Error Proofing
Barcode Reader
The max length of a barcode is 20 characters if it is longer the leading characters will be lost and the last
20 will be used. Since barcode readers send their characters in burst there is no need to program in a
length. The software just waits for the reader to stop sending. Once the barcode is read the results are
stored as the VIN.
Barcode Options
When a good barcode is received it can optionally reset the batch and/or enable the tool. A good bar-
code is determined by the VIN Pattern Matching option. If the barcode matches one of the parameter
sets VIN matching patterns it will be considered a good read.
Reset Batch on Good Barcode scan
If enabled, controller will reset the batch count on a good barcode scan.
Enable Tool on Good Barcode scan
If enabled, controller will enable the tool on a good barcode scan.
VIN Pattern Matching
All new VINs from barcode readers, Profibus, DeviceNET, Ethernet/IP or protocols are checked against
for a VIN match against each PSET (starting from #1 and through #8). If a match is found the PSET is
changed. In order to qualify as a match the received barcode must be at least as long as the match
string. The match string can contain
“ don ’ t care ” characters (‘.’) as a wild card. In the example below a
barcode of “ Abc123 ” selects PSET #1, “ abc567 ” selects PSET #2, “ def ” selects PSET #4, “ ABc ” selects
PSET #5, and “ AB ” does nothing.
