Chapter 1 Introduction

This chapter 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 1.5.1.

2. The embedded PROFINET Controllers available in certain RX3i & RSTi-EP CPUs. At publication, the

IC695CPE400 (CPE400), IC695CPE330 (CPE330) and EPSCPE100/EPSCPE115 (CPE100/CPE115)
permit LAN2 to be configured as a PROFINET Controller.

The last two pages of this chapter are a glossary that summarizes many terms used in the manual.

Chapter 2, Installation explains how to install a PNC001, how to complete port connections, and how to
update the PNC001 module firmware. Chapter 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.

Chapter 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.

Chapter 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 chapter also provides
an overview of PROFINET communications between the controller and IO-Devices.

Chapter 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.

Chapter 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.

Chapter 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

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.

The PNC001 supports 10/100/1000Mbps Copper, 100/1000Mbps Multi­mode 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 IO­Devices using PROFICY 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.

1.2.2 Embedded PROFINET Controller

CPE400, CPE330 and CPE100/CPE115 feature an Embedded PROFINET IO-Controller function. This feature
permits LAN2 to be configured as a PROFINET Controller similar to PNC001 in functionality, but without
requiring the presence of a PNC001 rack-mounted module.

In the following Specifications section, the physical specifications related to rack mounting do not apply to the
embedded PROFINET Controllers. Refer to the corresponding product documentation for CPE400, CPE330 and
CPE100/CPE115 in the PACSystems RX7i, RX3i and RSTi-EP CPU Reference Manual, (GFK-2222AB or later).

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. Chapter 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.

Figure 4: PNC001 Ethernet Ports Location and Type

For the Embedded PROFINET LAN (LAN2), 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 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 have the ability to use redundant media for the PROFINET network.
Use of redundant media must first be set up in the module configuration. Chapter 6 provides additional
information about Redundant Media.

Chapter 1. Introduction

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 Chapter 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.

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 Chapter 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

The table below summarizes LED functions on the PNC001 module. More detailed information about error
indications and special blink patterns is given in Chapter 2, Installation and Chapter 5, Diagnostics.

OK

Green ON indicates that the module is able to perform normal operation.

LAN

Indicates network packets are being processed by the network interface (not just passing through the
embedded switch).

STATUS

Indicates the condition of the PROFINET Controller during normal operation. It indicates whether an entry
other than the start-up event is present in the module’s Local Log. STATUS can also indicate whether any of
the MAC addresses are invalid.

CONFIG

Indicates whether the module has received its configuration from the RX3i CPU.

ACTIVE

Indicates the status of PROFINET connections.

USB

Indicates activity on the USB port. (PNC001-Ax only)

Port
LEDs

Indicate link speed, link connection and link activity corresponding to the four possible external Ethernet
ports.

1.6 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 auto-negotiate mode. All PROFINET bus devices and

switches that are connected to the PROFINET Controller should be configured to use auto­negotiation.

The following products support PROFINET I/O:

communicating with IO Devices on the PROFINET bus.

The PROFINET Controller may be an embedded PROFINET Controller (CPE400 or CPE330 or CPE100/CPE115)
or a rack-mounted PNC001 module located in the RX3i CPU rack. For rack-mounted PNC001 units, the main
RX3i rack can include up to four PNC001 modules, each communicating with its own high-speed network.

IO Devices on the network can consist of the I/O modules installed in a rack, each containing a PROFINET
Scanner (PNS) as its head-end, such as the GE products listed above. The network may also include a wide
range of third-party IO Devices, such as pressure gauges and motor actuators, that are connected directly to
the PROFINET network.

1.6.1 Compression

Due to the smaller memory capacities of CPE302, CPE305 and CPE310, these CPUs require "Compression"
when attaching RX3i PNS or CEP to their PROFINET configuration.

• CPE302: User MUST use Target PLC parameter with "Compression" set to HIGH.

• CPE305: User MUST use Target PLC parameter with "Compression" set to MODERATE.

• CPE310: User can use Target PLC parameter "Compression" set to NORMAL.

• All other CPUs: User can choose to use "Compression" or not.

The illustration below shows a basic system with one PACSystems RX3i CPU node that has one RX3i PROFINET
Controller module controlling one PROFINET network. The network can connect up to 128 compatible IO­Devices, including any combination of GE PROFINET Scanners and third-party IO-Devices.

Figure 7 shows one RX3i PROFINET Controller that is directly connected to four separate IO-Devices in a Star
topology. Although each IO-Device is connected to a separate Ethernet port on the PNC001, they are all on the
same network segment (IO LAN1). The IO-Devices in this example are all VersaMax PROFINET Scanners, but
RX3i PROFINET Scanners (PNS001) and third-party IO-Devices may also be used.

1.6.4 Basic System: Third-Party Devices and PME Programmer

Third-party IO Devices can be used with the RX3i PROFINET Controller if their manufacturer provides a GSDML
file that can be imported into Proficy Machine Edition (PME). The GSDML file defines the characteristics of the
IO-Device and its I/O modules. Importing a third-party IO-Device GSDML file and configuring third-party IO­Devices are described in Chapter 3, and in the Proficy Machine Edition online help.

After receiving a third-party device’s configuration, the RX3i PROFINET Controller connects to the third-party
IO-Device if the device is available, transfers the configuration to the device, and starts exchanging I/O and
alarm data with the device.

Figure 8 shows a programmer connection (for configuration, user logic programming, and monitoring), the
concept of GSDML import, an optional external Ethernet switch, and the ability to connect field buses to a
PROFINET IO-Device. Third-party IO-Devices that have only one Ethernet port may require the use of an
external switch.

Both examples in this section show systems with one RX3i CPU that has two PROFINET Controller modules.
The PROFINET network can serve up to 63 IO-Devices (ring topology) or 128 IO-Devices (in star topology).

Note that multiple PNC001 modules in the same rack are not synchronized; that is, no two PNC001 modules
are guaranteed to power up at the same time. PNC001 configuration differences (SFPs, etc.) can also cause
variations in PNC001 power-up times.

If two (or more) PNC001 modules are in a main rack and devices owned by one PNC001 are routed through the
switch on a different PNC001 in the same rack, devices may show a Loss of Device fault followed by an Addition
of Device fault during RX3i power-up because the first PNC001 can power up before the second PNC001 has
enabled its Ethernet switch, causing the Loss of Device. Then when the second PNC001 powers up, the device
will show an Addition of Device fault, which is to be expected under these circumstances. Devices will function
normally once added.

As shown in Figure 9, both PROFINET Controllers are connected to the same network.
