NIBBLE/BYTE
D
Bit position of device number to save data converted
NIBBLE/BYTE
[Flag Set]

Description
Device Number
Error
For BCD4 when S’s value is other than 0~9.
For BCD8 when S’s value is other than 0~99.
F110
1) BCD4 (Nibble Binary Coded Decimal)
(1) Converts specified S device’s 4-bit BIN data to (0~9) BCD4 and saves in specified D device area.
(2) Error Flag (F110) will be set if S value is other than (0~9).
2) BCD8 (Byte Binary Coded Decimal)
(1) Converts specified S device’s 8-bit BIN data to (0~9) BCD8 and saves in specified D device area.
(2) Error Flag (F110) will be set if S value is other than (0~99).
3) Program Example
(1) If P00000 is On, ‘9’s Nibble data will be BCD converted to ‘h9’ from P0200’s No. 4 bit.
(2) If P00001 is On, ‘99’s Byte data will be BCD converted to ‘h99’ from P0400’s No. 8 bit.
BCD4 9 P02004
