Preface This manual explains how to install and set up the 1715 Redundant I/O System. This redundant, modular system is designed to work in conjunction with a ControlLogix Enhanced Redundancy System. This system provides fault tolerant I/O and redundancy for use in critical process applications.
Preface Studio 5000 Environment The Studio 5000 Engineering and Design Environment combines engineering and design elements into a common environment. The first element in the Studio 5000 environment is the Logix Designer application. The Logix Designer application is the rebranding of RSLogix 5000 software and continues to be the product to program Logix5000™ controllers for discrete, process, batch, motion, safety, and drive-based solutions.
Chapter 1 Redundancy System Overview The 1715 Redundant I/O System lets a ControlLogix controller communicate to a remote, redundant I/O chassis by using EtherNet/IP. The 1715 Redundant I/ O system provides fault tolerance and redundancy for critical processes by using a redundant adapter pair and multiple I/O modules that have diagnostics and are easily replaceable. The modular architecture lets a system be built and adapted to suit the specific needs of an installation.
Chapter 1 Redundancy System Overview 1715 I/O Modules Both digital and analog I/O modules are available for use in this system, depending on your needs. I/O modules can be used singly or in pairs, providing configuration in either Simplex or Duplex modes. These are the 1715 modules that can be used in this system. Table 2 - Modules Available for the 1715 Redundant I/O System Cat. No.
Redundancy System Overview Chapter 1 Base Unit Structure The adapter base unit is always the leftmost base unit in the connection chain. The total length of the base unit connection chain, including all expansion cables cannot exceed 10 m (32.81 ft). A adapter module always occupies slot 0 or 1. An adapter base unit can support up to 8 I/O base units (up to 24 I/O modules). 1715-AENTR Adapter Modules The leftmost adapter module position, or slot, is 0. The rightmost adapter module slot is 1.
Chapter 1 Redundancy System Overview Module Positioning in the 1715 Redundant I/O System There are 26 total slot positions in the system numbered from 0…25. The first two positions always contain the redundant adapter module pair, in slots 0 and 1. The remaining positions begin numbering at slot 2 and contain the I/O modules, ending at slot position number 25. Any combination of simplex or duplex I/O module pairs can be used in the I/O base units. See Table 3 for a sample of what a system could look like.

Chapter 1 Redundancy System Overview Layout the Hardware This section discusses how to layout the system’s hardware by topology. System Context The redundant I/O subsystem must be connected to one ControlLogix redundancy system, or any Logix system that supports I/O via the EtherNet/IP network. All connections are established via the Ethernet network by using the topologies supported by the 1756-EN2T or 1756-EN2TR module, that is, DLR (Ring) or Star.

Redundancy System Overview Switchover Considerations Chapter 1 Each 1715 Redundant I/O System uses a single IP address as the primary IP address for all communication on the EtherNet/IP network. The redundant adapter module pair consists of two active modules, a primary adapter module and its partner, a secondary module. For the purpose of this document, the primary module is referred to as module ‘A’ and the secondary module is referred to as module ‘B’.
Chapter 1 Redundancy System Overview Obtaining a New IP Address The primary module’s IP address is stored in the adapter base unit through interaction with the TCP/IP object. If a stored primary IP address is available, the adapter uses that address. If a stored primary IP address is not available, then the adapter uses BOOTP/DHCP to obtain an IP address. The adapter transmits DHCP requests, but is able to process a BOOTP/DHCP response from either a DHCP or BOOTP server.
Redundancy System Overview Chapter 1 Ethernet Topology The 1715 Redundant I/O System supports DLR (Ring) and Star Topologies. For a DLR (Ring) Topology, the adapter modules’ Ethernet ports are configured with the outward-facing ports (Port 1 of Module A and Port 2 of Module B) operating as a 2-port switch. Port 2 of Module A and Port 1 of Module B are chained together.
Chapter 1 Redundancy System Overview For a STAR Topology, the adapter modules’ Ethernet ports are configured with the leftmost ports (Port 1 of Module A and Port 1of Module B) operating as a 2-port switch. The rightmost ports on each adapter are left unused.
Redundancy System Overview System Performance Chapter 1 This section discusses connections and RPI settings for the 1715 Redundant I/O System. Connections The adapter module has one required connection and does not support a rack connection. Each I/O module has one required connection (simplex or duplex). For example, the system in Figure 11 has five I/O modules. Four are duplex and one is simplex. They are all configured for data connection.
