Charts on Touch are Blank when there is data to display

My Touch, purchased and installed about two weeks ago, has stopped displaying data on its charts.

It was displaying data previously but when checked last night it had stopped.

As can be seen in the following shots, there is data there to display.

Profilux model is 3.1N. Both Control Centre and the Profilux firmware were updated to the latest versions about 2 months ago. Touch firmware version is shown in pictures to be 1.05.

Please unassign the Touch from your PAB Devices, restart the device, and reassign it.

I will try that.

In the mean time I had got it working by deleting all saved readings and changing one of the chart axis settings (so not sure which of those actually made the difference).

It went OK for a couple of days then started to show rubbish readings (both value and date/time).

I am now using a longer USB cable between the PAB-Businterface and the Touch but both of these problems (no display and corrupted display) also occurred with the supplied USD cable so I don't think that is causing the problem.

The temperature and pH readings in the Profilux are fine so the reading issue is confined to the Touch.

Not sure that un-assigning the Touch was a complete success. I was able to un-assign it by unchecking the box and powering down the Touch. Navigating away and returning to the assignment screen would show the Touch to be gone however, after I turned the Touch back on, it would always auto re-assign and I would not have to check the box.

Also, even after un-assigning as described above it I could still see the Touch in the configure PAB devices screen, although selecting it returned me to the main screen. Even powering down both the Touch and the Profilux itself still produced the same results. This leads me to think that un-assigning does not actually purge any information so that any bad configuration data will simply be picked up again when the device it turned back on.

The charts were looking OK this morning so the jury is still out.

As a side note, even after un-assigning the Touch via the Profilux screens it remained in control center. Even shutting down and restarting control center after the Touch was un-assigned and while it still powered down left the Touch in control center - but navigating to it via the system screen did produce an error. It seems that once you create these device instances in your software there is no way to destruct them. This could do with a bit of tidying up.

If the problem persists, then you can perform a firmware update by going to "System", clicking on the "Touch" device, and clicking on "Firmware-Update". The latest firmware file for the touch device can be found on our website in the downloads section under PAB-device.
