Parallel connection- B contact

ORI
X0~X17
Operand
The ORI command is used in the parallel connection of B 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.
