7.2.2 The hardware definition
The hardware definition starts with specifying the types and the quantities of I/O interfaces
utilized by the specific system.
The following list contains the various options of I/O interfaces. We need to specify which types
of interfaces and how many of each type will be used in our system.
After defining which types of interfaces and how many of each will be utilized, we need to
define the addresses of the interfaces and some of them need some complimentary information
to be defined. Use the PAGE DOWN () key to reach the following table:
In our example there are 2 DC I/O
interfaces, one inside the DREAM and the
other inside the remote I/O at the nursery
There is 1 two wired RTU interface serving
the communication with RTUs 1 to 17
There is 1 Radio RTU interface serving the
communication with Radio RTUs 1 and 2
Interface DC No1 (resides inside the DREAM 2
enclosure), has 1 I/O board 16/8 (16 outputs, 8 inputs)
Interface DC No2 (resides in the REMOTE I/O unit), has
2 I/O boards of 16/8 (32 outputs, 16 inputs)
Interface No3 is the 2 wired RTU interface
Interface No4 is the radio RTU interface. The scanning
rate is set to 10.0 seconds.
