Dear, I use LOGO 8 6ED1052-1FB00-0BA8, with 2 pcs of expansion modules 6ED1055-1FB10-0BA2 and one RTD module 6ED1055-1MD00-0BA2. In program I use AI1 and no analogue inputs on LOGO. I downloaded from yours web pages http://w3.siemens.com/mcms/programmable-logic-controller/en/logic-module-logo/application-examples/pages/default.aspx application Wire break/short circuit evaluation for Pt100/Pt1000 sensors. When I connect 3-wire pt100 I have correct values on LOGO. The problem is when there is NO connection (break) on display is written schort circuit instead wire break. Can you help to troubleshot why is this happening? Thanks
