The Future of Industrial Networking

Tuesday, December 13th, 2011

What is an industrial network driven on?   What will prepare a network for the future?  Microprocessors are the “Heart of the Network,” according to Jim Montague, executive editor at Putman Media.  “Heart of the Network,” featuring our own Mike Justice, is the featured publication in the fourth quarter 2011 edition of Industrial Networking.

Mike Justice stated, “Microprocessors might be on the lowest layer of the network, but they have a huge influence.”  Chips have evolved from simple standard microprocessors, to application-specific integrated circuits, field-programmable gate arrays, and so on.  Design flexibility is what allows industrial networking to move into the future.

gridARM System on a Chip

Gigabit Ethernet will help industrial networks keep up with the bandwidth requirements for increased network traffic.  Many gigabit products have already hit the commercial network.  It will not be long before the industrial Ethernet networks will need to speed up.  With our new gridARM microprocessor, we are able to supply our customers with a cheap Gigabit Ethernet solution for adding fast Ethernet to their devices.

The gridARM microprocessor is designed for low cost products that require a fast Ethernet connection.  This system on a chip is most flexible because it includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.

To understand why the microprocessor is the underlying technology driving advances in industrial networks and to understand how you can benefit from the evolution of microprocessors, download the full “Heart of the Network” article below.

10 Factors when deciding between Industrial and Consumer Networking Devices

Thursday, October 20th, 2011


1.  Protection against solid foreign objects

What solid foreign objects are a part of your operational atmosphere?  Will your device need to be dust tight, protected against wires, or not protected at all?  If maintenance is not an option due to distance or inaccessibility, then you might need to consider what objects can find their way into your devices enclosure.

2.  Protection against water

This is very important in an outdoor application.  You want your device to be able to withstand rain.  Also what if you need your device to be submerged in water, or need to be able to hose down the device when cleaning an industrial area?  These are all conditions that need to be considered when determining which device to go with.

3.  Protection against oil, coolant, and corrosive agents

Hazardous materials can limit the range of products applicable for use.  Without a doubt, you need to have an industrial product for protection against oil, coolant, and other corrosive agents that might be in that operational atmosphere.

4.  Temperature range

There are typically two temperature ranges to consider in the specifications of a product: operational temperature and storage temperature.  Industrial products tend to have wider ranges for both of these.  If you need to store or use a device in an extreme temperature, you would want to use an industrial device.

5.  Durability

Some applications require a tolerance for impact or fast motion.  Some tests that are done on industrial devices include stationary vibration, shock, and vertical free-fall.  Some devices are also given an impact rating from 0 to 20.0 Joules.

6.  Surge protection

Surge protection ratings specify the protection level electrical devices have from voltage spikes.  In certain conditions components need to be able to withstand large spikes in voltage.  Industrial devices tend to have a higher range of tolerable AC and DC voltage spikes.

7.  Electromagnetic response

In many applications multiple electronics are in the same confined area.  Some of which might have motors, or other components that create EMF.  It is important, in this case, that your device can tolerate different electromagnetic conditions.  Industrial devices have higher electromagnetic resistance than consumer devices.

8.  Power supply

Consumer products are usually powered with a wall plug.  Industrial products are often powered in parallel to each other.  They share power supplies, rather than having a dedicated power supply for each unit.  Some have redundant power inputs that are used with redundant power supplies.

9.  Enclosure mounting

Many consumer devices are designed to be set on a desk or other flat surface and do not include any mounting options.  Industrial products include mounting options such as DIN Rail Mounting and Panel Mounting.

10.  Longevity

Most industrial products in an industrial application would be functional approximately 3 to 5 times longer than a consumer device in normal IT application.

Announcing the gridARM System on a Chip

Thursday, September 22nd, 2011

gridARM System on a ChipToday we are announcing the gridARMtm, System on a Chip, with integrated Gigabit Ethernet. The gridARM is targeted at the low cost embedded marketplace where cost and performance are important. The cost for quantity 100 pieces is $10 each.

The gridARM is designed for low cost products that require a fast Ethernet connection. As most IT networks, PCs and laptops are all gigabit Ethernet, it only makes sense to have all your devices on the network to be as fast as possible. The gridARM is designed to be the main processor in the system. The cost of adding Ethernet to your product is now low and can be a marketing and performance advantage for your product.

The gridARM is available in volume today. The development kit includes an evaluation board, cables, JTAG emulator, power supply and a complete set of development tools including a royalty free real-time operating system, TCP/IP v4/6 library, web server, telnet and example tunneling software.

The gridARM is available in two packages – 225 pin BGA and 208 pin QFP. The gridARM chip includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.

The gridARM is our third ASIC in the family. The LX and EX ASICs have been around since the early 2000 and are used by thousands of customers in commercial and industrial applications. The gridARM is manufactured for Grid Connect by Atmel Corporation.

IP in your hand…Really!!

Monday, November 8th, 2010

The world’s tiniest device server, the NET232jr, was originally nicknamed by its first customer as “IP In Your Hand”.   This clever turn of phrase gave us a few chuckles, but it does point out the amazingly small size of the NET232jr.    The  NET232 “junior” enables serial devices with IP technology in the smallest package available in the world (as far as we know!).

