Hello, Since I am facing something which look similar, I took liberty to explain my issue on this post.. Using LOGO ref6ED1 052-1MD08-0BA0 and HMI KPT400 6AV2 123-2DB03-0AX0 The Logo! I8 is connected to a 4-20mA input from an ultra-sonic sensor (powered with the LOGO! supply). This is used to regulate a motor speed depending on the product position. The HMI is used to select regul mode or not. I benched tested program and hardware. Every thing was working nicely. We then placed the equipment in the electrical cabinet on production and every time the ultra-sonic sensor is triggered, the network input which link the HMI and the Logo! change status randomly without any external action. We looked at possible EM interference but could not find anything. It is a bit puzzling as when we benched tested it we didn't ground anything and obviously now on production line all requirement have been followed...??? Thank you your help or suggestions. ------------------------------------------------------------------------------------------ |

Could it be that you have an overlap in the VM area? Could you upload the LOGO! program as a ZIP Archive? |
