PROFINET Networks for PACSystems

PROFINET is an open standard for industrial automation that is based on Industrial Ethernet. The
PROFINET IO framework allows the creation of I/O data exchanges between controllers and
distributed devices. It also allows configuration, parameterization, and diagnostics communication
between controllers and devices.
Note: The PROFINET Controller operates only in autonegotiate mode. All PROFINET bus
devices and switches that are connected to the PROFINET Controller should be
configured to use autonegotiation.
Basic System: One RX3i CPU and One PROFINET Controller using a
single port
Components of the RX3i PROFINET network consist of a PACSystems RX3i PNC module in the
RX3i main rack communicating with IO Devices on the PROFINET bus. The main RX3i rack can
include up to four PNCs, each communicating with its own high-speed network. IO Devices on the
network can include VersaMax PNS modules and a wide range of third-party devices. For example,
the illustration below shows a basic system with one PACSystems RX3i CPU node having one PNC,
and one PROFINET network with three VersaMax Scanners and one third-party IO-Device. Up to 64
IO-Devices can be installed on an RX3i PROFINET network. The VersaMax PNS and many types of
third-party IO-Devices interface multiple devices such as I/O modules to the PROFINET network.
