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

If you are using an SLC 5/02 Series B processor, add 1580
µ
s plus
670
µ
s 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
µ
s to the scan time of the COP instruction. If you are
using an SLC 5/02 Series C processor, add 950
µ
s plus 400
µ
s per
word. This adds 14550
µ
s to the scan time of the COP instruction.
