This is an excerpt from a recent educational article by Rockwell Automation:
The MicroLogix family of controllers provides five levels of control. Small on size, big on performance, the MicroLogix controller offers
control capabilities in an affordable, compact package. The MicroLogix 1400 controllers further enhance the MicroLogix family by expanding
the application coverage area while offering great new features at an affordable price
The MicroLogix 1400 controller is designed to broaden application coverage through the available embedded analog inputs, Ethernet
communication, faster high-speed counter (HSC), and pulse train output (PTO) capabilities. MicroLogix 1400 controllers maintain the same
critical features that you have come to expect from the MicroLogix 1100 controller, and expands that capability with more I/O, faster HSC/
PTO, and an additional serial port. MicroLogix 1400 controllers complement our low-end controllers for applications that require up to 256
digital I/O.
