Comparison Instructions

LTascii, LEascii, GTascii, and GEascii
The text string comparison instructions are convenient when you want to reorder text strings according
to the character codes. For example, the character codes for alphabet characters are in the same order
as the alphabet characters. This allows you to alphabetize.
• Do not use this instruction as the rightmost instruction on a rung. If you do, an error occurs on the
Sysmac Studio and you cannot transfer the user program to the Controller.
• If this instruction is used in a ladder diagram, the value of Out changes to FALSE if an error occurs in
the previous instruction on the rung.
• Specify text strings that contain only ASCII characters for In1 to InN.
• An error occurs in the following case. Out will be FALSE.
• One of the text strings in In1 to InN does not end in a NULL character.
