Dimensions 80 mm (3.15 in) 136 mm (5.35 in) 152 mm (5.98 in) Power Connection To comply with the CE Low Voltage Directive (LVD), this equipment must be powered from a source compliant with Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV). To comply with UL restrictions, this equipment must be powered from a source compliant with Class 2 or Limited Voltage/Current.
Chapter 1 Installation We recommend a 24…32V DC power supply for the linking device to operate correctly. No additional power supplies or power conditioners are required. The power supply connection is described here. Tighten DC Power connections to a torque of 0.22…0.25Nm (2…2.2 lb-in). IMPORTANT Do not use extra power supplies or power conditioners with the 1788-EN2PAR and 1788-CN2PAR linking devices. PA Network Connections The PA network must be connected via the PA terminal on the linking device.
Installation Chapter 1 The PA network connections are described here.
Chapter 1 Installation ControlNet and EtherNet/IP Connections Two BNC (Bayonet Neill-Concelman) connectors on the base of the 1788-CN2PAR linking device provide connections for single or dual ControlNet media. The dual port EtherNet/IP switch provides connections for multiple EtherNet/IP topologies, including device level ring (DLR). The EtherNet/IP port can also be used as a connection point in the field to access the Web server or asset management tools. The ControlNet connections are described here.
Installation IMPORTANT Chapter 1 If the shield is not correctly connected, noise from the environment on the PA bus can cause the PA data to be corrupted. Corrupted data can result in a low success rate and device connections being lost. Section 12.8.5 of IEC61158-2 (Physical Layer Specification), indicates that 90% of the full length of the cable must be shielded. See Grounding/Earthing on page 19 for more details for shield connections.
Chapter 1 Installation Cable Path Do not route the PROFIBUS PA cable near any motors or high-voltage/ high-current cables. Motors and high-voltage/high-current cables can generate noise that decreases communication signal quality on the PA cable, which can corrupt PA packets and cause field device timeouts. Cable Lengths Load and voltage drop determine maximum cable length.
Installation Chapter 1 Cable Type and Minimum Requirements Per section 12.8.2 of IEC61158-2 (Physical Layer Specification), the PROFIBUS PA cable must meet the following minimum requirements: • Impedance at 31.25 kHz of 100 Ω ± 20% • Maximum attenuation of 3 dB/km • Conductor cross-sectional area of 0.8mm2 (18 AWG) • Shield coverage of at least 90% • Maximum DC resistance of 24 Ω/km per conductor • Maximum capacitive unbalanced to the shield of 4nF/km Cable Color Coding Per section 12.8.

Right-click the linking device and choose Properties. 2. Click the Configuration tab to open the configuration page for the linking device. Process Catalog Launches the HSProcessUtility that manages the GSD files and DTMs.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application Download Downloads the configuration to the linking device. The linking device saves the configuration in non-volatile memory. IMPORTANT After the configuration has been downloaded to the linking device, cycle power for the new configuration to take effect. Upload Uploads the configuration from the linking device to the Studio 5000 Logix Designer project.
Set Up in the Studio 5000 Logix Designer Application Configure the PA Master Chapter 2 Topology Mode Choose the correct topology mode for the application. The graphical representation must match the actual topology. See Appendix B for available options. Use this setting to configure redundant linking devices, redundant PA media, and the internal PA segment terminators. PA Node The PA master (linking device) needs a node number to operate on the PA bus. The default is node number 1.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application Configure the Field Devices This section describes how to configure one PV and multiple PVs for a slot. Configure PV with Single Format Each field device can have multiple PVs, each with a different format. In most cases the default configuration correctly configures each PV, but if you add, remove, or change PVs, make sure to change the format if needed. Table 2 shows available PV format options.
