Quantum Communication Interface Modules

The Modicon Quantum series has a variety of communication interface modules which are listed and described below.

RIO Modules (CRA/CRP)

–          Quantum RIO head and drop modules use a S908-based networking I/O configuration. Communication is done via single or dual coaxial cabling u to 15,000 feet away. This configuration supports a mix of the following product lines:

  • SY.MAX
  • 200 Series
  • 500 Series
  • 800 Series
  • Quantum I/O

When Quantum RIO is required, the Quantum controller may support up to 31 RIO drops. In a RIO configuration, an RIO head module is connected with coaxial cable to RIO drop modules at each remote drop.

DIO Module (CRA)

–          Quantum DIO is implemented over a Modbus Plus network. The CPU or NOMs module may be the network head via their Modbus Plus ports. The Quantum DIO Modbus Plus drop adaptors are specifically designed to link Quantum I/O modules to the head via twisted pair shielded cable (Modbus Plus). The DIO drop modules also provide the I/O with power (maximum 3A) from a 24VDC or a 115/230VAC source. Each DIO network supports up to 63 distributed drops using repeaters.

Network Option Module (NOM)

–          Quantum NOM modules provide extended communication capabilities for the Quantum system within a Modbus Plus configuration.

Modbus Plus on Fiber Module (NOM)

–          Quantum Modbus Plus on Fiber modules provides connectivity to Modbus Plus nodes by fiber cable without fiber optic repeaters, and allows the creation of a pure fiber optic network or a mixed fiber optic/twisted-pair network (with the use of a 490NRP254 Fiber Optic Repeater).

Ethernet TCP/IP (NOE) Modules

–          Quantum Ethernet TCP/IP modules make it possible for a Quantum controller to communicate with devices on an Ethernet network using TCP/IP – the de facto standard protocol. An Ethernet module may be inserted into an existing Quantum system and connected to existing Ethernet networks via fiber optic or twisted pair cabling.

SY/MAX Ethernet Modules (NOE)

–          Quantum-SY/MAX-Ethernet modules are Quantum CPU network option modules that can be placed in a Quantum backplane to connect to Quantum controllers to SY/MAX devices and applications.

MMS-Ethernet Modules (NOE)

–          Quantum-MMS-Ethernet modules are Quantum CPU network option modules that can be placed in a Quantum backplane to connect Quantum controllers to MMS devices and applications.

InterBus Interface Module (NOA)

–          The Quantum InterBus is the interface module to the InterBus bus. The InterBus bus is a fieldbus network designed for I/O blocks and intelligent devices used in manufacturing. It offers a master/slave topology that permits deterministic I/O servicing over it’s 13 km twisted pair network.

LonWorks Modules (NOL)

–          Quantum NOL modules provide connectivity between a Quantum controller and a LonWorks network, based on Echelon’s LonWorks technology. The NOL module is offered in three models for different transceiver types, and supports three twisted-pair media types with different network topologies or data transfer speeds.

Profibus Interface Module (CRP)

–          Quantum Profibus module is the interface module to Profibus-DP networks. The interface modules use Type A, shielded twisted pair to join inline connectors, with or without service ports and bus terminators.

AS-I Interface Module

–          Quantum AS-i modules provide connectivity between a Quantum controller and AS-i networks. AS-i bus cable is an unshielded flat two-wire link on which communication and power are transmitted to connected devices. The media insulation is self-healing to accommodate junction block removal.

Modicon Quantum Overview: Power Supplies, CPUs, I/O Modules

The Modicon Quantum system is a special purpose computing system with digital processing capabilities. Modicon Quantum is designed for real time control in industrial and manufacturing applications in a module, expandable architecture employing the following modules.

–          Power Supply

–          CPU

–          I/O

–          I/O Network Interface

–          Intelligent/Special Purpose I/O

–          Simulator (XSM)

–          Battery

–          Backplanes

–          CableFast Cabling

Quantum Power Supplies are used to supply system power to all modules inserted into the backplane, including CPU modules, Interface modules, and I/O modules. Depending upon the system configuration, the option exists of using the power supply in three different modes. The three modes are:

–          Standalone: For 3A, 8A, or 11A configurations that do not require fault tolerant or redundant capabilities.

–          Standalone Summable: For configurations consuming more than the rated current of one supply, two summing power supplies can be installed on the same backplane.

–          Redundant: For configurations requiring power for uninterrupted system operation. Two redundant power supplies are required for redundancy.

The Quantum CPU is a module residing on the Quantum local I/O backplane. The CPU is a digitally operating electronic system, which uses a programmable memory for the internal storage of user interactions. These instructions are used to implement specific functions such as logic, process sequencing, timing, coupling, and arithmetic. These instructions allow control through digital and analog outputs, for various types of machines and processes.  The Quantum CPU serves as a bus master controlling the local, remote, and distributed I/O of the Quantum system.

Quantum I/O modules are electrical signal converters that convert signals to and from field devices to a signal level and format, which can be processed by the CPU such as limit switches, proximity switches, temperature sensors, solenoids, and valve actuators. All I/O modules are optically isolated to the bus, ensuring safe and trouble-free operation. All I/O modules are also software configurable.

Control Techniques Unidrives and Environmental Responsibility

 

Control Techniques is committed to minimizing the environmental impacts of their manufacturing operations and of their products throughout their life cycle. To this end, they operate an Environmental Management System (EMS) which is certified to the International Standard ISO 14001. Further information on the EMS, their Environmental Policy, and other relevant information is available on request or can be found at www.greendrives.com.

The electronic variable-speed drive manufactured by Control Techniques (such as the Control Techniques UNI1405) have the potential to save energy and reduce raw material consumption and scrap throughout their long working life through increase machine/process efficiency. In typical applications, these positive environmental effects far outweigh the negative impacts of product manufacture and end-of-life disposal.

Nevertheless, when the products eventually reach the end of their useful life, they can be very easily dismantled into their major components for efficient recycling. Many parts snap together and can be separated without the use of tools, whilst other parts are secured with conventional screws. Virtually all parts of the product are suitable for recycling.

Product packaging is of good quality and can be re-used. Large products are packaged in wooden crates; whilst smaller products come in strong cardboard cartons which themselves have a high recycled fiber content. If not re-used, these containers can be recycled. Polyethylene, used on the protective film and bags for wrapping product, can be recycled in the same way. Control Techniques’ packaging strategy favors easily-recyclable materials of low environmental impact, and regular reviews identify opportunities for improvements which are consistently being made.

When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.

MRO Electric and Supply has new and refurbished Control Techniques products available. We also offer repair pricing. For more information, please call 800-691-8511 or email sales@mroelectric.com.
