How do I get CitectSCADA to read from a barcode scanner and which driver can I use?

Typical barcode readers use RS232 communications channel. Within Citect, you can define a COMX board and the appropriate Port and write a custom cicode using the ComRead() Cicode function to read data back from the barcode reader.
Alternatively you can also use the ASCII driver.

In the event you are using a USB type barcode reader, where COM port is not available, you will need to ensure that the manufacturer of the barcode reader provides software that can convert the USB port into a virtual com port.
