Modbus RTU Master Config File
All of your configuration information is stored in an internal database each time you click the Save button on any page where configuration entries may be made. To make configuration portable from one device to another, and for purposes of retaining a backup copy, the configuration information may be exported and imported as XML or CSV files. This page is where your configuration file management takes place.
It is important to note that the XML file saved within any one client/server function will contain the configuration information for only that function. Depending on overall system configuration, a complete backup may involve more than one XML or CSV file.
XML Files: When an XML file has been selected, click the Load button to clear the configuration database and reload configuration from the given XML file.
Select an existing name to overwrite or enter a new file name, and then click Save to write the current configuration to the file in XML format.
You may type in a new name in the file name window for purposes of saving a new file. If you click the Refresh button, the file name will be restored to the name currently loaded into the client. The name could have been changed by selecting a file from the list below, or by typing in a new name. If the displayed name has not yet been used, then Refresh will restore the file name to what was most recently loaded.
CSV Files: If a CSV file is selected, the Load and Save buttons will change into load/save CSV buttons. When a CSV file has been selected, click the Load button to clear the configuration database and reload configuration from the given CSV file.
Select an existing name to overwrite or enter a new file name, and then click Save to write the current configuration to the file in CSV format.
The drop-down list will show a list of all configuration files currently found in the device's configuration folder. When you select an XML or CSV file from this list, the name will be copied to the Load/Save section of this page for pending load or save.
You may view the selected file by simply clicking View. You can delete the file by clicking Delete.
You may upload files to the IoTServer from your PC. Start by clicking Browse, and then use the browser's file dialog to locate the file on your PC. Once a file is selected on your PC, click the "Start upload" button to initiate the transfer.
You may also download files from the IoTServer to your PC. Click the Download button to transfer the selected file to your PC.
Any time an XML or CSV file is loaded, an error log file is generated. The error log file will be given the same name as the loaded file, but with ".err" as the suffix instead of ".xml" or ".csv". You may view the error log by selecting it from the list and clicking View.
Status is normally displayed in a message box at the top of the screen when the load or save operation is complete. But if you want to double check the status of the previous file operation, click Check Status.
The task (client or server) needs to be suspended while a file load operation is in progress to prevent acting on any partial configurations. This suspend/resume operation will normally happen automatically as part of the sequence invoked by the Load button when loading an XML file. The task must be explicitly suspended here for importing a CSV file. The Suspend button will become a Resume button when the task is suspended. Click Resume to continue operation. The current status is always displayed here.
