SLC M0 File
The SLC M0 file is a 256 word file that can be used to transfer a large
quantity of information to the module with a single SLC instruction.
Transferring data by using this file can take several scans and more
time than by using the output image table.
The first 150 words are used for sending data to DeviceNet nodes. The
next 74 words are reserved for future use, the next 32 words are used
for explicit message program control, and the final 139 words are
used for pass-through.
Please see page 133 for more details on the mapping of the input and
output image tables and the M1 and M0 files.
