28.13 UNIDIRECTIONAL CONNECTION MODE
The unidirectional connection mode is used to control one or more processors from a remote site, for example over a
satellite link.
In this case, it will only be possible to send commands or new values for operating parameters one way, without the
ability to check whether the change has taken place or the current status.
A typical application is centralized remote control of processors installed at a scattered array of transmitting sites.
As explained in the previous paragraph dedicated to bidirectional connections, the software allows you to assign a
specific name to each processor (Target Name) and to group the processors themselves together (for example, those
corresponding to a region).
To return to the example given in the paragraph on direct (local) processor programming (3 processors in the Tuscany
region and another 4 in the Marches):
- To selectively program
only the Lucca processor, simply type ‘Lucca’ into the space reserved for the Target Name in
the unidirectional connection screen (the Group Name is not necessary, since the Target Name already uniquely
identifies a processor).
- To program selectively all (and only) the processors in Tuscany
, simply enter ‘Tuscany’ into the space reserved for
the Group Name in the unidirectional connection screen (the Target Name is not necessary)
- Finally, to program all processors the same regardless of their geographical position, you may enter the
password ALL directly into the box for the Target Name or Group Name.
Each processor ‘responds’ to the commands sent remotely (via the serial port 2) ONLY IF the Target Name
and/or Group Name coincide, or if the password ALL is present.
Once the remote connection (on serial port 2 of the processor) has been established, the basic screen of the
control software will be as follows:
