System Overview
The GuardPLC system is a state-of-the-art safety system offering fast safety PLCs, optimum controller throughput, and a reliable safety network.
The GuardPLC system meets the worldwide standard for programmable controls, complying with many of the latest global safety standards and the worldwide standard for functional safety in programmable electronic systems. The GuardPLC system can be used without restriction in applications up to Safety Integrity Level 3 (SIL 3) according to IEC 61508 and Category 4, PLe according to ISO 13849-1:2006.
The GuardPLC system consists of four main components:
- Packaged or modular controller and associated integrated I/O
- Safety Communication via GuardPLC Ethernet networks
- Distributed I/O modules for GuardPLC Ethernet networks
- Programming and configuration software
Benefits
Benefits resulting from the use of safety PLCs and safety networks include:
- Greater integration and flexibility of machine controls.
- Capability for better and easier diagnostics when intelligence is provided to the standard control level
- Faster and easier maintenance
- Reduction in the cost of installation, commissioning, and reconfiguring
- Reduction in design and hardware costs, compared to using safety relays alone for logic
- Potential for throughput performance improvement in more complex systems