We were able to shrink down the size of our standard NET232 by getting rid of the power regulation circuitry and the power LED.    This change requires that power be provided to the NET232jr over the serial port (coming from the serial device), and that power must be regulated at 3.3VDC or 5VDC.    This obviously means that the NET232jr is not for everyone.

The NET232jr has been primarily used thus far by OEM’s who want to offer it as an add-on for their serial port devices, and who have the ability to modify the serial port of their product to put out the power required.    You might ask “if you’re going to modify your product to put out power on the serial port, why not just go ahead and add the XPort (the main component inside the NET232jr) to your product instead?”    Well, there are several reasons why you might not want to do that.  First and foremost is cost.  Maybe you expect only a limited percentage of your customers to actually need an Ethernet connection.   Why put an XPort in every product?  Why not just sell an add-on that is small, smart, cost-effective and can be customized to your specifications with ease?   This is the motivation for the NET232jr.

Another interesting use of the “junior” is when you have a serial device that must be operational at all times, and you need to “live swap” it for servicing quickly and simply.   If you use the NET232jr as the network connection, then you can leave the NET232jr attached to the network while you swap out whatever serial device is attached.  This means you do not have to reconfigure the network connection for the new device; you simply plug it in and the NET232jr “remembers” the network settings.   Thus, you do not need to call in IT personnel to replace your serial device – anyone can do it – just plug it in!

The NET232jr came into existence when a customer asked for something smaller than the NET232 (which is already one of the smallest Serial to Ethernet device servers on the market).    Grid Connect is happy to discuss your project/product needs with you and see if we can find a solution – even if you don’t see on our website.  We have on staff a team of engineers dedicated to finding solutions to your networking problems.    Maybe you need a custom design that will fit in your enclosure or cabinet.  Who knows – maybe you’ll even see an “IP in your cabinet” blog post someday!

Add One More Serial Adapter and the Universe Might Collapse

Tuesday, August 17th, 2010

A reader over at Gizmodo sent in this picture of a ludicrous chain of serial adapters.

In this chain we have:

  • A Parallel Port DB25 Gender Changer
  • Parallel DB25 to Serial DB9
  • Serial DB9 to Serial Min DIN 8
  • Min Din 8 to USB

The crazier part is that the reader sent in this screen shot and claims that this chain of adapters is fully operational.

It is certainly possible that this screenshot could have been doctored.  We didn’t believe this would work ourselves so we managed to gather up all the right adapters and form our own Serial Adapter Chain.  This one is Busted!  There are a few reasons we believe this would not work, first of all the Parallel Port only puts out 2.5 volts where most USB devices require 5 volts to run.  Also there would have to be some sort of driver used to recognize a USB device on this port.  It appears the person who submitted the picture may have used a strange driver to get it to show up but there is no way they are talking to the USB Flash drive on the end of that chain.

Here is a Picture of Glenn one of our Engineers testing if Power will actually go from a pin on the Parallel adapter all the way through to the USB (it does)

Note: We at Grid Connect do not endorse such an insane chain of serial adapters and typically recommend only using one at a time

Serial Simplified: Serial Communications (1 of 3)

Tuesday, June 1st, 2010

Serial Port

Serial data is still being sent today, one bit at a time, just as it has always been for over 50 years. While serial ports may not be as prevalent on new PCs these days, serial is still in use everywhere. The new PC standard USB has more software overhead and requires more advanced processors to implement, so serial will live on!

RS-232

RS-232 can support data rates of up to 920 kbps (normally 9600 and 115.2K are the maximum rates) and is commonly found in 9 or 25 pin configurations, however only three pins are required. Most applications drop many of the less commonly used pins, though some configurations such as a data modem connect every pin for full handshaking capabilities. An RS-232 is a point to point connection made between a Data Terminal Equipment (DTE) device and a Data Communications Equipment (DCE) device. RS-232 has a maximum cable length of 50 Ft at 9600 baud. This limitation can be overcome by transmitting serial data over another medium.  RS-232 ports/cables can be found in factory automation and metering, medical equipment, consumer products, and many other devices.

Advantages of RS-232:

  • Simple wiring and connectors
  • Widely available
  • Low cost
  • Most embedded processor include this interface
  • Software to implement a serial port is easy

Disadvantages of RS-232:

  • Incompatibilities in wiring and configuration between devices
  • Short cable lengths
  • Subject to noise interference
  • Low data rates
  • Many different software protocols

RS-422

RS-422 offers one of the fastest serial data rates at 10Mbps. RS-422 is a multi-drop configuration, allowing for up to 10 unit loads. Its use of voltage differences makes it ideal for noisy environments. RS-422 can support cable lengths of up to 4000 feet, however its data rate lessens as distance increases.

Advantages of RS-422:

  • High data rates
  • Less subject to noise
  • Longer cable lengths

Disadvantages of RS-422:

  • Not as commonly used
  • Unidirectional
  • For most applications, only one transmitter is used

RS-485

RS-485 provides similar speed advantages as RS-422, allowing for data rates up to 10Mbps. It differs in that it is a multipoint configuration, allowing for support of multiple drivers and multiple receivers. RS-485 can support up to 32 unit loads due to its bi-directional interface.

Advantages of RS-485

  • Low cost
  • Immune to noise
  • Multipoint applications
  • Operates on a single pair of wires

Disadvantages of RS-485

  • Not as commonly used
  • Less standardized connectors and terminology
  • Half-duplex master-slave operation
