11.1.4 Creating a Program
Create the digital value setting program for performing the initial setting and outputting
analog values for remote device stations.
The following illustrates the relation between the remote device station’s I/O operations
and the user program when controlling the remote device station, and how the digital
value settings for the initial setting and analog outputs controls the system.
(The shaded areas indicate the devices that are actually used.)
: Default values are used for the initial settings except the analog output
enable/disable setting.
