VB Screens in the Level 2

The Human-Machine-Interface (HMI) screens and related client-side applications were developed with Visual Basic. Over fifty screens exist for the Level 2 package. Some screens, such as the summary screens for EAF, LMF, Caster and Meltshop overview,  are used in more than one sub-package (EAF Level 2, LMF Level 2, Caster Level 2, etc.). Figure 1 below is the LMF Summary screen.

Besides the HMI applications, there is a separate program that is also written in VB. It's a parameter editor used by a Level 2 administrator to edit Level 2 database parameters. For example, the name of the operators and shift leader, the chemical analysis of each grade, and recipe definition, etc, can be pre-entered into the Level 2 flat file database for Level 2. For example, as long as a grade name is assigned in the schedule, the chemical analysis specification (Aim, Min, Max value for every element, as showed in the above screen) is displayed automatically in the Level 2.
