Hi all,
I have an application where I want to log batch details to a file after each batch using a PanelView Plus 6. The PLC is a Compact Logix.
From my readings, it looks like the DataStore Plus ActiveX will be the best way to achieve this (although I'm open to any other ideas if people want to throw them out there), but there's just a couple of things I'm not completely sure of. Here's my plan as it stands:
1. Set up PVP with a display that's always active, but out of sight, with the ActiveX control on it. Ensure that this display is run at startup. Set Trigger connection to a PLC tag "Record_Batch_Details"
2. Batch completes. In the PLC, copy all batch data into a UDT and latch "Record_Batch_Details"
3. ActiveX sees the trigger tag go high, and logs the information in the UDT I just stored the data in
4. ActiveX turns off "Record_Batch_Details"
5.
So, a few questions:
1. How can I make the ActiveX (or really, just the PVP in general) unlatch the Trigger tag once it has finished logging the batch information?
2. Any tips on whether I should use a USB stick or SD card for the data logging? I think a USB stick would be more user friendly as far as the client being able to just plug it in to a PC and grab the log files, but an SD card less prone to it being, er, "borrowed". But beyond those sort of concerns, is there a reliability/speed/anything else factor to the decision?
3. What file path do I need to specify for the datalog to use a USB stick or SD card?
Thanks all!
