CPU Operation 108
4.10 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, CPL410 and RSTi-EP CPE100/CPE115 all permit one of their
LANs to be configured as an embedded PROFINET Controller (see Section 2.1.5,
Embedded PROFINET Controller). Alternately, the RX3i PROFINET Controller
IC695PNC001 installs in the RX3i Main I/O Rack
. 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:
▪ Standard rack-mounted I/O modules in RX3i racks scanned by the PROFINET scanner
IC695PNS001and IC695PNS101. Refer to PACSystems RX3i PROFINET Scanner Manual,
GFK-2737.
▪ 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.
▪ 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
▪ A Genius I/O Bus Controller (GBC) module provides the interface between the CPU
and a Genius I/O bus. Refer to Series 90-70 Genius Bus Controller User’s Manual, GFK-
2017.
▪ 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.
