- There are not enough points from the device number designated by (D) to the last device number of the relevant device
to store all the linked character strings. (Error code: 82)
- The storing device numbers of the character strings designated by (S2) and (D) are overlapping. (Error code: 82)
- The character strings of (S1), (S2), and (D) are longer than 255 characters. (Error code: 82)
