Intelligent Technologies QCPort System Install Manual 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.
Intelligent Technologies QCPort System Install Manual 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. A separate power supply is not required for the user interface.
Intelligent Technologies QCPort System Install Manual 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. Once again, the devices are connected to Channel 0 of the motor controller.
Intelligent Technologies QCPort System Install Manual 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.
Intelligent Technologies QCPort System Install Manual 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. Devices that will communicate peer are the S811 soft start and the user display (DIM).
Intelligent Technologies QCPort System Install Manual 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.
Intelligent Technologies QCPort System Install Manual 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.
Intelligent Technologies QCPort System Install Manual 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].
Intelligent Technologies QCPort System Install Manual 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. This single wire enters and exits the device at one point (two connectors).
Intelligent Technologies QCPort System Install Manual 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: • Grouping IO to utilize the Backplane. • Grouping devices that only use the QCPort Interconnect cable. • Changing media as little as possible.
Intelligent Technologies QCPort System Install Manual 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].
Intelligent Technologies QCPort System Install Manual November 2005 Application Example IT. 24V DC Power Supply Figure 11: Distributed Motor Control Panel In this Distributed Motor Panel application example, there are two types of interconnect media being used.
