Problem with key control in Profilux Plus II

[smithpl]

Remote control shows the same what LCD :-) This is the problem.

Mathias, is it possible to add calibration option from PLC?

[Gunther]

This is the problem.

It shows what is needed for calibration, so please describe a little more where you see a problem.

[smithpl]

Gunther, please read posts in this topic.

On LCD and on remote control screen I see in second line www.ghl-kl.de
for that, I can't use remote control and LCD for ph problem calibration.

[Gunther]

Gunther, please read posts in this topic.

This is an individual fault of your PL, not a general problem. And in fact, no one knows if PLC calibration would work on your device. IMHO it would be to repair your PL instead.

this displayed message shows that there is something wrong with your serial number or the internal (secret) validation key (which is a protection against theft of intellectual property)

I guess the S/N or validation key went corrupt acidentally -> we have to recover them

please send an email to me, I can assist you to fix it

Hello, excuse me, did you decide your problem, because i have such trouble with my PL2. I disconnected the bus between monitor and sensor plate. The keys are not reacting, only beep, and www.ghl-kl.de on display. Thank you.

I'm still waiting for Matthias response :-(
