Mnemonic Function
ANI Series connection- B contact
X0~X17 Y0~Y17 M0~M159 T0~15 C0~C7 D0~D29
Operand
9 9 9 9 9 --
Explanations:
The ANI command is used in the series connection of B contact. The function of the command is to
readout the status of present specific series connection contacts first, and then to perform the “AND”
calculation with the logic calculation result before the contacts, thereafter, saving the result into the
accumulative register.
Program Example:
Ladder diagram: Command code: Operation:
LD X1 Load contact A of X1
ANI X0 Connect to contact B of
X0 in series
X0 X1
Y1
OUT Y1 Drive Y1 coil
Mnemonic Function
OR Parallel connection- A contact
X0~X17 Y0~Y17 M0~M159 T0~15 C0~C7 D0~D29
Operand
9 9 9 9 9 --
Explanations:
The OR command is used in the parallel connection of A contact. The function of the command is to
readout the status of present specific series connection contacts, and then to perform the “OR”
calculation with the logic calculation result before the contacts, thereafter, saving the result into the
accumulative register.
