Pilz launches new safety calculator
Pilz Automation Technology is releasing a new version of its powerful PAScal software package for performing calculations when designing safety-related control systems for machinery in accordance with EN ISO 13849-1 or EN IEC 62061.
PAScal makes it much easier to ensure compliance with the standards' requirements, and it helps to save both time and costs. The new version, 1.2.0, includes a calculation graph as per EN ISO 13849-1, and benefits from a number of functionality and usability modifications enhancements. In addition, PAScal 1.2.0 runs on PCs with Microsoft Windows Vista.
As with the previous version, PAScal 1.2.0 features an intuitive graphical interface that enables users to visualise the safety system architecture. New to this version is the ability to open multiple projects, which is a major advantage when working on complex machinery or new projects that are similar to previous ones. Usability is further improved by means of context-sensitive help, and users now have greater control over their preferences.
PAScal enables a control system's safety functions to be broken down into sub-systems (such as sensors, inputs, outputs, actuators and logic), then the software calculates the overall probability of a dangerous failure per hour, and verifies the data with the prescribed performance level (EN ISO 13849-1) or safety integrity level (EN IEC 62061). The software can take into account possible alternative architectures and variations in the way components are connected together and parameterised. A useful improvement in version 1.2.0 relates to the way safety fieldbus connections can be configured.
When designing to EN ISO 13849-1, the calculator evaluates common-cause failures (CCF) and diagnostic coverage (DC) by considering factors such as shorts between contacts or synchronicity monitoring on multi-channel sensors.
