Page 6: Interconnectivity Using Qcport
November 2005 Interconnectivity Using QCPort Introducing QCPort The interface demands on control devices continues to increase at a rapid pace. An intelligent control device requires connection to configuration and monitoring tools, operator interfaces, and other peripheral devices, as well as the option to connect to a variety of industrial fieldbusses. -
Page 7: Example Of Qcport Use
November 2005 Examples of QCPort Use One Device Using QCPort In many applications, the QCPort will be used as the connection between a motor controller and the user interface/configuration keypad. The following figure contains a one-to-one solution, where the user interface is powered from the motor controller’s QCPort. -
Page 8: Figure 2: Example Of Multiple Peripherals On One Device Using Qcport
November 2005 Multiple Peripherals on One Device Using QCPort QCPort has been designed to support multiple devices connected to one motor controller, without the motor controller having prior knowledge of the connected device. Devices that can be connected to a motor controller include user interface products and IO products. -
Page 9: Multiple Devices Being Controlled And Monitored Remotely Using Qcport
November 2005 Multiple Devices Being Controlled And Monitored Remotely Using QCPort When an industrial fieldbus adapter is used within a system, the adapter will act as a subscanner presenting the QCPort devices as IO to the industrial fieldbus. This allows the QCPort devices to be monitored, controlled, and configured from a remote location. -
Page 10: Qcport Operating Modes
November 2005 QCPort Operating Modes Overview The QCPort system is capable of two operating modes: • Master-Slave • Peer When the system is intended to be used in a master-slave setting there is no configuration necessary other then setting the address (group ID) of each device to a unique address Peer devices require a configuration setting for normal operation. -
Page 11: Overview Of Qcport Interconnect System
November 2005 Overview of QCPort Interconnect System Device Connection in a QCPort System Devices are connected into a QCPort system using one of the following connection types—either a backplane or interconnect cabling. Both of the connection types provide for communication and power. The entire QCPort system, using QCPort pre-manufactured interconnects, cannot exceed 100 feet [30 meters] in total length. -
Page 12: Figure 6: Qcport Interconnect Cable
November 2005 QCPort Interconnect Cable QCPort Interconnect cable provides a convenient way to connect QCPort devices that are not mounted directly next to one another or where a Backplane could be used. The QCPort Interconnect cable is ordered from the factory at preconfigured standard lengths. QCPort devices provide two QCPort interconnect cable plug connections that are in parallel, so that the devices can be daisy chained together. -
Page 13: Figure 8: Long Run Cable Connection
November 2005 Long Run Cable In applications that require connections between devices that are greater than 10 feet [3 meters] apart, or greater current carrying capacity is needed than the interconnect cable supports, a “long run” cable should be used. This cable provides data and 24V DC power connections up to 1000 feet [300 meters]. -
Page 14: Daisy Chain
November 2005 Planning a QCPort Topology QCPort is a RS485 based system and allows only two topologies; they are daisy chain and trunk drop. Connecting QCPort in a star is not allowed since it will produce unreliable communication. Daisy Chain A daisy chain topology consists of a single wire that connects devices. -
Page 15: Physical Placement
November 2005 Methods of connection include using QCPort Interconnect Cable, QCPort Backplane, Long Run, or any combination of the three. Physical Placement When planning the connection, care should be taken as to the physically placement of the devices. Considerations include: •... -
Page 16: Using Biasing Resistors
November 2005 Using Biasing Resistors Depending on the type of QCPort system being implemented, biasing resistors may or may not be required. For Figure 1 and Figure 2 under the “Interconnectivity Using QCPort” section (One Device Using QCPort), a single biasing resistor is required when the total length of the system is less than 3 feet [1 meter]. -
Page 17: Application Example
November 2005 Application Example Figure 11: Distributed Motor Control Panel In this Distributed Motor Panel application example, there are two types of interconnect media being used. The IO and Network Adapter use the Backplane Interconnect while the motor starters use the QCPort Interconnect cables. In this example, the QCPort power is supplied through the D77E-QPLR biasing resistor (last module), and the change from the backplane to the QCPort Interconnect cable is performed there as well. -
Page 18: Planning A Qcport Interconnect System
November 2005 Planning a QCPort Interconnect System Guidelines for Supplying Power Use the following guidelines to protect your devices and achieve the best results when supplying power to the QCPort interconnect system. IT. Power Supplies The IT. family of products includes power supplies that meet the needs of the QCPort devices and motor control. -

November 2005 Table 3: RJ Interconnect Maximum Current QCPort Interconnect Cable 10 [25] inch [cm] 3 [1] feet [meter] 6 [2] feet [meter] 10 [3] feet [meter] The voltage range between +24 and G must be between 18 and 28V DC. Locating a Power Supply The QCPort interconnect system allows several options for supplying power, as outlined in this section. -
Page 20: Power Supply
November 2005 1 Power Supply Locate the power supply at the end, middle, or anywhere along the cable, as illustrated in the following figure. Biasing resistor Power Supply Figure 12: 1 Power Supply Grounding the Interconnect System You must ground the QCPort system at only one location. If you use more than one power supply, all of them should be attached to the same earth ground. -
Page 21: Sizing A Power Supply
November 2005 Sizing a Power Supply It is important to verify that the power supply is properly sized for the load and the length of the QCPort system. To calculate if the placement and the size of the power supplies are adequate, refer to the examples in the Using the Sizing Calculation on page 23. -
Page 22: Sizing Calculation
November 2005 Sizing Calculation A power supply that is not end connected creates two sections of cable. Because of this, each section needs to be evaluated separately. The equation sums the calculated drop for each device and compares it to 4.65V. SUM {[(L x Rc) + (N x (0.005))] x I... -
Page 23: Using The Sizing Calculation
November 2005 Using the Sizing Calculation The following examples use the sizing calculation to determine if the power supply is placed correctly in the system and if the power supply is large enough for the application. Example 1 End Connected Power Supply 1 foot 1. -

Page 26: Appendix A: Using Long Run Cables
November 2005 Appendix A: Using Long Run Cables When devices require locating further than 100 feet [30 meters] from one another, the physical media changes from QCPort Interconnects to Long Run cables. This cable is better rated for current carrying capacity and for the RS485 communication. When connecting between Long Run and a QCPort device, the D77E-QPLR is required to change the physical media. - Page 27 November 2005 1. Find the voltages for each node using the equation for Long Run. SUM {[(L n x (0.0045)) + (N t x (0.005))] x I n } <= 4.65V Device 1 [(18 x (0.021)) + (1 x (0.005))] x 1.0 = 0.383V Device 2 [(36 x (0.021))+ (2 x (0.005))] x 0.5 = 0.383V Device 3 [(43 x (0.021)) + (3 x (0.005))] x 0.4 = 0.367V Device 4 [(95 x (0.021)) + (4 x (0.005))] x 0.3 = 0.604V...
