Found In Egroup: Automation Control \ view thread
Hi Ed, That makes sense now. Reading the Echo documentation (Getting Results) I understood that Echo V2 could be used with firmware versions 33, 34, and 35, but apparently that is not the case. Thanks for clarifying. I changed my controller to firmware to V35 and all is working fine now. Regards, ...

EDIT: corrected a typo and reposted the image for better vieweing. -FL Thank you Edward. I prefer not to have a flag that has to be manually changed to enable/disable simulation.

Thank you Edward. Sorry I may have not phrased my question clearly. I am aware of how to read/write tags from Echo via API (in fact that is what I have been working on as of late). My question is about modifying System Values (SV as opposed to tags) via Echo API. Any ideas? Regards, ...

Thanks Ed. You are right, that (a loop using RegisterTag) is what I am doing at the moment, and it works fine. Is there a new API version coming? and if so, when? Thanks Ed. Regards, Jhon

Hi, Is there a function in the Echo API to register multiple tags in a single call?

Hi Michal, Thank you for your response. As an exercise, I tried to read an individual structure member as you suggested. A call to RegisterTag("MyTag.Inp_Running") returns a valid handle (> 0). However when I try to read the tag information using GetTagInfo(), I get a "Tag Not Found" error. In the ...

I have ...

Hi Ronald, I have had similar issues using the SDK. They went away once I started running Studio 5000, Visual Studio and Echo db in Admin mode. Give it a go see if it helps. Cheers, Jhon

Hi Mark, I am implementing an interface for Echo in ProcXim, and found it is great but having a few issues with reading certain data types from it. Have searched a lot but found little. Could you point me to a forum / email that I can submit technical questions to? Thanks. Jhon
