# get setting

This block is part of the [`system settings`](https://docs.rual.nl/block-types/system%20settings) group and was last modified in core [`v9.2.15`](https://docs.rual.nl/core-versions/90215).

get a created system setting

- value `value`

Reads the system setting selected in the block's configuration (fixed key, no input pins) and outputs its stored value. Outputs nil when the key does not exist or the lookup fails; when no key is configured NO output is written at all.

[get setting](https://docs.rual.nl/block-types/system%20settings/value_get_system_key_select) outputs the system setting picked on the block as a plain value. Here it is compared with a fixed [value](https://docs.rual.nl/block-types/value/value_default) using [==](https://docs.rual.nl/block-types/condition/condition_equal), so a [branch](https://docs.rual.nl/block-types/flow/branch) can switch behavior per environment.
