“Simple Samples” are small projects that demonstrate simple features. The target is give a quick overview about the theme and be used as start point for related discussions. Follow there are a short description and the configuration main steps.

Description:

By clicking on button (or filling a IO field) alarms near a specific date / time are showed in the Alarm view object.

Requirements:

WinCC Advanced V13 SP1.

Project with a minimum discrete alarm configuration (stop - See reference WinCC Advanced V13 SP1 – Simple Sample: Discrete Alarm,https://support.industry.siemens.com/tf/br/en/posts/135059/).

Configuration main steps:

Create a Date and Time internal variable (HMI Tags → Show all tag → <Add new> ; Name = “HMI_Tag_2”; Data type = “DateTime”.

Open a screen

Configure a alarm view (properties → General → Display = “Alarm Buffer”(or Alarm log); properties ->Display → Control tag for display area = “HMI_Tag_2”)

Create a IO Field (Toolbox → Elements)

Connect the IO Field to “HMI_Tag_2” (Properties → General → Tag: = “HMI_Tag_2”; Display format = “Data/Time”).

Variants:

The follow VB Scripts could be linked to buttons to set a preset value to “HMI_Tag_2” (offset as parameter):

As actual moment (now):

Sub VBFunction_2()

SmartTags("HMI_Tag_2").Value = Now()

End Sub

As actual moment (now) minus “offset” minutes:

Sub VBFunction_Min(ByVal offset)

SmartTags("HMI_Tag_2").Value = Now()- (offset/ 1440)

End Sub

As actual moment (now) minus “offset” hours:

Sub VBFunction_Hour(ByVal offset)

SmartTags("HMI_Tag_2").Value = Now()- (offset / 24)

End Sub

As actual moment (now) minus “offset” days:

Sub VBFunction_Day(ByVal offset)

SmartTags("HMI_Tag_2").Value = Now()- offset

End Sub
