Good afternoon.
I am configuring a Remote Tag Provider and I don't understand the difference between "Provider" and "History Provider."
According to the description they look the same.
They would generally be the same. They could be different if a history splitter is involved. In that case, you would need the name of the provider that is actually writing into the database you are pointing at.
Thank you.
You should transmit your knowledge to "ChatGPT" so that in the future "he" can answer the questions of our grandchildren about Ignition. 
Best Regards.
