For access of the OPC server to individual objects of the D2000 System, it is necessary to create a user in the D2000 System. The OPC server will log on to the system as the user with defined access rights. The user name must be in the form of OPC_User_<opc_server_name>. The user should have access rights to D2000 System objects that will be available to the OPC client.
Note: In version D2000 21.1.72, the Int type was changed from 32 to 64 bits, which results in the representation of Int/Ci/Co values as Int64 (formerly Int32). Therefore, new start parameters were supported, which can be used to change the behavior of the D2000 OPC Server as follows:
- --INT32INV values of type Int/Ci/Co will be represented as Int32 in D2000 OPC server, values outside the range of Int32 will be invalidated
- --INT32SAT values of type Int/Ci/Co will be represented as Int32 in D2000 OPC server, values outside the range Int32 will be saturated
