LDP, ANDP, and ORP instructions for contacts detect the rising edge, and become active during one operation cycle
only at the rising edge of a specified bit device (that is, when the bit device turns ON from OFF).
Contact instructions LDF, ANDF and ORF detect the falling edge, and become active during one operation cycle only
at the falling edge of a specified bit device (that is, when the bit device turns OFF from ON).
