Receiving
When receiving command 0x00 the 'Data' section will look like this:

| 16 Bit | 16 Bit |
By Mode = 0b00 a device can query if the MX10 knows a certain device group (Object type). The MX10 responds (Mode = 0b11) with group and the known number of devices in the respective group.
note
Group Count for MX8, MX9 modules returns with unknown count (e.g. because request too early, auto-scan off, feedback error is present,...) the result is 0xFFFF.
