Today's monitoring and data acquisition systems need to acquire information, such as temperature, humidity, door open/closed, and other I/O events, from local and remote sites to improve enterprise productivity. For large scale and remote applications, systems have become more distributed and rely heavily on Ethernet and IP-based networks. The way remote I/O is implemented is a key factor that determines the efficiency of the monitoring system.

Two types of Ethernet I/O are currently available. Traditional PC-based Ethernet I/O, or passive remote I/O, is built on passive I/O devices that require instruction from a PC for operation. Active Ethernet I/O is based on self-directed operation of I/O devices, for automated status reporting and simple local control.

Passive Ethernet I/O
In passive Ethernet I/O systems, a host computer obtains data from I/O devices by continually scanning each device. For local area network environments, obtaining instant, or real-time, I/O status is possible only when devices are scanned very frequently. However, frequent scanning over the network results in high network overhead.

When I/O points are distributed throughout remote locations, response times cannot be guaranteed. This is a challenging situation for programmers if the timing of devices and readings is important to the application. Typically, timely I/O data measurement in this situation requires the installation of a separate host computer with physical proximity to the I/O devices. The on-site computer then forwards the data to a central host computer for actual processing.

Active Ethernet I/O
In an Active Ethernet I/O system, a host computer does not obtain data by scanning each I/O device. Instead, the Active Ethernet I/O server proactively transmits I/O data under user-specified conditions that are defined through simple logic configuration. No programming is required, network usage is greatly reduced, and I/O data is obtained by simply waiting for automatic reports from the I/O server. Multiple transmission protocols are supported, such as TCP/UDP, SNMP trap, SMTP (e-mail), and Modbus/TCP.

Comparison of Functions
The following table summarizes the main differences between the two available options for Ethernet I/O.

Present and future investment:
Active Ethernet I/O maintains support for the Modbus/TCP protocol while also enabling a new proactive method to obtain I/O data in a PC-based data acquisition & control system.

Faster project implementation:
MOXA's Click&Go logic configuration engine for Active Ethernet I/O provides an easy, intuitive interface for even first-time users to define the control logic and message content, without programming.

Additional information:
MOXA has launched a theme site that introduces the exciting new Active Ethernet I/O concept. The theme site is located at: http://www.moxa.com/Zones/Active_Ethernet_IO/index.htm. The site includes a special section with a detailed introduction of the Click&Go logic control interface, which is the core engine of Active Ethernet I/O. Additionally, three success stories are presented where Active Ethernet I/O is already being used for industrial and commercial applications.

Click&Go logic control is a patent-pending technology developed by MOXA. It unlocks the power of Active Ethernet I/O with an intuitive, instantly understandable interface. Click&Go is so easy to use that a beginner can complete Active Ethernet I/O configuration in just a few steps.

With Click&Go, users have full control over when to send I/O data, what information to send, and where information should be sent. It allows easy customization of I/O messages using dynamic fields such as time and date stamp. Multiple input signals can be integrated into a single event that triggers an I/O message and local output signals. After defining a set of rules with Click&Go, your ioLogik E2000 I/O server will be able operate independently of a PC, proactively transmit I/O information, and provide automated control of local output signals. Not only does your I/O server become smarter, it also becomes faster, resulting in dramatic reductions in response time (50 ms as opposed to 1 sec) and network loads. All this is accomplished without any programming or specialized training due to Click&Go's intuitive interface.

Whereas other control solutions rely on programmers to develop specialized C-language applications or PLC ladder logic, Click&Go can be instantly used by anyone who understands basic If-Then statements. With Click&Go, Active Ethernet I/O can be fully configured on your ioLogik E2000 server in just four easy steps:

Step 1: Run ioAdmin to access Click&Go
Step 2: Use If-Then statements to define rules
Step 3: Download logic to server
Step 4: Run ioAdmin to activate Active Remote I/O operation

Traditional remote I/O solutions rely on PC controllers or hosts for operation, especially when instant access to remote sensors and switches is required. This can generate up to USD$1500 in extra costs for hardware, operating system, and SCADA software (costs may differ between different regions).

Active Ethernet I/O does not require a separate PC controller, additional software, or programming for operation. It is designed to provide all the functionality of traditional remote I/O systems in one package, while also providing peer-to-peer communication over Ethernet, local output control, and automated I/O event reporting. Since a separate PC controller is not required, there are no costs associated with operating systems, proprietary SCADA software, or additional wiring. Also, Active Ethernet I/O is designed for easy setup by beginners, saving both time and money spent on specialized programming. These savings can accumulate to a dramatic 80% reduction in total system costs, compared to a similarly equipped traditional remote I/O system.

Due to the rough geography and long, winding roads, it has been both challenging and expensive to maintain a clean municipal water supply for the villages in a certain mountainous area. For maximum efficiency, large water reservoirs and towers were used to keep the supply stable and allow storage and exchange. However, the PLCs that monitor and control the water equipment use RS-485 for communication, and the maximum transmission range was not long enough to allow communication between villages.

