Effective implementation of ISO 13849-1

The PSR-TRISAFE safety module and the SAFECONF software help you meet the requirements for configurable safety systems quickly and effectively.

Effective implementation of ISO 13849-1 with PSR-TRISAFE and SAFECONF:

  • Easy handling for effective fulfillment of Cat. 4, PL e and SIL 3
  • Flexible safety logic for efficient creation and adaptation of safety functions
  • Safe logic test through integrated test and simulation mode


Safety technology changing to functional safety

As a continuation of EN 954-1, the ISO 13849-1 not only describes the structure of the safety parts hardware of a control system, but also the design of the software.

This standard states the requirements for the complete lifecycle of safety functions and recommends methods for implementation with configurable safety modules.

Implement your safety functions according to the standard - with the help of Phoenix Contact.


Specification of safety functions


The specification of safety functions describes the behavior of the safety logic. It thus forms the basis of all other activities and must be created at the start of the project.

Describe all safety requirements to be met, such as

  • Safety functions
  • Performance level of the safety functions
  • Machine and system reactions to errors and
  • Functions of the operating modes
Safe monitoring of the emergency off function

Error-free configuration of the safety logic


Three steps to an easy device configuration - with the SAFECONF configuration software

Use of validated function blocks in the software helps the user to prevent errors during safety logic configuration.

Create your safety logic safely and comfortably with the SAFECONF configuration software. Here, the extensive library of TÜV-certified function blocks will help you.




Correct parameterization of the safety functions


The function blocks must be parameterized according to the safety requirements from the specification.

Simply select the settings and the parameters of the function blocks with a mouse click in SAFECONF. If necessary, a clearly arranged and comprehensible online help is available.

Plausibility check of safety functions


Automatic check of the safety function
Automatic check of the safety function
Verification procedure in which the safety-related parameters are checked for plausibility, e.g. input of invalid values or reaction to incorrect connections.

Get your safety logic checked. SAFECONF automatically checks whether all block connections are correct and all signal cables are available. The point of error is shown automatically.




Manipulation protection for parameters


The configured safety logic and the set parameters must be protected against unauthorized or unwanted modifications.

For this, use the safety mechanisms of SAFECONF. In addition to hardware and software password protection, PSR-TRISAFE also provides additional protection with the Confirm button.

Safe transmission of configuration

The effects of deviations or incomplete settings when transmitting the configuration to the hardware must be controlled reliably.

The integrated testing procedure guarantees correct data transmission and prevents incomplete settings. You can thus avoid incorrect data being transmitted to the safety module.




Safety logic validation


The specified behavior and the efficiency of the safety logic are tested using a test plan with error situations.

Create a test plan and conduct a function test of the safety logic. In the simulation mode of SAFECONF, you can simulate error situations and monitor the signal values in the online mode.

Documentation of safety measures

Documentation of safety measures
The documentation must contain all lifecycle and modification activities of the safety logic. Specifications about parameter records, project planner and project date are also necessary.

Create a comprehensive project report automatically with SAFECONF at the click of a button. The report contains all necessary project information as well as the logic plan, revision status, project modifications and test results.




Quick startup of safety applications


Test the correct functioning of the safety applications directly on site on the machine or in the system.

Use the Force function for selective setting of the PSR-TRISAFE outputs. The selective startup of machines or system parts helps to control the behavior of the downstream safety functions easily and clearly and thus to start them up faster.

Safe operation of your machine or system

Use the safe competitive advantages and design your safety concepts according to the new requirements for configurable safety systems.

For safe operation, PSR-TRISAFE and SAFECONF offer extensive diagnostics options such as alarm outputs, diagnostics LED as well as a simple connection to PROFIBUS networks. Secure maximum productivity for your production with reliability and availability.
