1. Introduction

1.1 General

Modern field bus systems, microcontrollers and communication networks have had a great influence on automation systems and have resulted in greater flexibility, availability, and ultimately, a reduction in costs.
The widespread use of PC-based control only became possible with the availability of field bus systems. With increasing control unit performance, the classic field bus ultimately became the limiting criterion for the entire system. It was therefore an obvious step to adapt Ethernet technology, which provides high rates of data transmission in IT applications, to the field of automation.
EtherNet/IP™ (Ethernet Industrial Protocol) is an Ethernet-based field bus. This is an open standard, which is administered by the users' organisation ODVA.

1.2 Bus modules

Specific bus modules are available as interfaces between the field bus system and the NORD system bus or the NORD frequency inverter. A document exists for each module (Technical Information / Data Sheet), which includes the technical data, as well as installation and configuration information (www.nord.com).

NOTICE
Potential equalisation
If earthing potential values are different, transient current may flow through shielding which is connected on both sides. This may be a danger to electronic components. Differences in potential must be reduced by means of adequate potential equalisation.

2. Bus Configuration

2.1 Topology

Up to 255 NORD bus modules can be integrated into an EtherNet/IP™ network. The network can be configured either with a ring topology or as a linear bus. Configuration in a star topology is also possible, however only with the use of a corresponding switch.
The length of cable between two neighbouring devices must not exceed100m. Detailed information about the bus modules is contained in the relevant Technical Information / Data
Sheets.

2.2 Cable layout and shielding (EMC measures)

If EMC measures are not in place, high-frequency interference which is mainly caused by switching processes or lightning often causes electronic components in the bus subscribers to be faulty and error-free operation can no longer be ensured.
Appropriate shielding of the bus cable reduces electrical interference which can arise in an industrial environment.
The best shielding qualities can be achieved with the following measures:
• Do not make cable connections shorter than 1 m between bus participants
• Avoid long connections between bus participants
• Shield the bus cable at both ends with large-area connection to the plug housing
• Avoid spur lines
• Avoid extensions to bus cables via plug connectors
Bus lines should be laid with a minimum spacing of 20 cm to other lines which carry a voltage higher than 60 V. This applies to lines laid inside and outside of control cabinets.
Special attention should be paid to bending radii:

3 Configuration in the Bus System
1.
IP address via DHCP or BOOTUP mode
Select the addressing mode in the module parameter P165 and then configure the module via Ethernet.
2.
IP address via module parameter
Carry out addressing via the module parameters P160, P161 and P164. P165 must have the value "0" (default value).
3.
IP address via DIP switch
Alternatively: The last byte of the IP address can be set via the DIP switches on the module. (refer to the
Technical Information or Data Sheet for the module ( LINK)
Information
Adoption of the address
All settings to the parameters P160 ... P165 and the DIP switches are only adopted after a bootup (restart of the module).
Step
Action
1.
Install the eds file in the PLC interface
2.
Integrate the bus module from the PLC database into the project.
3.
Configure the assembly
4.
Configure the IP address

3. Configuration in the Bus System

3.1 Addressing

The addressing of the EtherNet/IP™ module (SK xUx-EIP-…) can be performed by three methods:
The resulting settings of the IP address and the sub-net mask can be read out in parameters P185 and P186.

3.2 Integration into the busmaster

In order to be able to use the devices in the bus system, they must be integrated into the PLC or the project.
The necessary device data for the bus devices are saved in the electronic data sheets (eds files). According to the module, various eds files are available. These can be downloaded free of charge from www.nord.com.

Information
PLC Busmaster
By means of certification, NORD ensures that the bus system complies with the requirements which are made by the bus interfaces.
Various planning tools or control systems are commercially available. NORD assumes that the user who integrates the NORD bus module into the relevant control unit has the necessary knowledge of the bus system and is sufficiently familiar with the use of the planning tool or PLC.

3.3 Remote Maintenance (in preparation)

With the aid of the NORD CON software it is possible to access the module via the Internet for maintenance purposes. The data transfer is carried out with encryption via a secure connection. Authentication is by means of a password, which can be saved in the module (Parameter P169).
The access rights for remote maintenance are assigned with DIP switch and range from "read only parameter" (default) to "reading and writing access of parameters" and "remote control of the drive unit".
(For details, please refer to the "Technical Information / Data Sheet for the bus module).
4 Communication and Protocol

4. Communication and Protocol

4.1 Processing of Process Data in the Frequency Inverter

In the process data area (PZD), control words and setpoints are transferred from the master to the frequency inverter and in return, status words and actual values are sent from the frequency inverter to the master. The structure of the PZD area is always the same in terms of the sequence of its elements (words), however, dependent upon direction of data Master Slave / Slave Master, it is described differently. Each word has a length of 16 Bit. To communicate 32 Bit values (e.g. position values), 2 words are required (e.g setpoint 1 and setpoint 2).
