Q(m) : Starting address of the output data area for the target controller
• Q(m), Q(m+1), ..., Q(m+47) assume data memory that is divided at each byte (8-bits).
• SIx() is handled as unsigned 8-bit integer data. (x=2-7, 10-17)
• SIW(y) is handled as unsigned 16-bit integer data. (y=0 - 15)
• The upper byte and lower byte of SIW(y) correspond to Q(2y+1) and Q(2y) respectively.
• SID(z) is handled as signed 32-bit integer data. (z=2, 4, ..., 14)
• The upper word and lower word of SID(z) correspond to SIW(z+1) and SIW(n), respectively.
* For details on the functions that are assigned to each serial input/output data, refer to the separate Remote
I/O Manual.
* The reserved area cannot be used.
