  1. Reading the manual is one way.
  2. Contacting Siemens' Technical Helpline by telephone and talking it through with a specialist there is another.
  3. Hanging about and waiting for some knowledgeable person to be bothered to respond on CR4 is a very poor third.

A hammer would probably work in the first direction.

"Healthy" status means there are no faults or issues in the system and the system is operating correctly.

"Unhealthy" status means there is a fault and/or issue in the system.

Faults and/or issues can be "minor" or "Major".

Minor means the system can operate but is limited and usually is automatically reset after the cause is repaired/removed.

Major means the system is stopped and inoperable until cause of the issue/fault has been removed/corrected and the system major fault table has been reset.

To make it "Healthy" you must correct, repair, and/or replace anything and everything that is not operating properly in the system. (I/O, Pwr. Supply, System backplane, card, communication system, etc.)

To make it unhealthy you just need to create an issue/fault but be careful as you could easily cause damage that is irreversible and for sure costly.

NEVER MAKE A SYSTEM UNHEALTHY WHEN IT IS ONLINE AND OPERATING AS YOU HAVE NO CONTROL OVER THE OUTCOME.
