Hello,
I am a relatively new Controls Engineer looking for some guidance on an issue I am having with transferring barcode scanner data.
Some quick bits of information:
Allen Bradley CompactLogix 5380 v 35
Zebra Barcode Scanner DS3608
EA3600 Ethernet Firmware v 001-R08
I am trying to collect barcode data from the scanner and move it to another tag that is a string. The issue is that the data will very occasionally come through as "$00$00$00....". I am wondering if this is a PLC issue, or potentially a configuration issue with the scanner.
How I am currently doing it
CPS: Source - Scanner.Data[0]; Dest - Scanner2.Data[0]; Length - Scanner.LEN
Both Source and Dest are SINTs. Source is Controller level, Dest is local.
The data is later moved again using the MOV instruction
MOV: Source - Scanner2; Dest - Scanner3 (a UDT)
