When the Copy command is specified using the ID instruction execution request (Y14)
of antenna 1, the command reads the data of the ID tag of antenna 1 (copy source)
and writes the data to the ID tag of antenna 2 (copy destination).
When the Copy command is specified using the ID instruction execution request (Y1C)
of antenna 2, the command reads the data of the ID tag of antenna 2 (copy source)
and writes the data to the ID tag of antenna 1 (copy destination).
When the Copy command ends normally, ID instruction complete (X4, XC) of the copy
source turns ON.
(1) Copy source antenna
The copy source antenna reads from the ID tag the number of byte sets specified in
the number of processed points specification area (Un\G4, Un\G4004) from the
address specified in the head address specification area (Un\G3, Un\G4003).
The communication specifications available are trigger and auto only.

number of byte sets specified in the number of processed points specification area
(Un\G4, Un\G4004) from the address specified in the command option specification
area (Un\G5, Un\G4005).
The communication specification is not available for selection. Communication is
executed by a trigger.
