SmartGuard 600 Controller

Product Design

Networking with SmartGuard 600 Controllers



The SmartGuard 600 controller can function simultaneously as a DeviceNet safety master, DeviceNet safety slave, and DeviceNet standard slave as well as an EtherNet/IP target (see network illustration).

• As a DeviceNet safety master (1), 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.
  
• As a DeviceNet safety slave (2), 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.
  
• As a DeviceNet standard slave (3), 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.
  
• As an EtherNet/IP standard target (4), the SmartGuard 600 controller communicates with an Ethernet/IP standard originator, such as a CompactLogix or MicroLogix controller or an HMI device.
  
• As a limited EtherNet/IP bridge device (5), the SmartGuard 600 controller lets programming tools bridge to DeviceNet to view and program the SmartGuard 600 controller and configure other DeviceNet devices.
  

Configuration and Programming

You can program and configure the SmartGuard 600 controller through its USB port, through a DeviceNet connection or through an Ethernet connection. The SmartGuard's USB port has limited pass-through capabilities, letting you configure other devices on DeviceNet networks. You can use any type of A-to-B connection USB cable that supports USB 1.x or 2.0. Alternatively, you can connect to the SmartGuard controller through its DeviceNet port via a PCD card or a PC connected to an EtherNet/IP-to-DeviceNet linking device or gateway. You can also connect the 1752-L24BBBE SmartGuard controller to a PC's Ethernet port using a Category 5 Ethernet cable.

Safety System Management

Multiple system management tools are built into the SmartGuard 600 controller and RSNetWorx for DeviceNet software.

• You can password-protect the entire SmartGuard 600 controller so you cannot download any changes without the password. You can also password-protect the program with a separate password, to help prevent unauthorized edits to the program.
  
• Each safety device contains a configuration signature that changes any time the DeviceNet configuration or SmartGuard program changes, even if it is changed back to its original state. The configuration signature can be read by external devices, such as standard PLCs, HMI, or asset management software, to determine whether the configuration or program has been changed.
  
• Lastly, you can use the Safety Device Verification Wizard in RSNetWorx for DeviceNet software to safety-lock the SmartGuard 600 controller. Safety-locking via the Safety Device Verification Wizard verifies that the offline and online configuration and program are identical and provides documentation that you can keep in your files to show that the controller has not been tampered with.
