This setting determines whether the startup mode will be the mode set on the
Programming Console's mode switch or the mode set here in the PLC Setup.
Note If this setting specifies the mode set on the Programming Console's mode
switch (0) but a Programming Console isn't connected, the CPU Unit will auto-
matically enter RUN mode at startup. (This differs from the default operation
for CS-series CPU Units.)
