Number Description
1 As a DeviceNet safety master, the SmartGuard 600 controller can control up to 32 Guard I/O modules.
These 1791DS and 1732DS modules are the same distributed safety I/O modules used with
GuardLogix® controllers.
2 As a DeviceNet safety slave, the SmartGuard 600 controller looks like distributed safety I/O to a safety
master. A GuardLogix or another SmartGuard safety master can read and write safety data to the
SmartGuard slave controller. This lets you perform distributed safety control through the interlocking
of multiple controllers via CIP Safety on DeviceNet networks.
3 As a DeviceNet standard slave, the SmartGuard 600 controller can look like a standard distributed I/O
module and respond to explicit messages so that standard DeviceNet masters like ControlLogix®, SLC™
500, or PLC-5® controllers or an HMI can read and write information to and from the SmartGuard 600
controller. This facilitates coordination with your standard PLC application, including displaying safety
system information on an HMI.
4 As an EtherNet/IP standard target, the SmartGuard 600 controller communicates with an Ethernet/IP
standard originator, such as a CompactLogix™ or MicroLogix™ controller or an HMI device. The
SmartGuard controller does not support CIP Safety on EtherNet/IP communication. As a result, the
SmartGuard controller cannot control 1791ES safety modules. All safety control must be done over the
DeviceNet network as shown in numbers 1 and 2 above.
5 As a limited EtherNet/IP bridge device, the SmartGuard 600 controller lets programming tools bridge
to DeviceNet to view and program the SmartGuard 600 controller and configure other DeviceNet
devices.
