Introduction to the Fieldbus

1 INTRODUCTION TO THE FIELDBUS

The Fieldbus is a digital communication system used in the industry to connect primary automation elements,

such as PLCs, drives, valves, sensors, actuators etc., as illustrated in the

Figure 1.1 below.

Figure 1.1: Illustration of a Fieldbus network

The concept that was born at the end of the 1980s, it appeared as an alternative to the limited analogue

systems (4-20mA and +/-10V). In the analog control, the installation of long wires and cables from each device

to the central controller was frequent. This led to high cabling costs, difficult maintenance and also

compromised the system expansion.

The first industrial digital networks that appeared used proprietary solutions created by big manufactures. There

was no concern with interaction or standardization. The customer options regarding suppliers were restricted.

However, the crescent demand for process improvements turned this situation around. Several technologies

appeared. Standardization became important because of the involved costs. Organizations responsible for the

promotion and update of networks and protocols, many of them open, were created. User groups with the

purpose of mutual help also appeared.

Nowadays, there is a great variety of protocols in the market, each one with its advantages and disadvantages.

It is up to the user/project designer to evaluate what the necessary requirements for the application are, and

choose among the available options.

Regardless of the choice, the main advantages of the industrial networks are:

 Significant reduction in cable and installation costs;

 Reduction of the start-up time;

 More reliability and efficiency;

 Addition, removal and replacement of equipment with the network under load (supply);

 Integration of several suppliers (standardization);

 Effective process monitoring;

 Device configuration through the network.

The SSW supports, by means of the Anybus-CC communication module, three protocols widely spread in the

industry: DeviceNet, Profibus DP-V1 and EtherNet/IP.

The characteristics of the Anybus-CC modules available for the SSW, as well as the protocols used by these

modules, will be presented next.

SSW7000| 8

Accessory Kits (active modules)

2 ACCESSORY KITS (ACTIVE MODULES)

In order to make available a DeviceNet, Profibus DP-V1 or EtherNet/IP interface for the SSW, it is necessary to

use one of the communication kits described next. Information on the installation of these kits can be obtained

in the guide that comes with them.

2.1 DEVICENET

2.1.1 DEVICENET-05 Kit

 WEG part number: 10413655.

 It is composed by the Anybus ABCC-DEV communication

module, mounting instructions and a torx screwdriver for fixing

the module.

 ODVA certified interface.

 It allows the programming of the drive via network

configuration software.

2.1.2 Connector Pinout

The DeviceNet communication module presents a male plug-in connector with the following pinout:

2.1.3 Indications

 MS LED: bicolor LED (green/red). It indicates the communication module status.

 NS LED: bicolor LED (green/red). It indicates the DeviceNet network status.

For a better interpretation of the indications above, refer to the sections

5.9 and 5.10.

2.1.4 Connection to the Network

For the connection of the using the active DeviceNet interface, the following points must be observed:

 It is recommended to use cables specific for CAN/DeviceNet networks.

 Grounding of the cable shield at only one point, thus avoiding current loops. This point is normally the

network own power supply. If there is more than one power supply, they must be referenced to the same

point.

 Termination resistors must be installed only at the extremes of the main bus, even if there are derivations.

 The network power supply must be able to supply the current for all the equipment transceivers. The SSW

DeviceNet module consumes approximately 50 mA.

SSW7000| 9

Accessory Kits (active modules)

2.1.5 Module Configuration

In order to configure the DeviceNet module, follow the steps indicated below:

 With the SSW switched off, install the module on the XC44 connector. Make sure it is fitted in correctly and

secured by the screws.

 Apply power to the SSW.

 Observe the content of the parameter P0723. Verify whether the module has been recognized. The

detection occurs automatically and does not require any user intervention. The module MS LED must be on

in solid green. During the module acknowledgement phase a warning message will be showed on the

product HMI.

 Set the SSW network address through the parameter P0725.

- Valid values: 0 to 63.

 Adjust the baud rate at P0726:

- 0 = 125 kbps;

- 1 = 250 kbps;

- 2 = 500 kbps;

- 3 = Autobaud.

 The number of words to be exchanged with the network master is defined automatically (refer to the section

4.2). The default is 1 input and 1 output word. The same number of words must be adjusted at the

DeviceNet Master.

 Cycle the SSW auxiliary power supply, so that the changes become effective.

 Connect the network cable to the module.

 Register the configuration file (EDS file) in the network configuration software

 Add the SSW to the scan list of the master.

 Choose a method for data exchange with the master in the network configuration software, i.e., polled,

change of state, cyclic or bit-strobe. The SSW DeviceNet module supports all those types of I/O data,

besides of the explicit (acyclic data).

