(Process)
• LDP: Rising edge pulse operation start
This instruction turns on only at the rising edge (off to on) of the specified bit device.
• LDF: Falling edge pulse operation start
This instruction turns on only at the falling edge (on to off) of the specified bit device.
• ANDP: Rising edge pulse series connection, ANDF: Falling edge pulse series connection
These instructions perform an AND operation with the previous operation result.
• ORP: Rising edge pulse parallel connection, ORF: Falling edge pulse parallel connection
These instructions perform an OR operation with the previous operation result.
