The OPC Server – Operating Recommendations and Limitations

There is no limit to the number of FieldServers that the OPC Server can communicate with.

The number of Clients is also unlimited. Note, however, that points memory usage is about 2k/point/Client e.g.20
Clients with 10000 tags each = 400MB. The Server creates a thread for each Client, thus by default each Client is
looping through 10000 tags every 25 ms looking for change of state.

It is possible to have remote Clients, but is not recommended for complexity/reliability reasons.  The FieldServers
are networked, so it makes sense to run the Server on the Client machine.  When running remotely the OPC Server
is  running  under  the  app  "dllhost.exe"  in  taskman.    Because  most  Clients  use  OPC  in  asynchronous  mode,  the
performance is almost indistinguishable for medium amounts of data.

The FieldServer limits the speed to about 50 poll blocks/sec (to test set poll rate to 0). e.g.. with 2 FieldServers the
total poll rate is ~100/s, if there are 10000 digitals in one Data Array on each FieldServer that translates to
2*50*10000 = 1 000 000 digitals per second.

Operating Mode - COM has 3 modes:- inprocess, local & remote. Local & remote have similar performance - the
overhead of each COM call is significantly slower than inprocess. The driver supports inprocess, and this mode is
recommended.
