RSTI-EP PROFINET I/O Controller User Manual Section 1
GFK-2571R May 2021
Introduction 1
Section 1: Introduction
This Section introduces the PACSystems RX3i & RSTi-EP PROFINET system and describes the
various forms of RX3i & RSTi-EP PROFINET Controllers:
1. The IC695PNC001 module (abbreviated PNC001), which is a rack-mounted module
residing in the CPU Rack; there are two hardware versions of this module:
IC695PNC001-Ax and IC695PNC001-Bxxx. The differences are explained in Section
1.5.
2. The embedded PROFINET Controllers available in certain RX3i & RSTi-EP CPUs. At
publication, the IC695CPL410 (CPL410), IC695CPE400 (CPE400), IC695CPE330
(CPE330), and EPSCPE100/EPSCPE115 (CPE100/CPE115) permit LAN2 to be
configured as a PROFINET Controller.
The last two pages of this Section are a glossary that summarizes many terms used in the
manual.
Section 2:, Installation explains how to install a PNC001, how to complete port connections,
and how to update the PNC001 module firmware. Section 2: also explains how to install the
USB port driver on the PNC001 module (PNC001-Ax only) and describes how the module
synchronizes its internal clock with the RX3i CPU. Since embedded PROFINET Controllers
require no installation per se, refer to the installation instructions for the corresponding PLC
CPU.
Section 3:, Configuration explains how to complete and download the PACSystems RX3i &
RSTi-EP configuration for target PROFINET Controller, as well as devices present on the
associated PROFINET network. The associated devices typically include RX3i and VersaMax
PROFINET Scanners and third-party PROFINET devices but may also include additional
PROFINET Controllers present on the network.
Section 4:, PROFINET System Operation describes I/O scan operation and application
program function blocks for use with any RX3i & RSTi-EP PROFINET Controller (slot-
mounted or embedded). This Section also provides an overview of PROFINET
communications between the controller and IO-Devices.
Section 5:, Diagnostics
explains the power-up and reset process, special LED blink patterns, status reporting, and
fatal error reporting. It also describes faults and corrective actions.
Section 6:, Redundant Media, explains how a PROFINET system can be set up for PROFINET
Media Redundancy Protocol (MRP), and describes ring topologies that might be used.
Section 7:, Network Management explains the use of SNMP (Simple Network Management
Protocol) and Link Layer Discovery Protocol (LLDP) to assist network management. These
features are available in PNC001 firmware version 1.10 or later, and in all firmware versions
of CPL410, CPE400, CPE330, and CPE100/CPE115.

1.2 PROFINET Controller Description
This manual covers two types of PROFINET Controller:
1. The traditional Rack-mounted RX3i PROFINET Controller, IC695PNC001;
2. A PROFINET Controller that is embedded within a CPU.
1.2.1 PNC001 Description
The PACSystems RX3i PROFINET Controller module, IC695PNC001, connects a PACSystems
RX3i controller to a PROFINET network. It enables the RX3i controller to communicate with
IO-Devices on the network. The PNC001 provides all the functions, services, and protocols
required for certification as a PROFINET IO Version 2.2 IO Controller, running at both
100Mbps and 1Gbps.

RSTI-EP PROFINET I/O Controller User Manual Section 1
GFK-2571R May 2021
Introduction 4
The PNC001 supports 10/100/1000Mbps Copper,
100/1000Mbps Multi-mode Fiber, and
100/1000Mbps Single-mode Fiber. The network can
include media interfaces of more than one type.
PROFINET communications on the network require
100 and 1000 Mbps link speed. 10Mbps cannot be
used for PROFINET communications. However,
10Mbps can be used for other types of Ethernet
traffic, such as ping, and telnet.
Features of the RX3i PNC001 module include:
•Full programming and configuration services for
the PROFINET Controller, PROFINET Scanners
(PNS), and other third-party IO-Devices using
PAC Machine Edition.
•Firmware upgrades using the WinLoader
software utility.
•Built-in Command Line Interface function that
provides direct monitoring and partial
configuration via the module’s micro USB port or
using telnet. (PNC001-Ax only)
Note: The USB port is for system set-up and
diagnostics only.
It is not intended for permanent connection.
•Support for star, ring, and daisy-chain/line
network topologies.
•Four switched Ethernet ports —two 8-
conductor RJ45 shielded twisted pair
10/100/1000 Mbps copper interfaces and two
Small Form-factor Pluggable (SFP) cages for
user-supplied SFP devices.
•Support for media redundancy
•Internal clock synchronized with the RX3i CPU
for time-stamped diagnostics entries.
•Restart pushbutton to manually restart the
module without power cycling the system.
•LEDs: OK, LAN, STATUS, CONFIG, ACTIVE, USB
(PNC001-Ax only), and Port Number LEDs as
shown in Figure 2 and Figure 3.

In the case of CPE330, with embedded PROFINET activated, it is possible to have five PROFINET Controllers. However, in the rare case of
having all 5 PNCs configured on the same LAN, and then invoking redundancy, each CPU is again restricted to a limit of 4 PNCs (in order to
satisfy the overall limit of 8 PNCs per LAN).

