Honeywell MasterLogic PLC (ML200)

Honeywell MasterLogic PLC (ML200) is a programmable logic control system (PLC) compliant to IEC 61131.  With a compact footprint and high speed 42ns/step processor, Masterlogic PLC is suited to fast, discrete sequential control applications in a cost effective design. It can operate in a standalone manner, in a peer-to-peer environment, or in a SCADA topology with Experion® HS – please contact Fluidic for more details of the full Honeywell modular control system catalogue.


Honeywell Masterlogic ML200 PLC includes a wide range of modular components (the CPU, power supplies, discrete and analog, I/O modules, network modules, and racks) which are available in a variety of modules.  Masterlogic ML200 PLC has a dedicated Ethernet-based I/O bus controller which supplements the main, powerful CPU in I/O refresh to achieve high speed scanning.  Redundancy ensures high availability and peace of mind, especially for critical applications. Available with standard functions, Honeywell Masterlogic ML200 supports creation of new or user-defined functions within the IEC 61131 language. ML200 works in a loop-based, user-defined program where it waits for input and output at predefined intervals, and can perform self-diagnostics for system errors and trouble shooting. Built on open network standards, this programmable logic controller is integrated with the established Honeywell Experion platform.
