Chapter 14 PLC Function |C200 Series
14-29
Mnemonic Function
AND Series connection- A contact
X0~X17 Y0~Y17 M0~M799 T0~159 C0~C79 D0~D399
Operand
9 9 9 9 9
－
The AND command is used in the series connection of A 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.
Command code: Operation:
LDI X1
Load contact B of
X1
AND X0
Connect to contact
A of X0 in series
Example

－
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.
Command code: Operation:
LD X1
Load contact A of
X1
ANI X0
Connect to contact
B of X0 in series

Mnemonic Function
OR Parallel connection- A contact
X0~X17 Y0~Y17 M0~M799 T0~159 C0~C79 D0~D399
Operand
9 9 9 9 9
－
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” calculations with the logic calculation result before the
contacts, thereafter, saving the result into the accumulative register.