Introduction 8
Maximum Number of Nodes per Network based on Topology
•For a network using MRP ring topology, the maximum number of nodes is 64
(consisting of the PNC001 PROFINET Controller(s) plus up to 62 or 63 IO-Devices). If the
ring uses Media Redundancy Protocol, this means one Media Redundancy Manager and
up to 63 clients.
•For a network using MRP ring topology and an Embedded PROFINET IO-Controller as
the MRP Ring Manager, the maximum number of nodes is
- for CPE330/CPE400: 32 (1 MRP Manager and 31 MRP clients)
- for CPL410: 64 (1 MRP Manager and 63 MRP clients)
- for CPE100/CPE115: 9 (1 MRP Manager and 8 MRP clients).
•For a network using star topology, the maximum number of nodes configurable is 263
(consisting of up to 8 PNC001 PROFINET Controllers plus up to 255 IO-Devices).
•For a network using star, line topology, or MRP Ring (where the Embedded PROFINET
IO-Controller is not the MRP Ring Manager) the maximum number of nodes
configurable of the system is 264. This may consist of up to eight IC695PNC001
PROFINET Controllers and one Embedded PROFINET IO-Controller (CPL410, CPE400 or
CPE330) plus up to 255 I/O-Devices.

1.4.1 Operating Temperature De-Rating:
The operating temperature range is specified for the module and not the system. As a
guideline, if the module is next to hot neighbor modules on each side the maximum
operating ambient temperature should be de-rated as described below:
•If 100 MB Fiber SFPs installed, then reduce by 5°C
•If Copper SFPs operating at 1 GB, then reduce by 6°C

1.5.1 PNC001 Hardware Implementations (-Ax & -Bxxx)
In January 2018, an updated hardware implementation(-Bxxx) replaced the earlier version
(-Ax) of the rack-mounted PNC001. The PNC001-Bxxx is a drop in replacement for the
PNC001-Ax.
The following are the differences between these two hardware implementations:

1.5.2 Ethernet Network Ports
Figure 4 shows the underside of the PNC001 module.
•Ports 1 and 2 are standard RJ45 connections.
•Ports 3 and 4 offer Small Form-factor Pluggable (SFP) cages
The PROFINET Controller connects to a PROFINET network via one or more of its four
external switch ports. Two 8-conductor RJ45 shielded twisted pair 10/100/1000 Mbps
copper interfaces and two SFP cages provide flexibility in media selection and the ability to
use redundant media for the PROFINET network. Use of redundant media must first be set
up in the module configuration. Section 6: provides additional information about
Redundant Media.
The PROFINET protocol supported by the PACSystems RX3i PROFINET modules can be sent
and received over any of the four external ports on PNC001.
The PNC001 module is assigned five Ethernet MAC addresses: one for each of the four
external Ethernet ports and one for the internal switch.

Introduction 12
Figure 4: PNC001 Ethernet Ports Location and Type
For the Embedded PROFINET LAN (LAN2), CPL410, CPE400 and CPE330 both provide two
RJ45 ports identical to those shown as Port 1 and Port 2 in Figure 4. The operational
behavior, configuration parameters and diagnostics are also identical. Refer to the
corresponding product documentation for further details.
Small Form-factor Pluggable (SFP) cages (like Port 3 and Port 4 in Figure 4) are not offered
on CPL410, CPE400, CPE330 nor on CPE100/CPE115.
Figure 5: CPE100/CPE115 Ethernet Ports Location and Type
The CPE100/CPE115 Embedded PROFINET LAN (LAN2) supports three switched 8-
conductor RJ45 shielded twisted pair 10/100 Mbps copper interfaces ports as shown in
Figure 5. The operational behavior, configuration parameters and diagnostics are identical
to PROFINET port of CPE400. Refer to the corresponding product documentation for further
details.
CPE100/CPE115 LAN2 Port 2 and Port 3 can use redundant media for the PROFINET
network. Use of redundant media must first be set up in the module configuration. Section
6 provides additional information about Redundant Media.
Ethernet Port Status Indicators
Each external switched port has an associated link-up/link-down status bit that can be
monitored by the RX3i CPU to check the operating status of the port (see Status Reporting
in Section 5: Diagnostics
for information about the PROFINET Controller status bits). In addition, the Port Number
LEDs on the front of the module provide a visual indication of the port status.

Introduction 13
1.5.3 USB Port(s)
The USB ports on the CPUs that support embedded PROFINET operate independently of the
PROFINET function. Refer to the corresponding product documentation for further details.
The PNC001-Bxxx module has no micro USB port, and therefore does not support the
Command Line Interface.
The PNC001-Ax module has a micro USB port for connection to a computer running
Windows® 2000, Windows XP, Windows Vista®, Windows 7 or Windows 10. On the
PNC001 module (-Ax version) only, the USB port can be used to access the Command Line
Interface (CLI) function using a terminal emulation application such as HyperTerminal.
The Command Line Interface function can be used to monitor a PROFINET Controller
module and check its operation. If a problem occurs, the Command Line Interface can be
used help determine the cause.
A driver-install application is provided to set up a computer to communicate with the USB
port (see Section 2:, Installation, for instructions).
1.5.4 Reset Pushbutton
The Reset pushbutton on a PNC001 module can be used to manually reset the module
without cycling power. The restart operation commences when the pushbutton is released.
1.5.5 LEDs on the CPUs with Embedded PROFINET
Refer to the corresponding product documentation for further details.
1.5.6 LEDs on the PNC001 Module
