Hi to everybody. I need to read the first 12 characters of the message that a barcode reader sends to the ascii card (1734-rs232 ascii) and I can't do it. The problem is that the message that the barcode reader sends is 170 characters, so the plc sees that the XX.ReceiveRecordNumber increases by 2 because it overwrites the data of the first part of the message and I have the characters in the buffer from 129 to 170.
How could I capture the data of the first message? I really need to read the first 12 bytes from the barcode reader message.
Thanks a lot.