Set Up in the Studio 5000 Logix Designer Application Chapter 2 Configure PV with Multiple Formats In some cases (for example, positioner field devices), there are multiple input and output PVs per slot. See Valve Positioner Configuration on page 34 for details. IMPORTANT Select the number of inputs and outputs, and their respective PV formats, as shown in the user manual of the field device. In the input image of the field device, the PV is set per the manual slot configuration.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application Valve Positioner Configuration A valve positioner typically has only one slot that has multiple predefined inputs and outputs. Consult the user manual for the device to verify the definition for each option. One basic option is to configure the valve positioner to receive a setpoint from the ControlLogix controller via the linking device and to return the defined position. Follow these steps for setting the valve positioner. 1.
Set Up in the Studio 5000 Logix Designer Application Chapter 2 4. Configure the input and output formats for the slot configuration. IMPORTANT See the documentation for the valve positioner to verify the correct data format for each option. In this example, the setpoint sent to the valve positioner is a real value with a 1-byte status. The actual position that the valve positioner returns is also a real value with a 1-byte status, with an added 1 byte with status and discrete position. 5.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application PROFIBUS PA Redundancy Setup The linking device provides PROFIBUS PA and Ethernet architectures. This section describes the PROFIBUS PA redundancy options that are available, and highlights the benefits and sets required to implement them. Hardware This section describes the hardware redundancy for media and master devices. Media Redundancy For media redundancy, you can select from dual trunk or ring redundant media architecture.
Set Up in the Studio 5000 Logix Designer Application IMPORTANT Chapter 2 When using ring redundancy, enable the auto-terminate function on the 1788PARJB junction box. See the1788-PARJB Quick Start Guide, publication 1788QS005, for details. Failure to enable the auto-terminate function can cause network termination issues that can cause the network to become unstable. Limitations The linking device can support a maximum of 24 field devices and a maximum current supply of 500 mA per trunk.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application Master and media redundancy can run simultaneously as shown in Figure 5. Figure 5 - MultiMaster and Media Redundancy More junction boxes can be added to the dual trunk. See Appendix B for valid redundancy configurations. IMPORTANT When using dual trunk architecture, use the 1788-PARJB junction box. Limitations A maximum of two linking devices can be added to one network.
Set Up in the Studio 5000 Logix Designer Application Chapter 2 Software IMPORTANT Choose the architecture that is used in the field before downloading the configuration. If the incorrect architecture is chosen, the network will not function correctly. Media Redundancy If the dual trunk redundancy is selected, you can view the PA Bus, and Channel A and Channel B diagnostics (voltage, current, and so on) as shown in Figure 6.
Chapter 2 Set Up in the Studio 5000 Logix Designer Application A short on either bus is indicated in the Studio 5000 Logix Designer application, or in the AOP as shown in Figure 7. Figure 7 - Bus Short/Open Circuit IMPORTANT The linking device can only detect a short/open circuit on either of the trunks that are connected directly to the linking device. If there is a fault between two junction boxes, you will only see the fault by examining the junction boxes in the field.
Set Up in the Studio 5000 Logix Designer Application Chapter 2 MultiMaster Mode When running in redundant master mode (MultiMaster mode), the PA master can be in one of three different states: • Primary Active • Secondary Active • Master Config Mismatch • Master Node Mismatch Primary Active The Primary Active linking device is the primary master that is currently providing communication. Secondary Active The Secondary Active linking device is the secondary master (hot backup).
Chapter 2 Set Up in the Studio 5000 Logix Designer Application Master Config Mismatch The Master Config Mismatch state occurs when the PA master configuration does not match the other PA master on the PA network. IMPORTANT Both masters must have the same master and field device configurations. Master Node Mismatch The Master Node Mismatch state occurs when the primary and secondary masters do not have the same node address.
Set Up in the Studio 5000 Logix Designer Application Redundant PA Code Example Chapter 2 When running in MulitMaster mode, the data appears twice in the Logix controller (once for each PA master). A combination of PA master status, MulitMaster active, and field device connection statuses are used as criteria. The example code in Figure 8 provides an AOI to control the redundant PA.
