If YY=0,
the encoder link error status C2ERR at the time of error detection appears.
If YY=1, 2, or 3,
the transferred frame information C2MTINF appears.
If YY=4,
the network address of the responding device appears.
If YY=5,
the received frame information C2RXINF appears.
If YY=6,
the number of parameter that caused the alarm appears.
1 = Not all the necessary parameters are received.
2 = Basic information on communication is incompatible.
4 = Protocol version on communication is incompatible.
