M0/M1 Monitoring
The SLC 5/03, SLC 5/04, SLC 5/05 processors allow you to monitor the
actual state of each addressed M0/M1 address (or data table). The
highlighting appears normal when compared to the other processor
data files. The processor’s performance will be degraded to the degree
of M0/M1 referenced screen data. For example, if your screen has
only one M0/M1 element, degradation is minimal. If your screen has
69 M0/M1 elements, degradation is significant.
Transferring Data Between Processor Files and M0 or M1 Files
The processor does not contain an image of the M0 or M1 file. As a
result, you must edit and monitor M0 and M1 file data via instructions
in your ladder program. For example, you can copy a block of data
from a processor data file to an M0 or M1 data file or vice versa using
the COP instruction in your ladder program.
The COP instructions below copy data from a processor bit file and
integer file to an M0 file. For the example, assume the data is
configuration information affecting the operation of the specialty I/O
module.
IMPORTANT
This option is not supported by the SLC 5/02
processor.
