From Extreme Skepticism to Wireless I/O

Dear Friend Subscriber: It s almost impossible to believe that just 10 years ago a lot of people thought industrial networks were risky, unreliable and extravagant. Now people are doing I/O over wireless Ethernet. Let s not forget that back then installing a modem in your Windows 95 computer often required eleven attempts at jumper switch configurations, device driver re-installs and machine reboots. Compared to all that, 75 feet of wire running from PLC to prox switch was a lot easier and a lot less expensive. microsoft

Still, I say: If Jane Q. Public can get her SMTP right and send emails to her tea-tasting friends, then wireless is surely practical too. Even in a world where your electricians distrust anything their voltmeter can t understand. laptop computers

So we re full steam ahead with a whole suite of wireless solutions. Wires are a big pain in the butt anyway. I m happy to report they re mostly unnecessary. If you re gonna replace wires with air, I ve got some things you ll want to know. laptop computer

First, there s always a series of tradeoffs - between speed, redundancy, power consumption, complexity, distance. On this page you ll find a chart that helps you quickly determine which networks fit your requirements: desktop computer

You see here that Wireless USB and Bluetooth are great for short distance, high speed communication but would never work for a long distance app at a wastewater treatment plant. And there are very few industrial USB / Bluetooth products. 802.11 is the reliable standby these days. But if you re doing simple I/O it s got a lot of overhead and isn t going to be nearly as fast as it sounds. Not to mention, 802.11 will catch the interest of your IT department, I ll let you be the judge of whether that s good or bad notebooks

ZigBee (more correctly, 802.15.4, but that s not nearly as fun to say) is great for sending short packets of data at low speed, but you wouldn t use it to transmit video. If you re using ZigBee here s what our Zlinx approach looks like: lenovo

http://www.bb-elec.com/ .asp MultiFamilyId=67

1. First, you decide whether you re doing simple Wire Replacement, or Modbus data communication between sensor and controller. 2. You choose a wireless base module. Based on your distance and I/O needs, you pick. Transmission range is 300 feet to 14 miles (20km). Hang our Wireless Base Module on a DIN rail next to your PLC. 3. You pick the wireless I/O modules you want. Various combinations of 2, 4 or 8 inputs / outputs available. Analog / digital. Snap them together with the base module. hard drive

4. If you re using a Modbus system, choose a Radio Modem. There s a table that tells you which base module works with which radio modem. Communicates to your PLC or HMI via Modbus protocol. Connects to Wonderware, Labview or any other Modbus compatible software. Or, if you re just doing wire replacement (like remote sensors into PLC inputs), buy a pair of systems and set them to peer-to-peer mode. travelstar

Deep Throat, Flower Pots and Mighty Deeds of Valor

Dearest Friend Subscriber, hard drives

Ol Deep Throat finally came forward with his real identity. electronics

Dang, I was hoping for... well, someone more mysterious and intriguing than a 91 year old grandpa. Perhaps a vast conspiracy from the Trilateral Commission or a deep dark plot from the mind of Jimmy Hoffa. You know, something worthy of a Watergate scandal. canon

But after reading about Deep Throat and his clandestine meetings with the young reporter Mr. Woodward, I did get some new ideas that we re going to implement right away here at B B. This is gonna keep competitors from finding out about our new products. desktop pc

Me and my engineers are going to start giving each other secret signals involving a flower pot and a red flag. desktop computers

And if there s a message I need to get to Mario, email is strictly forbidden. From now on, I circle page 20 of his copy of the New York Times, delivered to his apartment, and draw the hands of a clock indicating the time we re to meet that night. The first meeting will be at 2am in barn outside Ottawa, Illinois. think pad

Speaking of clandestine meetings and secret signals, let s talk about System Integrators for a minute. repair

Got a call on a Thursday afternoon from one in Montana. Needed some RS-485 USB isolated converters pronto, was wondering if we could drive some of these over to Milwaukee for a Substation job that had to be finished by Friday. Plus, this was just before Memorial Day weekend. data recovery

I said, Take this job and shove it, pal. cisco

OK, so I didn t say that. I actually called my competitors local distributors (the ones we keep in the dark with those flower pots, flags and 2am product planning meetings in a barn). keyboard

Naturally the competitors distributors had nothing in stock - not even anything similar. monitor

Zip. Zero. Nada. desktop

But the heroic person inside of me - the one that admires a #2 FBI guy for blowing the whistle on El Presidente - that heroic part of me rose up with a mighty shout. Man, if I had to carve those USB converters out of a bar of soap, so help me I was gonna help this guy. I marshaled my forces late that Thursday afternoon to produce the desperately needed, life-saving parts he needed. We shipped them overnight and the man s bacon and certainly his weekend) was saved. infosys

The moral of the story is, while our competitors distributors are out having barbeques and bar mitzvahs, we toil through the long dark night of a System Integrator s soul, ceaselessly delivering the goods so that You, our Customer, can be the hero.

