Operands

OperandDescription
DEVThe first operand.
Entries are WORD data registers or constants.
This is the value to write to the table.

The signed value range is -32,768 ~ 32,767 (216).
The unsigned value range is 0 ~ 65,535 (216-1).
The Hexadecimal value range is H0000 ~ HFFFF.
TBLThe second operand.
Entries are only WORD data registers.
This is the starting address for the table.

Notice

Error Flag (F11.0) Notice

The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.

F11.0 turns ON when the data table exceeds the range of the corresponding data register.

Instruction Behavior

The FIFW and FIFWP instructions behave as follows:

  • If there is already data saved to TBL, DEV will be saved to the next available slot of TBL.
    • The overall amount of data saved in TBL will increase by 1.
  • The first value of TBL is an integer number representing the amount of data saved in TBL.
Execution Condition

The FIFW instruction must be used with a pulse contact or an open contact with the FIFWP instruction due to the instruction continuously executing.
If the execution goes past the last possible data register block number, an error occurs and F11.0 turns ON.
