FA105640

Issue: Can you access the fault history in an ATS46 softstart using ModBus?
 
Product Line: ATS46
 
Environment: All
 
Cause: N/A
 
Resolution: from the Global Help desk;
``You can access by ModBus with W4090 (from 1 to 4) for the fault number, the value is in W4069 and W4091 is used by the ATS to Recall the fault.``

What I think this means is that if you put a value of 1 in word 4090, the most recent fault will be reported in W4091. If you put a 2 in 4090, you will read the next oldest fault in 4091. 4090 is used as a pointer, and 4091 is used to display the value that is pointed to.
