When working with industrial networks, one of the biggest challenges is finding a way to enable communication between devices that use different interfaces and protocols. Moxa products are being used to connect and control industrial devices over different media. Read the case studies to learn more about how Moxa products are implemented in different industrial sectors like Transportation, Power and Utilities, Medical and Healthcare, Monitoring and Control Systems, Process Automation and so on. Moxa products are designed to establish network connections for devices that use the following interfaces and protocols:

Moxa products are specially designed to connect industrial device over media such as RS-485, cellular networks, Industrial Ethernet (Industrial Ethernet Switches, IEC 61850-3 Ethernet Switches, EN50155 Ethernet Switches, Ethernet Media Converters), Industrial Wireless (Industrial Wireless LAN, Industrial Cellular, WLAN Antennas, Cellular Antennas, Wireless Accessories), Industrial Computing (Embedded Computers, Wireless Embedded Computers, Wide Temperature Computers), Remote I/O (Cellular GPRS I/O, Active Ethernet I/O, Remote Ethernet I/O, Modular I/O, RS-485 I/O for RISC Linux and ucLinux) Serial and USB Connectivity with products that offer communication solutions for almost any application involving industrial devices with serial interfaces, including RTUs, PLCs, IEDs, sensors, device consoles, e.g.:

Or with Embedded Networking which are designed for manufacturers who want to add sophisticated network connectivity to their serial devices like these;

• Serial-to-Ethernet Modules. Serial-to-Ethernet device servers are specifically designed to be small, consume less power, and easy to integrate. Moxa’s embedded device servers support TCP server, TCP client, UDP, and RealCOM operating modes so that transmitting from serial devices to Ethernet is easy and effortless;
• Serial-to-WiFi Modules. Embedded wireless device servers that provide serial devices a wireless connection to a wireless Ethernet network. Moxa’s embedded wireless device servers connect your serial devices to an 802.11 a/b/g network;
• Embedded Ethernet Switches. Moxa’s embedded managed Ethernet switch modules are designed for device manufacturers to embed a small sized switch module in existing devices to enhance performance and redundant network capabilities. With smart management features, low power consumption, and extended operating temperatures, Moxa embedded switch modules offer a reliable solution for your mission-critical embedded applications.

Moxa offers industrial-grade serial communication solutions for PCI Express or PCIe boards. The advanced UART (universal asynchronous receiver/transmitter) chip ensures high throughput for serial data. In addition, advanced communication functions are available to provide a high degree of control. Numerous drivers for GNU/Linux operating system are included in the Products section. NOTE: support for MOXA Intellio family multiport serial driver boards are actively developed in the Linux kernel (since version 2.2.14). This driver are on the path linux-<version 2.6.xx.yy>/drivers/ added to the char/ directory in the files moxa.c(h) and mxser.c(h).

PCAN-Light drivers gives you access to all the CAN adapters under GNU/Linux manufactured by PEAK-System Technik. The PCAN-Light drivers for GNU/Linux need a Kernel Version 2.4 or higher. The complete package is freeware and is distributed under the GNU GPL license. The API (Application Programming Interface) for all the adapters is the same, so it is easy to develop software that runs with all the different CAN adapters Interfaces. At the moment it supports the PCI (image in this article), Parallel, USB, PC/ISA and PC/104 adapters; a complete list here. PCAN-Light consists of the actual driver. You can use the PCAN-Light API to create your own applications for communicating with the PCAN-PC hardware. The GNU/Linux version of the device driver is obtainable as source code for PCAN-Dongle, PCAN-PCI, PCAN-PC/104 and PCAN-ISA. Libs are available for the PCAN-USB hardware.

This project is to control Velleman PCGU1000 function generator with USB port. For communications trough USB, libusb unit is used. Directory of program, which uses this project, must contain file pcgu1000.bit (microcode for generator). This file can be also downloaded from Velleman's site. Currently it can control all parameters of generator like: on/off, -40dB, attenuator, offset, amplitude fine tune, filter, freq, sweep, waveform and so on. Standard signal waves like, e.g., sine, triangle and rectangle are available; other sine waves can be easily created. The signal waves are created in the PC and produced by the function generator via DDS (Direct Digital wave Synthesis). All outputs are galvanically separated from the PC in order to avoid measuring problems. Some features and specifications are:

• Frequency range: from 0.01Hz to 2MHz;
• Crystal-based stability;
• Low sine wave distortion;
• Two parallel output connectors for waveforms;
• TTL-level synchronization output;
• Standard waveforms: sine, square and triangle;
• Predefined library waveforms included: noise, sweep, ...;
• Amplitude range: 100mVpp to 10Vpp @ 1kHz// 600 Ohm load / 0V offset;
• Frequency setting resolution: 0.01%;
• With internal 40 dB attenuator (output divided by 100);
• Direct digital wave synthesis (DDS), stores up to 8192 of waveform points;
• Amplitude resolution: 0.4% of full scale;
• Offset: from 0 to -5V or +5V max. (resolution 0.4% of full scale);
• Vertical resolution: 8 bits (0.4% of full scale);
• Sample rate: 50MHz;
• Typical sine wave distortion (THD): < 0.08%;
• Output impedance: 2 x 50 Ohm.

This project, realized on freepascal with Lazarus, is a free software under the GNU GPL license and can thus be used and modified freely. For any further information click here.
