Note: On Allen-Bradley PLCs, reads and writes that extend beyond the end of an RMC register
file will continue into the next file or files. This is particularly useful on the ControlLogix, which
allows reading large amounts of data with a single MSG block. For example, by reading 2048
integers starting at N9:0 in the RMC, the entire Event Step table can be read into the
ControlLogix.
The register map for addressing the fields in the event step table is as follows:
