The steps are as follows:

1. Declare a connection in PcVue,

Go to General -> Data connections -> Add SQL connection

Select the data source “Built-in providers”,

Then select the data provider “. NET Framework Data Provider for REST”:

Finally, go to the second tab (Built-in) to configure the connection as below:

The LX CONNECT platform has two versions of APIs to retrieve data.

The v1 API allows you to:

• Retrieve list of all devices

• Retrieve information from a device

• Retrieve a device configuration

• Retrieve archives with Unix date format

The v2 API allows you to:

• Retrieve archives in ISO8601 date format

2. Create SQL Read query

• Retrieve equipment list

Select * from [get_v1/devices]

QUERYSTRING(“deviceType=LogUp“)

• Retrieve information from an equipment

Select * from [get_v1/devices/9fec58d9-c7a6-4e48-974d-77352f2345c9]

QUERYSTRING(“deviceType=LogUp”)

Note: 9fec58d9-c7a6-4e48-974d-77352f2345c9 = deviceUID retrieved from previous query result

• Retrieve configuration of an equipment

Select * from [get_v1/devices/9fec58d9-c7a6-4e48-974d-77352f2345c9/configuration]

QUERYSTRING(“deviceType=LogUp”)

• Retrieve telemetry archives of equipment in Unix timestamp format

Select * from [get_v1/devices/9fec58d9-c7a6-4e48-974d-77352f2345c9/telemetry/AI_1_SCALING_VALUE]

QUERYSTRING(“deviceType=LogUp&startTimestamp= 1733907061000000&endTimestamp= 1733907961000000“)

Note: AI_1_SCALING_VALUE is a «telemetryName» obtained from the result of the previous query on the configuration. The correct start and end date will be required.

PcVue tolerates a maximum of 5000 cells as a result of a read query with SQL connections. Please play on the time interval to stay in this constraint.

• Retrieve telemetry archives of an equipment in ISO8601 format (Remember this work with V2 of API)

Select * from [get_v2/devices/9fec58d9-c7a6-4e48-974d-77352f2345c9/telemetry/AI_1_SCALING_VALUE]

QUERYSTRING(“deviceType=LogUp&startDateTime=2024-12-23T08:51:00.000Z&endDateTime=2024-12-23T09:06:00.008Z“)

3. Retrieval of all archives from the LX CONNECT platform

The LX CONNECT platform only stores data from the last three months.

To retrieve all archive data from the platform, you can refer to KB1105 : Repeat Query for Sql variables.
