I have a Siemens PLC that operates as a data logger. When communication between the PLC and the Ignition SCADA system is lost, the following question arises: is it possible to send to Ignition the data stored on the SD card during the communication outage? The PLC used is a Siemens IOT2050.

Use this script function to add the data to the historian:

> **[system.historian.storeDataPoints | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.3/appendix/scripting-functions/system-historian/system-historian-storeDataPoints)**
>
> Store a list of data points to the specified historian.

It looks like this script function was just released to make the process easier:

> **[system.historian.types.dataPoint | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.3/appendix/scripting-functions/system-historian/types/system-historian-types-dataPoint)**
>
> Creates a data point that can be stored to a historian.

Not sure about the best way to move the data from the SD card to Ignition. Is it available in a .csv or .json file that can be retrieved by the gateway?

The process might look something like this:

1. Retrieve the file from the SD card (this process is going to be heavily dependent on a number of factors).
2. Create data points using system.historian.types.datapoint
3. Store the data points using system.historian.storeDataPoints
