Hello!

I am using the adapter COMTRADE, but it seems like the inputs are not being recognized… is there something wrong in my configuration? I selected the inputs I want and my Connection String looks like this:

DeviceID=1; FramesPerSecond=60; StationName=comtrade; InputMeasurementKeys={d4d51e13-4934-4b38-b030-1ea5a87fcc55;31644eab-ffd3-49c5-b1cd-2e72ae3ca106;be635a14-f1de-49ab-951a-3c2b333f22e2;3dbbcc0d-4729-4183-b115-46cf28ab5d8e;ffea09dc-1bdd-4d4e-9591-90c1e28eda16;8b169e4a-1ce8-4e61-a693-9a127dba3788;7b5507e1-1f66-430e-a2ca-abbbe09af199;81472264-4124-45d7-8651-d9a35bfc2c8a}

I am also using CSV\_EXPORT and it works fine.

Thank You,  
Letícia.

Hello Letícia,

I believe this adapter requires the `LagTime` and `LeadTime` parameters to be configured. It’s a bit hard to tell from your screenshots, but it looks like maybe they are not configured.

FYI, if you initialize the adapter while the openHistorian Console is running, you may see an error message. This is a pretty useful troubleshooting step in general.

Thanks,  
Stephen

Stephen,

It seems like it worked now, thank you!!  
Where do these archives are being stored? I wasn’t able to find them.

Thank You,  
Leticia.

To be honest, I looked into it, and it appears that this adapter doesn’t actually do anything. You won’t be able to get data in COMTRADE format like this. Instead, I recommend using the `Trend / Export` page on the openHistorian Web Interface.

Thanks,  
Stephen

Stephen,

Okay, thank you!
