GX Works2 Display Contact Expansion Technical Bulletin

This technical bulletin outlines display issues that may occur when using GX Works2 Ver.1.48A or later alongside earlier versions (including GX Developer), due to an expanded number of displayed contacts (9, 11, 13, 17, or 21). It specifies conditions where ladder programs may not display properly (background turning yellow) and provides corrective actions, such as adjusting the display contact count in the ladder diagram settings.
