PCT23MkII Control console

The PCT23MkII is a bench top process controlsystem comprising a process unit mounted

on an ABS plinth an electrical control consoleand control software which can be run onany Windows PC with a spare USB port

a) Process Unit

The process is modelled on an industrial hightemperature short time (HTST) pasteurisation processIn this process the product stream has to be kept ata predetermined temperature for a minimum timeusually for bacteriological purposes This is effectedby the use of a holding tube which delays theproduct stream thus posing particular process controlproblems and introducing the concept of lsquodead timersquo

Other reasons why the HTST process is a particularlysuitable basis for teaching process control are theuse of a three stage heat exchanger (recycle heatingand cooling) and the use of a divert valve to rejectinadequately treated product Again these importantindustrial principles pose real process controlproblems and help maintain the studentsrsquo interest

Further process control problems are illustrated by theuse of two feed tanks with different level sensor types

Solenoid driven valves control the filling and emptyingof these tanks These enable different level controlstrategies to be developed and provide startup andshutdown operational sequencing capability

The unit includes a wide range of instrumentation fortemperature and flow measurement It also includesa conductivity sensor enabling simple processconcentration experiments to be performed

The unit comprises

bull Feed system with peristaltic pump

bull Water heating unit with peristaltic pumpbull Water cooling system

bull Plate heat exchanger with holding tube

bull Flow sensor in feed line

bull Conductivity sensor

bull Four temperature sensors

bull Level sensor in product tank

bull Highlow level switches in washingreagent tank

bull 2-way solenoid valves for filling feed tanks andcooling water to exchanger

bull 3-way solenoid valves for selectingfeed tank and diverting waste product

bull Connections to the electrical console

b) Control Console

The control console provides the electrical interfaceand signal conditioning for the process module It alsoincludes a USB interface for a Windowsreg computerThe process module sensor outputs can be displayedin engineering units on an integral LED display Theoutputs are also available for external monitoring

The drive signals to the process module can beselected as either manual control from the front panelcontrol from a PC via the USB bus onoff control froman external source (eg the Armfield PCT19BR PLC)or analogue control from an external source (eg theArmfield PCT20H PID) The source signals for bothpumps and the heater are individually selectable

Electrical faults may be introduced into any of thelow voltage measurement or control signals by a faultemulator installed in the electrical console Faultsmay be inserted individually or in combination to suitthe studentrsquos ability The quick release fittings usedthroughout the process enable faults to be introducedinto the process pipework

The unit comprises

bull Product feed pump speed control

bull Heating fluid pump speed controlbull Heater power measurement and control

bull Temperature (x 4) flow level ampconductivity measurement

bull Digital inputsoutputs(from switchesto solenoid valves)

bull Simultaneous connection of all signals to PCT19BRvia 50 way IDC connector or PC via USB port

bull Front panel sockets for connection to accessories inparticular industrial controllers and chart recorder

c) Software

Included in the basic equipment supply is an advancededucational software package which implementsthe control functions The software displays a realtime process mimic diagram and includes PIDcontrol algorithms with user control over thekey parameters A number of predefined studentexercises are implemented such as alarm actions andacknowledgements different single PID loops cascadeand multiple PID loops

Included in the software is a sophisticated datalogging and graphical display capability This capabilitycan be used even when the control signals are derivedexternally or manually The data can be saved andrecalled or exported in Microsoftreg Excel format

Other facilities included in the software are a series ofpresentation screens to aid in the setting up using theequipment analysing the results etc This is backed upby a comprehensive Help system

Advanced users may wish to produce their owncontrol software using packages such as LabVIEWtrade

MatLab or lsquoCrsquo This is possible using the USB interfaceon the PCT23 as the low level software driver (DLL) isaccessible and interfacing instructions are provided

For more advanced use an optional software packagehas been developed for use with the ArmfieldPCT19BR to demonstrate SCADA This package (ordercode PCT23SCADA) enables the PLC to control theprocess and extracts the data from the PLC via anRS232 connection The PLC data is then displayed onthe mimic diagram giving the PC the supervisory roleof the SCADA implementation
