1. Control Systems
TURCK introduces BL67 Remote I/O Systems
The BL67 modular concept is a very flexible approach to connectorized I/O; the gateway, base, and electronic module combine many benefits. I/O modules are not dependent on the fieldbus protocol with the BL67 gateway. The gateway provides communication between the fieldbus and the I/O modules. The DIN-rail, or frame mountable base modules, are available with eurofast®, minifast® and picofast® connectors. The electronic modules are hot swappable. The power distribution module (24 VDC) supplies the connected I/O with the required voltage. The system supports multiple networks and a wide variety of I/O signals in a compact and rugged housing. The BL67’s strengths are its openness, flexibility, connectorization and ruggedness.

2. Instrumentation
Paperless recorders offer enhanced functions
The latest additions to the Yokogawa DaqStation family of paperless recorders are the S120 versions of the DX100 and DX200 units, which offer a number of enhanced functions and new capabilities. The DX Series is a family of advanced data-acquisition stations which combine the capabilities of intelligent paperless recorders with powerful communications and networking capabilities. The units feature easy-to-read colour TFT displays: a 5.5-inch display for the DX100 and a 10.4-inch display for the larger DX200.

3. Fieldbus
A Fieldbus Design Tool
Designing a Fieldbus Network can be time-consuming!
That’s why Pepperl+Fuchs developed Segment Checker - a powerful software tool that reduces your design time.
Segment Checker is an open software tool that supports centralized and distributed fieldbus architecture concepts for both FOUNDATION Fieldbus and PROFIBUS PA.

4. OPC Ole for Process Control
OPC Unified Architecture (UA for short) is the next generation of OPC.
First release specification and reference implementation are expected early in 2006.
OPC Foundation has developed UA in recognition of the following factors:
- Microsoft's COM and DCOM, the foundations of earlier OPC specifications, are now officially legacy technologies.
- Web services now offer the primary mechanism for data transport between computers (and also provide a better option for communications with plant-floor devices).
- Earlier OPC specifications failed to provide a single coherent data model - e.g. the Data Access item hierarchy was totally disjoint from that offered by Alarms & Events.
- Backwards compatibility with earlier OPC specifications is key to acceptance of any new standard.

6. Batch S88.01
Batch processing is a common manufacturing method in the chemical, pharmaceutical, pulp and paper, and food and beverage industries. To find out more about the batch concepts used , start by pointing your Web browser to the World Batch Forum's (WBF) Web site at www.wbf.org. The WBF is a nonprofit organization formed to promote understanding of batch process manufacturing concepts, methods, technologies, and standards, and to provide its membership a competitive edge in today's world market. It is an association of end users, vendors, consultants, and academics with a strict, noncommercial agenda. Each year, it hosts a conference with formal presentations and technical papers.
On its Web site, you will find, among other information, abstracts of papers presented at previously held conferences, a more detailed description of the WBF, news about happenings in the batch world, articles by members, and places to discuss batch-related topics with other professionals. You can also find out more about WBF sponsors and order WBF materials online.

7. Industrial Ethernet
Weidmuller Introduces Industrial Ethernet Overvoltage Protection Modules
A serious concern affecting industrial Ethernet networks is the electromagnetic, electrostatic and radio frequency interference generated by machines, power lines and other process control and automation devices that affect Ethernet data cables. These interferences can disturb electrical transmissions, and transients can damage Ethernet devices. Design Best Practices indicate that every active element in an industrial Ethernet network needs to be protected. It is not sufficient to just protect the AC/DC power inputs - the data ports also need protection.
Weidmuller’s Ethernet Overvoltage Protection Modules are designed to be used in between network nodes, and can be connected in series with the Ethernet switches, routers and media converters. Incorporated straight into Ethernet data cables in front of the devices, the OVP modules protect Ethernet ports against voltage and current surges. The OVP module features quick response suppression diodes that respond within a nanosecond of a surge detection to guarantee a high level of protection for signal lines. Surges are safely redirected via a ground connection and the interference voltage is limited to a safe level below 45V. Weidmuller’s Ethernet OVP modules can be used both inside and outside control panel cabinets that do not require an IP67 protection rating. They are available in versions for both DIN-rail and wall mounting.
In addition to Ethernet Overvoltage Protection Modules, Weidmuller also offers managed and unmanaged Ethernet switches, industrial routers, media and protocol converters, electrical cables (patch and network cables), and optical Ethernet cables, cable entry systems, connection modules, cable testers, Ethernet outlets, connection sockets, front plate interfaces, markers, RJ45 dust caps, couplers, plugs, installation flanges, Class 2 approved 24V DC power supplies, and installation and maintenance tools.
