Hi Ansul, Interesting question You are not first one with this issue, but your question is little different. /tf/WW/en/Posts/49205 I think according data sheets this backplane bus need max 10mA but not tell is it per channel or what? Power loss (data sheet)of the modul is near 3.5W. P=U x I and that P=3.5W and U=5V gives all current near 0.7A so it´s 700mA. If each channel take 10mA it´s only 160mA there is 14 pin!.So someone have more electrical information? Why there is 14 pins in connector. Hard to find out any data is it some secret? So it would be interesting to get more information about backplane bus. Regards Heksu 6ES7 390-0AA00-0AA0 S7-300 Bus Connector (PC-GF20) "The S7-300 backplane bus is a serial data bus the modules use to communicatewith each other and from which they draw the power they require. The connectionbetween the modules is implemented via bus connectors."/tf/WW/en/Posts/4423 |
