This message indicates the status of the unit at CAN node address ‘0x80’:
Oscillation Left limit is - 30.0°
( + right of 0°, - left of 0° )
[ Rotation Left limit = 0xFED4 | -300 ]
Oscillation Right limit is +45.0°
( + right of 0°, - left of 0° )
[ Rotation Right limit = 0x01C2 | +450 ]
Unit is oscillating
[ Flags = 0x80 ]
