    Chapter 2 Safety Functions Dual-channel Mode and Discrepancy Time To support dual-channel safety devices, the consistency between signals on two channels can be evaluated. Either equivalent or complementary can be selected. This function monitors the time during which there is a discrepancy between the two channels.

  • Page 25: Dual-Channels, Equivalent

    Chapter 2 Safety Functions Dual-channels, Equivalent In Equivalent mode, both inputs of a pair should be in the same (equivalent) state. When a transition occurs in one channel of the pair prior to the transition of the second channel of the pair, a discrepancy occurs. If the second channel transitions to the appropriate state prior to the discrepancy time elapsing, the inputs are considered equivalent.

  • Page 26: Dual-Channels, Complementary

    Chapter 2 Safety Functions Dual-channels, Complementary In Complementary mode, the inputs of a pair should be in the opposite (complementary) state. When a transition occurs in one channel of the pair prior to the transition of the second channel of the pair, a discrepancy occurs. If the second channel transitions to the appropriate state prior to the discrepancy time elapsing, the inputs are considered complementary.

    Chapter Considerations When Replacing POINT Guard I/O Modules What This Chapter Contains This chapter provides things to consider when replacing POINT Guard I/O modules when they are connected to GuardLogix or SmartGuard controllers. For more information, refer to the GuardLogix Controllers User Manual, publication 1756-UM020 and the SmartGuard 600 Controllers User Manual, publication 1752-UM001.
  • Page 112 Chapter 8 Considerations When Replacing POINT Guard I/O Modules The following, simplified example is of CompactBlock Guard I/O on a DeviceNet network. Your products may differ, but the function is the same. EXAMPLE The DeviceNet network supports 64 node numbers, so if you have 100 devices on multiple DeviceNet networks, there are at least 36 duplicate node numbers being used.

    Chapter 8 Considerations When Replacing POINT Guard I/O Modules Why You Need to Manually Set the SNN The examples above showed how the SNN is used to guarantee safety-connection integrity after the system is operational. But the SNN is also used to guarantee integrity on the initial download to the POINT Guard I/O module.

    Chapter 8 Considerations When Replacing POINT Guard I/O Modules GuardLogix Controllers versus SmartGuard Controllers There is one major difference in functionality between the GuardLogix and SmartGuard safety controllers that affects the replacement of safety I/O modules. GuardLogix controllers retain I/O module configuration on-board and are able to download the configuration to the replacement module.

  • Page 117 Chapter 8 Considerations When Replacing POINT Guard I/O Modules If the configuration downloaded to the module was not from the original DNT file, the configuration signature will not match the original. Even if you recreate the same parameters in a new DNT file, the time and date portions of the signature will be different so the connection to the SmartGuard controller is not made.
