*1: The decimal forms are notated by K in the device lists in Chapter 5 and Chapter 6 in AH500 Programming
Manual, whereas K50 should be inputted in ISPSoft rather than merely 50.
*2: The floating-point numbers are notated by F/DF in the device lists in Chapter 5 and Chapter 6 in AH500
Programming Manual, whereas they are represented by decimal points in ISPSoft; for the floating-point
F500, one should input 500.0.
*3: The strings are notated by "$" in Chapter 5 and Chapter 6 in AH500 Programming Manual, whereas they
are represented by " " in ISPSoft; for the string of 1234, one should input "1234"in ISPSoft.
