Parameterization monitoring for analog signal modules

摘要

The invention relates to a method for monitoring an output driver that can be parameterized and is suitable for controlling actuators in industrial automation technology, for applying analog signals to an output channel, with the following steps: determining resulting internal leakage power based on the parameterization data provided for parameterizing the output driver, comparing the leakage power relative to a leakage power limiting value, and, dependent functionally on the comparison result, stopping the application of an analog signal on the output channel corresponding to the parameterization data provided for parameterizing the output driver. The invention further relates to an analog signal output device, suitable for controlling actuators in industrial automation technology and in accordance with the aforementioned method, comprising at least one output driver and a monitoring device.
