I need some clarification over the some functionalities used in openHistorian. There are some doubts i have which i want to clear.
What is Data Publisher?? and how it works ??
When i have Configured Subscription to Internal Gateway Publisher, then what i am configuring is a Data Publisher Configuration or a Subscriber Configuration?? As in Sample Test code of Data Publisher and Data Subscriber what i have understood that from Data Publisher You transmit Data and from Data Subscriber connect to Same channel and you receives the Data.
So my query is if i am configuring Internal Subscription to Internal Gateway Publisher it was saved into Device table. So it treat this configuration as Device which is communicating on GEP and through which we can received the Data but where is my Subscriber.
Also need some explanation and significance of All the fields are used in Manage Device Configuration
for better understanding.
… What is Concentrator whether we need to configure it as a Concentrator??
Or Subscriber is a different functionality which is used to fetched the Data from openHistorian Server.???Then can you brief about how Subscriber works??
3.) While configuring Subscription to Internal Gateway Publisher it is what are the use of option
Receive Internal Metadata and Receive External Metadata. As i had checked both option?? So if i got some clarity then i can configure it properly.
4.) While configuring Measurement for can i have brief explanation of all fields specially Adder, Multiplier, options Internal and Subscribed and Measurement Type.
For my sample application I have created Measurements with Check option Internal, Subscribed and enabled. Own Point Tag, Signal Reference and Measurement Type = Statistics.
Measurement Type has multiple Values. So what is the significance of Measurement Type for the Measurements for which data come from another application. Whether it is used while storing Data?? Need to understand Measurement Type.
I know there are many queries ?? But if i have clarity on these stuff then i can build proper application
Thanks in Advance
