I am getting Device failure error intermittently on DeltaV ver 12 when trying to communicate with atlas compressors using MK5 (atlas compressor to gateway to convert CAM to Modbus RS485). We are using a serial card (s-series) and all the data seems to be mapped correctly. I can see the data on ModScan at the gateway (changing and looks good) and also plug in at the serial card and the values are good and changing. In diagnostics I am seeing the values coming in, but there is a device failure that keeps coming in and out. Anyone have any ideas?
