The PNOZmulti series from Pilz is a cornerstone of modern industrial safety automation, enabling configurable, modular safety systems for machinery worldwide. Central to its operation is the PNOZmulti Configurator software, which allows engineers to design safety circuits using function blocks. While the software and hardware offer robust safety features, a recurring operational security concern is the handling of the default password used to protect project files and hardware against unauthorised modifications. This essay examines the nature of this default credential, the risks it introduces, and the critical need for its immediate change. Store the Level 3 design passwords in an
The password allows you to modify and save.
The first time you attempt to download a configuration to the PNOZmulti base unit (chip card or via USB/Ethernet), the software will prompt you to define a project password. This level cannot modify the safety program logic
Historically, many industrial software applications shipped with universal default credentials. However, because the PNOZmulti system is a safety-critical device governed by strict international standards (such as ISO 13849-1 and IEC 62061),
