There exists next scenarios:
1. If there is OPC server on "opposite" side - client
2. If there is OPC client on "opposite" side than OPC server
3. If there is OPC server on both sides there will be necessary OPC server + 3rd party solution for OPC data mirroring
Regarding OPC server functionality and available licences clarification:
DA - data access (on-line data available via OPC)
HDA - historical data access (historian available via OPC)
AE - alarms and events (available via OPC)
RO - read only - you can read only data from OPC server
RW - read / write - you can read and write data to OPC server
OPC Client - support both functionalities (read / write), but possibility itself is given by OPC server configuration (whether is accessed for read only or also write).
