摘要： A system serializes control signals within a safety control architecture wherein a safety serial interface at least one of receives and transmits signals from one or more processing components. A serialization component receives and serializes at least one data packet from the safety serial interface to control at least one of an input and an output associated with the safety control architecture. A safety related test circuit verifies input signals associated with the serialization component are not internally falsifying the state of the input signals. A heartbeat watchdog component verifies a true heartbeat bit in the at least one data packet is opposite a complement heartbeat bit in the at least one data packet within a predetermined time interval and shuts off power to at least one of an output and an input if such a condition is not met.

摘要： A frequency monitor provides high resolution frequency monitoring over a range of input signal frequencies by measuring the time period of the signal to produce a raw frequency value and then filtering the raw frequency value with a low pass filter to remove an error component caused by quantization effects at high input signal frequencies. The system automatically accommodates changes in the input frequency eliminating a need for manual adjustment of the system based on anticipated measured frequencies.

摘要： A current loop drive module includes a drive circuit and a compliance voltage controller. The drive circuit is configured to receive a compliance voltage and operable to generate a current loop signal based on the compliance voltage for receipt by an associated load coupled to the drive circuit. The compliance voltage controller is operable to adjust the compliance voltage based on the associated load. A method for generating a current loop signal includes generating a current loop signal based on a compliance voltage for receipt by an associated load and adjusting the compliance voltage based on the associated load.
