6 1) F-FB necessary in combination with S7 F Library V1.2+SPx 4 Safety-Relevant Software Components 4.1 SIMATIC Safety Matrix Option Package for S7 F/FH Systems The SIMATIC Safety Matrix Option Package is a toolkit that reduces configuration, testing, and maintenance time by merging the traditionally separate steps of creating a cause and effect matrix diagram, and configuring the safety system. Cause and effect matrix methodology is used for defining how and when actions are executed in a safety system. This methodology involves organizing process events into categories of causes and effects, and then linking these causes and effects. The links between the causes and effects are called intersections, which indicate what effects will result from an active cause. From this data, logic can be extracted to create a program for executing a system of responses to contain and prevent events before they cause damage to a process. The SIMATIC Safety Matrix Option Package requires S7 F Systems V5.2 or higher and S7 F- Library V1.2+SPx or S7 F Systems Lib V1.3 or higher. peter.weiss@tuev-sued.de Page 6 of 7

5 Non-Safety-Relevant Software Components Safety Matrix Engineering Tool Provides the complete suite of tools to create, configure, compile, and download matrices in the SIMATIC STEP 7 Engineering

7 5 Non-Safety-Relevant Software Components Safety Matrix Engineering Tool Provides the complete suite of tools to create, configure, compile, and download matrices in the SIMATIC STEP 7 Engineering Station (ES) environment. It additionally supports communication with a runtime Programmable Logic Controller (PLC) to allow testing of the matrix logic. Safety Matrix Viewer Supports matrices in the PCS 7 Operating Station (OS) of a PCS 7 WinCC environment. The Safety Matrix Viewer displays the runtime matrix logic in the PLC in a format consistent with that of the Safety Matrix Engineering Tool. Multiple levels of operator matrix functionality are protected by OS user rights. Safety Matrix Editor Provides the remote workstation the ability to create and review matrix logic without the need for SIMATIC STEP 7 or the PCS 7 environments. Matrices developed or modified on the Safety Matrix Editor can be conveniently ed, or otherwise shared with a Safety Matrix Engineering Tool user for incorporation into a SIMATIC project. Function Safety Matrix Engineering Tool Safety Matrix Viewer Safety Matrix Editor Version V5.2 and higher V6.0 and higher V5.2 and higher 6 Restrictions The Safety Matrix function blocks shall be automatically configured by the Safety Matrix Engineering Tool. The blocks are not intended to be placed individually on sheets by the user. Online forcing, parameter changes and maintenance overrides shall be applied as stated in the "Maintenance Override" guidelines and are the sole responsibility of the operator. This includes, that outputs shall not override ever. Munich, Jürgen Blum Technical Certifier peter.weiss@tuev-sued.de Page 7 of 7
