SLC 500 System

The Allen-Bradley SLC 500 is a small chassis-based family of programmable controllers, discrete, analog, and specialty I/O, and peripheral devices. The SLC 500 family delivers power and flexibility with a wide range of communication configurations, features, and memory options. The RSLogix 500 ladder logic programming package provides flexible editors, point-and-click I/O configuration, and a powerful database editor, as well as diagnostic and troubleshooting tools to help you save project development time and maximize productivity.

Distributed Systems
More complex systems can utilize: distributed I/O, multiple controllers joined across networks, I/O in multiple platforms that are distributed in many locations and connected over multiple I/O links.
Choose the processor module with the on-board communication ports you need. You optionally add modules to provide additional communication ports for the processor. For I/O in locations remote from the processor, you can choose between a ControlNet, DeviceNet, or Univeral I/O link. A communication interface module is required in both the local and remote chassis.
Depending upon the communication ports available on your particular SLC control system, you can select operator interfaces that are compatible.

Simatic HMI - Series 270

The all-rounder with optimal power and performance
like the series 170 as Touch- or Operator Panels with even more comfort and performance as 6" devices.
Based on the Windows CE operating system, the series 270 panels TP 277/OP 277 offer innovative operator control and monitoring functions combined with the known advantages of Operator and Touch Panels: Ruggedness, stability and simplicity.

ALLEN BRADELY CONTROLLOGIX SLC5000 SERIES

The ControlLogix system provides discrete, drives, motion, process, and safety control together with communication and state-of-the-art I/O in a small, cost-competitive package. The system is modular, so you can design, build, and modify it efficiently - with significant savings in training and engineering.
You can also use the ControlLogix system as a gateway. Include the communication modules you need for connectivity to other networks. For this use, a controller is not required. The ControlLogix gateway integrates into existing PLC-based systems so that users with existing networks can send or receive messages to or from other networks. For a more flexible system, use: multiple controllers in a single chassis. multiple controllers joined across networks. I/O in multiple platforms that is distributed in many locations and connected over multiple I/O links.

Lay out the system by determining the network configuration and the placement of components in each location. Decide at this time whether each location will have its own controller.
Place each controller¡¯s I/O on an isolated network to maximize the performance and to more easily accommodate future network or system configuration changes. If you plan to share I/O, make sure the I/O is on a network that each controller can access.
Assume that Panel A and Panel B both require a controller and its own I/O. Both controllers interact with time critical information. Panel C does not need a controller and can be a gateway.
For a ControlLogix controller to control I/O modules, both the controller and the I/O modules must be directly attached to the same network.
Evaluate what communication needs to occur between controllers. If there is sporadic information that is not time critical, use a message-based network such as an EtherNet/IP (the information portion), Data Highway Plus, or the unscheduled portion of a ControlNet network. If the information is time critical, such as produced/consumed tags between controllers, use a ControlNet or EtherNet/IP network.

SIEMENS S7-400

* The S7-400 is especially suitable for data-intensive tasks in the process industry. High processing speeds and deterministic response times guarantee short machine cycle times on highspeed machines in the manufacturing industry. The highspeed backplane bus of S7-400 ensures efficient linking of central I/O modules.
* The S7-400 is used preferably to coordinate overall plants and to control lower-level communications lines with slave stations; this is guaranteed by the high communication power and the integral interfaces.
* The power of the S7-400 is scalable thanks to a graded range of CPUs; the capacity for I/O is almost unlimited.
* The power reserves of the CPUs enable new functions to be integrated without further hardware investment, e.g. processing of quality data, user-friendly diagnosis, integration into higher-level MES solutions or high-speed communication via bus systems.
* The S7-400 can be structured in a modular way without any slot rules; there is a widely varied range of modules available both for centralized configurations and distributed structures.
* The configuration of the distribuded I/O of the S7-400 can be modified during operation. In addition signal modules can be removed and inserted while live (hot swapping). This makes it very easy to expand the system or replace modules in the event of a fault.
* The storage of the complete project data including symbols and comments on the CPU simplifies service and maintenance calls
* Safety technology and standard automation can be integrated into an S7-400 controller; the plant availability can be increased by the redundant set-up of the S7-400.

AMD Athlon 3500

AMD Athlon 3500+ ($267 shipped); memory is 2 Samsung DIM-DDR400-512 sticks (1 GB total) from Directron ($77.98 shipped). I got this board ($168 shipped) and the processor from BuyXG.com, which had the best all-round price and shipping deal for both, and good ratings. I upgraded from an Asus TUSL2-C, which was about the best board when it was released, and found myself very loyal to Asus following that experience. I did a lot of research before diving in to the A8N-SLI Deluxe. This new board did not disappoint; neither would the non-deluxe version if you don't need the ultimate expandibility the Deluxe brings and you want a heavier wallet. Excellent, easy to read instructions. Form factor is larger that the old board, but it fit fine into my Antec SOHO SX-1035B server case. Processing a particular Quark Xpress file into print-output-quality Adobe Acrobat took 90 seconds. Previously, I could watch almost an entire MASH episode on DVD while the same file processed for 20 minutes on the old system with an 800 MHz PIII and 512 of RAM. I was frankly blown away. No jumpers to fool with unless you want to overclock and the like. The only squinting I had to do was when plugging in the case lights, as the printing is very small, even for someone with good eyesight (but that's a problem with many boards). At this writing, Asus has certified only 3 power supplies for this unit, all of them up there in price. However, I upgraded to a TTGI Super Flower 520 Watt from Directron (about $40) at the same time, and is humming along fine. The PS comes with a 20-pin connector, but the board has a 24-pin. No worries, as 20-pin power supplies work just fine; they can plug in only one way. I can't comment on the SLI performance, I'm using just one 6600GT at this point. If you want to get a board for the future, and that won't be obsolete as quickly as others out there, as SLI and 939 are, this is the board to get. Installation was relatively easy. Windows would not start following the board and chip changeout, but running XP's repair install got it back in shape. Since I had only the original XP disk, I had to run the SP2 installer to get everything working. The only difficulty I did have was getting the built-in networking to work. Running the installer would not work right, so I uninstalled it and did a manual install by pointing to the drivers on the disk. 8 hours from beginning the process to smokin' performance. I was expecting a worse time, but it was relatively smooth. A great board!
