Page 7: Understand Standalone And Redundant Control
ControlLogix ControlNet Interface Module 7 Understand Standalone and Redundant Control You can use the 1756-CNB and 1756-CNBR Series E modules as standalone or in firmware version 11.xx as redundant control. For standalone control, only one set of modules is required. For redundant control, two ControlLogix chassis are populated with identical pairs of modules called partners. -
Page 8: Before You Begin
8 ControlLogix ControlNet Interface Module Before You Begin Before you install the module you need to make sure you: • Know how to handle the module. Refer to the section Prevent Electrostatic Discharge. • Have all of the necessary components: 1756-CNB or 1756-CNBR 1756-PA72/75 or 1756-PB72/75 1756-A4, 1756-A7, 1756-A10,... - Page 9 ControlLogix ControlNet Interface Module 9 All 1756-CNB and 1756-CNBR modules are keeper-capable, as listed. 1756-CNB and 1756-CNBR Major/Minor Revision Keeper Type 1.xx Single-keeper 2.xx Multi-keeper 3.xx Single-keeper 4.xx Multi-keeper 5.xx Multi-keeper 7.xx Multi-keeper 10.xx Multi-keeper 11.xx Multi-keeper You must match the keeper to the type of network, or upgrade the firmware of the module at MAC ID 01 to be multi-keeper capable.

- Page 11 ControlLogix ControlNet Interface Module 11 Set the Module’s Network Address Switches Use your fingers or a small screwdriver to set the module’s network address switches. For modules in a standalone chassis, you must specify a unique ControlNet network address; for modules in a redundant chassis, you must specify the same address for the secondary module that you specified for the corresponding primary module.
- Page 12 12 ControlLogix ControlNet Interface Module Prepare the Chassis for Module Installation Before you install the module, you must install and connect a ControlLogix chassis and power supply. A 4-slot chassis with a power supply is shown in the figure Chassis and Power Supply. Chassis and Power Supply Power Chassis...
- Page 13 ControlLogix ControlNet Interface Module 13 Determine Module Slot Location The figure Chassis Slot Numbering shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot and is always the leftmost slot in the rack (the first slot to the right of the power supply). You can use any size ControlLogix chassis and install the module in any slot.

Page 14: Install Or Remove The Module Under Power
14 ControlLogix ControlNet Interface Module Install or Remove the Module Under Power You can install or remove the module while chassis power is applied if you observe the following precautions. When you insert or remove the module while backplane power is on, WARNING an electrical arc can occur. -
Page 15: Install The Module
ControlLogix ControlNet Interface Module 15 Install the Module Align the circuit board with top and bottom guides in the chassis. Slide the module into the chassis. Make Circuit sure the module Board backplane connector properly connects to the chassis backplane The module is properly installed when it is flush with the power supply or other installed modules. -
Page 16: Remove The Module
16 ControlLogix ControlNet Interface Module Remove the Module Upper Tab Push on the upper and lower tabs to disengage them. Then slide the module out of the chassis. If you are replacing an existing module with an identical one, and you want to resume identical system operation, you must install the new module with the same ControlNet address in the same slot. -
Page 17: Connect The Module To The Network
ControlLogix ControlNet Interface Module 17 Connect the Module to the Network You can connect the module to the ControlNet network using a tap (1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS) or a network access cable (1786-CP). If you connect or disconnect the communications cable with power WARNING applied to this module or any device on the network, an electrical arc can occur. - Page 18 18 ControlLogix ControlNet Interface Module When connecting the module to a ControlNet network, you should also refer to the following documentation: • ControlNet Coax Tap Installation Instructions, publication 1786-5.7 • ControlNet Cable System Planning and Installation Manual, publication CNET-IN002 For network connections we recommend taps with a straight connector (1786-TPS or 1786-TPYS) because of the location of the BNC connectors on the bottom of the module.
- Page 19 ControlLogix ControlNet Interface Module 19 Connect to the Network with a Tap Perform the following steps to connect the module to the network using a tap. 1. Remove and save the dust caps from the ControlNet network taps. Do not allow any metal portions of the tap to contact any conductive ATTENTION material.
- Page 20 20 ControlLogix ControlNet Interface Module To prevent inadvertent reversal of the tap connections (resulting in IMPORTANT incorrect status displays requiring troubleshooting), check the tap drop cable for the label indicating the attached segment before making your connection. To work properly, when you use modules in a redundant control chassis pair, the primary and redundant partner modules must be connected to the same network segment.

Page 23: Troubleshoot The Module
ControlLogix ControlNet Interface Module 23 The 1786-CP cable can be plugged into any ControlNet network product’s network access port (NAP) to provide programming capability on the ControlNet network. A programming terminal connected through this cable is counted as a node and must have a unique network address. Use a 1786-CP cable when connecting a programming terminal to the ATTENTION network through network access port (NAP). -
