# [SPECIAL PROPERTIES](#SPECIAL_PROPERTIES)

## [switch\_closed.\[0-3|ALL|BYTE\]](#switch_closed._0-3_ALL_BYTE_)

*read-only, yes-no*  
Is the relay closed? (1=yes, 0=no).

Note that *OWFS* uses 0 through 3 as the index and the datasheet uses 1 through 4.

## [loop\_shorted.\[0-3|ALL|BYTE\]](#loop_shorted._0-3_ALL_BYTE_)

*read-only, yes-no*  
Is the loop shorted? (1=yes, 0=no). Failsafe mode.

Note that *OWFS* uses 0 through 3 as the index and the datasheet uses 1 through 4.

## [loop\_open.\[0-3|ALL|BYTE\]](#loop_open._0-3_ALL_BYTE_)

*read-only, yes-no*  
Is the loop open? (1=yes, 0=no). Failsafe mode.

Note that *OWFS* uses 0 through 3 as the index and the datasheet uses 1 through 4.
