Thanks a lot! @Mikhail
heavenbirdParticipantThank you for your reply. I used the driver of the opc da client to collect data from the opc server (kepserverex) and then published it to the mqtt broker through mqtt. But I want to reverse write data to Rapidscada through the mqtt client, in order to achieve data reverse writing to Kepserverex. I don’t know if it can be achieved?
heavenbirdParticipantAt present, I have solved this problem using NodeRED through the Rest API interface, and regularly perform GetCurData and SendCommand.
Thank you very much for creating such a great product. @MikhailheavenbirdParticipantFirst add communicator line and device for connect to your opc da server。
Then active OPC UA server Data source。heavenbirdParticipantheavenbirdParticipantThank you @Mikhail @tgkim79.
I have already used NodeRED’s http method to obtain data from RapidSCADA.
The access format is http://192.168.20.122/Api/Main/GetCurData?cnlNums=201-208.
But his use of numbers is not very intuitive, and I need to establish a correspondence between numbers and names.Can I obtain data using names? For example, how can I obtain the data of channel by using http://192.168.20.122/Api/Main/GetCurData?cnlNames=kep – _System._Time_Second?

heavenbirdParticipantI have meet the “E_NETWORK_ERROR” porblem both in the windows Server2019 and windows Server2008 R2。
I solved the problem in the following ways:
1、run dcomcnfg
2、if you can‘t find your opc server in 64bit system, try use “comexp.msc -32”
3、Select the Identity tab. chang to “The interactive user” -
