When the Basic module is placed into the RUN mode, any data placed into
the SLC processor’s data table beginning with N12:0 is sent to the
1747-SCNR, which sends it to the 1747-ACN15 via ControlNet and then to
the Basic module. The Basic module sends the data out PRT1 and this data is
looped right back in the Basic module’s PRT2. The module sends the data to
the 1747-ACN15, which sends it to the SCNR via ControlNet. The SLC
processor then retrieves this data and places it into its data table beginning at
N13:0.
