27.1 FNC210 – FDEL / Deleting Data from Tables
27.1 FNC210 – FDEL / Deleting Data from Tables
Outline
This instruction deletes an arbitrary data from a data table.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (FDEL and FDELP)
"n"th data is deleted from a data table (stored in and later), and the deleted data is stored in .
"n+1"th data and later in the data table are shifted forward one by one, and the number of stored data is
subtracted by "−1".
Caution
• The device range used in a data table should be controlled by the user.
The data table has data starting from the next device ( +1) after indicating the number of
stored data.
→ Refer to the program example.
