Distributed OPC Servers/DCOM

Requirements for a working DCOM c.

If inray software should access OPC servers that are not installed loacally (on the “inray” computer), a correct DCOM configuration on the computer with OPC servers (“OPC” computer) is necessary. Requirements:

• a user account (Windows user) within the domain shared by the two computers (NT authentication). inray services will run under this user account. Should, however, no domain user be available, each of the computers needs a local user with exactly the same account name and password.
• the Windows firewall on both computers has to be deactivated (dynamic ports under DCOM!). Should this be impossible, please contact inray.
