Safety I/O Devices

When you add a safety I/O device to the system, define a configuration for the device:
  • Node address for
    DeviceNet®
     networks.
    NOTE: A
    Compact GuardLogix®
     5380 controller can access devices on a
    DeviceNet®
     network only via a linking devices, for example, the 1788-EN2DN linking device. The controller can communicate with devices on the
    DeviceNet®
     network. However, typically
    Compact GuardLogix®
     5380 controllers use
    EtherNet/IP™
     networks to communicate with safety devices.
  • IP address for
    EtherNet/IP™
     networks.
  • Safety network number (SNN). To set the SNN, see Change a Safety I/O Device SNN.
  • Configuration signature. For information on when the configuration signature is set automatically and when you must set it, see Safety I/O Device Signature.
  • Reaction time limit. For information on setting the reaction time limit, see the GuardLogix 5580 and Compact GuardLogix 5380 Safety Reference Manual, publication 1756-RM012. Safety input, output, and test parameters complete the device configuration.
IMPORTANT:
You cannot add safety I/O devices while online with the controller.
