How it works

The latest evolution of the MicroNet™ control system that has been developed for Aero LM product lines.

It meets the current GE production standard for the LM2500 and the LM6000 product lines.

System interfaces with existing field devices and on-engine hardware providing core fuel control, package sequencing and protection. 

Combines both the Mark VI and the Fanuc90-70 PLC into a single controller and chassis. 

The MicroNet™ Plus Control System provides high-speed closed loop control, system sequencing, auxiliary system control, surge control, monitoring/alarming and station control.

The “Plus” features a series of product enhancements/upgrades:

  • Single or Redundant System Configuration (Dual power supplies, dual CPU’s) to provide high availability
  • Synchronized Memory – ensures that both CPUs use the same operating information in every rate group
  • 1 ms Transfer
  • On-line Reparability
  • New Motorola 5200 Processor
  • Real Time Network
