Hello Sao; Vipa SLIO units work very differently than Siemens PLCs. You should start by looking at VIPA documentation, such as this one: http://www.vipa.dk/uploads/tx_sbdownloader/HB300E_IM_053-1EC00_11-03.pdf The appearance of MF LEDs appear to be linked with power distribution for the modules on the SLIO IM rack, as can be seen from this extract from the manual above (see screenshot, But there is no example of a case where every module shows MF. So you should try to reach VIPA support on this. You could try to open your CPU's diagnostic buffer, if there is an active SF or BF LED on the cPU then some fault information should be logged in the buffer and might help. I am not sure however of the messaging capacity between a SLIO rack and a S7 CPU... Hope this helps, Daniel Chartier |
