Chapter 2 Understand the Operation of Safety Functions Topic Page Safety I/O Modules 25 Self-diagnostic Functions 26 Configuration Lock 26 I/O Status Data 26 Safety Inputs 26 Test Outputs Configured as Muting Outputs 34 Safety Outputs 36 Controlling Devices 38 Safety Precautions 38 Legislation and Standards 39 EC Directives 41 Read this chapter for information related to the safety functions of the modules.
Chapter 2 Understand the Operation of Safety Functions The module is designed for use in applications where the safety state is the off state. Self-diagnostic Functions Self-diagnostics are performed when the power is turned on and periodically during operation. If a fatal internal module error occurs, the red module status (MS) indicator is illuminated, and the safety outputs and input data and status to the network turn off.
Understand the Operation of Safety Functions Chapter 2 Using a Test Output with a Safety Input A test output can be used in combination with a safety input for short circuit detection. Configure the test output as a pulse test source and associate it to a specific safety input. The test output can also be configured for a power supply to source 24V DC for an external device, for example, a light curtain.
Chapter 2 Understand the Operation of Safety Functions When the external input contact is closed, a test pulse is output from the test output terminal to diagnose the field wiring and input circuitry. Using this function, short-circuits between input signal lines and the power supply (positive side), and short-circuits between input signal lines can be detected.
Understand the Operation of Safety Functions Chapter 2 Single Channel Mode If an error is detected, safety input data and safety input status turn off.
Chapter 2 Understand the Operation of Safety Functions Dual-channel Mode and Discrepancy Time To support redundant-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.
Understand the Operation of Safety Functions Chapter 2 equivalent dual pair, the data bits for both channels will always be sent to the controller as equivalent, both high or both low.
Chapter 2 Understand the Operation of Safety Functions complementary dual-channel pair, the data bits for both channels will always be sent to the controller in complementary, or opposite states.
Understand the Operation of Safety Functions Chapter 2 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. The safety input status turns on (fault cleared) after the input-error latch time has elapsed and the I/O indicator (red) turns off. The input data can now be controlled.
Chapter 2 Understand the Operation of Safety Functions Test Outputs Configured as Muting Outputs When test outputs are used as muting outputs, typically for a muting lamp, a circuit test is used to diagnose whether the circuit and lamp are operational. The muting circuit test is run every 3 seconds, regardless of whether the circuit is logic HI or LO. This could cause your muting output to flicker during normal operation when it is logic LO.
Understand the Operation of Safety Functions Chapter 2 In this code, the actual muting status bit is used in the first rung, and the DN bit of the timer is used in the muting status parameter of the instruction. The actual test output data bit is used in both the first and last rungs.
Chapter 2 Understand the Operation of 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 test pulsed, as shown in the figure and table. 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.
Understand the Operation of Safety Functions Chapter 2 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 Understand the Operation of Safety Functions Controlling Devices See this table for information about controlling devices. ATTENTION: Use appropriate devices as indicated in the Controlling Device Requirements table. Serious injury may occur due to loss of safety functions.
Understand the Operation of Safety Functions Legislation and Standards Chapter 2 Read this section to familiarize yourself with related legislation and standards information. Relevant international standards include the following: • IEC 61508 (SIL 1-3) • IEC 61131-2 • IEC 60204-1 • IEC 61000-6-2 • IEC 61000-6-4 • IEC 62061 The modules received the following certification from ODVA, when product is marked.
Chapter 2 Understand the Operation of Safety Functions North America In North America, the TUV-Rheinland type approval includes Guard I/O compliance to the relevant standards and related information including the following: • U.S. standards - ANSI RIA15.06, ANSI B11.19, NFPA 79 • The modules are UL-certified functionally safe and carry the NRGF label, when product is marked. • The modules received UL Listing to standards of U.S. and Canada when product is marked.
Understand the Operation of Safety Functions EC Directives Chapter 2 These products conform to the EMC Directive and Low-voltage Directive. For additional information, refer to the relevant installation instructions. EMC Directive Rockwell Automation devices that comply with EC directives also conform to the related EMC standards so that they can more easily be built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards.
Chapter 2 Understand the Operation of Safety Functions Examples to Reduce Noise These examples show how to reduce noise in 1791DS-IB12, 1791DS-IB8XOB8, and 1791DS-IB4XOW4 modules. EXAMPLE Reduce electrical noise from the communication cable by installing a ferrite core on the communication cable within 10 cm (3.93 in.) of the DeviceNet master unit.

Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software 7. Assign the output data. IMPORTANT 98 The test outputs that are configured as standard outputs on the module must not be used for safety purposes. Choose Description None Results in an input only connection to the module. Inputs and status are read, but no outputs are written. Safety Creates these safety tags and enables these outputs for use in the safety task. Test Creates these tags and enables the test outputs on the module.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 Choose Description Combined Creates these tags and enables all modules outputs, safety and test. Typically, you should choose Combined Status for the input status. This limits the packet size for normal communication. If you need detailed status when a fault occurs, that data is read explicitly via MSG instructions. Choose the appropriate input connection and add the output connection, if necessary.
Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software The Multicast connection type enables other safety controllers to read the safety input data by using this input connection. The Point to Point connection type does not enable this functionality. For other safety controllers to use this safety connection to read the input data, the connections must be identical. The RPI, connection name, and channel configuration must match so that this connection can be used by the other safety controller.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 Set the Communication Parameters Follow these steps to configure the communication parameters. 1. From the Add Safety Connection dialog box, click Advanced. The Advanced Safety Connection Properties dialog box appears.

Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software 2. In the Requested Packet Interval (RPI) box, enter the input connection RPI to support your application (from 6…500 ms). Selecting too small an RPI unnecessarily consumes network bandwidth; selecting too large an RPI increases safety reaction time. Selecting the appropriate RPI results in a system with optimized performance.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 Configuration Ownership—Reset Ownership The connection between the owner and the Guard I/O module is based on the following: • Guard I/O DeviceNet node address • Guard I/O safety network number • GuardLogix slot number • GuardLogix safety network number • Path from GuardLogix controller to Guard I/O module • Configuration signature If any of these change, the connection between the controller and the Guard I/O module is lost.
Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software The Reset Safety Device dialog box appears. Configuration Owner and Output Connection Owner(s) are checked by default. 2. To reset the device to an out-of-box condition, check Password and Safety Network Number. If you attempt to reset the device when a safety connection is active and the SmartGuard controller is in Run mode, you see this message. Put the SmartGuard controller into Idle mode and attempt to reset the 1791DS module again.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 Set the Safety Network Number (SNN) If you attempt to set the safety network number (SNN) when a safety connection is active and the SmartGuard controller is in Run mode, you see this message.

Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software The new SNN is sent to the 1791DS module. This dialog box appears informing you that the 1791DS configuration will be cleared when the SNN is changed. Next, this dialog box appears to allow you to confirm which module is about to have its SNN set. The network status indicator on the module that is about to have its SNN set is flashing red/green. 4. Click OK to confirm.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 Set Your Password You can set a password so that the configuration of the 1791DS module cannot be changed without first entering the password. Use of this password is not required to obtain SIL 3 integrity, because the configuration signature is part of the safety connection. If the configuration signature changes, the safety connection is lost. If you forget your password, you must contact Rockwell Automation to have it reset.
Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software I/O Data Tab You can put the 1791DS module in the scan list of a DeviceNet scanner, for example, a 1756-DNB bridge module. The 1791DS module will automatically appear in your list of available devices. Open the properties for the 1756-DNB module and click the Scanlist tab. The 1791DS module has preconfigured options for reading (and writing) standard data. To view them, open the properties of the 1791DS module and click the I/O Data tab.
Configure Modules in RSNetWorx for DeviceNet Software Chapter 6 These message types will appear differently, depending on the safety I/O module you select, but in general the: • bit-strobe and polled connections provide the I/O data values and channel status. • polled connection can write standard data to the I/O module. Only use this if the test outputs are configured as standard outputs, and those standard outputs can then be controlled from the scanner.
Chapter 6 Configure Modules in RSNetWorx for DeviceNet Software If you see the following message after attempting to download, the likely scenario is that the 1791DS module was previously owned by a different safety controller.
