Hello,
This isn't a flow question as much as it is a DeltaV (version 10) module/interface issue. This issue has just started cropping up and doesn't appear to be isolated to flow transmitters, as I have seen this same error on a pressure transmitter.
When I open a Faceplate on as flow data link (R505_FI-07) I get the following pop-up message on the user graphic:
Error Number: 570621953(22030001)
R505_FI_07/AI1/HI_LIM.F_CVPCT(OUT_SCALE): Bad value - Conversion Error.
Digging deeper, I notice in the R505_FI_07 control module that the HI_LIM online value is 1.#INF. I've searched this and google turns up references for infinity, which is "printed" when integers are divided by zero (how could I forget this from my C++ programming days!). This LIMIT value which is programmed into the parameter offline then viewed in the online value doesn't undergo any any division by zero that I'm aware of.....Also I noticed that when I look in the parameter view window of the control module, and click on the parameter properties, it asked for a float value which I believe is the correct data type for the alarm limit. If I take the module offline, the parameter value is the correct value and is of the correct float format. This appears to be an issue with the online environment and I am wondering how to rectify this issue without having to perform any changes or remapping AI blocks etc.
Has anyone here had a similar experience or know how to identify and correct the issue?
Thanks
