software.

Synchronize date and time
In order to synchronize the date and time on the operating unit with the PLC, the
area pointer
Date/Time PLC must be set up in the project in ProTool/Pro CS.
During runtime, the operating unit accesses these data areas in the PLC for
reading purposes and synchronizes the date and time in the configured acquisition
cycle with the PLC. This data is provided, for example, in the message time
stamps issued in the message display.
Detailed information concerning the area pointers is provided in the
ProTool Configuring Windows-based Systems user’s guide, in the configuration
software online help and in the
Communication for Windows-based Systems user’s
manual.
