Changed word number : 0102CH
Contents of the word after the change (hexadecimal):
3013H (binary notation: 0011 0000 0001 0011)
Changed bit information (hexadecimal):
0001H(binary notation: 0000 0000 0000 0001)
Check sum (hexadecimal) : 0DH
From the “changed word number” and “changed bit information”, it is ascertained
that the change relates to the touch switch allocated to bit 00 of word 0102CH, and
because “1” is set at the relevant position in the “contents of the word after the
change”, it is ascertained that the touch switch has been pressed (if the change is
to “OFF”, since the operation differs according to the type of touch switch, it cannot
be determined from a change in the bit status alone whether the touch switch has
been touched or released.)
