Question: Why does the prolinx not report back a 100% of the time with a bar code read?

Question: Why does the prolinx not report back a 100% of the time with a bar code read?

Contrologix data table in plc, it is displayed backwards. As you can see there is a ASCii 10, 13 at end.

'$0F$AB' = decimal 4011 - this is the sequence number
'$00$00'
'$00$0F'
'C$02'
'00'
'37'
'07'
'74'
'$r9'
'$00$l'

This is the file that is configured

PLC interface code

does not past visually. oh well

but it follows the documentation
------------------------------------------------
Ethernet read

CIP Data Table Read
int_data[0]
INBOUND_SCANNER[0]

Then
Compare for the first word for new read

NEQ(INBOUND_SCANNER[0],last_INBOUND_scanned_index)XIC(MSG_INBOUND.DN)OTL(BC_INBOUND.BC_DONE);

Question: Why does the prolinx not report back a 100% of the time with a bar code read? The Prolinx is causing my bar code read rate to drop by 2% by NDFS
