Precautions
• Only one inline ST can be created on a single line of a ladder program.
• Both a function block and inline ST box cannot be used on a single line of a ladder program.
• Creating an inline ST box at the position of an instruction corresponding to a contact creates an inline ST box at the position
of an instruction corresponding to a coil.
• Up to 2048 characters can be input in the inline ST. (A newline is counted as two characters.)
• Using a RETURN statement in the inline ST causes the processing in the inline ST box to end, instead of the processing of
the program block.
• No function block can be called from the inline ST.
• The inline ST uses the CJ instruction in conversion to control the operation of a program. When the contact of the inline ST
is off, the processing in the inline ST is not executed by the CJ instruction. Thus, for example, the device that turned on by
the assignment statement in the inline ST holds its output status even when the inline ST is not executed. For details on the
CJ instruction, refer to the following.
