Molex (USA) provides Brad PC-based network interface cards (NICs) used to connect various computer bus formats, including PCI Express, PCI, PC/104, USB and VME to industrial networks (e.g. CANopen and DeviceNet).
THE DEVICENET NICs INCLUDE SST AND USB INTERFACE MODULES for standard PCI (3,3 V, 5 V) and PC/104 bus formats. The SST family is used in real-time control and data-acquisition applications. Single- and dual-channel cards are offered. The devices are conformance tested to ODVA standards (volume 3, v. 1.8 for DeviceNet). The DN4 DeviceNet USB module provides a DeviceNet interface for PC communication used in control and monitoring applications. The cards support bit-rates of 125 kbit/s, 250 kbit/s or 500 kbit/s. Applications include PC control, I/O emulation, HMI/Scada control systems, PLC programming, network configuration, diagnostics and troubleshooting for industrial networked equipment including programmable controllers, I/O modules, panel PC and process instruments. The modules are used in application areas ranging from manufacturing computer chips, to high-speed robotic controllers for industrial automation in the automotive, aerospace and defense industries.
The company also offers the Brad ApplicomIO CANopen interface cards equipped with one CANopen port handling CANopen NMT master protocol. The SJA 1000 CAN controller and the 82C251 CAN transceiver by NXP are built-in. Bit-rates up to 1 Mbit/s are supported. The CAN interface is accessible via a 9-pin D-sub connector with the pinning compliant to the CiA 303-1 recommendation. Beside CiA 301 (basic CANopen functionality) and CiA 302 (additional CANopen functions) specifications, the devices support such CANopen device profiles as CiA 401 (for I/Os), CiA 402 (for drives and motion controllers), CiA 404 (for measuring devices), and CiA 406 (for encoders). The I/O acquisition cards provide such additional information as device status and diagnostics, process data read/write monitoring, communication tools for troubleshooting, hardware and software Watchdog, etc. The communication layers are embedded on the cards. The configuration software console provides an environment for development of communication applications. It offers automatic device detection, user configuration management, diagnostic information, etc.
Manufacturer's Brad Enetmeter DN diagnostic tool is a passive device that continuously monitors a DeviceNet network and sends the information over Ethernet to a PLC or PC monitoring system. It uses high-speed sampling (up to 100 mega-samples per second) of critical network parameters (CAN signals, power and shield voltage). By comparing acceptable baseline measurements of a known, standard network, it can predict imminent failures down to individual devices and proactively respond to out-of-tolerance parameters. The portable test unit with IP20-rated housing can be DIN-rail or direct-panel mounted. The Netalytix software offers real-time display of power and provided CAN signals. It is also able to save a network baseline report (.csv format) for later comparison. As all network warnings and faults are summarized in a window, users get a clear picture of current network issues for immediate resolution.
Molex also provides diverse digital I/O modules for CANopen and DeviceNet featuring different numbers of inputs and outputs. It delivers interconnect solutions for markets including data communications, telecommunications, consumer electronics, industrial, automotive, medical, military and lighting. Established in 1938, the company operates 40 manufacturing locations in 16 countries.
