4.7 User status display (OEM)
Function
Additionally (or alternatively), PLC-controlled (DB x, DBB y) user icons (symbols) linked to
specific machine states can be output.
Procedure:
1.
Declaration of icons and positions
2. Control of icon call by the PLC
Enter the name of the user icons and the associated positions in the HEADER.INI file in the
[UserIcons] section under identifiers UI_0 to UI_31.
[UserIcons]
UI_0= <Icon_00.bmp> , <Position>
; UI_0: Identifiers
; Icon_00.bmp: Name of user icon (8 characters.bmp)
; Position: Display position (1 to 16)
...
UI_31= <Icon_31.bmp> , <Position>
USER_ICON_BASE = DBx.DBBy
DBx.DBBy:
Double word defined by user for controlling the icon selection. If a bit for a User
Icon is set, then the associated UI_x entry should exit, otherwise nothing is displayed. To
display an icon according to the above declaration, the PLC sets the corresponding bit in the
double word.
Example:
Display an icon assigned to UI_0 → bit 0
...
Display an icon assigned to UI_31 → set bit 31.
If the bit is reset by the PLC, the associated icon is cleared from the display.
Example:
UI_3=Icon_01.bmp,12.
If bit 3 is set, the "con_01.bmp" icon is displayed at the 12th position, provided another icon
with a higher identifier (>UI_3) and the same position (12) is not active.
Possible applications
With a unique selection, a maximum of 16 bits are set simultaneously in the 4 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)
● 2 alternative images for each of the permissible 16 positions, each position requires 2 of
the 32 selection bits (maximum 16 active selection bits at any one time)
