2. Control System
A control system is a device, or set of devices, that
manages, commands, directs or regulates the
behavior of other device(s) or system(s).
Industrial control systems are used in industrial
production for controlling an equipment or a
machine.
8. HMI (Human Machine Interface)
Provide a visible way for operators
to view and control plant
Provide operating data so management can
improve equipment and procedures
14. PLC
To provide a interface to plant equipment
Provide logic to allow interlocking and operation of equipment
Insight into the equipment and how it works
Metso is diverse in many hardware manufactures

This slide was created to give a general understanding of all parts of a control system. The red line shows how electrical power is transformed and distributed to the plant. The blue indicates signals to control. These are signals from sensors, or signals to command action to the plant. They can be wired, wireless, or some form of communication highway.
Power system designs are something that Metso is very familiar with. Our large equipment requires large motors to run, move, or function. We have even wound motor coils around a mill system because a proper motor and drive system could not be purchased. These photos are from a turkey job that Metso did using MCC, switchgear, and medium voltage and low voltage drives.

It is important to select parts that can be scaled. This means can grow. Every system has its limit but it is important to know what the limit is. This will allow the entire system to handle additional equipment, features, and customization.
When the control systems are new there should be three scalable aspects to look at.
1) Communications (The network should not be loaded, this will make your screen updates slow, could cause PLC problems and jeopardize networked interlocking.)
2) Graphics (Every graphics system has a tag count. This is how many different pieces of data one can look at. It is important that this count is not to low. This could stop you from being allowed to create additional functionality. The good thing is s scan normally be easily upgraded but required a more expensive license)
3) PLC (Expansion in PLC can be measure in having:
Spare memory – to enhance and change the program
Spare IO points – wired to terminals in the panel
Spare slots – were new cards can be added and wired
Spare terminals in the panel or spare space to put terminals
Spare racks – were new racks and cards can be added)
Metso can do the total system of any size system. We can layout control room, MCC rooms, or distribution of all electrical components.

Each PLC “Programmable Logic Controller” contains:
Power supply
Processor
Communication Cards
IO - Inputs/Outputs Digital/Analog
This is what connects to the real world or the field instruments.
This also were the logic is put to make the plant run.
The logic can contain: interlocking, sequencing, group starts/stops, calculations, loop control.
The PLC although made for industrial applications still require an external enclosure. The enclosure also includes auxiliary equipment needed such as power supplies, breakers, and terminals. The enclosures are to keep all contents dry and at proper temperature.
The layout of the system should include all the details of required hardware. What networks are required and where do they run. In addition, knowing if there are any special requirements or interfaces that are needed.
Sizing:
Feed size is: +8 mm to -18mm
Harth layer size is: +12.5 mm to -18 mm
Product size is: +6 mm to -18 mm
Initial updraft drying is to preheat bottom layer (Car 7 Hearth layer) to not condense water in next zone
No flame radiation to pellets, All heated air
