The interface IEC 61850 client has the following functions and configuration possibilities:

Set values of all signals without external timestamps to zero when the connection to a device is lost

If this option is enabled, all measured values of a device without external timestamp are set to zero as soon as the connection is lost. If this option is disabled, ibaPDA will keep last valid measured value in the memory at the time the connection was lost.

Start acquisition even if a device is not accessible

If this option is enabled, the acquisition will start even if the device is not accessible. Instead of an error, a warning is indicated in the validation dialog. If the system has been started without a connection to the device, ibaPDA will periodically try to connect to the device.

Allow inaccessible attributes

Enable this option to start the acquisition, even if no attributes are accessible. The inaccessible symbols are issued as warnings in the validation dialog. This can only occur if the address book is not up-to-date!

If you do not enable this option, then the measurement will not start in the presence of inaccessible symbols.

IEC61850-7-2 files destination path

Enter here the path to the destination directory if you want to use the File module in order to transfer COMTRADE files from an IEC 61850 device. This directory will be the base directory to store the files. The path should be given from the ibaPDA server's point of view. A UNC-path is permitted. In order to access network shares add user name and password. Use the <Test path> button to check ibaPDA's ability to access the path.

Connection table

The table shows different diagnostic values of the individual connections during data measurement. To reset the calculated times and error counters to zero, simply click on the <Reset counters> button. All modules of an IEC 61850 device use the same connection.

The telegram counter is a continuous counter that is incremented by one with each received telegram.

The update time is only shown for modules that automatically query data from the IEC server with the set update time. This is only the case with MMS modules without report control blocks. The currently measured update time indicates whether the desired set update time is reached. In the case of overload of the IEC server, the desired update time cannot be reached. The corresponding line in the connection table is then colored in yellow.

For MMS modules without a report control block, the response time describes the time that passes between the data query by ibaPDA and the receipt of the response.

For all other module types, the IEC server automatically sends data according to different criteria. In this case, the response time describes the duration between two received telegrams.

<Open log file> button

If connections to IEC 61850 devices have been established, then all connection specific actions are recorded in a text file. With this button, you can open and have a look at this file. In the file system on the hard drive, you will find the log files of this interface in the path ...\ProgramData\iba\ibaPDA\Log\. The file name of the current log file is Iec61850Log.txt, the name of the archived log files is Iec61850Log_yyyy_mm_dd_hh_mm_ss.txt.