 If everything is configured correctly, the NS LED will go on in solid green. It is in that condition that the cyclic

data exchange between the SSW and the network master effectively occurs.

For more information regarding the mentioned parameters, refer to the section

2.1.6 Access to the Parameters

After the EDS file registration in the network configuration software, the user will get access to the equipment

complete parameter list, which can be accessed via explicit messages.

For details on the use of this resource, refer to the PLC programming software documentation.

2.2 PROFIBUS DP-V1

2.2.1 PROFIBUS-05 Kit

2.2.3 Indications

 ST LED: bicolor LED (green/red). It indicates the communication module status.

 OP LED: bicolor LED (green/red). It indicates the operation mode status.

For a better interpretation of the indications above, refer to the sections

6.7 and 6.8.

2.2.4 Connection to the Network

For the SSW connection using the Profibus active interface, the following points must be observed:

 It is recommended to use a shielded cable with a twisted pair of wires, preferable one specific for Profibus.

The connector must also be compatible with the Profibus specification.

 The cable must be laid separately (and far away if possible) from the power cables.

 All the network devices must be properly grounded, if possible at the same point. The cable shield must

also be connected to the protective ground. The Profibus connector normally has a point for connecting the

cable shield.

 Termination resistors must be installed only at the extremes of the main bus, even if there are derivations.

Switches for enabling those resistors are normally present at the Profibus connector.

2.2.5 Module Configuration

In order to configure the Profibus DP-V1 module follow the steps indicated below:

 With the SSW switched off, install the module on the XC44 connector. Make sure it is fitted in correctly and

secured by the screws.

 Apply power to the SSW.

 Observe the content of the parameter P0723. Verify if the module was recognized. The detection occurs

automatically and does not require any intervention from the user. The ST LED from the module must be on

in solid green. During the module acknowledgement phase a warning message will be showed on the

product HMI.

 Set the SSW network address by means of the parameter P0725.

- Valid values: 1 to 126.

 It is not necessary to set the module baud rate. Profibus uses autobaud; therefore, this configuration is

done by means of the network master.

The SSW7000 requires the use of a 180 º connector.

SSW7000| 11

Accessory Kits (active modules)

 The number of words to be exchanged with the network master is defined automatically (refer to the section

4.2). The default is 1 input and 1 output word. The same number of words must be adjusted at the Profibus

Master.

 Cycle the SSW auxiliary power supply, so that the changes become effective.

 Register the configuration file (GSD file) in the network configuration software

 Add the SSW to the device list of the master, setting the number of words according to the programmed in

the SSW.

 Connect the network cable. If everything is configured correctly, the module OP LED will go on in solid

green. It is in that condition that the cyclic data exchange between the SSW and the network master

effectively occurs.

For more information regarding the mentioned parameters, refer to the section

2.2.6 Access to the Parameters

The PROFIBUS-05 communication kit allows parameter reading/writing services by means of DP-V1 acyclic

functions. The parameter mapping is done based on the slot and index addressing, as showed in the equations

below:

 Slot: (parameter number - 1) / 255

 Index: (parameter number - 1) MOD 255

NOTE: MOD represents the remainder of the division.

2.3 ETHERNET/IP

2.3.1 Kit ETHERNETIP-05

 WEG part number: 10509967.

 It is composed by the Anybus ABCC-EIP communication

module, mounting instructions and a torx screwdriver for fixing

the module.

 Standard RJ45 connector.

 ODVA certified interface.

 It allows access (reading/writing) to certain parameters via WEB.

2.3.2 Connector

The EtherNet/IP communication module has a common female RJ45 connector. The same mounting standard

(T-568A or T-568B) used in cables for office networks can also be adopted for the industrial environment.

However, the drive installation site must be verified. Cables and connectors normally used in office networks use

to be fragile. They cannot withstand high temperatures, high mechanic stress, excessive vibration and do not

have a high protection degree. The responsible for the plant installation must evaluate those factors and suggest

adaptations according to the needs.

2.3.3 Indications

 MS LED: bicolor LED (green/red). It indicates the communication module status.

 NS LED: bicolor LED (green/red). It indicates the EtherNet/IP network status.

 LINK LED: green LED. It indicates connection (link) and also activity in the network.

For a better interpretation of the indications above, refer to the sections

7.6, 7.7 and 7.8.

The SSW7000 with Profibus DP-V1 communication module will be recognized by the network configuration software as Anybus-CC

Profibus DP-V1.

SSW7000| 12

Accessory Kits (active modules)

2.3.4 Connection to the Network

For the connection of the SSW using the active EtherNet/IP interface, the following points must be observed:

 The SSW must be connected to an EtherNet/IP network preferably by means of switches. Hubs are not

recommended because they do not use the channel in an efficient way (great number of collisions).