Chapter 1 Redundancy System Overview RPI The RPI you set specifies the maximum amount of time between data updates. The 1715 modules support an RPI range of 60…750 ms. Cat. No. Minimum RPI Maximum RPI Default RPI 1715-AENTR 60 ms 750 ms 180 ms 1715-IB16D 60 ms 1715-OB8DE 60 ms 1715-IF16 120 ms 1715-OF8I 120 ms Connection and Data Format The adapter and I/O modules each support a single data connection for input/ output data.

Chapter 3 Digital I/O Operation Each digital I/O module is an isolated module that plugs into a single position of the I/O base unit and a termination assembly that is mounted to the base unit. Digital I/O modules can be configured in RSLogix programming software as simplex or duplex and then by selecting one of the two available termination assemblies and the required number of modules.
Digital I/O Operation Chapter 3 1715-OB8DE Digital Output Module The digital output module interface consists of a combination of digital output modules and digital output termination assemblies. Each module provides 8 isolated output channels and plugs into a single position of the I/O base unit and a corresponding termination assembly. Digital outputs can be configured as simplex or duplex. The 1715-OB8DE digital output module has a flexible, fail-safe design, with eight field output channels.
Chapter 3 Digital I/O Operation Common Features The table lists several features available on 1715 digital I/O modules. Determining Input Module Compatibility Feature Description Removal and Insertion Under Power (RIUP) You can remove and insert modules while power is applied.
Digital I/O Operation Determining Output Module Compatibility Chapter 3 1715 digital output modules can be used to drive a variety of output devices. Typical output devices compatible with the 1715 digital outputs include the following: • Motor starters • Solenoids • Indicators When designing a system, do the following: • Make sure that the outputs can supply the necessary surge and continuous current for proper operation. • Make sure that the surge and continuous current are not exceeded.
Chapter 3 Digital I/O Operation Module Fault Reporting 1715 digital I/O modules provide hardware and software indication when a module fault has occurred. Each module’s status indicator, as well as the Logix Designer application, graphically displays this fault and includes a fault message describing the nature of the fault. This feature lets you to determine how your module has been affected and what action must be taken to resume normal operation.
Digital I/O Operation Chapter 3 • In your application, a controller already owns a module, has downloaded configuration to the module and is currently exchanging data over the connection between the devices. In this case, you can inhibit the module and the owner-controller behaves as if the connection to the module does not exist. IMPORTANT Whenever you inhibit an output module, it enters the Program mode and all outputs change to the state configured for the Program mode.
Chapter 3 Digital I/O Operation The table describes the two ways a module sends data to the owner-controller. Topic Description Requested packet interval A user-defined rate at which the module updates the information sent to its owner-controller. This is also known as Cyclic Data Transfer. Change of state Configurable feature that, when enabled, instructs the module to update its owner-controller with new data whenever a specified input point transitions from On to Off and Off to On.
Digital I/O Operation Chapter 3 1. Choose from the options in the Connection tab. Parameter Description Requested Packet Interval (RPI) Enter an RPI value or use the default. Inhibit Module Check the box to prevent communication between the owner-controller and the module. This option lets the module be maintained without faults being reported to the controller.

1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 For energize-to-action, dual power supplies are required for both the system and field supplies. The system provides the power supply monitoring, but this needs to be connected in the application. Requirements for Using 1715 I/O Modules You must follow these requirements when using 1715 I/O modules in a SIL 2 application.
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications IMPORTANT Requirements for ControlLogix-based SIL 2 Applications SIL 1 applications must use the wiring and measures defined for SIL 2 applications. Energize-to-action requires line monitoring for any SIL application. Add-On Instructions The Add-On Instructions provide a mechanism to verify the validity of data transferred between the ControlLogix controller and the 1715 adapter.
1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 Reaction to Faults The 1715-AENTR adapter reports faults via status indicators that turn red when a fault is detected in the adapter. Fault indications are also sent to the user application.
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications Safety Accuracy The I/O input modules determine the channel state and the line fault state by comparing the reported input values with user-programmed threshold values. For each channel of a module, two independent measurements are made. The discrepancy between these measurements is monitored to determine if it is within the safety accuracy limit.
