Node Configuration
The recommended node to run the Remote Access Server service differs depending
on the size of the system. See section
Recommended Hardware Configurations on
page 23. Select the desired node from the drop-down menu.
Read-only System
If the
Read-only connection
check box is selected all clients connected to this
provider can only read the values. This means that OPC writes from faceplates,
history data updates and alarm acknowledge will be prohibited for all connected
clients.
Read-only connection is a good choice if the system is to be supervised only, and it
should not be possible to control anything from a remote client.
User Mapping
There are two ways to configure the users depending if the users in the subscriber
and the provider systems belong to the same Windows domain or not.
If the users in the subscriber system and provider system belong to the same
Windows domain the
Common Windows domain
check box should be selected.
If the Remote Access Server and Client are in different Windows domains a user
mapping between a user in the subscriber system (Remote Access Client) and a user
in the provider system (Remote Access Server) must be set up. This is done by
clicking the
Add
button.
Input the Windows account name, including the domain, for the subscriber system
and select a Windows account to map to on the provider system.
If the remote user is a node local user, i.e. not a domain user, on the subscriber node
the Remote Access Client node name must be inserted before the user account. For
example: the local user Operator with the Remote Access Client running on node
N124 should be written as “N124\Operator” in the user mapping for the Remote
Access Server.
Usage of “Common Windows Domains” requires the user in the subscriber
system to also exist in the provider system.
