PCB screen shot showing MVI56E-SIE command to send INT data to DB1
address 0:
Row 1 in the SIMATICS Manager screen shot below shows the data transferred
from the SIE.DATA.WriteData[0] controller tag in RSLogix 5000.
If the data is broken up and displayed in binary format, it can be seen that the
binary data stored in the first byte of DB1.DBW 0 is identical to that stored in byte
address DB1.DBB 0. This is because the memory locations referenced by the
first byte of DB1.DBW 0 and by DB1.DBB0 are one and the same, as explained
previously.
