Modifying project properties or safety settings within the software environment. Understanding PNOZmulti User Level Management

The password allows changes to certain blocks, which may still be adapted during commissioning for example.

Understanding PNOZmulti Configurator Passwords When working with the Pilz PNOZmulti Configurator , managing passwords is a critical step for machine safety and configuration. Unlike many industrial devices that ship with a single factory-default login, the PNOZmulti system uses a multi-level password structure that is typically defined by the user during the initial project setup. Common Default Passwords

: Official sample projects from Pilz frequently use the following defaults: Level 1 : 1 Level 2 : 2 Level 3 : 3

This design is intentional. Allowing password bypass would defeat the purpose of implementing security in a safety system. Therefore, if you lose a project password and do not have a backup, the only option is to —which is precisely why passwords must be managed with care from the very beginning.

Which of the PNOZmulti Configurator software is installed?

However, confusion arises because the software allows users to password-protect individual project files ( .pnoz files) and hardware configurations (base units). In older versions of the software or on certain base units, a default setting might have been present, but modern best practices have moved away from this.

Full rights. Can modify safety logic, change hardware configurations, manage users, and transfer projects to the chip card.

Technical: treat the default as temporary, not permanent. Change it immediately during initial setup. If the device allows role-based accounts, create distinct credentials for configuration, maintenance, and monitoring. Use strong, unique passwords or passphrases, and where supported, enable multifactor controls or certificate-based authentication. Keep firmware and configurator software patched—manufacturers regularly release fixes that affect authentication flows and expose vulnerabilities.

If you forget the Level 1, Level 2, or Level 3 password for a , there is no master override or recovery mechanism. The password cannot be read from the project file, nor can Pilz Customer Support recover it on your behalf. The official Pilz FAQ for the Japanese market states:

If you are working with official Pilz sample projects, the default passwords are often set as: 1 Level 2: 2 Level 3: 3 How to Resolve Password Issues (Lost Password)

There’s also responsibility on the vendor’s side. Manufacturers should avoid shipping products with easily guessable or globally shared passwords. Better: unique per-device credentials, clear guidance on changing them, and secure recovery procedures that don’t trade security for convenience. When industry best practices shift, vendors need to lead, not lag.

Pilz implements a tiered user access management system within the PNOZmulti Configurator to ensure that only qualified personnel can alter safety logic. Access levels are generally divided into distinct categories to enforce the principle of least privilege. 1. Administrator Level
