Ladder Diagram programming for Pilz PAS4000

Pilz has incorporated Ladder Diagram programming into the PAS4000 software tool, making it easier to manage safety automation tasks.

Users can select three of the five programming languages from the International Standard IEC61131-3; Function block diagram, Instruction List and Ladder Diagram, providing a higher level of usability and flexibility.

All the programming languages can be combined with the PASmulti editor to simplify the design of complex programs - a feature that is claimed to be unique to the Pilz model.

The introduction of the Ladder Diagram programming follows from the release of EtherNet/IP connectivity in the previous release of PAS4000. The Pilz safety and standard control system can communicate with the common systems via ModbusTCP, Profibus-DP and EtherNet/IP natively, and utilise the additional gateway modules, CANopen and Ethercat.

Coupled with the PASmulti editor, the PAS4000 Ladder Diagram editor makes it easy to set up a safety PLC system. Versatile enough to be either used as a combined standard and safety PLC or as a standalone safety PLC, the tool has been implemented in solutions for mining, manufacturing, railway, bridge control, cable cars, oil platforms, hospitals, building fire protection and amusement rides.
