Come see AutomationDirect at National Manufacturing Week in Chicago
AutomationDirect is 10 years old this year, and we'd like you to come help us celebrate! We're having a party at National Manufacturing Week, Feb. 23-26, 2004, at McCormick Place in Chicago, Illinois, to thank everyone who helped us achieve this milestone. We invite you to drop by Booth 5611 and meet some of our team members, including company president Tim Hohmann, who have worked to give you outstanding service through the years. Join us for technical demonstrations, and see displays and literature for new products, including Fuji Electric motor controls, Marathon MicroMax motors, relays, signal conditioners and more. We'll also be presenting product overviews in our seminar area throughout the week. And the best part - free food! Stop at the Hospitality Desk for A.M. wake-up coffee and brownies, and P.M. popcorn and a refreshing glass of water. Remember, Booth 5611 - see you there!
Schedule for Interconnecting Automation Training classes
Interconnecting Automation, an AutomationDirect federation partner, delivers training to customers using AutomationDirect products. Classes for PLC-based systems are held around the country and are delivered by Doug Bell, who has over 20 years experience in the industry. Following is the schedule for training classes for the first half of 2004:
March 2-4 Atlanta, GA
April 6-8 Irvine, CA
May 4-6 Charlotte, NC
June 22-24 Orlando, FL
February 10-12 Dallas, TX
March 23-25 Milwaukee, WI
May 11-13 Atlanta, GA
June 1-3 Irvine, CA
InterConnecting Automation is also now offering a PID class. Doug Bell will team up with Cecil Smith, a 30 years+ expert in PID function. The class is two days and is strictly devoted to PID function. You'll get experience with state-of-the-art equipment and have the benefit of two instructors at your disposal.
The PID class will educate you on the short cuts and tools that the experts know and use. You will learn to setup, tune, troubleshoot and debug PID loops. You'll also get experience adjusting the gain, reset, rate, and many other PID parameters, to see how they affect the loop.
Interconnecting Automation will offer this class only twice this year (May 18-19 and a December date yet to be determined) and it will be held at AutomationDirect headquarters in Atlanta, GA. If you are interested in attending, visit http://my.execpc.com/~icauto/ and email your name, address, and phone number. InterConnecting Automation will then contact you with information on this specialty class.

Equipment lease financing option
AutomationDirect has partnered with Premier Funding Group, Inc., a national equipment leasing company, to provide a lease financing option for purchases over $3,000. This program allows you to spread out payments for your order into convenient monthly installments ranging between 24 - 60 months. This can help you get critical equipment for your business without depleting capital that may be needed for other purposes. Because of the fixed rate, leasing can also help stabilize cash flow and budgeting for your business operations. Credit approvals are typically processed within 4 hours and final lease agreements within 24 hours. If you have any questions about the program, feel free to contact the Premier Funding Group via email at firstname.lastname@example.org or via phone at (866) 244-6483. If you are interested in pursuing a lease on an upcoming purchase, you can begin the process by speaking with one of our customer service personnel at (800) 633-0405, or while shopping in our online store, look for "Lease Financing" as one of the payment options during the checkout process.
If you have ideas or suggestions on how we can make our Web site serve your needs better, we want to hear them. Please

Filtering of Noisy Process Variables
by Luis Miranda, ADC Tech Support team member
The problem of noisy signals in the measurement of process variables can typically be solved with careful design, taking into account components, layout, wiring, grounding, shielding, etc. However, no matter which layout you select, electrical noise may still be present in the input signal of a PLC.
In the most severe cases, it is necessary to resort to signal filtering, either by hardware or software, to smooth the reading. The value of the process variable can also be unstable due to the quality of the measuring instrument. For example, in the cement industry, the signal output generated by impact flowmeters of granulated or dusty raw materials results in a value that must be averaged. Even the value of the gasoline level in an automobile tank needs to have an algorithm that calculates the average of several readings, to prevent the needle of the indicator from jumping when the automobile moves.
Running average is one of the methods used to smooth readings of analog values. In this algorithm, the parameters are the number of samples and the sampling period of the signal. This method consists of taking a consecutive number of readings, not necessarily at the same frequency of the CPU scan, and placing them in a table. In each sampling, the new value is placed at the top of the table, all the other values will move downwards, and the oldest value is lost. At the same time, all the values of the table are added and the arithmetic average of those values becomes the running average. Then, in each reading, there is a value that is the average of all the samples. If it is known that the process variable varies slowly, as is the case with temperatures or water level in a tank, this method can be easily applied.
A solution for AutomationDirect's DirectLOGIC PLCs is as follows:
In this example diagram (diagram will open in a web browser window), assume that there is a range of temperature with a noise signal that can cause the value of the signal to jump instantaneously, which can then cause a non-acceptable deviation or enough change to activate an alarm. We want to smooth the reading of a 12 bit analogic signal read by a PLC with a scan time of 9 milliseconds, (i.e., on each 9 msec there is an update of the reading). In the example, we will take a value each 11 CPU scans.
The table to use is V10000, with 10 consecutive registers, or a table of a length 10 (V10000 until V10011). The signal value to be averaged is V4000. The result is obtained in V5000 as a BCD value.
Next you can see an implementation of the algorithm with a period of sampling of 100 milliseconds and 10 samples. This can be extended to more samples, and the period can be changed within the possibilities of the CPU. Furthermore, the averaging and sampling in each CPU scan can be done by slightly modifying the program.

Application of the month: DL205 and EZTouch increases productivity for coil form manufacturer
Products used: DL205 and 6" EZTouch
Description: Cosmo Corporation produces coil forms for the electrical and electronic industries. This includes thermoplastic and thermoset molding as well as round wire, square wire, flat terminals, and assemblies. My challenge was to improve the assembly operations. By implementing systems using the DL205 and EZTouch panels, I was able to build user-friendly controls which include automatic and manual operation, but more importantly, complete diagnostics and data collection at the touch of a button. The new controls and diagnostics reduced maintenance requirements to the barest minimum, and the data collection provides production with accurate, real-time operator, part number, and machine capability information. This being a newly implemented project, the full impact of the improvements is yet to be appreciated, however I can say that the reduction in maintenance, increased reliability, and improved performance has improved productivity by nearly 14%, and the production data provides information for accurate/competitive pricing of our products.
