4) Save the data as a project file.
5) Read the project file, go online, and
download the file to the network devices.
Additional Information
You can stop remote I/O communications with a specified slave to effectively disconnect the
slave from the network by changing *_CnctCmd (Disconnect/Connect Switches) to TRUE. You
can do this when a slave is replaced or to register a slave in the scan list in preparations to con-
nect it to the network at a later time. The Disconnect/Connect Switches, however, are cleared
when the power supply is turned OFF, so the bit must be changed back to TRUE from the user
program after the power turns ON in order for it to remain effective.