1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 Reaction to Faults If an output module faults, the following status information is reported: • Module presence • Module health and status • Channel health and status • Field faults • An echo of the front panel indicators for each module If any of the following internal conditions exist, the output module fails safe: • Internal software error is detected • Over-temperature condition is detected • Power supply rails are out of tolerance The di
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications Analog Output Modules The analog output module can be used in applications where the output current is in the range 4…20 mA during normal operation including trip/action value and where 0 mA is the fail safe value. In these applications, one 1715-OF8I output module is sufficient for SIL 2 requirements, two modules provide a 1oo2 level.
1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 Shutdown Mode When the module is in the Shutdown mode, the Ready and Run indicators turn red. The default state is OFF (de-energized).
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications Enable SIL 2 Operation Follow these steps to enable a module for SIL 2 operation. 1. On the Module Definition dialog box, from the Series pull-down menu, choose Series A. 2. From the Revision pull-down menu, choose 2.001 or later. 3. From the Connection pull-down menu, choose Data. 4.
1715 Redundant I/O System in SIL 2 Safety Applications IMPORTANT Chapter 6 When online, the Reset button on the SIL 2 Safety tab appears solid when only the output data on any 1715 output module needs to be reset. See pages 218 and 244. The Reset button resets only output data for output modules, that is, the 1715-OF8I and 1715-OB8DE module outputs. To reset inputs for all 1715 modules, you must use the Reset Input parameter within the Add-On Instructions. See Performing a SIL 2 Reset on page 243.
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications • Each time a valid packet is received from the controller, the output module resets the CRTL. If the CRTL ever times out, the output module assumes the fail-safe state. IMPORTANT The default fail-safe state for all 1715 modules is de-energized. • It is recommended that the CRTL remain at the default of four times the RPI so that one invalid packet does not put the system into the safe state.
1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 Set Safe State Values for Inputs You must define the safe state values for inputs if the SIL 2 data verification checks have determined that the connection is not valid and the Connection Reaction Time Limit (CRTL) has expired. The default safe state value for digital inputs is OFF; for analog input modules, the safe state value is 0. Follow these steps to change the default values. 1. Click the Input States When CRTL Expires tab. 2.
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications Check SIL 2 Reset Status If one of more errors have persisted longer than the Connection Reaction Time Limit (CRTL), the connection uses safe state values and requires a reset to recover. When online, the SIL 2 reset status is displayed on the SIL 2 Safety tab for output modules. Click Reset to reset the connection and enable the output modules to control their outputs based on logic.
1715 Redundant I/O System in SIL 2 Safety Applications Chapter 6 IMPORTANT The Reset Counters button on the diagnostics tab resets only the counters shown in the 1715 I/O module profiles. It does not reset the counters displayed within the ControlLogix Add-On Instructions. This diagnostic information is populated by values retrieved from 1715 output modules. Equivalent input module diagnostic data is made available by the Add-On Instructions.

1715 Redundant I/O System in SIL 2 Safety Applications IMPORTANT Chapter 6 You must dedicate a specific task for safety-related functions and set that task to the highest priority (1). SIL 2 safety logic and logic intended for use in nonSIL 2 functions must be separate. The task period and task watchdog are configured in the Task Properties dialog box.
Chapter 6 1715 Redundant I/O System in SIL 2 Safety Applications This handles all fault scenarios: • If a controller fault, such as a watchdog fault occurs, the controller goes to program mode, which causes the 1715 I/O to go to the Program Mode states. • If there is a system fault that causes a communications loss to the I/O modules, then the 1715 I/O will go to the Fault Mode states.

Using SIL 2 Add-On Instructions with 1715 Redundant I/O Modules Performing a SIL 2 Reset Chapter 7 SIL 2 communication between a Logix controller and 1715 modules is achieved by the sender of the data encoding additional check data into the produced tag and the receiver of that tag by using that extra data (and time) to determine the data received is valid. Data can travel in either direction, that is, CLX -> 1715 and 1715 -> CLX. Each time the data passes the checks, it is deemed valid.
Chapter 7 Using SIL 2 Add-On Instructions with 1715 Redundant I/O Modules TIP A SIL 2 reset of output modules can be performed only by clicking Reset on the SIL 2 Safety tab of the Module Properties dialog box, or a LO to HI transition of the reset tag in the 1715 SIL 2 Add-On Instructions. When using input tags, that is, data from a 1715 input module to a ControlLogix controller, the 1715 module that produces the input tag generates additional check data as part of the tag.

