CompactLogix ControlNet Interface Module Installing the Modules ATTENTION IMPORTANT This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately every 200 mm (7.87 in.) and use end-anchors appropriately.
CompactLogix ControlNet Interface Module 9 4. Use M4 or #8 screws to mount the modules to your panel with 1.16 Nm (10 lb-in) of torque. 5. Ground the module on a ground bus with a dedicated Earth-ground stake. 6. Connect the ground bus to a functional Earth-ground on the DIN rail or panel. Refer to Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information. Install the DIN Rail Mount the DIN rail in a suitable location.

CompactLogix ControlNet Interface Module Connect the Module You can connect the module to the ControlNet network by using a tap (catalog number 1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS) or a network access cable (catalog number 1786-CP). Refer to the ControlNet Coax Media Planning and Installation Guide, publication CNET-IN002, for additional information.
CompactLogix ControlNet Interface Module 15 Set the Network Address Switches Use a small screwdriver to set the module’s network address switches. You must specify a unique ControlNet network address. You can select an address of 01…99.

CompactLogix ControlNet Interface Module Connect to a ControlNet Network The 1768-CNB and 1768-CNBR modules have a network access port (NAP) available. The most common and easiest way to connect to the network is by using the a ControlNet tap. Perform the following steps to connect the module to the network by using a tap. 1. Remove and save the dust caps from the ControlNet network taps. ATTENTION Do not allow any metal portions of the tap to contact any conductive material.
CompactLogix ControlNet Interface Module 17 On 1768-CNBR installations, make sure the correct network is connected to the correct tap connection. Reversing the tap connections will result in incorrect status display. IMPORTANT When you are using redundant media, connect the channel of each partner to the same network segment.
CompactLogix ControlNet Interface Module Connecting a Laptop Computer to the Network with a 1784-PCC Card The 1784-PCC1 cable can be connected from a laptop computer with a 1784-PCC card into any ControlNet product’s network access port (NAP) to provide access to an existing ControlNet network. A laptop computer connected through this cable is counted as a node and must have a unique network address (MAC ID) less than or equal to the maximum unscheduled node (UMAX).
CompactLogix ControlNet Interface Module 19 Connecting a Desktop Computer to the Network with a 1786-CP Cable The 1786-CP cable can be connected from a desktop computer with either a 1784-PCIC or 1784-PCICS card into any ControlNet product’s network access port (NAP) to provide access to an existing ControlNet network. A desktop computer connected through this cable is counted as a node and must have a unique network address (MAC ID) less than or equal to the maximum unscheduled node (UMAX).
CompactLogix ControlNet Interface Module Connecting a Desktop Computer Directly to the ControlNet Network A 1786-TPR, 1786-TPS, 1786-TPYR, or 1786-TPYS cable can be connected from a desktop computer with either a 1784-PCIC or 1784-PCICS card directly to an existing ControlNet network. A desktop computer connected through this cable is counted as a node and must have a unique network address (MAC ID) less than or equal to the maximum unscheduled node (UMAX).
