| Description — This module provides 7 digital inputs and detects whether any wire between the switching device and the module or power supply is either short-circuited to ground or open-circuited. Communication is bidirectional. With an output image bit, you select what the module will write directly into the input image byte — the state of each input or the fault status of each input. | |||||||||