Appendix B Electronic Keying Introduction The electronic keying feature automatically compares the expected module, as shown in the I/O Configuration tree, to the physical module before I/O communication begins. You can use electronic keying to help prevent communication to a module that does not match the type and revision expected. For each module in the I/O Configuration tree, the user-selected keying option determines if, and how, an electronic keying check is performed.
Appendix B Electronic Keying IMPORTANT Changing electronic keying selections online can cause the I/O communication connection to the module to be disrupted and can result in a loss of data. Exact Match Exact Match keying requires all keying attributes, that is, Vendor, Product Type, Product Code (catalog number), Major Revision, and Minor Revision, of the physical module and the module created in the software to match precisely to establish communication.
Electronic Keying IMPORTANT Appendix B Changing electronic keying selections online can cause the I/O Communication connection to the module to be disrupted and can result in a loss of data. Compatible Keying Compatible Keying indicates that the module determines whether to accept or reject communication. Different module families, communication adapters, and module types implement the compatibility check differently based on the family capabilities and on prior knowledge of compatible products.
Appendix B Electronic Keying EXAMPLE In the following scenario, Compatible Keying prevents I/O communication: • The module configuration is for a 1756-IB16D module with module revision 3.3. The physical module is a 1756-IB16D module with module revision 3.2. In this case, communication is prevented because the minor revision of the module is lower than expected and is not compatible with 3.3. Module Configuration Vendor = Allen-Bradley Product Type = Digital Input Module Cat. No.
Electronic Keying IMPORTANT Appendix B Changing electronic keying selections online can cause the I/O communication connection to the module to be disrupted and can result in a loss of data. Disabled Keying Disabled Keying indicates the keying attributes are not considered when attempting to communicate with a module. Other attributes, such as data size and format, are considered and must be acceptable before I/O communication is established.
Appendix B Electronic Keying EXAMPLE In the following scenario, Disable Keying allows I/O communication: • The module configuration is for a 1756-IA16 digital input module. The physical module is a 1756-IB16 digital input module. In this case, communication is allowed because the two digital modules share common data formats. Module Configuration Vendor = Allen-Bradley Product Type = Digital Input Module Cat. No.
Appendix C 1715-IB16D Digital Input Module Diagnostics Threshold Values for Digital Inputs This section describes how to calculate and set threshold values for digital inputs. The module determines the channel state and the line fault status by comparing the channel input voltage with defined threshold values. Line faults, such as short circuit and wire off, can be determined by using different input voltage values.
Appendix C 1715-IB16D Digital Input Module Diagnostics By considering these two components—EOL resistor values and the threshold values, we can arrive at the diagnostic settings for the module.
1715-IB16D Digital Input Module Diagnostics Appendix C Threshold Diagnostics Settings There are three types of threshold diagnostics settings to choose from in the Logix Designer application: • Full Diagnostics Configuration • None Diagnostics Configuration • Custom Diagnostics Configuration Full Diagnostics Configuration Selecting Full in the Diagnostics pull-down menu loads a set of threshold default values into the threshold settings. This must be selected if an EOL is used.
Appendix C 1715-IB16D Digital Input Module Diagnostics For a full-diagnostics setting configuration, use these resistor values. IMPORTANT These are the most common commercially-available EOL devices. Table 60 - Full Diagnostics Resistor Values Item Value R1 15 k(1%) - power 0.5 W (max power dissipated 0.128 W) R2 3.9 k(1%) - power 0.5 W (max power dissipated 0.
1715-IB16D Digital Input Module Diagnostics Appendix C Custom Diagnostics Configuration For custom diagnostics, the threshold values are calculated and entered by the user. To calculate the desired values, see Calculate Threshold and Resistor Values on page 276. Once calculated, follow these steps to enter the settings. 1. From the Diagnostics pull-down menu, choose Custom. 2. Click Edit from the Custom Thresholds column. 3. Enter the desired value ranges into the Threshold dialog boxes.
Appendix C 1715-IB16D Digital Input Module Diagnostics Calculate Threshold and Resistor Values To arrive at the correct diagnostic settings, the user must know one of the two values—either the threshold values or the resistor values, and then calculate the other set of values from the known values. The following example shows a typical EOL arrangement for an Emergency Shutdown Device.
