Hallo.

Can somebody help me?

I have connected LOGO 8 and Simatic HMI KTP 700 basic.

I used Tia portal 13 to program KPT 700 basic.

LOGO 8 programed to measure outside temperature from– 20 C to + 30 C. works on LOGO display.

If the temperature goes to minus degree can KPT 700 not show the temperature?

If the temperature goes to plus. C it works again.

Can KTP 700 Basic not show negative numbers??

I have programmed BAR in KPT 700 to -20 to +30 without problems.

Used tags Wordvw xxin KTP 700 andWord xxin LOGO 8.

I look forward to hire form you.

Ove Brandt.

I will try coming back later.
