3.2 Configuring the screen size
During the boot process the HMI logs in to the controller and transmits its display
size. This way, the controller can configure the size automatically. Therefore,
there is no need configure the display size manually. But in some cases, this fea-
ture might make sense.
Correct configuration of the display size is required to ensure the controller cor-
rectly executes the special functions Delete Screen , and Delete to End of Line
when displaying text strings (DisplayText commands).
To configure the screen size manually, proceed as follows:
1.
Enter the number of characters per line into MR 2805.
2.
Multiply the value contained in MR 2805 by the number of lines and enter the
result into MR 2804.
