|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 ControlLogixgateway 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.
|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.
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.
|CompactLogix is designed to provide a Logix solution for medium applications. Typically these applications are machine-level control applications with I/O requirements, network connectivity, and motion control requirements. A simple system can consist of a standalone controller with a single bank of I/O modules and DeviceNet communication. In a more complex system, add other networks and motion control. Multiple controllers can communicate across networks and share data.
Using CompactLogix controllers on EtherNet/IP or ControlNet networks, you have the means to cost-effectively integrate a simple machine or application into a plant-wide control system. For example, you can use aCompactLogix 1769-L35E controller to connect a suite of scalable products, such as the Allen-Bradley PanelView Plus operator interface, POINT I/O, and the PowerFlex 70 drive, for a full-scale integrated solution.
Both ends of the architecture provide a direct link from real-time production information to manufacturing quality or execution systems (and back again), providing a more accurate view of plant operations and more control options than ever before to achieve this integration.
|MicroLogix 1000 Controller
Based on the architecture of the market-leading SLC 500 controller family, the MicroLogix 1000 controller brings high-speed, powerful instructions and flexible communication to applications that demand compact, cost-effective solutions.
The MicroLogix 1000 controller is available in 10-point, 16-point, or 32-point digital I/O versions. Analog versions are also available with 20 digital I/O points, with 4 analog inputs (2 voltage and 2 current) and 1 analog output (configurable for either voltage or current).
The analog I/O circuitry for the MicroLogix 1000 controller is embedded into the base controller, not accomplished through add-on modules: so, it provides very high-speed, cost-effective analog performance.
The MicroLogix 1000 controller uses Rockwell Software RSLogix 500 programming software and shares a common instruction set with the MicroLogix 1100, MicroLogix 1200, MicroLogix 1500, and SLC 500families of controllers.
|MicroLogix 1100 Controller
The MicroLogix 1100 controller is our newest family of controllers to join the popular MicroLogix 1000, MicroLogix 1200, and MicroLogix 1500 controllers, and is designed to broaden application coverage through embedded analog inputs, Ethernet communication, and visualization capabilities. MicroLogix 1100 controllers maintain the same critical features you have come to expect from theMicroLogix family, and expand that capability to include true online editing. MicroLogix 1100 controllers complement our low-end controllers for applications that require up to 80 digital I/O.
Each MicroLogix 1100 controller contains 2 embedded analog inputs, with 10 digital inputs and 6 digital outputs. The controller can also expand its I/O capabilities by using the same modules as theMicroLogix 1200 controller. Up to four of the 1762 I/O modules can be used with a single MicroLogix 1100 controller.
Using the latest version of our world-class RSLogix 500 programming software, the MicroLogix 1100 controller can be programmed with an instruction set that is common with the MicroLogix 1000,MicroLogix 1200, MicroLogix 1500, and SLC 500 families of controllers.
RSLogix 500 Starter, Standard, and Professional applications all support the MicroLogix 1100 controller, including its online editing capabilities.
Each controller supports a built-in RS-232/RS-485 combo port for serial and networked communication and a second built-in EtherNet/IP port, which supports Ethernet peer-to-peer messaging.
An embedded LCD screen lets you monitor controller and I/O status, as well as make changes to bit and integer data.
|MicroLogix 1200 Controller
The MicroLogix 1200 controller provides more computing power and flexibility than the MicroLogix 1000 controller to solve a variety of application needs. Available in 24- and 40-point versions, the I/O count can be expanded by using rackless I/O modules. This results in larger control systems, greater application flexibility and expandability at a lower cost and reduced parts inventory. A field-upgradable flash operating system that helps to make sure you will always be up-to-date with the latest features, without having to replace hardware. The controller can be easily updated with the latest firmware via a website download.
