You need to create the EXACT SAME user account names AND passwords on BOTH

machines. This does not mean that you must be logged in as the same user on both

machines to get the system to work, just that the same user/password combination

must be defined on each machine.

See the following general guidelines:

 For a distributed configuration, the OPC Server and Clients must be part of the

same workgroup or domain.

 On a workgroup network all users who will have access to the OPC server must

belong to this workgroup.

 On a workgroup network, an account with the same username/password

combination must be created on the server and client stations.

 If necessary, adjust DCOM settings: instructions for the DCOM settings are given

in the next section.

Note: If there is a loss of communication between the MK8000 OPC Server and one of

the client stations, it will not be reported by the MK8000 to the other clients.

6.4 Possible difficulties in integrating an OPC client

6.4.1 Exporting data to a 3rd party OPC client

This section addresses problems you may have when exporting data to a 3

party

OPC client, and provides solutions to those problems.

Exported data columns are not separated properly

Different regions in the world use different symbols to represent the point where lists of

data are separated. In the US this is typically a comma, while in Europe it is typically a

semicolon. When the data is exported, the list separator must match the list separator

in the Windows Operating System where the data is to be imported.

1. Check which list separator is being used:

You can check which list separator is being used through the Numbers tab of the

Regional Settings window.

(Start > Control Panel > Regional Settings > Numbers tab)

2. Find and replace the separator in the export file:

separator with the correct one.
