Chapter 2 Designing Cable Systems When designing DeviceNet systems, it is necessary to consider the following (refer to publication DNET-UM072_-EN-P for additional requirements): Number of nodes does not exceed 64, with three nodes reserved for scanner (node 00), PC (node 62), and new device (node 63).
2-2 Designing Cable Systems Medium Voltage Controller Cable System Construction Do not apply high voltage to any installed DeviceNet cable system or its connectors. The high voltage will destroy internal capacitors in the connectors.
Chapter 3 DeviceNet Cable System Layout for Medium Voltage Controller Structures The DeviceNet trunk line assembly is mounted in a 6 inch by 6 inch low voltage wireway, which is mounted on the top of the main structure. (Refer to Figure 3.1). NOTE It may be necessary to remove the low voltage wireway, to prepare the structure for shipment.

Chapter 4 Linking DeviceNet Communication Cables in Medium Voltage Controllers Figure 4.1 – Joining the DeviceNet Trunk Line in Adjacent MV Sections Connecting DeviceNet within MV Controller Line-up General This section describes the recommended procedure for connecting DeviceNet communication cables (trunk lines) in MV controllers. The number of and type of sections shown above is arbitrary and for illustration purposes only. Drawings are not to scale.
4-2 Linking DeviceNet Communication Cables in Medium Voltage Controllers 3. When joining new sections to an existing MV MCC, remove the terminating resistor from the original end section (the one to which new sections were just joined). Install the terminating resistor according to the information supplied in the section ― Terminating Resistors‖ and ― Installing Terminating resistors‖ . 4. When new sections are added, always do the following design calculations: Check the total number of nodes.
Linking DeviceNet Communication Cables in Medium Voltage Controllers 4-3 1. Determine the safest and most convenient place to access the DeviceNet cable terminating point in the remote equipment. Drill the necessary cabinet or cover plate opening. Terminate the DeviceNet cable at the MV controller line-up in the LV wireway using the chetmag at the rightmost section or at the leftmost section.
4-4 Linking DeviceNet Communication Cables in Medium Voltage Controllers Re-location of Termination Resistors General If any MV controller units are relocated such that the termination resisters are no longer at the end of the trunk line, then they must be removed and re-installed at the end of the lineup. A unit that is added to either end of the lineup must also have the termination resister relocated from the existing end unit to the added unit.

The appropriate location for terminating resistors is shown for reference. 121Ohms DeviceNet Scanner LV MV LV MV LV MV LV MV LV MV LV MV LV MV LV MV You must attach a terminating resistor of 121 ohms, 1%, 1/4W or larger, to each end of the trunk line.

Chapter 6 DeviceNet Power Supply I MPORT ANT The DeviceNet cable system requires a 24Vdc power source to operate. The power supply must: • Meet NEC Class 1 requirements as outlined in Article 725 • Be DeviceNet compatible as specified in the ODVA requirements Power supplies that do not satisfy both points listed above can result in damage to the DeviceNet signal and components, as well as failure to comply with NEC, local codes, and inspection.
6-2 DeviceNet Power Supply Note: Optional equipment is also shown. Figure 6.1 – LV Panel of Incomer with DeviceNet Power Supply Network Grounding at the Power Supply The DeviceNet cable must be grounded at only one location. The ideal choice is at the power supply. Ground the power supply and 24 Vdc common (black wire).
DeviceNet Power Supply 6-3 Connecting Two Power Supplies When an additional 24 Vdc Class 1 power supply must be installed for MV controller line-ups, the red trunk conductor between the power supplies must be broken. Locate a linking connector between sections and disconnect the red conductor (refer to the following figure). Ground only ONE of the two power supplies. break Red V+ White CAN_H Blue CAN_L Black V- (common) Power Supply Power Supply Figure 6.

7-2 System Commissioning and Software Installation System Commissioning Checklist When installing a DeviceNet MV controller line-up, use the following checklist before applying power to the network: DeviceNet Software Installation checklist Number of nodes does not exceed 64, with three nodes reserved for scanner (node 00), PC (node 62), and new device (node 63) Individual drop lengths do not exceed 20 feet (6 m) Cumulative drop length does not exceed the desired network baud ra
System Commissioning and Software Installation 7-3 5. Use RSNetworx for DeviceNet to program and configure devices (e.g., full load current, acceleration rate, etc.). Do not download to a device before uploading from that device. Otherwise, the node and baud rates will be overwritten, requiring each device to be individually manually reprogrammed. Make sure to set communication-loss behavior for each device.

Chapter 8 Filling a Prepared Space in a MV Controller Line-up with DeviceNet General Use this section when upgrading a Bulletin 1500 prepared space in a DeviceNet MV controller with a controller kit. Each DeviceNet component is factory wired within the controller kit and has a communication cable that plugs into the device on one end and the other end plugs into a DeviceNet port located on the flat vertical cable assembly mounted on the left side of the low voltage panel.

The prepared space does not have any DeviceNet connections or any DeviceNet wiring entering or crossing the unit.
8-4 Filling a Prepared Space in a Medium Voltage Controller Line-up with DeviceNet Software Update After installing a controller kit in an IntelliCENTER MV line-up, the user must update the IntelliCENTER software by following these directions. This is done by merging the data disks for the controller kit(s) with the existing IntelliCENTER database. Please refer to the IntelliCenter software manual 2100-UM002_-EN-P.
Appendix A How to Find Electronic Data Sheets (EDS) Background After installing IntelliCENTER software, an Electronic Data Sheet (EDS) file must be registered for each unique device in the MCC. This section details how to perform that task. Definition of EDS Files EDS files are simple text files used by network configuration tools— such as DeviceNetManager™, RSNetworx, and IntelliCENTER software—to help identify products and easily commission them on a network.
A-2 How to Find Electronic Data Sheets (EDS) Finding EDS Files for Other Devices 1500-IN057C-EN-P – June 2013 The program CD also contains a directory called EDS. This directory contains all EDS files sorted by the product family or classification. EDS files can be obtained at http://www.ab.com/networks/eds.
