A part of this project is ABB’s Freelance DCS system to control the manufacturing and pneumatic transportation lines. The system integrates many functions within one platform using digital communication. This enables operators to monitor the key parameters of polyamide’s production and to control the complex process from one location.
The Freelance system plays a crucial role during polyamide production - it is responsible for overseeing measurement and analytics as well as controlling electrical equipment like drives. A non-standard solution is based on two portable control tablets. They are an addition to the fixed stations located in the central control room. It is a practical method to enhance remote control features. Thanks to the portable solution, the operator may quickly respond to any irregularities detected on the installation.
“The tablets allow operators to move freely in the area of the controlled installations without the risk of losing information about the process. The communication between portable units and the central Freelance system is performed via a wireless network,” explains Remigiusz Rabsztyn from ABB’s Industrial Automation Division in Poland. The tablets are explosion-proof, therefore they may be used in zones with risks related to hazardous substances.
