The FBGS interface can be used to measure data from sensors, which are based on the FBG measuring principle and connected via a so called interrogator measuring device.

The abbreviation FBG means Fibre Bragg Gratings, a special opto-electronic measuring method with optical fibers by FBGS Technologies.

Out of the different applications which are possible with this measuring method ibaPDA supports only temperature sensing.

There are measuring devices (interrogators) available for 4, 8 and 15 channels. One channel corresponds to one optical fiber.

ibaPDA only supports interrogators with an Ethernet interface, such as

  • FBG-scan 80x-EP

  • FBG-scan 90x-EP

(x = 4, 8, 15)

Interface settings

Set all values to zero when the connection to an interrogator is lost.

If enabled, all measured values of the drive are set to zero as soon as the connection is lost. If this option is disabled, ibaPDA will keep the last valid measured value at the time the connection was lost in the memory.

Start the measurement even if an interrogator is not accessible

If this option is enabled, the acquisition will start even if an interrogator is not accessible. Instead of an error, a warning is prompted in the validation dialog. If the system has been started without a connection to an interrogator, ibaPDA will try to connect to the interrogator at regular intervals. If the connection attempt is successful, ibaPDA starts the acquisition of the data from the interrogator in question without restarting the general data acquisition.

<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.

Connection table

For each connection, the table shows the connection status, the current values for the update time (actual value, average, min. and max.) as well as the data size. In addition, there is an error counter for the individual connections during the acquisition.

In addition, there is a column for the counter of the number of data sets (“spectra”) received from the FBGS-interrogator. One data set is a collection of peak wavelength and intensity pairs of all configured sensors of all configured channels (fibers) of the interrogator.
Available modules

Product name

ibaPDA-Interface-FBGS (Art. no. 31.001017)

One interrogator can be connected per interface license. Up to 64 licenses for a total of up to 64 devices can be activated. Regarding devices with 15 channels, this leads to a total of up to 960 channels. Each channel can contain one or more sensors.