 The most common topology is in star, exactly the way it is done with computer networks.

 It is recommended to use equipment (cables, switches) prepared for industrial environment.

 Each cable segment (switch ⇔ SSW) with a maximum length of 90 m.

2.3.5 Module Configuration

In order to configure the EtherNet/IP module follow the steps indicated below:

 With the SSW switched off, install the module on the XC44 connector. Make sure it is fitted in correctly and

secured by the screws.

 Apply power to the SSW.

 Observe the content of the parameter P0723. Verify whether the module has been recognized. The

detection occurs automatically and does not require any user intervention.

The MS and NS LEDs from the

module must be flashing in green

 Connect a network cable to the module. The other extreme of the cable must be connected to a hub/switch

or, occasionally a PC (for the PC ⇔ SSW connection use a cross-over cable). If the network cable is

installed correctly, the LINK LED will go on in solid green indicating that a successful connection occurred. If

this does not occur, make sure the cable is in good conditions and the hub/switch is on.

 With the aid of a PC connected to the same network where the SSW with the EtherNet/IP is present,

execute the HMS AnyBus IPconfig

program. This software will scan the network for the module. In the

example below a module with the IP 192.168.0.4 was found.

 In order to change those configurations, double-click the module IP address. The window below will be

displayed. Set those parameters according to the network where the SSW will be installed. Remember that

the IP address is unique, i.e., each equipment in the network has its own address. The IP duplicity is a

critical fault and causes serious communication problems among the devices.

The SSW7000 with EtherNet/IP communication module will be recognized by the network configuration software as Anybus-CC

EtherNet/IP.

It is available on the CD-ROM that comes with the SSW.

SSW7000| 13

Accessory Kits (active modules)

 The number of words to be exchanged with the network master is defined automatically (refer to the section

4.2). The default is 1 input and 1 output word. The same number of words must be adjusted at the

EtherNet/IP Master.

 Connect the network cable to the module.

 Register the configuration file (EDS file) in the network configuration software.

 If everything is configured correctly, the NS LED will go on in solid green and the LINK LED will start blinking

indicating normal network activity.

For more information regarding the mentioned parameters, refer to the section

2.3.6 Baud Rate

The SSW with EtherNet/IP kit works in networks with 10 Mbps or 100 Mps rates, in half-duplex or full-duplex

mode. When working at 100 Mbps full-duplex, the effective baud rate doubles, changing to 200 Mbps. The

baud rate setting is done only via software, as illustrated below:

 In order to perform such setting, it is necessary to have a PC with an Internet browser connected to the

same network (same IP addressing range) of the SSW.

 Open the browser and type the hostname or the IP address of the SSW. In the example below, we use the

IP 192.168.0.4.

 Click on ‘Network interface’. A window with information about the communication module will be displayed.

SSW7000| 14

Accessory Kits (active modules)

 Next, click on ‘Network Configuration’. In order to set the baud rate select the option ‘Comm Settings’.

 Save the modifications clicking on the ‘Store Settings’ button.

2.3.7 Access to the Parameters via WEB

The SSW allows access for reading and writing via web certain parameters previously programmed by the user

(refer to the section

7). This function allows the operator to monitor the SSW status, being necessary only a

computer with access to the industrial plant network.

In order to use this function follow the steps indicated below:

 Make sure the SSW is online. Verify the Anybus communication status via the parameter P0724.

 Again, it is necessary to have a PC with an Internet Browser connected to the same network (same IP

addressing range) of the SSW.

 Open the browser and type the hostname or the IP address of the SSW. In this example, the SSW has the

IP 192.168.0.4. The window showed in the figure 2.1 will be displayed.

 Click on ‘Parameter data’. Another window containing the reading and writing parameters will be showed.

In this case, one reading parameter (SSW Status Word) and one writing parameter (Anybus-CC Control

Word) are showed. This window will show all the parameters programmed by the user.

SSW7000| 15

Important: The parameter writing via WEB (acyclic) is performed in a way similar to the I/O data (cyclic). Thus, if

a specific variable is accessible via cyclic as well as acyclic connections, one will be overwritten by the other. In

the case above, writing in the ‘Anybus-CC Control Word” will be almost immediately overwritten by the value

sent via the I/O cyclic connection. The same happens with the next word. In this case one gets the wrong

impression that the command had not been executed.

SSW7000| 16

Accessory Kits (passive modules)

3 ACCESSORY KITS (PASSIVE MODULES)

In order to make available a RS232 or a RS485/422 interface at the SSW, one of the communication kits

described next can be used. The operation of those modules follows the same principle of the serial interface.

