bar code reader
Barcode readers, connected via RS232 to the COM port of the PC, are the simplest variant of barcode readers in industrial environments. These barcode readers normally supply a character string with the barcode information after the scan. The OPC Router Plug-in for generic bar code readers enables the reception and further processing of the character string.
That’s how easy it is.
The generic barcode reader plug-in does not have a transfer object, since the data is made available by the trigger object after receipt.
The generic barcode reader plug-in provides a receive trigger for barcodes. After receipt, the transfer is triggered and the barcode including all basic data is available in a data field.
The generic barcode reader plug-in does not use browsing.
