A safety device, comprising: a memory that stores executable components; an input terminal; an output terminal; and a processor, operatively coupled to the memory, configured to execute the executable components, the executable components comprising: a safe state detection component configured to determine whether the safety device is in a safe state; a pulse detection component configured to verify that a modulated pulse pattern contained in a safety signal portion of a cycle of a safety signal received on the input terminal corresponds to a defined pulse pattern; a status word control component configured to write device status data to a device data portion of the cycle of the safety signal; and a safety signal relaying component configured to output the cycle of the safety signal on the output terminal, characterized in that the safety signal relaying component is configured to output the cycle of the safety signal on the output terminal in response to the verification that the modulated pulse pattern corresponds to the defined pulse pattern and a determination that the safety device is in the safe state, and respective cycles of the safety signal comprise the safety signal portion containing the modulated pulse pattern and the device data portion separated by a separation gap (3702a, 3702b) having a defined duration. a memory that stores executable components; an input terminal; an output terminal; and a processor, operatively coupled to the memory, configured to execute the executable components, the executable components comprising: a safe state detection component configured to determine whether the safety device is in a safe state; a pulse detection component configured to verify that a modulated pulse pattern contained in a safety signal portion of a cycle of a safety signal received on the input terminal corresponds to a defined pulse pattern; a status word control component configured to write device status data to a device data portion of the cycle of the safety signal; and a safety signal relaying component configured to output the cycle of the safety signal on the output terminal, a safe state detection component configured to determine whether the safety device is in a safe state; a pulse detection component configured to verify that a modulated pulse pattern contained in a safety signal portion of a cycle of a safety signal received on the input terminal corresponds to a defined pulse pattern; a status word control component configured to write device status data to a device data portion of the cycle of the safety signal; and a safety signal relaying component configured to output the cycle of the safety signal on the output terminal, characterized in that the safety signal relaying component is configured to output the cycle of the safety signal on the output terminal in response to the verification that the modulated pulse pattern corresponds to the defined pulse pattern and a determination that the safety device is in the safe state, and respective cycles of the safety signal comprise the safety signal portion containing the modulated pulse pattern and the device data portion separated by a separation gap (3702a, 3702b) having a defined duration.
