Superimposition
With a non-unique selection (bits for multiple identifiers whose image is to be displayed at
the same position):
The image with the lower identifier number is superimposed with the image with the higher
identifier number for the same position. Non-unique selection can also be used with less
than 16 active selection bits. The PLC can deliberately use this superimposition to overlay
less important displays (with lower identifier numbers) with important displays (high identifier
numbers).
Note
If two HMI applications are assigned to one NC/PLC unit (M:N), the PLC must first determine
from the interface which of the HMI interfaces is active. Icons can be requested by the PLC
for the active HMI application only.
Possible applications
With a unique selection, a maximum of 16 bits are set simultaneously in the four selection
bytes for each of the different positions.
● 32 alternative images for a position, each selected with a different bit (currently only one
● Two alternative images for each of the permissible 16 positions, each position requires
● Combination thereof with a maximum total of 32 images for the maximum 16 positions
● More than 16 selection bits.
Configuring OEM texts
Machine manufacturers can display their own texts in the program directory and program
name lines. These texts cannot include % parameters as is possible in user texts. The lines
are divided into <OEM_NUMBER_TEXTFIELD> areas according to the entry in
HEADER.INI.
The data is provided in a user data block. The number of the data block and the exact offset
are declared in the HEADER.INI file. The following entries are available in the [OEMTextInfo]
section for this purpose:
[OEMTextInfo]
OEM_NUMBER_TEXTFIELD = 1 ; maximum of 3 text fields per line
OEM_TEXT_BASE = DBx.DBBy
