Allen-Bradley "MicroLogix 1100" PLC

The MicroLogix 1100 combines all the features you demand in a compact controller, with EtherNet/IP messaging, online editing, a built-in LCD screen on every controller and a powerful combination of I/O.
Key Features and Benefits
• Input options: AC, DC and analog (current or voltage)
• Output options: relay, TRIAC, MOSFET and analog (current or voltage)
• Both AC and DC powered controllers are available

Advanced networking
An RS-232 port provides the MicroLogix 1000 family with network connectivity through the DH485 peer-to-peer network>. Using the DeviceNet Interface (DNI) brings the fast response, low cost and reliability of open DeviceNet connectivity to all 14 MicroLogix models. SCADA/RTU and point-to-point communications capabilities are available via the DF1 Half- and Full-Duplex protocols.

Flexible I/O technology
Broad input and output specifications provide a flexible control solution.
• Built-in 10/100 Mbps EtherNet/IP port for peer-to-peer messaging – offers users high speed connectivity between controllers, with the ability to access, monitor and program from anywhere an Ethernet connection is available
• Online editing functionality – 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 reduce development time, but it aids in troubleshooting
• Embedded Web server – allows a user to custom configure data from the controller to be displayed as a web page
• Isolated RS-232/RS-485 combo port – provides a host of different point-to-point and network protocols
• Embedded LCD screen – allows user to monitor data within the controller, optionally modify that data, and interact with the control program. Displays status of 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

Additional Features
• One 20kHz embedded high-speed counter (on controllers with dc inputs)
• Two 20kHz high-speed PTO/PWM (on controllers with dc outputs)
• Two embedded analog inputs (0 - 10 dc, 10 bit resolution)
• A simple operator interface for messages and bit/integer input
• 4K words user program memory and 4K words user data memory
• Up to 128K bytes for data logging and 64K bytes for recipe

For small applications, the embedded I/O in this controller may represent all of the control required. 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 the 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 capabilities.

The MicroLogix 1100 also supports expansion I/O. Up to four of the 1762-I/O modules (also used by the MicroLogix 1200 controller) may be added to the embedded I/O, providing application flexibility and support of up to 80 digital I/O.

MicroLogix 1100 Communication

Communication Channel 0 port enhancement provides isolated RS-232 and RS-485 electrical compatibility (on separate pins). Use the 1763-NC01 cable to interface directly to RS-485 networks. 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 (if you use RS-232 port and existing cables, a 1761-AIC and external power is required for networking; DH-485 is also supported directly using the RS-485 cable on this port)
• Modbus™ RTU Master and RTU Slave (if you use RS-232 port and existing cables, a 1761-NET-AIC and external power is required for networking; Modbus RTU networking also supported directly using the RS-485 cable on this port)

Communication Channel 1 with embedded RJ-45 port supports EtherNet/IP for peer-to-peer messaging:
• 10/100 Mbps port with support for BOOTP, DHCP, & SNMP capability directly from the controller
• Automatically assign IP address through DHCP or BOOTP, or configure using RSLogix 500
• Monitor your IP address through the LCD Display (or use the write-on nameplate)
• Supports CIP, but not CSP (SLC 5/05 supports both)
• Allows controllers to exchange data with other controllers through messaging, but does not support scanning of I/O on Ethernet adapters

Expansion I/O
MicroLogix 1100 and MicroLogix 1200 Expansion I/O
Superior Functionality at a Low Cost

MicroLogix 1100 and 1200 I/O expansion modules provide superior functionality at a low cost. With a variety of modules, they complement and extend the capabilities of the MicroLogix 1100 controllers by maximizing flexibility of the I/O count and type.

MicroLogix 1100 and 1200 I/O has a modular, rackless design. Elimination of the I/O rack from the system enhances cost savings and reduces replacement parts inventory.

The MicroLogix 1100 and 1200 I/O package design allows modules to be either DIN rail or panel mounted. The DIN latches and screw mounting holes are an integral part of the package design.

• Rackless design, eliminating added system costs and inventory
• Small footprint, shrinking panel space
• Integral high-performance I/O bus
• Software keying to prevent incorrect positioning within the system
• Feature-rich I/O functionality addresses a wide range of applications
• ac/dc relay, 24V dc, and 120V ac voltages

Expansion Modules System Qualifier
Use the Expansion Modules System Qualifier tool to calculate the current consumption of your MicroLogix 1200 expansion I/O system and determine whether or not an expansion power supply is necessary.
