GuardPLC™ Safety Control Systems

GuardPLC offers superior speed in PLC throughput and network functionality, and meets worldwide PLC standards and global standards for functional safety in programmable electronic systems. Used in applications up to EN-954 Category 4 and IEC 61508 Safety Integrity Level 3 (SIL 3), they are ideal for sensing speed, direction, zero-speed, temperature, pressure, and flow applications. Features include embedded safety inputs, outputs, and multiple communication options, plus choose from several types of on-board and distributed I/O, high-speed counters, analog inputs and outputs, and dry contact safety relays.

Features:

• Easy Integration
  
  GuardPLC easily integrates into a standard control system. Communication options include GuardPLC Ethernet, EtherNet/IP, DeviceNet Safety, Modbus, Profibus, and ASCII.

• A Single Wire Solution
  
  GuardPLC offers a single wire Ethernet solution, running distributed safety I/O on GuardPLC Ethernet while communicating to standard PLCs and HMIs on EtherNet/IP. Both protocols run simultaneously on the same Ethernet cable. Additionally, GuardPLC can control standard I/O on EtherNet/IP, such as Flex I/O or POINT I/O, meaning increased flexibility to the system design.

• DeviceNet Safety
  
  Adding to network flexibility, the GuardPLC supports DeviceNet Safety via the DeviceNet Safety Scanner module. DeviceNet Safety allows a GuardPLC to control safety DIO on DeviceNet, communicate to PLCs and HMIs, plus control standard I/O devices on DeviceNet, such as stack lights, valves, push button stations, or POINT I/O.

• Certified Function Blocks
  
  Rockwell Automation offers Certified Function Blocks, application specific instructions that can be used in a GuardPLC controller's application program. Certified by TÜV, these function blocks make application development, debugging, and trouble-shooting quicker and easier. Instructions include E-Stop, light curtain, diverse input, two-hand run station, enable pendant, redundant output and pulse test output.
