Hi Robin,
I've moved this to the "Proficloud" topic, I hope that's OK.
If I understand correctly, you want to log data to the Proficloud TSD service, from either this PLC and/or other PLC(s). Then, you want to read back some data that is logged in the Proficloud database, using a client running on the PLC, using the REST interface on the Proficloud TSD database. Is that a fair summary?
I understand that it is possible for the Proficloud team to set up REST access to a customer's Proficloud database, on request. I guess you have requested this already.
Since the REST interface is enabled on a case-by-case basis, and is not a generally available feature, I will ask someone from the Proficloud team to contact you directly with information on how to use that REST interface.
Regards,
Martin.
