Bradley Programmable

Allen Bradley ControlLogix PLC Allen Bradley CompactLogix PLC and FlexLogix Allen Bradley PLC systems have been developed by Allen Bradley in the group of companies based Rockwell in the U.S.. It is a very advanced state of the art PLC system that uses the technologies that were developed by Rockwell Automation in the last 30 years.

There are 2 options Rockwell FlexLogix the L33 processor with 64K of memory and the L34 with 512K of memory. Apart from the specification memory operation of the units is identical.

An Allen Bradley FlexLogix provides a multi-purpose programmable controller. I / O can be distributed to locations close to sensors / actuators. Several commanders FlexLogix can be connected in distribution networks processing of larger systems.

Because it has a Logix control engine, a driver supports all FlexLogix Logix instruction, the task allocation model, and model data. A driver FlexLogix as other Logix controllers have a common approach to programming and configuration of I / S with RSLogix 5000 programming software. 1794 Flex I / O products offer a range of digital and I / S analog (including intelligent I E / S) in a rugged modular assembly. FlexLogix A simple system may consist of a single, independent of the Assembly with a driver and up to eight modules I / O. With expansion additional local further 8 modules can be added locally. FlexLogix systems can be mounted horizontally or vertically. An optional extension cable can interconnect be used for placing modules E / S closer to the field devices. FlexLogix In a more complex system, Ethernet, ControlNet or DeviceNet networks can be used to connect E / S multiple platforms E / S of links.

If you use multiple systems FlexLogix, you may want a central controller, as a ControlLogix controller to coordinate the FlexLogix drivers. If the driver uses FlexLogix E / S remote, place it on your own network. If you plan to share I / S, make sure the I / O is in a network that each controller can access locally.

FlexLogix Each controller can support:

8 E / S local modules.
8 large E / S local modules.
32 connections per card through communication ControlNet or EtherNet / IP.
(two cards maximum communication controller).
496 bytes 492 bytes input and output via DeviceNet.

Allen Bradley controllers FlexLogix have an RS-232 (DF1 protocol) port integrated the processor. Two independent communication interface module slots are available for a variety of communication options. These are, EtherNet / IP, ControlNet communications and DeviceNet cards. If you use modules of different communication interface in communication slots FlexLogix, you can save and route data between the RS-232, ControlNet, EtherNet / IP and DeviceNet networks.

EtherNet / IP is an industrial networking standard that supports implicit and explicit messages, and commercial uses outside the shelf Ethernet equipment and physical media.

ControlNet allows intelligent control devices to share high-speed information necessary for supervisory control, the coordination work of the cell, the operator interface, remote device configuration, programming and solution problems.

DeviceNet offers high-speed access to plant floor data from a wide range of devices on the ground floor and offers a significant reduction in wiring
