STEP 7.

Option package SIMATIC S7 Distributed Safety (Classic) and SIMATIC Safety Advanced V12 (TIA Portal V12)

The STEP 7 option package "SIMATIC S7 Distributed Safety" (Classic) or SIMATIC Safety Advanced V12 (TIA Portal V12) is used for programming safety program segments. The option package includes all the functions and blocks used to create the F program. F programs with security features are linked to special function blocks in F-FBD or F-LAD or using the F library. The use of F FBD or F LAD can simplify the configuration and programming of factories, as well as simplify acceptance testing due to a unified representation format that is independent of specific factories. Programmers can configure secure applications without the need for other tools.
