Thnx.
Definitely, last card is dead (W1616T). After 14months, and without active inputs and outputs. Propertly suplied with 24VDC etc...
The door of box sometimes was open, and there is sometimes wet air, maybe it is reason for failure...
I tried remotely to detect problem. Pictures wasnt clear, I couldnt see that power lamp on that card wasnt green (see the picture).
It was strange, IO bus monitor status was 5, Connected Units Register was 7,7,10,255,255,...
Number of Connected Units was 3, and after reset changed to 0, but Connected Units Register was the same: 7,7,10,255...
I tried Configuration without that (4.) card (still connected), but without result.
After all, I went to factory and tried configuration without that card (I removed card) and it was ok. After that, I replaced the card.
Sorry for my bad english.
