When the seq
uence executes, the Relinquish_Ownership action:
• Relinquishes ownership of the equipment phase.
• Clears the ownership flags (bits that the SFC set when it took ownership of
the equipment phases).
Using an action Qualifier of type P1 limits the action execution to the first scan of
that step.

Use the PCLF instruction to clear the failure code of an equipment phase.
The PCLF instruction clears the failure code for an equipment phase.
• Use only a PCLF instruction to clear the failure code of an equipment
phase.
• A CLR instruction, MOV instruction, or assignment (:=) does not change
the failure code of an equipment phase.
Make sure the equipment phase does not have other owners when using the PCLF
instruction. The PCLF instruction will not clear the failure code if Logix Designer,
HMI, FactoryTalk Batch software, or another program owns the equipment
phase.
• High priority HMI ownership is specific only to the CompactLogix 5370
and ControlLogix 5570 controllers.
