 F_TRIG
F_TRIG assigns TRUE to output signal Q for one task period only when input signal Clk changes to
FALSE. Otherwise, the value of Q is FALSE.
 Down
The functions of the F_TRIG instruction and the Down instruction are exactly the same. The Clk vari-
able of the F_TRIG instruction corresponds to the In variable of the Down instruction. The Q variable
corresponds to the Out variable.
