For medium-complexity machines, the Pilz PNOZmulti modular safety controller is far more cost-effective than using multiple safety relays or a traditional safety PLC. This is partly as a result of the reduced purchasing cost but also because the configuration can be so easily created or modified. Another advantage of the PNOZmulti is its built-in diagnostics.
Version 5 of the PNOZmulti firmware and Configurator offers extra functionality for creating safety circuits utilising safety mats, safety gates with interlocks, pushbuttons, limit switches, key switches, foot switches and light curtains with muting functions. Additional fault messages and remedies have also been added into the firmware to aid fault diagnosis and reduce downtime. Customers using versions 2, 3 or 4 of the PNOZmulti Configurator software with the version 5 firmware can download of the additional message sets free of charge so the diagnostic information can be interpreted.
Only one software licence is needed to configure any number of PNOZmulti safety controllers. By downloading the new message sets from the Pilz website, users will be able to connect a laptop PC to the PNOZmulti to interrogate error stacks and, with the new message sets installed on the PC with the version 2, 3 or 4 Configurator, they can interpret the diagnostic information. This will save time during both commissioning and troubleshooting.
The new message sets can be downloaded free of charge from the PNOZmulti Downloads page of the Pilz website. The two downloaded files simply need to be placed in the PNOZmulti Configurator folder to replace the old files.
