AutomationDirect smiley guy reaches new heights
AutomationDirect recently sponsored a long-range rocket that competed in a contest that will appear on the Discovery Channel later this year. Edward Wilk, who works for Facts Engineering, an AutomationDirect partner, is part of a team of rocket enthusiasts who are responsible for designing and building high-powered rockets that are launched in competition. The most recent contest was held in Argonia, KS and was filmed for the Discovery Channel special.
For more information on the rockets and the Discovery Channel special, check out this web site.
The smiley guy can also be seen on our company-sponsored BattleBot, which was the result of a design contest sponsored by Product Design and Development magazine. The BattleBot, named SpinZone, was built by Christian Carlberg, who has built several winning BattleBot designs. SpinZone will be appearing in competition soon. Stay tuned for details on where you can see it compete.

AutomationDirect assists educational institution with PLC training equipment
Fox Valley Technical College in Appleton, Wisconsin, conducted a week-long automation seminar in June for local high school instructors using AutomationDirect's DL05 PLCs. The instructors spent the time learning to use PLCs with sensors and HMI software. They left the seminar with the trainer hardware and software, and will be using their newfound knowledge to integrate automation instruction in their high school curriculums.

Full credit available for switching to ECT promis•e software
AutomationDirect has partnered with ECT International, Inc. to bring you AutoCAD® - based Schematic Software that generates control system schematics, panel layouts, bills of material, wire lists, terminal plans and more, to automate the design process. ECT's promis•e packages offer many benefits when compared to VIADirect UltraLITE software, including ten times the number of parts and five times the number of symbols supported. Prices for the promis•e package start at $995.
VIA Development Corporation, the supplier of VIA Direct software, was recently acquired by AutoDesk, Inc., who will no longer support the VIA Direct UltraLITE software package. Therefore, AutomationDirect is discontinuing the VIA Direct UltraLITE software package and replacing it with the promis•e packages.
To make the switch to ECT's promis•e as easy as possible, full credit for previous purchases of any VIA UltraLITE software package (PC-VIA-ULT), will be offered against the purchase of any ECT promis•e draw and promis•e draw plus version. You must contact AutomationDirect via telephone at 1-800-633-0405 to request this offer.

Networking modules available for DL05 and DL06 PLCs
AutomationDirect has developed advanced networking products for the DL05 nano and DL06 micro lines of PLCs. The D0-DEVNETS DeviceNet Slave Module, priced at $75, transforms any DL05 or DL06 into a smart node on a DeviceNet controller network. The H0-PSCM Slave Communication Module allows any DL05 or DL06 to be networked to any Profibus DP Master. Priced at $259, it offers selectable baud rates from 9.6 K to 12 MB, depending on network length.
New DL06 PLC model available with sourcing DC outputs
A new DL06 CPU with 20 DC in / 16 DC out and a 12/24VDC power supply is now available. The CPU features 14.8K words total (7679 words ladder - flash, 7488 words V-memory), RLL/RLLPLUS programming (DirectSOFT32 Version 4.0 or higher), and two built-in RS232C communication ports.

When to Choose a Temperature Controller Over a Multiple Loop PLC with PID
by Carl Tolbert, Tech Support Drives Specialist
A newsletter subscriber wrote in recently with the following request: "I think it would be helpful for you to provide a discussion of the pros and cons of using separate temperature controller modules versus using a thermocouple module and the PID built into a system."
To answer this question, we must first define a control loop and PID loop. A control loop is a measure of control utilizing the feedback error signal as the controlling medium within a process. The error signal is created between a process variable and the desired set point. Based on this algorithm, the controller will physically change the mechanism that drives the process variable up or down depending on the process needs.
One example of PID in a commonly used application is the cruise control on your car. This is a method of controlling a process around a specific point, with the least amount of fluctuation as possible. An example of what PID is not is a household heating and cooling thermostat system. This is an example of full ON/OFF control (or Hysteresis control), which is less precise than PID control.
The true answer to the subscriber's question rests mainly in application and cost. For example, a PID single loop controller may not be as expensive as one might think, especially when comparing AutomationDirect with other vendors, such as Omega, Honeywell, Watlow, or Eurotherm. A stand-alone, low-cost process control solution can be used for a variety of applications. Here are two examples:
Some other examples of applications that may work well with a single loop controller include applications that require alarm annunciation and display usage via retransmission functions to a larger system, or applications with code requirements similar to NFPA 85 (boiler and combustion systems hazard code) and NFPA 86 (combustion system design). Check out this sample application:
Another good fit for a single loop controller is in the retrofit of older, hard to find controllers. For example, certain models of our PC35 and TC33 have a pulse width modulated output specifically designed to control a solid-state relay. This is one of the oldest and most trusted methods in controlling heater elements and ovens in the world.
On the other side of the coin, PID multiple loop PLCs may be better suited for applications that require versatility. For example, the D2-260 CPU can process up to 16 PID loops directly in the CPU. Various control modes can be selected, including automatic, manual, and cascade control. There are also a wide variety of alarms available, including Process Variable, Rate of Change, and Deviation. The loop operation parameters (Process Variable, Setpoint, Setpoint Limits, etc.) are stored in V-memory, which allows easy access from operator interfaces or Human Machine Interfaces (HMIs). Setup is accomplished with easy-to-use setup menus and monitoring views in the DirectSOFT32 PLC programming software. The auto tuning feature is easy to use and can reduce setup and maintenance time by automatically determining near optimum loop settings.
This solution represents a "medium cost" process control solution that offers the versatility of standalone or multiple loop applications, integrated control functionality and inside and outside control loop data sharing for advanced process control. It also offers data acquisition and trend analysis and the use of DDE/OPC server software to share data to any OPC compliant software package. Additionally, the PLC can communicate directly to a HMI package like LookoutDirect.

Application: Hydraulic punch presses stay running with D2-250 CPU
Products used: DL205 D2-250 CPU, EZText panel
Description: We used a D2-250 CPU and an EZText panel to control the positioning of rotary and slide dies in hydraulic punch presses. Our customer had loss of production from excessive downtime and also had some very costly die repair. We designed and installed a new die monitoring control system and used the EZText panel to allow setup, provide diagnostic messages for faults as they occurred, and to totalize their production. All this will soon be interconnected through Ethernet to an office in order to view production data. The diagnostics have paid for themselves many times over by enabling the operator or maintenance person to get equipment back on line quickly. The customer plans on installing this system into the remainder of their presses. We have made a loyal friend and a very good customer, thanks to ADC and their products.
