I have running devicenet network consist of 1796-SDN and 12 powerfexs 40 .
the problem is during the line operation F71 occurs occasionally on Powerflex screen NOT on the scanner .
And this not fixed for just one drive it is appears on all of them but not in same time .
I replaced the powerflexs , replaced the resistance , replaced the cabling but without hope .
The only solution i didn't go through is 1796-SDN replacement .
Are there any one help on replacement procedures ?
Could you please anyone help on this ???
