Core Control Function Architecture

CMT Memory Stick Workflow

Program deployment: Download the compiled control program to CMT memory stick through Control Builder M

System startup: After the control board is powered on, it automatically reads the configuration files (. cfg) and program files (. app) from the memory stick

Data exchange: Real time data during operation is synchronized to the memory stick according to the set cycle (1s~10min)

Fault recovery: When a system abnormality is detected, the latest valid backup data in the memory stick is automatically called up

Typical application scheme

Coordinated Control of Thermal Power Turbine

Configuration: Redundant deployment of 3 control boards, CMT memory sticks storing turbine start stop curves and load distribution strategies

Function:

Real time adjustment of valve opening (control accuracy ± 0.5%)

Memory stick automatic backup of PID parameters under variable load conditions

Support online modification of control strategies (through memory stick hot update program)

Intelligent warehousing and logistics system

Configuration: Single control board with dual CMT memory sticks (primary and backup redundancy)

Function:

Multi axis motion control (supporting 32 axis synchronization)

Memory stick stores coordinate data of each storage location and equipment calibration parameters

Quickly restore sorting system configuration through memory stick in case of malfunction

Installation and Maintenance Guide

1. CMT Memory Stick Operation Specification

Insertion/extraction: Be sure to operate in the power-off state, and hearing a "click" sound when inserting indicates that it is in place

Data backup: It is recommended to perform full backup through ABB Memory Tool software every week

Compatibility: Only supports ABB original CMT memory stick (part number: 3ASC25H205-01), third-party storage devices may cause system failure
