Connection diagnostics
Description
When you establish an online connection to a device in SIMATIC PDM, the following points
are checked while the connection is being established:
● Device type
● Device (TAG)
● Changes made to the device that have not yet been saved in the project
If a connection is aborted, SIMATIC PDM automatically attempts to establish a new connection.
Any errors that occur are displayed and logged.
If a device has not accepted the data in an identical manner, the values that are written to the
device and the actual values read back from the device can be displayed.
You can then decide whether or not to use the changed values in your project.
