Tips and tricks

  • Use Bluetooth repro to distribute sound inside the building
  • Use a long range Bluetooth dongle
  • To simplify distribution of PLC of PUB file, add it into PLC web root. The application will automatically download it:
    1. In Mosaic, open "Project Manager/Sw/Export Files/Sending Files To PLC"
    2. Set "Auto send newer files to PLC" and "Send assembler file (.pub)" to true
    3. Set "Shorter file name" to: "www\var"
    4. NOTE: It doesn't work if you have PLC name shorter then 9 characters.
