GuardPLC 1800 Safety Controller

GuardPLC 1800 Controller



The GuardPLC 1800 controller takes all the features of the GuardPLC 1600 controller, then adds analog inputs and high-speed counters for specialized applications such as emergency shut down, flame control, and amusement park ride control.

Benefits

• 32 safety digital I/O points – designed specifically for interfacing with safety components such as e-stops and light curtains.
  
• 8 safety-rated analog inputs – for sensing temperature, pressure, etc.
  
• 2 safety-rated high-speed counters – for sensing speed, flow, and motion.
  
• Embedded 4-port Ethernet switch – eliminates the need for external networking hardware.
  
• Supports EtherNet/IP protocol for easy integration with standard PLCs and HMIs.
  
• Modbus RTU slave and PROFIBUS DP slave communication options – lets the controller connect to standard PLCs and HMI devices, and an RS-485 port is available for ASCII communication (read only).
  
• Expandability – Use GuardPLC Distributed I/O to expand your safety system.
  
• Removable terminal blocks – make swapping controllers an efficient task so operations can be up and running again quickly in the event of a failure.
  

Typical Applications

• Emergency shutdown
  
• Burner management systems
  
• Perimeter guarding for robot / weld cells
  
• Perimeter guarding for packaging machines
  

Product Design

The GuardPLC 1800 controller has the same features as the GuardPLC 1600 controller with additional I/O, including analog I/O and high-speed counters for specialty applications. Built-in I/O includes 24 digital inputs, 8 digital outputs, 8 analog inputs, plus 2 high-speed counters. With GuardPLC distributed I/O you can place additional safety I/O where your safety field devices are located, reducing wiring costs.

The GuardPLC 1800 offers a built-in four-port Ethernet switch and 100M GuardPLC Ethernet comes standard. For flexibility in connecting to HMI devices and standard PLCs, the controller includes EtherNet/IP, Modbus RTU Slave or PROFIBUS DP Slave, an RS-485 port for ASCII communications.

At 10 ms throughput, this controller is one of the fastest safety PLCs in the industry. Its exceptionally high mean time between failures helps increase the safety and reliability of your system. Removable terminal blocks make swapping controllers a quick task so operations can be up and running again quickly in the event of failure.

Communication

GuardPLC safety controllers communicate on a Safe Ethernet communications network called GuardPLC Ethernet. The network is certified by TÜV for use in safety applications up to SIL 3 and PLe/Category 4, and can be used for distributed safety I/O and peer-to-peer communications between GuardPLC controllers, as well as programming using RSLogix Guard PLUS! software. And because it’s Ethernet, you use standard category 5 cables, switches and routers.

Using GuardPLC distributed I/O, you can place your safety I/O where your safety field devices are located, reducing wiring costs. Peer-to-peer communications allow GuardPLC controllers running their own programs to interlock with each other for applications that need to link one manufacturing cell to others.

NetLinx Integration

The ever-increasing demand for both enhanced plant productivity and improved workplace safety has fueled a trend toward integrated safety control and standard control systems. Control system users now expect their safety systems to possess all of the efficiencies and conveniences of their standard controls. Today's modern manufacturing plants will not accept safety systems that compromise productivity. Both machine builders and end users expect that the cost of implementing and maintaining a safety system will continue to drop without reducing the level of protection to the user.

The first level of integrating your GuardPLC controller into your standard control system is at the information network level. The GuardPLC 1600 and 1800 controllers let you to accomplish this easily with embedded EtherNet/IP protocol. Able to run EtherNet/IP protocol at the same time as safety-rated GuardPLC Ethernet protocol, the GuardPLC controller uses EtherNet/IP protocol to communicate status about the safety control system to other standard devices such as PLCs (ControlLogix^®, FlexLogix™, CompactLogix™, SLC™ 500 or PLC-5^®), HMIs (PanelView™, PanelView Plus, VersaView^®) and others. The GuardPLC controller can even control standard I/O, like Flex I/O and POINT I/O, on an EtherNet/IP network. This capability lets you integrate your GuardPLC on the EtherNet/IP network already running in your plant.
