Two new tools released to help machine and equipment builders (OEMs), and manufacturers save time when designing machinery safety systems.

The Rockwell Automation Safety Automation Builder (SAB) configuration software and Safety Functions pre-engineered design documents help users navigate the safety-system design process and apply best practices.

The SAB tool is available as a free download from the Rockwell Automation website. It guides manufacturers through the safety-system design process by providing options for layout, safety performance level (PL) analysis based on ISO 13849-1 using IFA’s SISTEMA (Safety Integrity Software Tool for Evaluation of Machine Applications), and product selection using Allen-Bradley safety-automation products.

The SAB software automates the safety-selection process to help speed system design and minimize human error. With the SAB tool, users import an image of machinery and answer questions using a drop-down menu and help screens to identify and select the necessary safeguards. The software then compiles all product selections, generates a bill of materials, and compiles necessary data to populate SISTEMA. SISTEMA indicates the attained PL of the safety system using ISO 13849-1 through an automatic calculation. As part of the process, users also receive a SISTEMA project file.

A user can download the SAB software from the Rockwell Automation website, and it also requires users download and run SISTEMA.

To support the SAB tool, Rockwell Automation also released new Safety Functions, which are pre-engineered design documents containing detailed information for each safeguarding method, including specific functionality, PL and required input, logic and output components. These documents also include parts lists, electrical drawings, a SISTEMA project file, and verification and validation plans. After going through the SAB process, users can select the appropriate safety function needed for a particular machine and combine it with the bill of materials to design a complete safety system.
