 +Modbus communication can either be done through high-level access (especially useful for cases where using spindle control through an inverter such as a Delta VFD, Fuling DZB, etc), or through low-level access which allows the user to program the process via a PLC procedure. ​
  
 +High-level access is preferable for its ease of use. The settings for different inverters can be preloaded by going into Settings > Config > Technology > Mill/Lathe > Spindle, and the myCNC system will automatically attempt to send the message again should the sending fail (up to four times). For high-level access, please set the check mark to ON in the **RS485/​Modbus Communication** field in the **Settings > Config > Technology > Mill/Lathe > Spindle** window. ​

 +Low-level access is preferable for direct access to the hardware. This allows to program the communication through PLC, and is a very flexible (albeit less straightforward) method. For low-level access the check mark in the **RS485/​Modbus Communication** field in the **Settings > Config > Technology > Mill/Lathe > Spindle** window to OFF.
