*1 For a Producer Tag during tag communications, it turns on only when communications with all the connected Consumer Tags are
stopped.
During tag communications, if one Producer Tag is connected to multiple Consumer Tags through multicast
communications, 'Class1 data link status' (Un\G7734272 to Un\G7734287) turns on if even one
communication operation is normal.
Note that if the connections with all Consumer Tags are not communicating or have a communication error,
'Class1 data link status' (Un\G7734272 to Un\G7734287) turns off.
The following table lists the assignments for each area.
The value of each bit indicates the connection number.
