First Choice in Medium-sized Controllers

Featuring the big two essential features of online editing and EtherNet/IP port for programming and peer-to-peer messaging, the MicroLogix 1400 controller is one of the two in the MicroLogix range we recommend. Also featuring a built-in LCD screen for various functions, fast (100kHz) DC inputs and a digital trim pot for setting variable program parameters.

LCD Display and Cursor / Data Entry Buttons

MicroLogix 1400

The selector buttons are a bit dodgy, often requiring multiple presses to get the touch right, but the display is a valuable addition to the unit providing the following functions:

  • display of controller status, I/O status,
  • simple operator messages,
  • entry of configuration data such as network address
  • bit and integer data table manipulation.

Other MicroLogix 1400 Features

  • Datalogging and Recipe Storage
  • Floating Point mathematics capability
  • 6 Fast (100kHz) DC inputs on the base unit for pulse counting from flow meters, encoders etc.
  • Pulse Train Output (PTO) and Pulse Width Modulation for positioning applications.
  • RJ-45 port for EtherNet/IP, DNP3 over IP, and Modbus TCP.
  • Embedded Web Server for displaying data registers in tabular form
  • One RS-232 / RS-485 Combo Port for a range of protocols – DF1, DH-485, Modbus RTU Master/Slave, ASCII, DNP3 Slave.
  • Non-volatile battery backed RAM
  • Embedded Real Time Clock
  • Accessible with both RSLogix500 and RSLogix Micro Programming Software.
