Equipment Sequence
The following table lists the command instructions for Equipment Sequences.
The instructions are available for routines that use the Ladder Diagram and the
Structured Text programming languages. They are not available for use in routines
that use the Function Block and the Sequential Function Chart programming
languages.

Use the Attach to Equipment Sequence (SATT) instruction to take ownership of
an Equipment Sequence. An Equipment Sequence must be owned by a program
before the program can command it. A tag must be assigned to store the result
code of an SATT instruction.
The SATT instruction returns one of five result codes. Result code 0 indicates
that the SATT instruction ran successfully. The other four codes indicate that the
instruction did not run successfully and provide additional information about the
reason for the instruction failure.
