<strong>The</strong> main advantages of the system are:<br />
� Modular PLC system, which can fit to different requirements and price/per<strong>for</strong>mance levels<br />
� Standard PLC I/O modules support interfacing to all kind of control signals and to most of<br />
communication protocols.<br />
� High-speed intelligent co-processor modules take the control of fast blow-moulding tasks.<br />
Dedicated control algorithms are pre-programmed and easy to use.<br />
� Analog and digital I/O’s are included in the co-processor modules <strong>for</strong> fast and effective<br />
control of wall thickness and hydraulic motions.<br />
� Powerful HMI terminal with color touch screen and function keyboard helps the operator<br />
to operate the machine in a user-friendly, efficient and safe way.<br />
� Three types of recipes are available: machine data, product data and complete data.<br />
� Several security access levels are possible.<br />
� Multi-language HMI supports with up to 4 languages and different types of fonts (Asian<br />
fonts as well) are available.<br />
Functions of the <strong>PECS</strong> <strong>Blow</strong> <strong>Moulding</strong> <strong>Control</strong> <strong>System</strong><br />
Mitsubishi Electric offers complete blow-moulding solutions <strong>for</strong>:<br />
� Temperature control<br />
Auto-tuning temperature control with pretune.<br />
� Parison control<br />
Fast wall thickness control with simple profile programming.<br />
� Hydraulic control<br />
Accurate open-loop or closed- loop motion control.<br />
� Sequence control<br />
Standard ladder logic programming.<br />
Hydraulic <strong>Control</strong><br />
<strong>The</strong> hydraulic motion control with smooth and precise control is one of the most important<br />
features of the blow-moulding machines. While closed-loop control provides the ultimate<br />
positioning accuracy, the open-loop control may also be used to realize less demanding and<br />
cost sensitive positioning solutions.<br />
