Equipment Phase Instructions
418 Rockwell Automation Publication 1756-RM006K-EN-P - November 2018
Avoid or plan for a result code = 24582. On each execution, the PATT instruction tries to take
ownership of the equipment phase. Once a program owns an
equipment phase, another execution of the PATT instruction
produces a result code = 24582. When using a PATT
instruction, either:
• Limit its execution to a single scan to avoid the 24582
result code.
• Include a result code = 24582 in conditions for
ownership.
When the sequence is done, relinquish
ownership.
To relinquish ownership, use a Detach from Equipment Phase
(PDET) instruction.
PATT Result Codes
If assigning a tag to store the result of a PATT instruction, the instruction returns
one of these codes when it executes:
Code (Dec) Description
0 The command was successful.
24579 Logix Designer or HMI already owns equipment phase. The caller is attached to the
equipment phase, but it is not the current commanding owner.
• This program now also owns the equipment phase.
• Since the Logix Designer or HMI is higher priority than a program, the program
cannot command the equipment phase.
• High priority HMI ownership is specific only to CompactLogix 5370 and
ControlLogix 5570 controllers.
24582 The program already owns the equipment phase.
24593 One of these already owns the equipment phase:
• External sequencer (FactoryTalk Batch software)
• Another program in the controller
24594 The equipment phase is unscheduled, inhibited, or in a task that is inhibited.
