[Note] The devices marked with red dots:
The HG series operator interface is capable of reading barcode data of up to 30 digits. When barcode
data of less than 30 digits is read, “0000h” is written to all of the remaining devices.
For example, when 8-digit barcode data is read after reading an 13-digit barcode data, the 9th to 13th
digits of the previous data are overwritten by “0000h”. As a result, the Message Display displays the
barcode data of 8 digits only.
