Predefined Input Acquisition
Presentation
The IO module can acquire predefined indications delivered by external devices through digital inputs for signalization purposes: the status of the input with its predefined description is displayed on FDM121 display.
The predefined indications that can be assigned to digital inputs are listed in the following table. Each change of state of a predefined input generates an event. For more information on the IO module events, refer to Events and Alarms.
