ELAU has introduced the latest version of EPAS-4, its PacDrive Automation Software toolkit. The EPAS-4 Version 16 has a fully documented software template. Other new software functions include preventive maintenance. The new tool kit is for assembling programs such as building blocks, using the best aspects of all the IEC languages, including ladder logic. EPAS-4's new drag-and-drop template facilitates the IEC languages that are easier to program and visualize, especially in the various cases of servo machines.
