SLC 5/02 Processor Example
M0:2.1 M1:3.1 M0:2.1
–––] [–– –––]/[–– –––( )––
1 1 10
If you are using an 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 an SLC 5/03 Series C processor, add 1160
µs.
COP
Copy FILE
Source #B3:0
Dest #M:1.0
Length 34
If you are using an 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 an 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.
