For the moment I use a P3.1T computer and an expansion box 2 at home. I have noticed that I now and than get an alarm from the digital temp probe. I have seen this before (and still see) with this combination and alarms - at one of my jobs we have two systems with this combination and get temp alarms and PABCOM alarms rather often.
My alarm looks like this
pH-value 1 : 8.01pH
TEMPERATURE 2 : ***
REDOX 1 : -22mV
Temperature 3 : ***
pH-value 2 : 8.34pH
Redox 2 : -22mV
Conduct.(S) 1 : 32.6
Redox 3 : 408mV
Alarm 000: Alarm: Temp 2 virt värme
Alarm 001: Alarm: Temp 3 temp sump fläkt
Temp 2 is a virtual copy of temp 3
Graph could look like this

However - I have only seen this with this type of configuration -> p3.x + expbox 2 + digital temp probe. When I run P4 with digital temp probe at home before - not any problem. When I run P3.x + expbox 1 (the old one) + expansion card digital temp + digital temp probe - at another of my jobs - no problem either
There is a lot of electrical devices around all of these installations but - it seem that it only happen when Expansion Box 2 is involved together with P 3.x. I have not test with P4 + expansion box 2
Any suggestions?
Sincerely Lasse
