# system.iec61850.cancel

> Cancels the selection of an SBO type control on a configured IEC 61850 device to prevent the operate command from performing.

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

## Description
Cancels the selection of an SBO type control on a configured IEC 61850 device to prevent the [operate](system-iec61850-operate.md) command from performing.

:::caution Cancel Function
The Cancel function will clear a selection of a **Select Before Operate (SBO)** type control if an operate command is not desired to be executed on the selected control. This function can be used as a safety measure to prevent 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)**.

String| `deviceName` | The name of the configured IEC 61850 device.
PyDictionary| `mapParams` | Control parameters dictionary that requires the following keys to be specified: name, T, orCat, orIdent, Check, and Test.

mapParams = {'name': u'SSSA_52AFA_FPRCTRL/CBCSWI1.Mod', 'T':1 'orCat': 0, 'orIdent': u'not-supported', 'Check': 0, 'Test': False}
system.iec61850.select("IEC61850", mapParams, 1)
 
# after the select function was applied, cancel if not needed.
system.iec61850.cancel("IEC61850", mapParams)
