• If there are no elements other than length, an element error occurs. (When using length, one or more
elements other than length are required.)
• If the calculation result exceeds the number of digits set with "Data Length", the excessive digit value is
discarded (invalidated). For example, if the data length is 2 bytes and the data size calculation results are
"123" bytes, the data length will be "23".
• If there is a non-conversion variable (variable length)/non-verified reception (character length variable) after
the length, and that section is not included in the length calculating range, arrange the static data
immediately after the non-conversion variable/non-verified reception.
• When the code type setting is "ASCII Hexadecimal", a mismatch will occur if a character string other than
"0" to "9", "A" to "F", and "a" to "f" is received.
• Use "0" to "9" or "A" to "F" when converting to ASCII characters during send.
• When arranging multiple length elements, none of the length calculating range may overlap.
• When arranging multiple length elements, the previous length calculating range may not exceed the
arranged length.
• A length element cannot be arranged at the final position of the packet elements.
