^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		for the respective channel of Signal Y. Valid attribute values
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		are boolean. Detection must first be enabled via the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		corresponding cable_fault_enable attribute.
