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.
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.
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 2 Safety Functions Safety Input Fault Recovery If an error is detected, the safety input data remains in the off state. Follow this procedure to activate the safety input data again. 1. Remove the cause of the error. 2. Place the safety input (or safety inputs) into the safe state. 3.
Chapter 2 Safety Functions Safety Outputs Read this section for information about safety outputs. Safety Output with Test Pulse When the safety output is on, the safety output can be configured to pulse test the safety output channel. By using this function, short-circuits between output signal lines and the power supply (positive side) and short-circuits between output signal lines can be detected.
Chapter 2 Safety Functions Dual-channel Setting When the data of both channels is in the on state, and neither channel has a fault, the outputs are turned on. The status is normal. If a fault is detected on one channel, the safety output data and individual safety output status turn off for both channels.
Chapter 2 Safety Functions Muting Lamp Operation Beginning with firmware revision 1.2, we made changes to the operation of the (test outputs T1 and T3) muting status bits for the test outputs T1 and T3. Test outputs T1 and T3 are controlled by your PLC processor program to illuminate a muting lamp.

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.

Appendix Get I/O Diagnostic Status from Modules in Logix Systems Topic Page Introduction Message Instructions Introduction You can use message instructions in a Logix system to determine the cause of input point or output point faults. Message Instructions When the controller detects a fault on an input or output point, you can use a message instruction to explicitly retrieve the cause of the fault.
Appendix A Get I/O Diagnostic Status from Modules in Logix Systems This sample ladder logic is monitoring the status of output point 3. This ladder logic rung examines the Output Point Status and, when a fault is detected (0 = error), the message instruction is executed. Configure the Follow this procedure to edit the Message Configuration dialog box.
