Resetting the "Homed" status

The "Homed" status of a technology object is reset under the following conditions

(<TO>.StatusWord.X5 (HomingDone)):

●Technology objects with incremental actual values:

– Starting an "MC_Home" job with "Mode" = 3, 5, 8, 10

(After successful completion of the homing operation, the "Homed" status is reset.)

– Error in the encoder system, or encoder failure

– Restart of the technology object

– After POWER OFF -> POWER ON of the CPU

– Memory reset

– Modification of the encoder configuration

●Technology objects with absolute actual values:

– Error in sensor system/encoder failure

– Replacement of the CPU

– Modification of the encoder configuration

– Restoration of the CPU factory settings

– Transfer of a different project into the controller
