The interface provides the following functions and configuration options:

Set all values to zero when the connection to a Modbus server is lost

If this option is disabled, the last valid measured values will be kept.

Start acquisition even if a Modbus server is not accessible

Generally, the data acquisition cannot be started when the Modbus server is not accessible. If this option is enabled, the acquisition will be started with a warning message. In case the connection to the Modbus server is established only thereafter, the configured values will be measured without having to restart ibaPDA. This option is recommended for an automatic restart.

<Open log file>

If connections to controllers have been established, all connection specific actions are recorded in a text file. Using this button, you can open and check this file. In the file system on the hard disk, you find the log files of this interface in the path …\ProgramData\iba\ibaPDA\Log. The file name of the current log file is InterfaceLog.txt; the name of the archived log files is InterfaceLog_yyyy_mm_dd_hh_mm_ss.txt.
