Processing details
• These instructions convert the 16-bit signed binary data (ANY16_U) in the label specified by (s) to 16-bit unsigned binary
data (ANY16_S), and store the converted data in the label specified by (d).
• The following figure shows a program example using the UINT2INT(P) instruction.
Ex.
The + instruction requires ANY16_S to be specified by the operand, and therefore, before the + instruction is executed, the
UINT2INT instruction is used to convert uLabel0 of ANY16_U to wLabel1 of ANY16_S.
The value in uLabel0 is stored in wLabel1 as is.
bSwitchA
bSwitchA: Bit
wLabel0, wLabel1: Word [signed]
uLabel0: Word [unsigned]/bit string [16 bits]
(1) The value is stored as is.
(2) The data type of the value is converted to the one of the operand in the + instruction, and the operation starts.
Operation error
There is no operation error.
