Introduction & Overview

• Objectives• Know what the Qi is

•  Be able to describe the function of the Matroller

•  Be aware of comprehensive feed data O/P by the Qi

•  Will know what type of equipment is supported by the QiMPACT

Reference material: Qi – The BASICS.pdf

Qi Matroller position in a Batching System

• Last control component in the sequence• Receives Target and Material info • Reports back to Control system at the end of the Feed

Recipe Target &

Material Path

HMI PLC Qi Matroller

• Qi processes the Recipe One Material (Phase) at a time.

• Database of Materials used is kept in the Qi

Batch Server

Multiple Recipes

Functions – what is it and what does it do ?

• It’s a Weight indicator and Flow meter totaliser !

• Can be part of a Batching System OR stand alone control

• Does not store a recipe internally.

• Suitable for single valve control (single feed)

• Accurate Feeds at SPEED (High Flow Rates)– Uses P&G’s patented Predictive Control Algorithms

• Monitors Flow Rate during the Transfer cycle and continuously adjusts the cutoff point

– Very fast, 20 mS comparator for scales• Flowmeter even faster!

• Provides consistent Material Feed Interlocking– Consistency throughout the world!

• Provides Comprehensive Feed reports

• Qi Lite can handle two speed control

• GROUP FEED Capability (Qi Lite)

Qi Functional capabilities – not just accuracy

• Feed Accuracy at Speed– Maintains Feed accuracy at High Flow rates and varying Flow Rates !

• By means of sophisticated Predictive Control Algorithms (PAC)

• Material Feed management– Built in Feed Interlocking

• Will not allow simultaneous Feed In and Discharge out of the same Scale

– High limits, Low limits, silly Targets– Instrument accuracy crosschecking– Overlapping feeds for a more efficient process

• Feed Data Logging– Comprehensive data output at end of every feed

• Note: must be captured by Host Computer

– Data such as:• Net amount Fed, Feed duration time, Gross weight at start and end of Feed,

Average Flow rate, Flow rate and Spill at Cutoff, Internal Algorithm constants etc

• All this is built into, and comes standard with the Qi. Thus reducing the amount of code within the PLC, reducing cycle time and code writing time.

• This means a consistent solution to feed control throughout the World

• Simplifies maintenance and support

Review questions

• Does the Matroller require a PLC when performing batching functions?

• What are the three main functions of a Matroller?• Can the Matroller function as a standalone Scale display?
