Modern electronic controls have replaced older control systems, significantly impacting production plant operations and equipment requirements. These systems make life considerably easier for the operator and play a crucial role in data logging and error reduction.
One key advantage is that administration and registering of line controls are automatically stored and printed without errors. This automated, error-free data logging replaces manual recording, which was prone to mistakes. The ease of use and visual feedback provided by these controls also contribute to error reduction. For instance, scanner signals are now visible on the control screen and adjustable by operators, removing past frustrations and preventing errors caused by operators "working in the dark".
Reliability and reproducibility are directly linked to equipment designed for 'maintenance-free' operation. Unexpected stops are costly, and controls that help avoid mistakes leading to reject are essential, particularly as reject becomes more costly further down the production line. The automatic check provided by visual machine settings on screen helps reduce mistakes, contributing to lower costs.
