Contents of the response:
If K100 is stored in DT0 and K200 is stored in DT1 of the FP series PLC on
the other side, "%01$RD6400C8006F
on the other side as the response when the program is executed. The re-
ceived data is stored in the data registers as shown below.

Extracting the data register values from the PLC on the other side
In the program, the data segment of the response from the PLC on the other
side is converted to hexadecimal data using the F72 (AHEX) (hexadecimal
ASCII → hexadecimal data conversion) instruction and stored in DT50 and
DT51, only if the character string "$1" stored in DT1 detected as a comparison
instruction.
