• LDPI: Rising edge pulse NOT operation start instruction
This instruction becomes conductive (ON) at OFF, ON and the falling edge (ON to OFF) of the bit device specified by (s).
• LDFI: Falling edge pulse NOT operation start instruction
This instruction becomes conductive (ON) at the rising edge (OFF to ON), OFF and ON of the bit device specified by (s).
• ANDPI: Rising edge pulse NOT series connection instruction/ANDFI: Falling edge pulse NOT series connection instruction
This instruction ANDs the bit devices specified by (s) with the operation result so far, and uses the result as the operation
result.
• ORPI: Rising edge pulse NOT parallel connection instruction/ORFI: Falling edge pulse NOT parallel connection instruction
This instruction ORs the bit devices specified by (s) with the operation result so far, and uses the result as the operation result.
