Answer Posted / bm
Scan time of DCS is more than the scan time of PLC when the
I/O's are digital.
Whereas the scan time of DCS is less than the scan time of
PLC when the I/O's are analog.
Hence DCS is better when analog signals are considered
whereas PLC is better when digital signals are considered.
However DCS do handle both analog and digital signals. It
can also have more no. of I/O's compared to PLC. Hence we
use DCS.
