Accessing Historical Alarms and Events Over OPC A&E Server using Python / .NET / Java or any other platform

[rajnishnationfirst]

Hi ,

I am implementing and want to capture Historical Alarms and Events over OPC A&E Server ( Not OPC UA or OPC HDA ) created in Siemens WinCC SCADA.

I tried HDA data over OPC UA and implemented in Python Free OPCUA SDK and working fine. But the WinCC does not support the capturing Historical Alarms over OPC UA and yet the OPC UA has node.read_events_history(start_time,end_time ,0) , but i cannot use this function on OPCA&E server available in python .

The below is the snap of WinCC Siemens SCADA OPC A&E Server and don't have node Ids and Tags configuration.

Could any one help with some open source SDK's available in Python , .NET or Java or Java Script for OPC A&E Server capturing historical alarms and events. ?

Thanks and Regards

the problem with you question is that this repository is only for "OPC Unified Architecture", "OPC A&E" is part of the older "OPC Classic" (COM/DCOM) based standard!

i dont understand the question! this is OPC UA not OPC A&E (completly different transport protocols), you should search for such COM/DCOM libs in python but as far as i know its bound to windows and is kind of insecure. there are gatewaysolutions out there (Kepware, Prosys, ...) which can be used to get the data, but this is up to you!

There are products like this to bridge classic OPC and OPC UA: https://prosysopc.com/products/opc-ua-gateway/

Check this out, you can use Python/JavaScript/C#/Java etc. to access Classic OPC DA/HDA/AE servers. Cheers!
