The operands are the same as those for the Ladder Diagram PATT instruction.
Guidelines for using the PATT Instruction
Guideline
Consider ownership if have multiple sequencers
that use a common equipment phase.
Remember that Logix Designer overrides the
controller.
Use the Result operand to validate ownership.

Format Description
Name of the equipment Equipment phase to own.
phase
immediate To let the instruction return a code
for its success or failure, enter a DINT
tag
tag in which to store the result code.
Otherwise, enter 0.
Details
Ownership makes sure that a program can command all the
equipment phases it needs and locks out any other
sequencers.
If using:
FactoryTalk Batch software to
also run sequences within this
controller
Multiple programs to command
the same equipment phase
None of the above
Regardless of whether a program or FactoryTalk Batch
software owns an equipment phase, the option exists to use
Logix Designer to override ownership and command the
equipment phase to a different state.
This:
Logix Designer
Controller (internal sequencer)
FactoryTalk Batch software
(external sequencer)
Use the Result operand to get a code that shows the success
or failure of the PATT instruction. To interpret the result code,
see the PATT Result Codes section below.
Chapter 7
Then:
Before executing the
sequence (process), take
ownership of all the
equipment phases that
the sequence uses.
No need to own the
equipment phases.

Controller (internal
sequencer), FactoryTalk
Batch software (external
sequencer)