1715-IB16D Digital Input Module Diagnostics Appendix C Calculate the Voltage for Off/On Conditions for Threshold Values The following examples calculate the voltage for an ‘off ’ condition with the switch opened and closed. Open Switch/Off Condition With SW1 open, current flows through R1 and R2 (15 + 3.9 k18.9 k. We can calculate the voltage that is present at the input of the input module and by using a voltage divider circuit, we can calculate the voltage for an ‘off ’ condition.
Appendix C 1715-IB16D Digital Input Module Diagnostics If 5.1V is present, we know the switch is in the off position. We can enter a range into the threshold that lets 5.1V to be an off condition. We used 3.0 …6.5V as the range. So, if the voltage drops below 3.0V, it is considered a wire off. If it goes above 6.5V, it is considered indeterminate. 6.5 6.0 5.1V Falls Within The Range 3.5 3.
1715-IB16D Digital Input Module Diagnostics Appendix C Closed Switch/On Condition If SW1 is closed, then current only flows through R2, so to calculate the voltage present at the input module, use the R2 value of 3.9 kRtotal Figure 76 - Closed Switch/On Condition Solution For Voltage +24V dc 15k Termination Assembly SW1 R1 5.1K 4.99kΩ 3.
Appendix C 1715-IB16D Digital Input Module Diagnostics If 13.6 V is present, the switch is in the on position. A range can be entered into the threshold value that lets 13.6V be an on condition. We used 19…10.5V as the range. So, if the voltage drops below 10.5V, it is indeterminate and if it goes above 19V, it is a short circuit. 19 18.5 11 10.5 280 Rockwell Automation Publication 1715-UM001C-EN-P - March 2014 13.
1715-IB16D Digital Input Module Diagnostics Appendix C Calculate On/Off Condition for Resistor Values If a threshold value is set and we wanted to figure out which resistors to use, we can follow these examples. On Condition For an on condition, use the following formulas. In this case, the module load is 5.1 kand the supply voltage is assumed to be 24V DC. So, for this example, use Figure 77 and choose 13V DC, because it is a value within the range in the threshold tables.
Appendix C 1715-IB16D Digital Input Module Diagnostics 45682 45683 4.3kis a close standard value, so we use 3.9 kwhich changes the voltage slightly, but not enough to cause the range to change.
1715-IB16D Digital Input Module Diagnostics Appendix C Off Condition For an off condition, we need to add a new resistor to the formula. We already know R2 is 3.9 kso we can use that, too. 5 V DC +24V dc Termination Assembly SW1 5.1K R1 4.99kΩ 3.9k R2 50 mA 100Ω Shield (if used) 20Ω Terminal Blocks 45678 OV 45684 In this example, 15.4 kis a close standard value, so we use 15 k, which changes the voltage slightly, but not enough to make us change our range.
Appendix C 1715-IB16D Digital Input Module Diagnostics maintained, it is to recommended a calibration drift check be performed every two years for most applications. Although the purpose of checking the calibration of analog modules is the same for input and output modules, to verify that the module’s accuracy and repeatability is maintained, the procedures involved differ per module.
Appendix D Reconfigure a Module Online Use Ladder Logic to Reconfigure an I/O Module If an I/O module supports reconfiguration, you can reconfigure the module via one of these: • Logix Designer application • A MSG instruction in program logic IMPORTANT Consider these guidelines in SIL 2 applications: • We recommend configuring SIL 2 safety applications offline.
Appendix D Reconfigure a Module Online The Module Properties dialog box appears. 2. Reconfigure the I/O module. 3. Click OK. Reconfigure a Module via Ladder Logic It is sometimes advantageous to change the functional operation of a module in the ControlLogix system automatically via the user program instead of by using the Logix Designer application to reconfigure it. This way, changes in the process can dictate when the reconfiguration takes place rather than you performing that function manually.
Reconfigure a Module Online Appendix D Before the new configuration parameters are sent to the module, you must make sure that their relationship to each other is in a format the module accepts and that the values are within the range the module accepts, otherwise the module can fault or the reconfiguration attempt can fail. IMPORTANT Reconfiguring analog modules via ladder logic can be limited to functions that involve only the changing of values.
