SD928 Device number
This register stores the device number that detected device
memory data change (lower word)
1) Word devices (SD, T (current value), ST (current
value), C (current value), D, W, SW)
The device number that detected an error is stored.
Example: When SD927 stores 20 and SD928 stores 10,
"RAM ERROR" (error code: 1161) is detected at D10.
2) Bit devices (SM, X, Y, M, L, B, F, SB, V, S)
The device number that detected an error is stored in units of
16 points.
Example: When SD927 stores 9 and SD928 stores 48, "RAM
ERROR" (error code: 1161) is detected at any of B30 to B3F.
3) T (contact, coil), ST (contact, coil), C (contact, coil)
The device number that detected an error is stored in units of
8 points.
Example: When SD927 stores 14 and SD928 stores 48,
"RAM ERROR" (error code: 1161) is detected at any of T48
to T55.
4) When the device number cannot be determined
"0" (fixed value) is stored.
