… 3 Design and function
Control system
Introduction
The control system is the interface to the ProKiln GAC400
system for the plant control system and for the probe operators.
The control system contains an electronic controller with all the
necessary input and output (I/O) connections required.
The control system contains all the needed software to operate
the complete system as well as the proprietary programming to
secure the best and safest operation of the system.
The control system of the ProKiln GAC400 has a layout based on
distributed I/O configuration connected via ProfiNet to the
various units. Each unit of the complete system (control cabinet,
retractor, and water unit) contains distributed I/O’s that report
to the central processing unit located in the control cabinet.
To access the control system, operators will use the Human
Machine Interface (HMI) located on the front of the control
cabinet.
If the ProKiln GAC400 is connected to an ABB AO2000-System
gas analysis system, a Modbus RTU serial connection is also
included and will exchange information between both parts in a
preconfigured setup.
The plant control system and any non-ABB gas analysis system
can also access the control system information via digital
potential-free I/O’s.
Control cabinet
The control cabinet must be placed in a safe location for the
operator, away from heat radiation and impact from dust. From
the control cabinet there must be a free line of sight to the
probe location, so that the operator can see the movements of
the retractor while it is being operated from the control cabinet.

The component layout will depend on the actual configuration as
shown in the electrical documentation as build documentation.
