Many thanks to Crossbow ,Kaare_t & Inntele for their help. Visited Beijer site via http://forums.mrplc....h=1 & downloaded instruction sheets inc."downloading the project via Ethernet". Within 10 minitus I've managed to download & upload project from pc to hmi etc. without any problem & it iwas super fast (faster than USB). Therefore I would not bother with CAB-30 cable now. What a site "MR.PLC". Superb results instantly. Well done to you guys. donny
