# system.iec61850.select

> Select an SBO type control to prepare it for a subsequent operate command for a configured IEC 61850 device.

This function is used in **Python Scripting**.

## Description
Select an SBO type control to prepare it for a subsequent [operate](system-iec61850-operate.md) command for a configured IEC 61850 device. These selections can be removed by using the [cancel](system-iec61850-cancel.md) function.

:::danger Select Function
The Select function is used to confirm a chosen access point before the Operate function will run. This is especially important for **Select Before Operate (SBO)** type controls. Misuse of this function can lead to unintended operations. Always ensure that the 'Check' parameter is properly set and understood before using this function, as it can influence the behavior of the **Control Interlock (CILO)** and **Synchrocheck (RSYN)** logical nodes in the **Intelligent Electronic Device (IED)**.

## Client Permission Restrictions
This scripting function has no [Client Permission](../../../ignition-modules/vision/vision-project-properties/vision-project-properties.md#vision-permissions-properties) restrictions.
