My processbook have a few multi state symbols(Rectangle1, Rectangle2, Rectangle3......) and a trend symbol
Each symbol is assigned with analog tag and has 2 states(state1 is red, 2 is green)
Nothing happens when tag value is normal(state 2, green)
But If value is abnormal(state 1, red), I would like to add trace value of symbol on trend automatically
How can I using VBA?
