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. At the same time, the intelligent devices continue to shrink in size and cost, forcing distribution of the field connections that once were native on the devices.

QCPort is a flexible interface port that integrates the many connectivity needs of the intelligent device into a single device port for the means of control, setup, and configuration. The integration of these capabilities provides interface options that are powerful and cost effective. In addition to the interface functionality of QCPort, care has been taken to insure that systems that connect via QCPort are simple to configure, connect, and maintain.

QCPort Physical Characteristics

In an effort to use existing proven technology, QCPort uses the RS485 physical layer. This physical layer is common to many industrial communication interfaces and has a long and proven track record within industrial applications. QCPort is a four-wire system where there is an A and B for signal and a +DC and Ground for device power. Depending on the type of device interconnect and the distance between devices, there are many choices for the type of interconnect physical media; these choices will be discussed further in the manual.

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. In this example, the user interface is connected to Channel 0 of the motor controller. Channel 0 is specifically used for connection to the user interface and operator stations.

Intelligent Technologies QCPort System Install Manual

Figure 1: Example of One Device Using QCPort

The interconnect supplied with the operator interface connects the operator interface to the motor controller. This connection provides for 24V DC and communication; the operator interface is powered from the motor controller. Configuration of the operator interface or the motor controller for this application is not required for communication to be established. The user can then use the operator interface to configure the motor controller parameters, operate the motor controller, and monitor the operation of the motor controller.

The information contained within this manual does not include instructions for setup or operation of the motor controller or operator interface. For instructions on how to apply the operator interface, refer to the manual for that device.

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 u ser interface products and IO products. Once again, the devices are connected to Channel 0 of the motor controller.

The figure below illustrates an application example that includes a user interface and IO modules. The input module is used to apply a hard-wired HOA while the output module is used to annunciate the motor controller status and trip conditions. The mapping of the data between the motor controller and the IO devices does not require a tool and is seamless to the user.

Figure 2: Example of Multiple Peripherals on One Device Using QCPort

When multiple devices are connected to one motor controller, the user has to be aware of the power demand of all of the peripherals. Verify the power requirement of this system by adding up the power demands of the peripherals to see if they exceed the power capacity of the motor controller. If the power capacity of the motor controller is exceeded, a power supply is required for QCPort. To help size the power supply, consult “Locating a Power Supply” later in the manual.

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. For this type of application, a power supply will be required; it can be the same power supply that is used for the motor controllers.

Power Supply

Figure 3: Example of Remote Connection Using QCPort

Since a power supply sizing is required, refer to “Locating a Power Supply” later in this manual. Along with the power supply sizing, physical media restrictions must be followed. This includes the length of the interconnects, type of interconnects, and the power capabilities for the interconnects.

This type of application requires some configuration. The Group IDs for the QCPort devices need to be set to unique IDs, the adapter requires an address configuration, and then the mapping feature needs to be invoked to map the QCPort data to the industrial fieldbus. None of these configuration requirements require a software tool. If advanced configuration of the QCPort devices is required, then a software tool or a QCPort user interface will be required. For information on configuration of the QCPort devices, refer to the user manual for those devices.