- Electrically Erasable Programmable Read Only Memory - memory that retains data even when the power is off. EISA - Extended Industry Standard Architecture. A 32-bit PC expansion bus designed as a superset of the ISA bus. Designed to expand the speed and data width of the legacy expansion bus while still supporting older ISA cards. ISA bus cards can plug into EISA slots. mainframe

EMI/RFI

- Electro Magnetic Interference/Radio Frequency Interference: signals generated by expanding/collapsing magnetic fields such as motors, transformers, arc welding, fluorescent/neon lighting, radio/television Transmitters, motor brushes, lightning. EMI/RFI Immunity - The level at which a device or signal is unaffected by EMI/RFI Enhanced Address Decoding - samsung

Decoding of the full 16-bits of the ISA bus address and the full 32-bits of the PCI bus address. Some interface cards don t decode the full address. This means that such a card will respond to commands at more than one address, so that conflicts with other cards are more likely. Decoding the full address prevents a card from causing conflicts. computer repair

Enhanced Timer Mode

- A timer feature used to prevent slave devices from receiving preamble commands, inadvertent switching from binary/graphic file transfers, and inactive slave devices from holding control of the master port. The switch can monitor the data line, if there is not any activity for a specific time it will disconnect from the master. Alternately, the switch can ignore commands for a specific amount of time. used computers

EPP

- Enhanced Printer Port - a printer port that has additional registers and generates the handshaking signals in hardware. Compared to a standard printer port which requires several port writes and reads for each byte transferred, once a EPP port is set to EPP mode, only one write is needed for each byte. EPP software is required to use the EPP port in EPP mode, otherwise it functions as a SPP (Standard Printer Port) or BPP (Bi-directional Printer Port). network

Ethernet

- A type of LAN invented by the Xerox Corporation and developed in cooperation with DEC and Intel. The original Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Originally Ethernet was specified to transfer data over thick coaxial cable at a speed of 10 Mbps. Now the term Ethernet typically encompasses all of the versions of the IEEE standard, which has adapted to include higher data rates and different media, including thin coaxial, twisted-pair, and fiber optic systems. digital cameras

The most common types of Ethernet in use today are 10BaseT, which uses twisted pair cable at 10 Mbps, 100BaseT (or Fast Ethernet), which uses twisted pair cable at 100 Mbps, and 1000BaseT (or Gigabit Ethernet) which uses twisted pair cable at 1 Gbps. Fiber optic cable is also a popular medium for each of the connection speeds. desktops

Ethernet Port Server

- A device that connects to the LAN with Ethernet connections. It may provide serial services to the network, printer services, CD-ROM services, Facsimile or other services. Externally Powered - cognos

1. Requires connection of a power source such as AC or DC. The required power source is rated for the type of voltage in volts (VAC or VDC), and the required current in mA (milli-Amps), A (Amps) or VA (Volt-Amps)/Watts. hosting

2. A externally powered converter which doesn t support Port Power must obtain power though connection terminals, a DC Jack or Connector pins. Isolated converters may require port power for the RS-232 side, a power supply for the RS-422/485 side. netfinity

Fallback Switch

- A switch that normally selects a primary data path for serial connections, the selects a secondary data path if the primary data path is lost. The B B fallback switch supports this mode, or can select the primary data path until the alternate data path is activated, it then selects the alternate path until the alternate device is finished, then the primary data path is reselected. The B B fallback switch can also be used as a port combiner that selects the primary or alternate when data is ready for transfer, locks out the other path until transfer is completed. internet

Fax Class 1 Commands

- A standard set of Facsimile (FAX) machine commands supported by some FAX/Modems. Fax Class 2 Commands - An extended set of Facsimile (FAX) machine commands supported by some FAX/Modems. Female (Connector) - Connector which has a receptacle socket (holes) for pins. When F follows the connector type, the connector is a female connector. cheap computer

Fiber Optic

- Light transmission through flexible transmissive fibers for communications, imaging, or lighting. Offers significant distance, bandwidth, isolation, and EMI/RFI immunity over traditional copper installations. Fiber Optic Converters - A signal converter with fiber optic transmitter and fiber optic receiver for the optical signals and electrical inputs outputs for another signal format such as RS-232, RS-422 or 2-wire or 4-wire RS-485. digital camera

FIFO (buffer)

- First In, First Out - FIFO implies a queue and buffer to hold it. The oldest data item in the buffer is the first item retrieved. Contrast with LIFO (Last In, First Out) which operates like a data stack, items placed on the stack are retrieved first in the order of last first. Full Duplex - A full duplex communications system is able to transmit and receive at the same time. Two communications paths are provided, one for each direction. Examples are RS-232, RS-422 and 4-wire RS-485. (2-wire RS-485 is half duplex) printer

Gender Reverser

- A connector with dual male or dual female connectors wired pin for pin. Used to change or connect two female devices together (using dual male) or two male devices together (using dual female). GHz - Giga Hertz (Hz x 10 to the 9th power) - 1 GHz=1000 MHz GPS - Global Positioning System - A device which uses 3 or more of at least 24 satellites in orbit to determine the local position on earth of the receiver. 3 satellites are needed for a 2D fix, 4 for a 3D fix which includes altitude. Accuracy of position can vary depending on the location of the satellites used, altitude accuracy for civilian uses can vary by +/- 500 ft. Two frequencies are used, L1 (1575.42MHz) for civilian, L2 for military. The date and time are broadcast for positioning references to downloaded tables used to calculate the position. GPS receiver outputs are used in marine and land based navigation systems which interface to a computer through RS-232 or RS-422/485 serial connections. xseries

Ground Loops

- When two or more devices are connected to a common ground through different paths, a ground loop occurs. Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment. To prevent ground loops, all signal grounds need to go to one common point and when two grounding points cannot be avoided, one side must isolate the signal and grounds from the other. maxtor

Grounding Strap

- data storage

1. A heavy solid or braided wire cable used to provide a low resistance path from a device to a earth ground. Used with surge suppressors. hitachi

2. A conductive wrist strap and grounding cord used to discharge static voltages to ground when handling ESD (Electro Static Discharge) sensitive devices such as interface cards. rational
