jmeierhofer opened a new pull request, #16160:
URL: https://github.com/apache/camel/pull/16160

   
   # Description
   When Camel can not establish the connection to the S7 PLC, the component is 
throwing follow-up exceptions which are causing the application start up to 
fail and which hide the real connection issue.
   - Added isConnected() to endpoint which checks if connection is null. This 
method is public to allow external logic to check if endpoint is really 
connected.
   - Moved canWrite() call to be checked only when connected or re-connected.
   - Added additional canWrite() check after reconnectIfNeeded()
   
   Steps to reproduce:
   - Add Camel route with S7 driver
   - PLC is not available
   - Connection failure
   - Additional NullPointerExceptions are thrown
