Hi,

i don't know if i'm misinformed but as i could read around the web and on the siemens documentation you should be able to use more than one istance of MB_CLIENT when each has different DataBlock, IP address and slave ID. When i do so it gets to work only the first MB_CLIENT wich is highlighted but the second one is not wich is weird because it's powered too.

I've also attached some screenshot to make it more clear

Any suggestion would be grateful :)
