FXCPU Structured Programming Manual
[Basic & Applied Instruction]
Function and operation explanation
1. 16-bit operation (FINS/FINSP)
1) 16-bit data of the device specified by is inserted in "n"th position in a data table (stored in the device
specified by and later).
"n"th data and later in the data table are shifted backward one by one, and the number of stored data is
added by "1".
Cautions
1) The device range used in a data table should be controlled by the user.
The data table has the number of pieces of data, which is stored in , starting from the device after
the device that indicates the number of stored data .
→ Refer to the program example below.
2) The instruction is provided in the FX
3UC PLC Ver. 2.20 or later.

Error
An operation error is caused in the following cases. The error flag M8067 turns ON, and the error code is
stored in D8067.
1) When the table position "n" from the device specified by exceeds the "amount of data stored plus
one"
(Error code: K6706)
2) When the value "n" exceeds the device range of the data table specified by
(Error code: K6706)
3) When the FDEL instruction is executed under the condition "n ≤ 0" (Error code: K6706)
4) When the data table range exceeds the corresponding device range (Error code: K6706)
