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.

DeviceNet Safety Scanner
|
The 1753-DNSI scanner provides DeviceNet network access for GuardPLC 1600 and GuardPLC 1800 controllers. The scanner supports both CIP Standard and CIP Safety DeviceNet communication to DeviceNet safety I/O as well as to standard PLCs, standard I/O, and HMIs. The scanner reads and writes data from DeviceNet nodes and exchanges this data and status information with the GuardPLC controller. Using its target mode, the scanner can look like I/O to standard PLCs or HMIs, allowing the GuardPLC controller to send status and diagnostic data to the standard control system. Use RSNetWorx Software for DeviceNet to configure the DeviceNet Safety Scanner. See RSNetWorx for DeviceNet Software software for more information.
Benefits
- Supports both CIP Standard and CIP Safety communication on DeviceNet networks.
- Data sharing between up to 63 devices, 32 of which can be DeviceNet Safety I/O modules.
- Peer-to-peer communication between GuardPLC controllers and DeviceNet Safety devices.
- Configuration and monitoring over the DeviceNet network.
- DeviceNet Safety protocol has a higher priority so data is not influenced by standard DeviceNet communications.
- Certified by TÜV for use in applications to SIL 3 according to IEC 61508 and PLe/Category 4, according to ISO 13849-1
- ODVA conformance-tested to DeviceNet and DeviceNet Safety Specifications

When GuardPLC 1600 or 1800 controllers need additional safety I/O points, you can control and monitor your safety devices with Guard I/O. When used with GuardPLC 1600 or 1800 controllers, Guard I/O communicates on DeviceNet using CIP Safety protocol. As a proven technology, Guard I/O detects failures at the I/O and field device level, while enhancing operator protection.
CompactBlock Guard I/O modules are available in IP20 (in-cabinet) form factor. ArmorBlock Guard I/O modules are IP67 (on-machine) form factor. POINT Guard I/O provides maximum I/O density in minimal panel space.
