communication method
RT (real-time)
communication
Uses standard Ethernet
hardware and achieves
the same level of
performance as the
existing Fieldbus.
Supported
IRT (Isochronous
real-time) communication
This method provides a
higher level of assurance
than RT that
communication will be
executed within a specific
time. Intended for use in
systems such as motion
control that require strict
real-time.
Not supported
