JetNet 5010G is a Managed Industrial Ethernet Switch equipped with 7 10/100TX ports and 3 10/100/1000 RJ-45/100-FX/Gigabit SX/LX combo ports. 2 of the gigabit ports are used to form the nonstop Rapid Super Ring; the 3rd gigabit port is used to connect the upper switch, couple ring or public server. The industrial embedded computer gigabit combo port design allows for flexibility to choose copper or fiber media, 100Base-FX or 1000Base-X, multi-mode or Single mode, for different distances and without stocking different switch models.

JetNet 5010G is designed with a rugged surface in aluminum material, solid design, and a wide operating temperature.

The industrial embedded computer software supports full Layer 2 management features, multi-form ring redundancy, network control, monitor, security and notification.

JetNet 5010G also provides built in watchdog timer, and digital input and relay output to avoid undetected damage.

Blown away by the Industrial Managed POE Switch? Korenix also provides a monitoring architecture which is applicable to many different markets, such as POS, banking, telecom, transportation, industrial automation, energy, power, military, and medical fields. Field site devices such as PLCs, sensors, meters, RFID readers…etc. can be connected to the JetBox 8210 through serial ports, USB ports, and DI/DO. The JetBox 8210 performs as an intelligent agent to monitor the status of field devices and transmit messages to back-end technicians through its dual Industrial Ethernet Switch ports or USB wireless dongle while abnormities occur. Further, the JetBox 8210 with Modbus gateway function let industrial automation developers consolidate field devices into SCADA system easily.

From my understanding i see it as a software identity number that allows various bits of hardware to locate and interact with eachother?

You can configure your system for information exchange between a range of devices

and computing platforms and operating systems.

EtherNet/IP Network

Ethernet Industrial Protocol (EtherNet/IP) is an open industrial networking standard that supports both real-time I/O messaging and message exchange. It is a high speed network and as no established schedule. Ethernet tends to be used as a communication link between the PLC and HMI/SCADA systems.

The Ethernet network can also be used to monitor and program PLC’s on the network using the RSLogix programming products.

ControlNet Network.

The ControlNet network is an open, state-of-the-art control network that meets the demands of real-time, high-throughput applications. The ControlNet network uses the proven Common Industrial Protocol (CIP) to combine the functionality of an I/O network and a peer-to-peer network providing high-speed performance for both functions. The ControlNet network gives you deterministic, repeatable transfers of all mission-critical control data in addition to supporting transfers of non-time-critical data.

ControlNet tends to be used for remote I/O applications and PLC to PLC communications. Due to the fact that ControlNet is deterministic a schedule for the network must be created. The schedule is created with the RSNetWorx software package.

A ControlNet network can also be used in a non scheduled way to monitor and program PLC ’s on the network using the RSLogix 5000 programmer.

Each Ethernet device will require an IP address, and each ControlNet device will require a node number between 0 to 99. A schedule also needs to be created for the ControlNet network this is created with the program RSNetWorx for ControlNet. This is explained in the ControlNet section of the manual

DeviceNet Network.

The DeviceNet network is an open low-level network that provides connections between simple industrial devices (such as sensors and actuators) and higher-level devices (such as PLC controllers and computers). The DeviceNet network uses the proven Common Industrial Protocol (CIP) to provide the control, configure, and data collection capabilities for industrial devices. The DeviceNet network is a flexible network that works with devices from multiple vendors.

DeviceNet is commonly used to communicate to plant I/O devices and variable speed drives.

A configuration file is required by the DeviceNet module this is created and downloaded with the RSNetWorx for DeviceNet software package

Lobel’s Transmitter: sixth generation AST3 weight transmitter is available in a package that weighs less than the mains transformer of the original Scale-O-Scope 25 years ago

In 1973, Bofors Electronic Transmitter(as Nobel Systems was then called), produced the world’s first microprocessor- controlled weight controller and terminal, the Scale-O-Scope.

Over 25 years after this milestone in the history of electronic load cells weighing and force measurement, Nobel’s sixth generation AST3 weight transmitter is available in a package that weighs less than the mains transformer of the original Scale-O-Scope.

The ground-breaking Scale-O-Scope was designed and manufactured by Bofors Electronics in conjunction with its patented KIS dual shear beam load cells for weighing and stock control in the meat processing industry.

The weight controller’s ability to process input and output data, communicate with other Scale-O-Scope terminals, printers and with main frame computers led to a great increase in efficiency, and typically a doubling of profitability in the plants in which they were installed.

The Scale-O-Scope weighed 30kg, used an Intel 4040 4-bit processor with 4k memory, and featured 16-bit A/D conversion, a resolution of 1 in 30,000, and a communication speed of 300 baud.

It boasted digital scaling and set up, keyboard input and a dot matrix digital weighing display with alpha-numeric presentation of weight and data.

The trend since then has seen the extensive use of microprocessor power to give greater flexibility, higher resolution and accuracy, faster speed, easier setting up, smaller size and lower cost.

More than twenty-five years on from the Scale-O-Scope, E-2-TAD weighs in at 3kg, has three microprocessors, a resolution of one in half a million and communicates with RS232, 422 or 423 at 9600 baud .

It is CE EMC compliant, and has OIML (weights and measures) certification for accuracy class III for 10,000 divisions.

Now, the sixth generation AST3 goes one stage better, with an internal resolution of 1 in 8 million (23 bit) using a patented Sigma-Delta A/D conversion technique and communicates on RS485 at 115k baud using modbus protocol.

Analogue outputs of 0-10V, 0-2mA or 4-20mA are standard.

Communication speed is 380 times greater than the original Scale-O-Scope and resolution 260 times greater.

There are no potentiometer adjustments – all scaling is carried out and stored digitally and can be carried out via the front panel keypad or downloaded via the serial port using windows-based software.

Filtering can be pre-programmed to suit the dynamics of the application and is “adaptive” – that is, it has a wide bandwidth and fast response for large weight changes and shuts itself down to a narrow bandwidth for small changes.

The AST3 can also be connected via a modem to allow remote diagnostics and maintenance of the weighing system.

The unit is fully CE compliant to meet the latest EMC and low-voltage directives.

All this comes complete with a digital display in a DIN rail-mounted package that weighs less than 0.5kg.

Small is definitely beautiful – the new AST3 weighs approximately 1/60th of the original Scale-O-Scope of 1973.

This is exemplified by Nobel’s microprocessor-based weighing instruments, the E-2-TAD digital weighing controller and the most recent AST3 weight transmitter.
