Customizing the "Machine" operating area
8.11 User status display (OEM)
Alternatively, you can use the following parameters for the definition:
● USER_ICON_BASE
This means that 32 bits are available with UI_0 (highest bit) to UI_31 (lowest bit).
Example: USER_ICON_BASE=DB80.DBB0
⇒ UI_0 = DB80DBX3.0 and UI_31 = DB80.DBX0.7
● USER_ICON_BASE256
This means that 256 bits are available with UI_0 (highest bit) to UI_255 (lowest bit).
Example: USER_ICON_BASE256=DB19.DBB80
⇒ UI_0 = DB19.DBX111.0 and UI_255 = DB19.DBX80.7
Example
[UserIcons]
USER_ICON_BASE=DB19.DBB80
; set the start byte of the PLC double word that displays the icons (DB19.DBD80)
UI_0 = icon1.png,4
; show icon1.png on position 4 if bit 0 (DB19.DBX83.0) is set
UI_1 = icon2.png,6
; show icon2.png on position 6 if bit 1 (DB19.DBX83.1) is set
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
active selection bit)
● Two alternative images for each of the permissible 16 positions, each position requires two
of the 32 selection bits (maximum 16 active selection bits at any one time)
