Module
The virtual I/O Master Module serves for the acquisition or output of process signals and per-
forms the process-compliant adaptation, monitoring and processing of the process signals at
each point of entrance or exit of the system. Its functionality is provided by means of a
loadable and parameter-settable firmware.
