Configuring jobs for the COPA-DATA zenon runtime

Requirements and considerations

  • All runtime data to be backed up must be available on the hard disk at the time of backup (e.g., Alarm/CEL values must be written from RAM to the hard disk, BATCH archives must be completed, etc.).
  • All files to be backed up must be located within the folder to be backed up.
  • Use the same folder structure on the SCADA/HMI PC and in the component folder: To make it easier to create a job for backing up the runtime files and to enable comparison, the folder structure in the component and on the target PC should match.
  • Adjust comparison and storage settings: If the component or the target folder of the job contains too many or other folders/files, you can adjust the comparison and save settings in the Job configuration accordingly (this allows you to exclude unwanted files or folders from comparison or saving).

Procedure

  1. Create a job with the Network (UNC) upload type.
  2. In the Username and Password fields under Network (UNC) settings, enter the credentials of the user who is accessing the network resources. The user must have the necessary access rights.
  3. In the Resource field, enter the computer name or IP address of the computer that you want to access via the network.
  4. To ensure that the the login to the computer is possible with the specified credentials, select the Check button. If the check is not successful, the job will also fail.

  5. If the data is stored in a subdirectory of the network resource, enter the path of the subdirectory in the Subdirectory field. Access to the subdirectory must be possible with the specified credentials.

  6. Under Advanced, you can reduce the network load caused by the job by increasing the value of the Sleep interval between data packets field and reducing the value for Maximum size of data packets.

    Higher values for the waiting time and lower values for the maximum packet size mean that the job execution takes more time.

  7. Select the Upload only when timestamp is different (reduces network load) checkbox to ensure that the timestamp instead of the content of the files is checked during the upload. This means that only new and edited files are uploaded for a backup. Files without changes are transferred from the previous backup, which further limits the network load.

  8. The Make offline project available to scripting interface checkbox enables upload scripts started by the job to access the latest checked-in version.
