Adding ASCII text to Datalog

I have a project that requires an alphanumeric serial number to be included in the data that is logged. The serial number is scanned from a barcode and placed into a ST register on an AB ML1100. I discovered today that the C-More won't allow ASCII to be datalogged. Are there any suggestions to how I could include the barcode? I would hate to abandon the C-More's datalogging capabilities to move the datalogging back to the limited space of the ML1100. Thanks, Jim

If the serial number is actually numeric, you could move it to "N " registers and log it that way.

Response from Automation Direct Technical Support
You can data log ASCII data by using a Lookup Text object and then embed a tag into the message that is tied to your ST register. You can then select this message to be data logged to the message database. This file will be a separate log file than the line trend graph.

Adding ASCII text to Datalog
Jimbo,
The way I do this is through the alarm log. I add an alarm event that uses
the same trigger as my data logging trigger (that logs the numeric data).
One of the options for an Alarm event is to save the alarm file to USB. Since
the alarm event is generated by the same trigger as the one that triggers
logging the numeric data, the timestamp is essentially the same.
I am logging approximately 60 fields, using 15 Line Trend Graph objects.
After I ftp the results to a PC (I set up the C-More panel as an ftp server
so that I can push recipes to it as well) I process the raw results files,
including the alarm file and add a record for each trigger (in my case it is a
test record). The ASCII fields all come from the alarm file.
If you need more help, contact me.