A typical solution in this situation would be to use media converters and fiber-optic cables to extend transmission of the serial signals. For multi-drop RS-485 networks, PLC nodes would be connected to each other in a chain using segments of fiber optic cable capped with serial-to-fiber converters at both ends. Each node would therefore require two converters—one for the node before it in the chain, and one for the node after it. Between each node would be a pair of fiber cables—one cable for transmission, and one cable for reception.

MOXA offers a simpler and more cost-effective approach using TCF-142 converters arranged in a ring. In the MOXA solution, each PLC node requires only one converter, and connections between neighboring PLCs require only one fiber optic cable. This resulted in an immediate and dramatic savings in the cost of materials. The ring was arranged so that data traveled in one direction around the ring, with each node transmitting data to the next node and receiving data from the previous node. Installation was much simpler since configuration was not required. In addition, since the TCF-142-S V3.1 can transmit over a distance of 40 km, as opposed to the 20 km supported by other converters, it was perfect product for the long distances between water towers.

Advantages of MOXA TCF-142 converters:

• Both "Ring" and "Point to Point" transmission
• Up to 40 km extension of RS-232/422/485 signals (TCF-142-S V3.1)
• Up to 921.6 Kbps baudrate
• 12 to 48 VDC input
• Wide temperature range: -40 to 75°C
• Small size

PLCs are a common solution in many industrial fields. Their programmable operation and ability to connect many devices are particularly useful in establishing industrial automation systems. However, there are several disadvantages that are often encountered when using traditional PLC solutions:

• It is not always possible to obtain real-time data from attached devices.
• Programming for PLCs is complicated and can require significant time, manpower, and expense.
• Protocol converters may be required to attach devices that do not support RS-485 transmission.

Since MOXA's UC-7410 embedded computer addresses each of these disadvantages, it has been used to replace PLCs in a power substation in China. The UC-7410's programmable platform allows it to be used as a helpful protocol converter for effortless communication between different devices. Real-time data collection is achieved by connecting each device directly to the UC-7410. RS-232/422/485 operation is selected by software, making additional interface conversion unnecessary. The UC-7410's powerful combination of features makes it an ideal solution for PLC-related applications.

UC-7410 provides the following benefits:

• Active queries to attached devices can be used for real-time data collection and processing.
• Devices can be immediately connected without using an interface converter, due to serial ports with software-selectable RS-232/422/485 operation.
• The embedded Helios software can be used to establish a centralized management architecture.

Roadside cabinets contain equipment that serves the households in a particular area. Many different devices, such as traffic devices or telecom equipment, can be installed in the cabinets. Traditionally, roadside cabinets were used primarily to serve rural and remote areas, but they are now common in urban areas as well. Whether driving on the highway or walking on the sidewalk, roadside cabinets can be found almost anywhere.

Traditionally, remote I/O servers or PLCs were installed to monitor the equipment housed in a roadside cabinet. However, for Ethernet-based monitoring with PLCs, this meant that it was necessary to purchase expensive Ethernet modules for the PLC separately. Another significant obstacle was the challenge of developing custom software in order to monitor all I/O channels.

These problems can now be solved using MOXA's Active Ethernet I/O, which is a new concept of Ethernet I/O architecture. With Active Ethernet I/O, MOXA introduces the killer feature of automatic I/O status reporting, eliminating the need to poll for I/O data. The intuitive Click&Go interface is used to configure the control logic and can also provide simple local control.

Why MOXA?

• Active I/O messaging for remote monitoring
• Local control with Click&Go logic
• Support for various I/O types
• Easy-to-use MXIO library

MOXA's NPort 6000 device servers have been selected to help automate operations at China's first unmanned iron ore loading facility.

A major component of the facility's operation involves iron ore pellets that travel in piles on two large conveyors for automated handling. Scanner-equipped loading arms automatically generate 3D computer models of each pile to determine how each pile will be processed and loaded. The large volume of information means that conventional data transmission speeds are not sufficient for automated processing. The scanners, produced by leading manufacturer SICK, are set at 38.4 Kbps and must switch to 500 Kbps, which is a nonstandard baudrate.

MOXA's NPort 6000 device servers were selected for their ability to connect SICK scanners instantly to the Ethernet network, which is something no other device server was able to accomplish. Effortless support for nonstandard baudrates, including the 500 Kbps used by the SICK scanner, was a key advantage. Moreover, the NPort server's industrial-grade design ensured a reliable and secure data transmission tunnel to prevent loss or interception of data.

Unmanned loading is an important development for the steel industry, which is characterized by hazardous workplace environments where serious injuries can occur. The move towards increased automation is expected to result in safer working conditions, higher efficiency, and substantial financial benefits.
