MicroLogix 1100 Controllers

Product Overview

System Overview

With online editing and a built-in 10/100 Mbps EtherNet/IP port for peer-to-peer messaging the MicroLogix 1100 controller adds greater connectivity and application coverage to the MicroLogix family of Allen-Bradley controllers. There are 10 digital inputs, 6 digital outputs, and 2 analog inputs on every controller, with the ability to add digital, analog, RTD, and thermocouple modules to customize the controller for your application. On versions of the controller with DC inputs, there is a high-speed counter, and on the DC output version, two PTO/PWM (pulse train outputs and pulse width modulated) outputs, enabling the controller to support simple motion applications.

Benefits

• Online Editing—modifications can be made to a program while it is running, making fine tuning of an operating control system possible, including PID loops. Not only does this feature reduce development time, but it aids in troubleshooting.
  
• Built-in LCD—lets you monitor data within the controller, optionally modify that data and interact with the control program. The LCD displays status for embedded digital I/O and controller functions, and acts as a pair of digital trim pots to allow a user to tweak and tune a program.
  
• EtherNet/IP Port—for peer-to-peer messaging offers users high-speed connectivity between controllers and the ability to access, monitor and program from the factory floor to anywhere an Ethernet connection is available.
  
• Isolated RS-232/RS-485 combo port—provides a host of different point-to-point and network protocols.
  
• Embedded Web Server—lets you custom configure data from the controller to be displayed as a web page.
  

Product Design

The MicroLogix 1100 has 10 digital inputs, 2 analog inputs and 6 digital outputs, and supports expansion I/O. Up to four 1762 I/O modules (also used on the MicroLogix 1200) may be added to the embedded I/O, providing application flexibility and support of up to 80 digital I/O.

• One embedded 20 kHz high-speed counter (on controllers with DC inputs)—The built-in independent high-speed counter uses 32-bit integers for extended range, features 8 modes of operation, and supports direct control of outputs independent of program scan.
  
• Two 20 kHz high-speed PTO/PWM outputs (on controllers with DC outputs).
  
• Digital trim potentiometers—Allow quick and easy adjustments of timers, counters, setpoints, and more.
  
• Program data security—Data file download protection lets a program be reloaded into the controller without overwriting protected data.
  
• Floating Point Data Files—You can create data files that can contain up to 256 IEEE-754 floating point values.
  
• Memory modules—Memory backup provides protection and transportability for programs and data.
  
• Four interrupt inputs—Interrupt inputs let the controller scan a specific program file (subroutine) when an input condition is detected from a sensor or field device.
  
• Real-Time Clock—embedded in every controller.
  

Communication

The combo Communication Channel 0 port provides isolated RS-232 and RS-485 electrical compatibility (on separate pins). This port supports the same protocols as the MicroLogix 1200 and MicroLogix 1500:

• DF1 Full Duplex / DF1 Half Duplex Master & Slave / DF1 Radio Modem.
  
• DH-485 (supported directly using the 1763-NC01 RS-485 cable on this port; or using the RS-232 port and existing cables, a 1761-NET-AIC and external power is required for networking).
  
• Modbus™ RTU Master and RTU Slave (supported directly using the 1763-NC01 RS-485 cable on this port, or using the RS-232 port and existing cables, a 1761-NET-AIC and external power is required for networking.
  
• ASCII.
  

Communication Channel 1 with embedded RJ45 port supports EtherNet/IP for peer-to-peer messaging:

• 10/100 Mbps port with support for BOOTP & DHCP capability directly from the controller.
  
• Automatically assign IP address through DHCP or BOOTP, or configure using RSLogix 500 programming software.
  
• Monitor your IP address through the LCD screen (or use write-on nameplate).
  
• Supports CIP.
  
• Allows controllers to exchange data with other controllers through messaging (does not support scanning of I/O on Ethernet adapters).
