Profinet
The Profinet fieldbus MI3 communication box (called fieldbus communicator) maps the object and
internal temperature of all pyrometer modules on Profinet IO. In the initialization phase, the fieldbus
communicator determines the physical structure of the node and creates a local process image with all
pyrometers.
The diagnostics concept is based on channel specific diagnostic messages that are mapped to the
respective alarms. Coding is done according to IEC 61158 Profinet IO.
