Rung 2:2
Creation of output string for DL50. Message sending is initiated by discrete
input I:001/00 and controlled by the delay timer.
First the variable is converted from an integer to an ASCII string. (AIC)
Next the output string is assembled from the separate parts. (ACN)
Finally the output string is sent out to the DL50 through CH0. (AWT)
