If you are using communication directly to the IEC61850 Connect Server, you can have up to 80 IEDs per OPC instances, 4 instances per server, which leads to 320 per server computer.
If you are using AC800M controller with CI868 board, the IED limit per board is 80 (via GOOSE) and 20 (via MMS).
Your system will definitely work.
