Set up Windows security to allow data logging to a remote computer

If the data logger process is logging to a mapped network drive, a network share, or an ODBC database that is not located on the same computer as the HMI server, you may have to change the Windows security settings for the Datalog Server (
DatalogServ.exe
) and the Rockwell DataLog Read Server (
DlgRdServ.exe
).
TIP:
  • If the data logger process is to log to a shared folder on a remote computer, you do not have to change the DCOM settings. But the account under which the data logger is running must have read and write permissions to the folder.
  • When logging to a remote database server that uses a UNC format pathname or is network shareable such as a Microsoft SQL Server (fully tested), Microsoft Access, or Oracle, you can select either
    The interactive user
     or
    This user
    .
  • The account selected for This user should be a logon account that uses a password that never changes; otherwise this DCOM setting will need to be manually changed whenever the password is changed.
  • If The Interactive User setting is used, a valid network user must be logged on at the HMI server.
  • Another way to implement data logging to a remote, shared folder, is to set up the two processes, DatalogServ.exe and DlgRdServ.exe to run as services.
