Product Design

The MicroLogix 1200 controller and expansion I/O modules provide a modular, rackless control system designed for ease of installation and maintenance. Each MicroLogix 1200 controller includes a processor, built-in I/O, and power supply. Expansion I/O modules install to the right of the controller. Cables built into the I/O modules provide connection to the adjacent I/O module or controller. Controllers and I/O modules can be mounted either on a panel or on a DIN-rail. I/O on both controller and expansion I/O modules have finger-safe terminal blocks to meet global safety standards. The 40-I/O controllers have removable terminal blocks to facilitate ease of wiring and maintenance.

  • Four latching or pulse-catch inputs—Latching inputs let the controller capture and hold very brief (microsecond) signals for input processing.
  • 20k Hz high-speed counter—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.
  • Programmable Limit Switch Function—The Programmable Limit Switch function allows you to configure the high-speed counter to operate as a programmable limit switch or rotary cam switch.
  • Trim potentiometers—Two built-in 3/4-turn analog trim potentiometers with a digital output (range from 0 to 250) 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, real-time clock, or memory/real-time clock modules—Memory backup provides protection and transportability for programs and data. The real-time clock lets you easily solve time/date scheduling applications, and can be synchronized with an external source via a program instruction.
  • 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.

Operator Interfaces

Many Allen-Bradley operator interface products can be used with MicroLogix 1200 controllers. The PanelView 300 Micro operator interface is a small, low cost, easy-to-use operator interface that is designed for use with the MicroLogix 1200 controller.


Product Design

The MicroLogix 1400 system offers higher I/O count, faster high-speed counter/PTO, and enhanced network capabilities. MicroLogix 1400 controllers without embedded analog come with 32 digital I/O count, while analog versions have 32 digital I/O and 6 analog I/O. All versions can be expanded using up to seven 1762 I/O modules — the same I/O modules that MicroLogix 1100 and 1200 controllers utilize.

The MicroLogix 1400 controller houses embedded inputs, outputs, power supply, and communication ports. It also provides the interface to expansion I/O when required by an application.

You can create long-integer data files (32-bit signed integer, ±2 billion) for use with math and embedded high-speed I/O instructions. You can also create floating point data files, each of which can contain up to 256 IEEE-754 floating point data elements.

The MicroLogix 1500 processes a typical 1K word user program (including bit, timer, counter, and math instructions) in approximately 1ms. Programs are created using Windows-based RSLogix 500 programming software. Programs written for other Allen-Bradley MicroLogix and SLC 500 controllers can be easily modified for use with the MicroLogix 1500 controller.

Two built-in 3/4-turn analog trim potentiometers with a digital output (range from 0 to 250) allow quick and easy adjustments of timers, counters, set points, and more. The optional Data Access Tool (catalog number 1764-DAT) adds the functions of 48 electronic push buttons, 48 electronic digital trim potentiometers, and two function keys. Trim potentiometer and Data Access Tool data is available to the user program through built-in function files.

The MicroLogix 1500 processor supports backplane messaging, which allows the processor to read or write data to other devices on DeviceNet. PCCC and CIP messaging are supported. Processor memory includes function files that store user-specified configuration data for system resources:


  • Selectable Timed Interrupts
  • Event Input Interrupt
  • High-Speed Counters
  • Pulse Train Output
  • Pulse Width Modulation
  • Base Hardware Information
  • Memory Module
  • Data Access Tool
  • Trim Potentiometers

  • Communication Status
  • I/O Status
  • Programmable Limit Switch
  • Recipe Data
SLC Processors

The SLC processors offer a wide range of choices in memory, I/O capacity, instruction set, and communication ports to allow you to tailor a control system to your exact application requirements. These products have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.

SLC 5/01 processors let you configure modular controllers of up to 960 I/O and a 1K- or 4K-instruction memory capacity.

SLC 5/02 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs nominally and a 4K-instruction memory. By installing an optional scanner module into one of the 30 I/O module slots, you can add ControlNet I/O, DeviceNet I/O, or Universal Remote I/O to the system. They offer 19 additional instructions, including a message instruction for initiating peer-to peer communication.

SLC 5/03 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of 8K, 16K, or 32K words. In addition to the features of the SLC 5/02, they have a second built-in communication port—an RS-232-C port that can be configured for ASCII or DF1 protocol, and can be configured for connection to a 1761-NET-AIC converter to provide access to a DH-485 network. SLC 5/03 processors provide bit-instruction execution times of 0.44 ms and an overall system throughput of up to 10 times faster than competitive processors. Additional capabilities include: floating-point math, online programming and run-time editing, flash memory upgrades, built-in key-switch, and a built-in real-time clock and calendar.

SLC 5/04 and 5/05 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of either 16K, 32K, or 64K words. They have all the features of the SLC 5/03 processors, plus a faster communication port and shorter execution times (bit-instruction execution times of 0.37ms). Instead of a DH-485 port, the SLC 5/04 has a built-in DH+ port for communication with other SLC 5/04 and PLC processors, operator interfaces, and programming terminals. Communication via the DH+ network is three times faster than DH-485 communication. SLC 5/05 processors provide a 10/100BASE-T, 10 or 100 Mbps Ethernet port.
