riggering screens
As can be seen from the above examples, there are two ways to display
screens with the NT2S-SF123B-EV2 :
1.
Keep all the message characters in the data memory ( the Omron
PLCs have lot of data registers which in most applications involving
simple digital controls are not used anyway ) and simply change the
offset register to display different screens.
The user can fill the data memory using the "data display editor" menu of
the PLC programming software.
2.
Note that the data memory as well as the program memory can be
used for embedding of data.
Of course, a combination of the two methods can be used to
optimize the memory usage.
