Summary:

This sample is based on an actual project where pump usage is controlled by the electricity tariff to minimize running costs.

The sample makes use SCADA BASIC to verify tariff times input as text fields (both syntax and sequence) and to calculate the current tariff and the allowed pumps. The tariff is checked once a minute.

The tariff is shown on the clock face using 4 “Pie” drawing elements. The angles of each “Pie” are linked to database variables using the VB properties list which changes the shape according to the entered times.
