If you are using a SLC 5/02 Series B processor, add 1930 µs to the
program scan time for each bit instruction addressed to an M0 or M1
data file. If you are using a SLC 5/03 Series C processor, add 1160 µs.

If you are using a SLC 5/02 Series B processor, add 1580 µs plus
670 µs per word of data addressed to the M0 or M1 file. As shown
above, 34 words are copied from #B3:0 to M0:1.0. Therefore, this
adds 24360 µs to the scan time of the COP instruction. If you are
using a SLC 5/02 Series C processor, add 950 µs plus 400 µs per
word. This adds 14550 µs to the scan time of the COP instruction.

The SLC 5/03 processor access times depend on the instruction type.
Consult the table on B–5 for the correct access times to add. As an
example, if you use a COP to M file instruction like the one shown
above, add 772 µs plus 23 µs per word. This adds 1554 µs to the
SLC 5/03 processor scan time due to the COP instruction.

The SLC 5/04 processor access times depend on the instruction type.
Consult the table on B–5 for the correct access times to add. As an
example, if you use a COP to M file instruction like the one shown
above, add 735 µs plus 23 µs per word. This adds 1517 µs to the
SLC 5/04 processor scan time due to the COP instruction.
