Overview

Process I/O and human interface functions are, of course, the field of the automation / application programmer. This task is facilitated by weAutSys providing the basic hardware abstraction functions to access the I/O periphery.

Process I/O here means the device's (weAut_01's) protected I/O to the "field" through clamps and connectors and not the internal (un-protected) extension and instrumentation ports.

HMI here means the device's (weAut_01's) visible display LEDS and its (2) switches and not any HMI through serial and Ethernet communication links.
