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.
Page 10
EtherNet/IP Bus module – Supplementary manual options for NORD - Frequency Inverters
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).

4.1.3 Frequency inverter status machine

The frequency inverter passes through a status machine. The changes between various states are triggered by the respective control commands in the process data control word. The actual status is returned in the process data status word.
After switching on, the inverter is in switch-on disabled status. This status can only be ended by transmitting the “Shut down (Off 1)” command.
The answer to a master telegram normally does not yet contain a reaction to the control command. The controller must check the answers from the slaves as to whether the control command has been carried out.
The following bits indicate the status of the frequency inverter:

4.1.4 Setpoint (SW) and Actual Value (IW)

The functions of the setpoint and the actual value are assigned via frequency inverter parameters:
The following three kinds of data transfer are possible:
Percentage transfer
The process value is transferred as an integer with a value range of -32768 to 32767 (8000 hex to 7FFF hex). The value 16384 (4000 HEX) corresponds to 100 %. The value -16384 (C000 hex) is equal to -100 %.
For frequencies, the 100 % value corresponds to the FI parameter "Maximum Frequency" (P105) and for currents, this is the FI parameter "Torque Current Limit" (P112) Frequencies and currents result from the following formulae.
"Value" represents the 16Bit actual or setpoint value transmitted via the bus
Binary transmission
Inputs and outputs, as well as Digital In bits and Bus Out bits are processed bit-by-bit.
Transmission of positions
In the FI, positions have a value range of +/- 50000.000 rotations. A motor rotation can be divided into a maximum of 1000 steps. This scaling is independent of the encoder which is used.
The 32 Bit value range is divided into a Low word and a High word, so that 2 setpoints or actual values are required for the transfer. It does not matter which 2 words (except for the 1st word) are used for this.
Table 5: Depiction of 32Bit setpoint/actual values
It is also possible to only transmit the Low component of the position. This results in a limited value range from +32,767 to -32,768 rotations. This value range can be extended with the aid of the gear ratio factor (P607 & P608). However, it must be noted that there is an according reduction in the resolution.

4.1.5 Example: "Switch on and off + setpoint"

In this example, a frequency inverter is controlled with a setpoint (setpoint frequency). The frequency inverter responds with an actual value (actual frequency). The "maximum frequency" is parameterised to 50 Hz.

4.2 Transfer of Data in the Bus System (I/O connections)

Process data is exchanged between the SK xUx-EIP bus module and the EtherNet/IP Master via I/O connections. An "Exclusive Owner" connection can be opened, through which the setpoints and actual values can be exchanged. In addition, two "Listen Only" connections can be opened, through which the actual values of the FI can be read.

4.2.1 Assembly

Only process data, but no protocol information can be transmitted via the I/O Message Object. Assignment of the relevant setpoints and actual values is performed via the Assembly Object. The following table lists several pre-defined configurations (Instances).

Coding of the FI parameters into the EtherNet/IP™ format is performed as follows:

Formation of the instance

The formation of the instance depends on the structure of the relevant parameter. The following applies for parameter set-dependent parameters without an array (e.g. P103):
The following applies for parameters which do not depend on a parameter set, but which have an array (e.g.P465):
The following applies for parameters which depend on a parameter set and also have an array (e.g. P400):

4.4 Timeout monitoring

The Ethernet monitors the data traffic by means of the bus system watchdog. Monitoring by the frequency inverter is also possible.
Monitoring by the inverter is is triggered if the process data contact is interrupted or the process data is transferred with an invalid control word (Bit10 in control word = 0). This function is activated when the first valid process data telegram is received.

5 Parameter
Information
Deviating Parameter Settings
According to the type or equipment of the frequency inverter, individual parameters may be different or restricted.
Information
Control terminal functions
When activated, the functions block voltage, quick stop, remote control and cancel error, are available at the (local) control terminals. To operate the drive, a High signal must be present on the digital inputs being used before the drive can be enabled.

5. Parameter

In order to operate the frequency inverter on the bus system, some parameter settings must be made on the bus interface and on the frequency inverter.
The frequency inverter can always be parameterised. The control source can be selected with parameter P509 (control word) and parameter P510 (setpoint source). The telegram down time P513 can be selected depending on the bus system.
