ION8650 integrated using IEC-61850, cVal.mag values are in Bad quality and without time stamp

[Pepz]

I am integrating ION8650C Power meters to 800xA System DCS using IEC-61850 protocol, I can read almost all the data, but I have problems with all data ending in "cVal.mag" (currents, voltages), becasue when the values of this data change, the changes are automatically displayed but with Bad quality and without time stamp.

Power meter model: M8650C7C0H6E1A0A

File used: SE_ION_8650-C-F01_E2V01.icd

I attached screenshots.

Hi @Pepz 

Please make sure the dataset includes the Data Attribute Level e.g., cVal.mag, q, t and not just Data Object Level e.g., PhV, A, PPV.

In IEC 61850:

Logical Node: e.g., MMXU1
Data Object: e.g., PhV, A, PPV
Data Attribute: e.g., cVal.mag, q, t

If your dataset only includes the Data Object (like PhV or A) without specifying the Data Attribute (like cVal.mag, q and t), the client may not receive the actual measurement values, timestamps, or quality indicators.

You can also use some IED Explorer or IEDScout Tools to confirm whether the issue is with the meter or the 800xA client.

Hi Mehran,

Thanks for your response.

Initially, I used the total Datasets and RCBs generated for default, without changing anything on the map. The result was that I obtained values that changed automatically but with Bad quality and no timestamp. This only happens with data with values per phase (currents, voltages,...). If I update manually (polling) I can read perfectly: good values, good quality and timestamp, the problem is the automatic update.

Now, I have tried modifying the "MMXU" Dataset to include the Data Attribute Level, but this time I can't see any values. 

In both situations I can see the values with IEC Explorer, with good quality and timestamp. 

I would appreciate it if you could show me an example of "MMXU" Dataset of an ION8650 integrated by IEC61850 from any application you have done before.

Hi @Pepz 

You're welcome. 

If manual polling retrieves correct values with good quality and timestamp but automatic updates shows bad quality and no timestamp using default datasets and RCBs, then likely it is due to how the Report Control Blocks (RCBs) and Datasets are configured in the CID file and how they are parsed in 800xA System client.

I usually generates the CID file using CET850 and test the result using IED Explorer. What I would suggest is, checking RCB Settings and ensure the RCB has: TrgOps with dchg=true, qchg=true, period=true,

OptFields with timeStamp=true, reasonCode=true, seqNum=true

CET850:

editing CID file:

IED Explorer shows correct data, therefore the dataset works in IED Explorer, client 800xA still shows bad quality and no timestamp, please verify if its IEC 61850 parser supports DA-level references.

Hi Mehran,

I have used the default values for the RCB parameters, which are the same as those are you suggest.

It seems that the problem is on the 800xA system side, I have requested assistance.

I will let you know if I manage to solve it.

Thank you

Hello @Pepz ,

If using a report subscription, the ION8650 meter does not send a timestamp attribute for each measurement, the timestamp of the report is the timestamp for all measurements in the report.