For this reason it is not possible to use them simultaneously with the RS485-01, RS232-01 and CAN/RS485-01

communication kits. If this occurs, the A130 alarm message will be showed on the HMI to indicate hardware

incompatibility.

Those passive devices work only as physical layer converters, not performing any processing over the data flow.

This means that any serial protocol programmed in P0312 (Modbus-RTU, TP) can be used with those

interfaces.

For more information on the operation of those passive modules, refer to the SSW7000 Modbus-RTU User’s

Manual. Instructions on the installation of those modules can be obtained in the guide that comes with the kit.

3.1 RS232

3.2 RS232-05 KIT

 WEG part number: 10413656.

 It is composed by the Anybus ABCC-RS232 communication

module (drawing at the left), mounting instructions and a torx

screwdriver for fixing the module

 It allows baud rates up to 115.2 kbps.

3.3.2 Connection to the Network

For the connection of the SSW using the passive RS232 interface, the following points must be observed:

 Use good quality cables, preferably shielded.

 Keep the cable length within the limits stipulated by the standard, normally about 10 m.

 Avoid passing the cables close to output and input power cables.

3.4 RS485/422

3.4.1 RS485-05 Kit

 WEG part number: 10413657.

 It is composed by the Anybus ABCC-RS485 communication

module (drawing at the left), mounting instructions and a torx

screwdriver for fixing the module

 It allows baud rates up to 115.2 kbps.

3.4.2 Connector Pinout

The RS485/422 interface module presents a female DB9 connector with the following pinout:

3.4.3 Indications

 PWR LED: Green LED. When on, it indicates that the module is powered.

3.4.4 Connection to the Network

For the connection of the SSW using the passive RS485 interface, the following points must be observed:

 Use good quality shielded cables.

 Keep the cable length within the limits stipulated by the standard, normally about 1000 m.

 Even being the RS485 more robust than the RS232 because of its cables using signals in differential mode

(balanced signals), avoid passing them close to power cables.

 Put termination resistors between the data signal wires (RxD/TxD and TxD/RxD) at the network extreme

nodes. This will avoid reflections in the line.

SSW Parameter Settings

4 SSW PARAMETER SETTINGS

Next, only the SSW parameters related to the Anybus-CC communication will be presented.

4.1 SYMBOLS FOR PROPERTIES DESCRIPTION

Read-only parameter.

CFG

Parameter that can be changed only with a stopped motor.

Net

Parameter visible on the HMI if the SSW has a network interface installed – RS232,

RS485, CAN, Anybus-CC, Profibus – or if the USB interface is connected.

Serial

Serial Parameters visible on the HMI if the SSW has the RS232 or the RS485 interface

installed.

USB

Parameters visible on the HMI if the SSW USB interface is connected.

Anybus

Parameters visible on the HMI if the Anybus-CC module is connected.

P0220 – LOCAL/REMOTE Mode Selection

P0229 – LOCAL Command Selection

P0230 – REMOTE Command Selection

These parameters are used for the configuration of the SSW local and remote mode command sources. In

order that the SSW is controlled through the Anybus-CC interface, one of the ‘Anybus-CC’ options available in

the parameters must be selected.

The detailed description of these parameters is found in the Soft-Starter SSW7000 Programming Manual.

P0313 – Communication Error Action

Adjustable 0 = Off Factory setting: 0

Range: 1 = Ramp Stop

2 = General Disable

3 = Goes to Local

4 = Off

5 = Causes Fault

Properties: CFG, Net

Access groups via HMI: 01 PARAMETER GROUPS...

∟ 33 Communication... ... ... . ..

∟ 131 RS232/485 Serial... ... ...

Description:

It allows programming the action the SSW must take if a communication error is detected.

Table 4.1: Parameter P0313 options

Options Description

0 = Off No action is taken and the SSW remains in the existing

status.

1 Ramp Stop A stop command with deceleration ramp is executed and

the motor stops according to the programmed deceleration

ramp.

2 = General Disable The SSW is General Disabled and the motor coasts to stop.

3 = Goes to Local The SSW is commanded to the local mode.

0 = Off No action is taken and the SSW remains in the existing

status.

5 = Causes Fault Instead of an alarm, a communication error causes a SSW

fault, and it is necessary to perform a fault reset in order to

restore the normal operation.

SSW Parameter Settings

For the Anybus-CC interface, the events of Anybus-CC module offline (A129 alarm/F229 fault) and Anybus-CC

module access error (A130 alarm/F230 fault) are considered communication errors.

The actions described in this parameter are executed by means of the automatic writing of the respective bits in

the Anybus-CC control word – P0686. In order to be effective, it is necessary that the SSW be programmed to

be controlled via Anybus. This programming is done by means of the parameters P0220, P0229 and P0230.
