PACSystems I/O System
The PACSystems I/O system provides the interface between the CPU and other devices. The PACSystems
I/O system supports:
▪
I/O and Intelligent option modules.
▪
Ethernet Interface
▪
Motion modules (RX3i)
▪
PROFINET: RX3i CPE330, CPE400 and RSTi-EP CPE100/CPE115 all permit one of their LANs to be
configured as an embedded PROFINET Controller (see Section 2.1.6,
).
Alternately, the RX3i PROFINET Controller IC695PNC001 installs in the RX3i Main I/O Rack
75
. The
embedded PROFINET Controller and the IC695PNC001 are used to control remote I/O drops. Refer
to
PACSystems RX3i & RSTi-EP PROFINET IO-Controller Manual
, GFK-2571G or later. Some examples
of remote drops are:
o
Standard rack-mounted I/O modules in RX3i racks scanned by the PROFINET scanner
IC695PNS001. Refer to
PACSystems RX3i PROFINET Scanner Manual
, GFK-2737
o
A mini-drop consisting of one or two I/O modules and supervised by the IC695CEP001. Refer to
PACSystems RX3i CEP PROFINET Scanner User Manual,
GFK-2883.
o
A Genius Bus supervised by a Genius Communications Gateway (IC695GCG001). Refer to
PACSystems RX3i Genius Communications Gateway User Manual
, GFK-2892.
▪
The Genius I/O system
o
RX7i: A Genius I/O Bus Controller (GBC) module provides the interface between the RX7i CPU
and a Genius I/O bus. Refer to
Series 90-70 Genius Bus Cont
roller User’s Manual
, GFK-2017.
o
RX3i: A Genius Communications Gateway (IC695GCG001) provides the interface between
devices on the Genius I/O bus and a PROFINET Controller (IC695PNC001) which is installed in
the RX3i Main I/O rack. Refer to
PACSystems RX3i Genius Communications Gateway User
Manual
, GFK-2892.
o
For information on Genius I/O, refer to
Genius I/O System User’s Manual,
GEK-90486-1 and
Genius I/O Analog and Discrete Blocks User’s Manual,
GEK-90486-2.

Note that RX3i CPE400 and RSTi-EP CPE100/CPE115 does not support IC695PNC001, since they are Standalone CPUs. Both
may co-exist on a PROFINET LAN.
