Let's Connect an
Operator Interface to a
Barcode Reader!
Practical Guide for Sample Program of the
Barcode Reader Connection
This text introduces an example of a system that imports barcode data captured by a barcode reader
into an operator interface, displaying imported data on the operator interface, and determining
OK/NG judgments.
Please open the O/I data "BCR2_BASIC_EN" and "BCR_ADVANCE_EN" stored in this Demo
version CD with the associated application software. Then, check the details of each program and
settings of this sample program while referring to the descriptions in this text. Display and entry area
