Programming Manual - Basic & Applied Instruction Edition
7 Basic Instruction
7.5 LDP, LDF, ANDP, ANDF, ORP, ORF
2. LDF, ANDF, and ORF instructions (initial logical operation of falling/trailing edge pulse, serial
connection of falling/trailing edge pulse, and parallel connection of falling/trailing edge pulse)
In the example shown above, M0 or M1 is ON during only one operation cycle when X000 to X002 turn OFF from ON.
3. Bit specification of a data register (D)
*1
A bit in data register (D) can be specified as a device used in LDP, LDF, ANDP, ANDF, ORP and ORF instructions.
When specifying a bit in a data register, input "."
after a data register (D) number, and then input a
bit number (0 to F) consecutively.
Only 16-bit data registers are available.
Specify a bit number as "0, 1, 2, ... 9, A, B, ... F"
from the least significant bit.
Example: In the example shown on the left, LDP
contact turns ON (becomes
conductive) or OFF (becomes non-
conductive) when bit 3 of D0 turns ON
or OFF.
*1. This function is supported only in FX
3U /FX3UC PLCs.
