3.1.2 Network

It is of high importance that the media chosen for Ethernet data transmission are suitable. Usually CAT 5e and 6 cables are recommended for industrial applications. Both types are available as Unshielded Twisted Pair and Shielded

Twisted Pair. Generally shielded cables are recommended 3 3 for use in industrial environments and with frequency

converters.

A maximum cable-length of 100m is allowed between switches.

Optical fibres can be used for gapping longer distances and providing galvanic isolation.

For connecting PROFINET devices both hubs and switches can be used. It is, however, recommended always to use suitable industrial graded Ethernet switches. GE recommends always to use PROFINET compliant switches

How to Install	PROFINET Operating Instruction

3.1.3 PROFINET Cables

PROFINET cables used are based electrically on category 5 balanced LAN cables according to ISO/IEC 11801 Edition 2.0, Class D.

Type C cables can be used in special applications (e.g. the use of trailing cables and frequently moved machine parts) even though their design and mechanical parameters can deviate from the specifications of type A and type B cables. Still most

3 3 of the electrical parameters (impedance levels etc.) are retained. Highly flexible copper cables generally have the finest stranded conductors and, for example, a highly resistant polyurethane outer sheath.

Various outer sheath materials are permitted in order to meet the various demands with regard to resistance of industrial environments and exterior/underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low temperatures, UV radiation).

All balanced cables used shall comply with the following parameters:

Cable Type		Application Type A	Application Type B		Application Type C

3.1.5 Topology

The PROFINET module features a built-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several PROFINET options in a line topology as an alternative to the typical star-topology.

The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, both ports can	3	3
be used.

Illustration 3.4 Star Topology

Illustration 3.5 Line Topology

11

How to Install PROFINET Operating Instruction

NOTE

In a line topology all drives must be powered, either by mains or by their 24V DC option cards, for the built-in switch to

work.

Please observe that mounting drive of different power-sizes in a line topology may result in unwanted power-off behavior,

while using controlword timeout (O-02 Control Word Source to O-06 Reset Control Word Timeout. It is recommended to

mount the drives with the longest discharge time first in the line topology.

Illustration 3.6 Ring/Redundant Line Topology

CAUTION

For this type of topology it is crucial that the network switch supports detection of loss of line topology. In some cases the detection. The switch inside the PROFINET option does not support this, but it must be supported in the switch that connects the ring to the controller/network Please consult the manual of the switch for more information.

How to Install	PROFINET Operating Instruction

3.1.6 Recommended Design Rules

While designing Ethernet networks special attention and caution must be taken regarding active network components. While designing a network for line topology it is important to notice that a small delay is added with each switch in the line.

It is not recommended to connect more than 32 drive in a line. Exceeding the recommended design rules, may result in																										3	3
unstable or faulted communication.

3.1.7 EMC Precautions

The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network. Additional EMC information is available in the AF-600 FP/AF-650 GP series Design Guide.

3 3 NOTE

Relevant national and local regulations, for example regarding protective earth connection, must be observed.

The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise from one cable to the other. Normally a distance of 200mm (8 inches) is sufficient, but maintaining the greatest possible distance between the cables is recommended, especially where cables run in parallel over long distances. When crossing is unavoidable, the Ethernet cable must cross motor and brake resistor cables at an angle of 90°.

	using fixed leases together with DHCP or BOOTP, the	4	4
	physical MAC address is linked with a fixed IP address.

NOTE

If no DHCP or BOOTP reply has been received after 4 attempts (e.g. if the DHCP/BOOTP server has been powered off), the option will fallback to the last functioning IP address.

EN-03 Default Gateway is optional and only used in routed networks.

EN-06 Name Servers

EN-07 Domain Name EN-08 Host Name

are used with Domain Name Server systems and are all optional. If DHCP or BOOTP is selected as IP address assignment, these parameters are read only.

NOTE

It is only possible to assign valid class A, B and C IP address to the option. The valid ranges are shown in

Table 4.3:

Class A 1.0.0.1 - 126.255.255.254

Class B 128.1.0.1 - 191.255.255.254

Class C 192.0.1.1 - 223.255.254.254

4.1.2 Ethernet Link Parameters

Parameter group EN-1# holds information Ethernet Link information:

EN-10 Link Status
EN-11	Link Duration
EN-12 Auto Negotiation
4 4 EN-13	Link Speed
EN-14	Link Duplex

Please note the Ethernet Link Parameters are unique per port.

EN-10 Link Status and EN-11 Link Duration displays information on the link status, per port.

EN-10 Link Status will display Link or No Link according to the status of the present port.

EN-11 Link Duration will display the duration of the link on the present port. If the link is broken the counter will be reset.

EN-12 Auto Negotiation - is a feature that enables two connected Ethernet devices to choose common transmission parameters, such as speed and duplex mode. In this process, the connected devices first share their capabilities as for these parameters and then choose the fastest transmission mode they both support.

Incapability between the connected devices, may lead to decreased communication performance.

To prevent this, Auto Negotiation can be disabled.

If EN-12 Auto Negotiation is set to OFF, link speed and duplex mode can be configured manually in EN-13 Link Speed and EN-12 Auto Negotiation.

EN-13 Link Speed - displays/sets the link speed per port. “None” is displayed if no link is present.

EN-14 Link Duplex - displays/sets the duplex mode per port. Half-duplex provides communication in both directions, but only in one direction at a time (not simultaneously). Full-duplex allows communication in both directions, and unlike half-duplex, allows for this to happen simultaneously.

5 How to Configure the System

5.1 Configure the PROFINET Network

All PROFINET devices that are connected to the same network must have a unique device name.

The PROFINET device name of the frequency converter can be set via:

EN-08 Host Name

5.2 Configure the Controller

5.2.1 GSD File

In order to configure a PROFINET Controller, the configuration tool needs a GSD file for each type of slave on the network. The GSD file is a PROFINET standard text file containing the necessary communication setup data for a slave. Download the GSD file for the AF-6 Series drives at www.geelectrical.com/drives. The name of the GSD file may vary compared to this manual. Please download the latest version from the above website.

The first step in configuration of the PROFINET Controller is to import the GSD file in the configuration tool. The steps

outlined below show how to add a new GSD file to the Simatic Manager software tool. For each drive series, a GSD file is typically imported once only, following the initial installation of the software tool.
