The Data Acquisition Service

The Data Acquisition service is responsible for the replication of the raw data

from the RTUs and/or other addUPI servers into your system.

Figure 57 illustrates a general addVANTAGE Pro 6.4 installation from the data

acquisition perspective.

The wireless network shown in Figure 57 has a Telemetry Gateway that acts as

the network master. The gateway has an internal storage unit that keeps the

incoming data from the RTUs for a certain amount of time. Server A (also called

primary because it connects directly to the data source) periodically connects to

the gateway via TCP/IP and retrieves the data. This function on the server is

controlled by the Data Acquisition Service.

In this scenario, the Telemetry Gateway is a data provider (in fact, it is a server

from this point of view) and server A is a data consumer (a client from this point

of view). It is important to understand that the terms client and server have

different meanings depending on the context. From the Data Acquisition Service

perspective, the meanings are different from what we defined in this book as

client and server. To avoid further confusion, we didn’t show an addVANTAGE

client (the browser) in Figure 57. In fact, in this context, the addVANTAGE client

is irrelevant.

A data consumer can also be a data provider, as shown by the connection

between server A and server B. When server A acts as the server and server B is

the client, the data from server A will be replicated to server B.

Note: Only tag data can be transferred between servers and gateways at this level

(not events).

Configuring the Data Acquisition Service

Before you begin, you must know the IP address or the name of a remote server

you want to connect to. As already stated in this manual, it can be either a

Telemetry Gateway, another addVANTAGE Pro server, or in general an addUPI

server. You will also need an account and a password on the data source.

Note: addUPI is an http-based protocol used to transfer raw data between Adcon

telemetry components. You can get the protocol specification from Adcon

Telemetry free of charge.

Complete the following steps to add a data source to the Data Acquisition

Service:

1. Select Tools
