DSDO modules failing intermittently - S100 IO with AC800M

Hi,

I would like to know if there is a known issue/product bulletin related to this issue experienced on site. A PM891 controller is connected to S100 IO via a CI856S module. Only the DO cards fail. System 800xA v5.1 is being used. I have attached screenshots of the firmware version of the controller and CI modules, and the system software version.

Could this be a firmware issue?

There are a bulletin available for a certain batch of HW which describes an issue where the while CI856 stall. What you describe is not a known problem. The CI856 firmware used shall be OK. You dont tell the age and serial number of your CI856 and the DI boards? And how does the S100 Physical bus look like ? cable length? Optical modems involved or not? etc etc. How old is the installation ? Has it been working before or is it a new comissioning?
