DI810 and DO810: warning on most channels. Screenshot attached. Thanks!!
I am using AC900F and CBF 2016. I recently added a DI810 and a DO810 to an existing project. They share the CI801 with some AI845 bu have their own power supply. Total IO modules on the CI801=7.
I am getting an amber warning light on the module itself and in CBF it shows as the screenshot indicates. DO is error on the second 8 channels, DI is error on all channels.
I am not sure where to look, as google was not very helpful about troubleshooting this.
I am willing to provide more informaiton, if you could tell me where to look!

Do you have voltage supervison enabled?
It seems to me that You do and that the process voltage for these groups failed (or at least it's seen as such by the module). My guess is based on the fact, that Your DO810 module shows errors in 2nd group (channels 9-16) and these are channel errors.
What kind of MTU (module termination unit) do You use?
If Your supply is ok and its connection to both L1 and L2 inputs on the MTU are ok, then the voltage supervision error may be caused by blown fuse on the MTU.
You may check both of these suggestions by making simple tests with Your power supply.
Hope this helps,
