Extension function
When the extension function is validated by turning ON the M8167, the hexadecimal key pushing data of 0 to
F is stored in BIN.
Except for the following, this is same as the "function and operation explanation" given above.
FX
U PLC: V2.30 or lower has no extension function.
1. 16-bit operation(HKY)
Hexadecimal data entered by keys 0 to F is directly written into the device designated in .
1) Numerical value input by keys 0 to F
- If more than FFFF, the value overflows sequentially from the upper digits.
- Example:
In the case of input of 1 → 2 → 3 → B → F, "23BF" is stored in BIN in the device designated in .
That is, 1 overflows at the time of input of F.
2. 32-bit operation(DHKY)
Hexadecimal data entered by keys 0 to F is directly written into the device designated in .
1) Numerical value input by keys 0 to F
- If more than FFFFFFFF, the value overflows sequentially from the upper digits.
- Example:
In the case of input of 9 → 2 → 3 → B → F → A → F, "923BFAF" is stored in BIN.
