The trunkline is the “backbone” of your network. Drops serve as physical connection mechanisms to the trunkline. Drop length up to 20 feet. There are 4 types of cables: Thick, Flat (KwikLink) , Thin cable and Class 1 drop cable. Thick, Flat and Class 1 drop cables are rated for 8 amps of current. Class 2 thick cable, only 4 amps in North America. Thin cable is rated for 3 amps of current Thick, Flat and Thin cable can be used for “Trunk” Class 1 drop cable is designed only for drops.Cable Budgets - Thick TrunkCable Budgets - Thick TrunkData Rates 125 Kbits/sec 250 Kbits/sec 500 Kbits/sec Trunk Distance 500m / 1640ft 250m / 820ft 100m / 328ft Max.

Each unit allows another maximum length of cable to be added to either the trunk or drop lines of a network. For thick, round media, that would mean another 500 meters per unit. Multiple units can be used to extend the trunk or drop even more. This unit can also convert to fiber optic for outdoor or high noise areas. The units cost around $300 each and have become very popular. Note: These units store and repeat, which means they will ACK packets on the local network and retransmit them on the remote network. This will impart a small network delay of .5ms, along with the amount of time a retransmit the packet, when doing performance calculations. Mixing Media on the TrunkMixing Media on the TrunkAlways use the cable limits of the lowest distance media in the mix for the entire network. In other words if you use flat and thin media then use the max trunk line distance for the thin media for the whole network. If you use thick and flat media in a mix, then use the maximum trunk length of the flat media for the whole network. It doesn't matter whether there is much smaller length of the lower distance cable compared to the higher distance cable on the network. To avoid doing some complicated, risky calculations, just use the "weak link theory" and spec out the max distance of the lower distance media. When combining Flat media and any other shielded media. Connect the shield wire of the shielded media to the V- wire of the Flat media, when making that transition. Remember to only ground the V- wire at only one location in your network.Wireless Modems on DeviceNetWireless Modems on DeviceNetThese modems act as invisible wireless connections between the Device Net networks they are attached to. They are very useful for moving machinery, where cable connections are not feasible. They are best for line of sight applications without a lot of building steel separating them. Matric will be coming out with a next generation modem during Summer 2002 which will have improved radio signal transmission and reception.Connector Fun FactsConnector Fun FactsOpen style Phoenix connector selections.

This is especially important when DeviceNet is used in Motor Control Centers. All components, both trunk cable and drop cable, must be Class 1 rated for the entire system to be Class 1. Class 1 rated media available from Rockwell is KwikLink original trunk cable, Class 1 drop cable assemblies (See pictures below) and spools of Class 1 round trunk and Class 1 round drop cable. Up to 8 amps of current can be drawn through Class 1 round trunk and drop cables. Cable Catalog Number Class Shield Comment Belden According to NEC regulations (North America Only), Class 2 Installations can only be in the vicinity of up to 300 Volts, but no higher. Class 2 cable systems can carry no more than 100 Watts. So doing a calculation of 100 Watts/24 VDC = 4.16 amps of maximum allowable current in a Class 2 cable. The 1787-DNPS and 1606-XLSDNET4 power supplies are specifically designed to be used on Class 2 cabling systems.nullDeviceNet Power SuppliesThe 1787-DNPS is a Class 2 rated, ODVA compliant Power Supply capable of 4 amps of current at 24VDC. The 1606-XLSDNET4 is also a Class 2, ODVA Compliant power supply with the ODVA compliancy checkmark. Rated for 4 amps at 24VDC The 1606-XLSDNET8 is a Class 1, ODVA Compliant Power Supply with the ODVA compliancy checkmark. Rated for 8 amps at 24VDC. Important Note: The 1606-XLDNET4 and 1606-XLDNET8 Power Supplies are NOT ODVA compliant or marked. The 2100-DNBPS redundant power supply is used to power devices that get their power from the DNet network, such as the E3 overload. This supply can either get power from the DeviceNet network power or an external AC power source. It is handy if a device can not be powered down with the network power. Publication 2100-TD022A-EN-P describes this power supply in more detail. 1606-XLSRED is a redundant power supply that gets its input from two different 24VDC power supplies. It’s output is 24VDC and will still be powered if either of the power input power supplies are operational. It is still recommended to use 1606-XLSDNET4 or 1606-XLSDNET8 DeviceNet compliant power supplies as the input power to this unit. 1787-DNPS1606-XLSnullDeviceNet Power Supplies Cont.The 2100-DNBPS is a 24VDC power supply used specifically in MCC enclosures to provide back up power to the E3 overload, Bulletin 100 DSA and other power products that get their entire operating power from the DeviceNet cable. The 2100-DNBPS gets its operating power from either a 110VAC or 220VAC power connection and supplies 24VDC at 250 ma. It is used so if the DeviceNet power is interrupted, this supply will take over and supply power to the device which allows the E3 overload to continue to protect a motor or have it’s outputs stay energized even after a DeviceNet power interruption occurs. The 2100-DNBPS is available for sale via PASSPORT through the LVMCC Business.

There is a new KwikLink General Purpose connector available catalog number 1485P-K1E4-R5 is a smaller, less expensive connector that comes in a micro style version only. This connector can be used with all three KwikLink trunk line cables. Environmental Rating is IP67 only. Original KwikLink connector environmental rating is IP67, NEMA 6P, 1200psi washdown. Standard class 2 KwikLink drop cables are only rated for 3 amps at 24VDC. Class 1 drop cables rated at 8 amps are also available with a raw cable end or a mini female pin, connector. Class 1 drops are NOT available to a micro style connector since the connector is not rated for 8 amps. KwikLink Radiated Immunity Testing Publication Number 1485-WP001A-US-P gives details on how KwikLink cable, without a shield, can still be highly noise immune. Some of the Kwiklink interface tops with date codes 04300 to 05200 may have intermittent connections when installed. This problem will only show up at installation and the tops, not the bases should be replaced, if this problem is seen.
