Precautions

Before using the FB libraries in this reference manual, check the following precautions.
Description
The FBs in this reference manual do not include the error recovery processing. Prepare the error recovery processing separately to suit the user's system and
the expected operation.
Do not use the FBs in programs that are executed only once, such as a subroutine program or FOR-NEXT loop, because i_bEN (execution command) cannot
be turned off and the normal operation cannot be acquired. Always use the FBs in programs that can turn off the execution command.
The FBs require the configuration of a ladder block for every input label.
The FBs cannot be used in an interrupt program.
