■ANDP, ANDF
• ANDP is a rising edge pulse series connection instruction and ANDF is a falling edge pulse series connection instruction.
These instructions perform an AND operation with the previous operation result, and output the operation result. The
following table lists the on/off information used by the ANDP and ANDF instructions.

• If the ANDP instruction is used in the program written in ST or FBD/LD language, ENO turns on when the result of AND
operation between EN and the rising edge of the specified bit device (s) is on. EN will not be an execution condition.
• If the ANDF instruction is used in the program written in ST or FBD/LD language, ENO turns on when the result of AND
operation between EN and the falling edge of the specified bit device (s) is on. EN will not be an execution condition.
■ORP, ORF
• ORP is a rising edge pulse parallel connection instruction and ORF is a falling edge pulse parallel connection instruction.
These instructions perform an OR operation with the previous operation result, and output the operation result. The
following table lists the on/off information used by the ORP and ORF instructions.

between EN and the rising edge of the specified bit device (s) is on. EN will not be an execution condition.
• If the ORF instruction is used in the program written in ST or FBD/LD language, ENO turns when the result of OR operation
between EN and the falling edge of the specified bit device (s) is on. EN will not be an execution condition.
