WinCC Professional V13 SP1 – Simple Sample: bit triggered real time Trends

“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:

In this simple sample, points are plotted on trend view object by button click (the concept could be extended to controller commands).

There are two variants: On demand, where the plotting is done by change bit variable and cyclic selective, where the plotting is enable / disable para bit state.

Requirements:

WinCC Professional V13 SP1.

Project with a minimum configuration (stop button, tags, etc.).

Configuration main steps:

• Create four tags, two to simulate trends signals (HMI_Tag_1 and HMI_Tag_2 as integer), to control proposes (HMI_Tag_3 and HMI_Tag_4 as Boolean).

• As simulation proposes, drag & drop the tags to a screen. IO field will be created (with this it would be possible to input different values to the tags).

On demand

• Create a Data Log (Project tree → WinCC → Historical data → Data logs → <add new>)

  Configure the data log:

  • Create a Logging tag (Project tree → WinCC → Historical data → Logging tags (division) → <add new>; Process tag = HMI_Tag_1; Acquisition mode = on demand; Trigger tag = HMI_Tag_3)

  • Create a Logging tag (Project tree → WinCC → Historical data → Logging tags (division) → <add new>; Process tag = HMI_Tag_2; Acquisition mode = on demand; Trigger tag = HMI_Tag_4)

• Place on screen the object “Trend view” (Toolbox → controls)

• Configure the Trend view:

  • Trend View → Properties → Trend → <Add new>

  • In the created line, configure: Data Source: Source Type = Logging tags; Tag = Data_log_1\Logging_tag_1

  • Trend View → Properties → Trend → <Add new>

  • In the created line, configure: Data Source: Source Type = Logging tags; Tag = Data_log_1\Logging_tag_2

Cyclic Selective

• Create a Data Log (Project tree → WinCC → Historical data → Data logs → <add new>)

  Configure the data log:

  • Create a Logging tag (Project tree → WinCC → Historical data → Logging tags (division) → <add new>; Process tag = HMI_Tag_1; Acquisition mode = Cyclic selective; Trigger tag = HMI_Tag_3)

  • Create a Logging tag (Project tree → WinCC → Historical data → Logging tags (division) → <add new>; Process tag = HMI_Tag_2; Acquisition mode = Cyclic selective; Trigger tag = HMI_Tag_4)

• Place on screen the object “Trend view” (Toolbox → controls)

• Configure the Trend view:

  • Trend View → Properties → Trend → <Add new>

  • In the created line, configure: Data Source: Source Type = Logging tags; Tag = Data_log_1\Logging_tag_1

  • Trend View → Properties → Trend → <Add new>

  • In the created line, configure: Data Source: Source Type = Logging tags; Tag = Data_log_1\Logging_tag_2
