The software uses three levels of access to manage security and prevent unauthorized changes: Level 1 (Full Access): Allows you to modify and save the safety project. Level 2 (Read-Only): Allows you to the logic and configuration but prevents any modifications. Level 3 (Limited Edits):
If you only need to view the configuration (e.g., for diagnostics) but not change it, some older base units allowed a read-only upload without a password. Modern firmware versions (firmware 1.0 and above on PNOZmulti 2) typically require the password for any upload.
Perform a factory reset on the base unit to restore all user data (including passwords) to the default values.
Safety programs are strictly protected to prevent unauthorized tampering. If the common defaults do not work, follow these steps to regain access: Sample projects PNOZmulti Configurator - Pilz US pnozmulti configurator default password
No password system is complete without physical security. Pilz is transparent about this limitation.
Beginning with , devices such as the PNOZ m B0 , PNOZ m B0.1 , PNOZ m B1 , and PNOZ m C0 include user management features that go beyond simple project protection. Every user who accesses the device or performs specific actions via the PNOZmulti Configurator must authenticate using their own credentials.
Give operator-level access (Level 2) for troubleshooting, and developer-level access (Level 1) only to authorized safety engineers. The software uses three levels of access to
The administrator account is the primary default account. Additional users can be created and configured in the PNOZmulti Configurator's user management system.
Allows users to view the program and project details but prevents any changes. Level 3 (Limited Modification):
Pilz PNOZmulti Configurator , there is no universal software-wide "default password" because passwords are set by the designer when a project is first created. However, if you are working with sample projects or common default setups, you can try the following: Common Default Passwords Sample Projects : The standard passwords for sample projects provided by Pilz Modern firmware versions (firmware 1
Pilz explicitly documents that the default password must be changed immediately after the first login. The official operating manual for the PNOZ m C0 base unit contains a highlighted security warning, referring to the default "pliz" password. A factory reset will return the device to this default state, so a password update must be part of any recommissioning process.
This is a significant point because it means the default password is not locked to the software alone but is instead tied to the physical device itself. The base unit stores the user database and enforces authentication before allowing configuration changes to be downloaded or applied.
