Customize Traffic Light DI

Variant 1

Information

• A traffic light DI is a

  complex DI

  which contains sub-DIs in its construction.

  • Depending on the values of these sub-DIs, the traffic light DI can change the symbol.

• Traffic light DIs can be stored on a data field. It can be used to change its symbol (e.g. the color or font).

Procedure

• Open Customizer → System Customizer → Data Dictionary.

• Create a traffic light DI in the same data table as the DI to be checked and define the following parameters:

  • virtual =

  • Column type (DB type, DF type, PPMS type), DB length, and DF length as the DI to be checked

• Assign sub-DIs to the newly created traffic light DI in the Data Items module.

  • One and the same DI can be used as a sub-DI several times with different values in Value from and Value to

    • Example

      • The field is to be displayed blue for PR code A, yellow for B, and green for C. For this purpose, the PR code DI is assigned as a sub-DI trice.

  • You can also assign different DIs as a sub-DI.

    • Example

      • If a task is a summary task, the font is to be displayed bold and red if it is locked. For this purpose, the Summary task and TA locked sub-DIs are assigned to the traffic light DI.

• Define the sub-DIs as follows:

  • For Function = A:

  • Make a symbol assignment in the UDI symbol data field

    • Which symbol (or the symbol of which sub-DI) will be used depends on

      • the values in Value from and Value to

      • and the Pos. if the values of several sub-DIs simultaneously lie within the given frame.

  • Enter the respective values in the Value from and Value to data fields. Not only the absolute values, but also variables can be used here.

    • The traffic light takes effect if the sub-DIs lie within the frame defined here.

    • Select 2 in the Option data field if you want the traffic light to take effect for values that lie outside the given frame.

• Save.

Variant 2

Procedure

• Create a traffic light DI as a normal DI.

• Set the VR type = "PY".

• Customize the Python value range as described here.

• Assign the traffic light DI to the required data area.

Details

• PLANTA has defined threshold values for the traffic light colors red, yellow, green, which are controlled via global variables.

  • These threshold values can be adjusted individually in the Global Variables module (to be opened via Customizer → Master Data → Variables).

• The traffic light symbols overwrite the symbol stored in the Symbol ID data field.

Tip

• When customizing traffic lights, the data item can be assigned to itself as a child data item.

• This is helpful if you want to avoid using an additional traffic light data item.
