Copy program pictures to USB stick
The controller reads existing program pictures from USB \ ProgImage\ Image_xxx.jpg. Thereby
existing program pictures will be overwritten by new program pictures with the same name.
Be aware
To read program pictures from USB the path name must be exactly:
USB: \ProgImage\.
The picture files must have the name „Image_xxx.jpg“. xxx means a 3-digit number between
„001“ und „099“.
(see item 4.2.3, p. 13)
Please note
The setting is PIN protected if administrators are activated.
Only users with the right “Create programs” are permitted to execute the option.
