Modify wait time of MultiDownload/Online Change

Depending on the network infrastructure the MultiOnlineChange (MOC) might run into errors due to timeouts. The user will not be informed about these timeouts directly, but each timeout might result in errors.

Examples:

“Logfile cannot be read” (red line in PLC list even though the download/change was successful).

“Online Change not possible” (PLC changes state from “run” to “stop” during Online Change, because the wait time for loading the project was not sufficient).

To avoid these timeouts and the resulting errors the user can extend the wait times of the MultiOnlineChange plug-in/tool. These times can be adapted in the template XML file “CmdTemplate.xml” by increasing the values in the delay lines. The file has the following content:

Each delay defines a wait time in milliseconds, which can be adapted by the user. As an example some of the delays are emphasized above:

• The three emphasized delay times in tag <DownloadPLC> can be increased to ensure that the MOC waits long enough for the log-file to be accessible after reboot before reading it.
• The four emphasized delay times in tag <OnlineChangePLC> can be increased to ensure that MOC waits long enough for loading the project, logging in to PLC and reading the log-file.
