Pilz has provided clear guidance on what constitutes a strong password. The PNOZ m C0 operating manual recommends:
The primary risk of leaving the default password active is unauthorised access to the safety logic. A PNOZmulti system controls emergency stops, light curtains, safety gates, and two-hand controls. If an operator or malicious actor can connect to the device using the default password, they could:
Leaving the default password as pnozmulti poses a significant security vulnerability to industrial control systems (ICS). Unauthorized modifications to safety controllers can result in bypassed safety functions, machinery damage, or catastrophic physical injury.
⚠️ As soon as you successfully log in with these default credentials, change the default password immediately [8†L17-L18]. Leaving the default credentials unchanged represents a significant security vulnerability.

Securing programmable safety controllers is a critical aspect of industrial automation. The Pilz PNOZmulti series is an industry standard for configurable safety systems, protecting both human operators and expensive machinery. Managing access permissions via passwords ensures that only authorized personnel can alter safety configurations.
Pilz engineers may require you to send the physical chip card or an encrypted file extract to extract diagnostic data or verify if recovery is possible under strict safety protocols.
: Typically reserved for specific blocks that might need adjustment during commissioning without changing the core safety logic. What to Do if You Forgot the Password
The solution is straightforward and explicitly stated in Pilz documentation: Change the default password during project finalisation . Best practices include:
When Pilz provides sample project files, they are protected by the simple passwords 1 , 2 , and 3 , corresponding to access levels 1, 2, and 3. It is essential to understand that these are only for demonstration projects and Save the project and perform a fresh download
Comprehensive Guide to the PNOZmulti Configurator Default Password and Security Best Practices
Losing a password is never convenient, and the situation becomes even more challenging in a safety-critical environment.
are often just the numbers corresponding to the access level: Common Industry Defaults : Some users have reported
You will typically encounter this password prompt during the following actions:
To help narrow down any issues you are currently facing, let me know: The PNOZ m C0 operating manual recommends: The
The PNOZmulti Configurator uses a three-tier security system to control access to safety programs: Level 1 (Full Access)
The PNOZmulti Configurator is a graphic tool for configuring and programming units from the Pilz PNOZmulti modular safety system. It allows engineers to create safety programs for configurable small controllers using an intuitive interface, serving as the central hub for developing the logic that protects machinery and personnel in industrial environments.
When you create or work on a project in the PNOZmulti Configurator, you can protect it using a three-level password system. This graduated approach allows for different levels of access, ensuring that users only have the permissions they actually need.
While new projects require you to set your own passwords, you may encounter these standard credentials in specific contexts: Sample Projects:
