I/O communications at star-
tup
Specifies I/O communications start/stop
after each slave on the scan list starts
(nodes that perform explicit message com-
munications must also be registered in the
scan list).
Sets Master start/stop (using a software
switch or the Configurator).
Performs I/O communications only with
slaves registered in the scan list. (Explicit
message nodes do not have to be registered
in the scan list.)
