Logging user changes

To log user changes using TF8550 NuGet packages, the following steps must be observed and set in the TwinCAT HMI project:

1. Setting the configurator control:
• Create an instance of type FB_UserLoggingHmi in the PLC project if it does not already exist.
• Map the PLC symbol in the HMI project.
• Include the symbol at UserLoggerSymbol property of the PlcSymbols category of the Configurator control.
2. Logging controls from the TF8550 NuGet packages:
• Install NuGet package Beckhoff.TwinCAT.HMI.Controls or Beckhoff.TwinCAT.HMI.Temperature.
• In the controls, set the LogChangesByUser property from the User Changes Logging category to TRUE.
3. Logging further controls:
• Select a meaningful event of the control for which logging is to take place.
• Use function LogUserChanges or LogUserChangesSymbol from the NuGet package Beckhoff.TwinCAT.HMI.Controls and set transfer parameters.
4. Applying UserLoggingViewer control:
• Drag UserLoggingViewer control from the toolbox onto a content.
• Transfer the path containing the UserLog files to the control under the Path property of the File Config category using the virtual directories.
• The files are created by default under the path C:\Data\Machine\UserLog (the path can be adjusted via the PLC).
