Any application managed by the TD240 terminal should therefore
be realized using both the development environments,
implementing therefore two different files strictly connected
between them.
The operation of the terminal anticipates a division of the time
dedicated
to graphics management (implemented with
TdDesigner) and of the time dedicated to the management of the
PLC (implemented with PLProg 4.xx).
The default setup foresees an equal division of the execution
cycle: the terminal will execute the instructions inherent for
graphics for 50% of the time, and the Ladder instructions of the
PLC for the other 50% (cyclically).
The time division is settable by the user (see chapter 5). An
example is shown below in which 80% of the time is dedicated to
the graphics and 20% to the PLC.
