Hi there,

We have Ignition 8.1. We will be replicating and would like to use same Database and Ignition server for another site in different time zone.

Do we need to purchase a site license? if so, how much would it cost?

Ignition is licensed per **server** , not per **site**.

Technically, yes.

In practice, it depends. PLCs need to be polled locally, for example, and there are other performance concerns anywhere network latency is sensitive.

You should at very least have the OPC UA modules if you are polling PLCs, on a per-site basis.
