6 SEQUENCE INSTRUCTIONS
6.1 Contact Instructions
Pulse operation start, pulse series connection, pulse parallel
connection
LDP, LDF, ANDP, ANDF, ORP, ORF
• LDP: Rising edge pulse operation start instruction
This becomes conductive (ON) only at the rising edge (OFF to ON) of the bit device specified by (s).
• LDF: Falling edge pulse operation start instruction
This becomes conductive (ON) only at the falling edge (ON to OFF) of the bit device specified by (s).
• ANDP: Rising edge pulse series connection instruction/ANDF: Falling edge pulse series connection instruction
This instruction ANDs the bit device specified by (s) with the operation result so far, and uses the result as the operation
result.
• ORP: Rising edge pulse parallel connection/ORF: Falling edge pulse parallel connection
This instruction ORs the bit device specified by (s) with the operation result so far, and uses the result as the operation result.
