¶ General Description
This function restores a user parameter from the device's memory. The restoration occurs from the last telemetry record of the device.
To ensure the recorded value is stored in the device memory and can be sent to the monitoring server, the user parameter must be configured in the protocol settings:

The read result: True - Value successfully read from device memory False - Value not found in memory |
Function logic depends on the data type:
➜ If the
valueinput is connected to a variable of type Float, the function writes data to the buffer using the IEEE754 standard. This approach is necessary for values transmitted in Float format (e.g., 12.6).➜ Otherwise, the function writes the data as Int32.
Conversion is automatically performed using hidden functions FROM_FLOAT and TO_FLOAT.
