RQC, Rawmix Quality Control

IPA Technologies software laboratory suite of applications, largely for the cement factories, encompasses the basic requirements of cement laboratory analysis data and specific data calculations needed to measure the raw material compositions that will be useful to automatically control the material composition mixes within the process.

The TECH Lab software is part of the TECH Control Suite family of software components that encompasses various applications within the control system framework. The process of data mining, laboratory sample management, material composition calculations, control system PLC interfacing and blending control modes are all managed in this complete TECH Control Suite.




The CEMQC LIMS application uses database SQL storage technology to collect and store material compound results from a third party material sampling x-ray unit. CEMQC executes remote preparation requests to the host operating the x-ray unit and retrieves sampling results after completion. The samples are then organised into the CEMQC database for further analyses and calculations on various compound materials.

CEMQC relies on the host software x-ray unit to perform the sampling analysis. The host computer operating the x-ray communicates with the CEMQC through it’s built in IO interface driver and if required its specific protocol data exchange.


CEMQC Features



Standalone installation of CEMQC runs on the Microsoft Windows 7 Professional 32/64bit machine platform.

For a distributed client/server setup, CEMQC sits on a Microsoft Windows Server 2008 R2.

QUEUE System

The queue system allows preparations from different lab operators to queue their request to access the x-ray system.


Equipment Inventory

All analysing equipment is stored in the equipment inventory to allow lab users to select their equipment prior to their preparation sample.

The equipment x-ray connects to the CEMQC Communication Interface to communicate with the x-ray host.



CEMQC items and derived items are created once per material group and utilized by the lab user to configure their sampling arrangements for a given material analysis.



As a lab operator CEMQC allows you to prepare “virtual” preparations and sub-preparations regarding the sample. These preparations can then are queued and initiate a sample request to the x-ray unit.



All materials and sampling results are configured by the lab operator and generate the report on a schedule basis or on a demand request. Export to Excel and PDF format documents are available.



CEMQC allows trending of items and derived items stored in the database.


User Favourites

A lab operator or user can create favourites quick commands for faster recognition of their configured preparations and sample items.


Data Storage

All samples are stored in handled by SQL Windows 2008 Standard. These samples can be used by 3rd party tools to extract information from CEMQC.

View current and past samples in the sample database for analysis and reporting.


Sample Results

Once the host computer operating the x-ray unit completes the CEMQC request command to sample a cup in the x-ray, the Sample Results are presented to the user for analysing the results.

The lab operators can then accept, reject or Re-Test the sample again from the host computer.


Formulas Calculations

Lab operators can create formulas and apply the calculations to the receive samples.



THE RQC application is part of the TECH LAB to aid the blending quality of raw material mix in the process.

RQC is able to communicate to any PLC controllers or a DCS via a network protocol. Sampling data is received from CEMQC and or from another source through the TECH Runtime IO drivers. The sampling data is then used for calculations in the compositions defined in RQC.

The application is able to create multiple configurations of material feeders or as many licensed process mills purchased.

Communication Drivers

Various communication technologies can be interface to the RQC via the TECH Runtime IO driver’s model. RQC IO drivers can communicate on any Profibus DP compliant Master/Slave Stations, Ethernet-ControlLogix (future) and RS232 Serial communications.

Other RQC native drivers can be designed for other network technologies. Please contact your supplier for further details.


The RQC-View User Interaction

RQC comes with a neat design user interface to interact with the RQC engine running in the background.

The view allows the configuration of items, reporting, calculations and many more. All in the same view window.


Calculation Variables

Process calculations are created in the calculation area using user variables or systems variables. The calculation area views all your set of calculations. Users can create as many calculation sets and as many user variables needed for their material composition calculations.

Calculations entered into the RQC are processed immediately by the RQC Engine and updates the variables screen on each cycle.


RQC Configuration of material feeders

RQC allows you to pre configure the material feeders according to the plant configuration in the field. Mills can be added and displayed into the RQC View windows, the same as the view in the HMI.


Dynamic Status

Attach dynamic states to the RQC feeders according to your plant process.


Historical Gauges

View setpoint settings for the last 5 changes to determine the state of the control variable.


Formula Tool

Create powerful formulas using RQC TECH-FBox formula tool. Design the formula using RQC variables and insert the formula into the RQC engine.


Connect to the Process

RQC works with the TECH Runtime CTAG engine to pass process information from the PLC to the RQC application engine.

The Runtime CTAG engine is the gateway for external communication into any of the TECH Control Software Suite.


RQC Module Add-Ins

Specific customised calculations that are a requirement for a certain plant process can load a built-in RQC Calculation module right into the RQC engine.

These modules are developed upon request and purchased separately.


RQC Reporting Services

All calculation variables are stored and reported in 3 reporting modes, on-demand, Event Trigger and Schedule generation.


Trending Tool

RQC Trending tool allows user to log and trend calculation variables for analysis of the process.

Users can view spot and average data on a 1sec, 1min, 20min, 4hrs, 8hrs, 12hrs and 24hrs time horizon.
