1. Introduction

1.1 Overview of Fieldbus I/O

The Fieldbus I/O option is an integrated I/O system that supports DeviceNet, PROFIBUS DP, and EtherNet/IP fieldbuses.

A fieldbus is a standard of signal communications between field devices operating in a factory (sensor, actuator, robot controller, etc.) and controller (PLC or robot controller) using serial communications. Compared to signal communications using analog signals, a fieldbus has the following features:

• Access to signals from multiple devices and multiple data from each device using one cable.

1. Introduction

• Precise signal transmission since there is no need for A/D conversion and D/A conversion.

• Less wiring costs, including signal relay board costs and installation area due to several dozen (or a hundred) devices connected on one fieldbus.

• More flexible modification and expansion of a system because multiple devices are simply added to one fieldbus without additional wiring.

• Slave devices can transmit self-diagnostics information.

For each fieldbus on the RCxxx controller, there is at least one board installed. You can use more that one fieldbus type on the same controller. You can also use multiple boards for the same fieldbus type. The EPSON RC+ software key Fieldbus I/O Option must be enabled to use this option.

Fieldbus I/O Rev.6 1

Response times for Fieldbus I/O can vary and depend on several factors, including baud rate, scan rate, number and types of devices, number of SPEL+ tasks, etc. When the fastest and most consistent response times are required, please use EPSON standard digital I/O, which incorporates interrupt driven inputs and outputs.

1. Introduction

1.2 DeviceNet

Overview of DeviceNet

DeviceNet is a fieldbus network that provides easy interconnection between control devices (PLC, PC, sensor, actuator, etc.).

DeviceNet was developed by Allen-Bradley as an open communication standard to connect various field devices (sensor, actuator, robot controller, etc.). Because of the open communication standard, DeviceNet users can easily construct a multi-vendor system with various devices developed around the world.

Features of DeviceNet

Reduced Wiring

Compared with parallel wiring, DeviceNet employs a dedicated 5-wire cable (signal wires and power wires) which substantially reduces the number of necessary wires, wiring time and cost.

Detachable communication connectors provide you with simple wiring between nodes and easy network separation or reconstruction.

Specified environment-resistance cables allow you to construct an environment-resistant system at low cost.

Open Standard (Multi-vendor)

Due to an open communication standard, various devices from many manufacturers are available. Standardized communication connectors provide you with easy network construction.

The maintenance spare parts stored on site (factory, etc.) can be reduced because different manufacturers’ devices are used in case of a breakdown. Similar products are available around the world due to a global standard DeviceNet.

Large Numbers of Inputs/Outputs

For EPSON RC+ standard I/O and expansion I/O, the number of inputs/outputs is limited to 512 inputs and 512 outputs. When configuring a device to be a master of fieldbus I/O, you can control more than 16,000 total inputs and outputs. For a slave device, 2,040 inputs (255 bytes) and 2,040 outputs (255 bytes) are available.

2 Fieldbus I/O Rev.6

1. Introduction

Different Connection Types

There are two messaging connections: I/O messaging connection and explicit messaging connection. The I/O messaging connection includes polling, strobe, cyclic, and change of state. I/O messaging connections are explained below:

Polling: First, a master device sends output data to a slave device and then the slave device

responds. Data is normally exchanged in every communication cycle. The communication frequency can be changed by setting. This connection type is the most often used.

Strobe: First, a master device requests slave devices to send data with multicast messages,

and then, each slave device responds separately. Data from many sensors on the system can be effectively gathered. When the master does not receive responses from all requested slave devices, a timeout error occurs.

Change Of State:

A device sends data whenever it changes. Signals for device diagnosis are sent regularly in the background. This connection type is useful for remedying DeviceNet communication traffic.

Cyclic: A slave device transfers data regularly according to its internal timer. This

connection type is typically used for communicating with a temperature controller. The data transfer frequency is defined by master configuration.

NOTE

)

For Change of State and Cyclic, you can disable the ACK that is for verifying that communication is completed. Never disable ACK, since communication errors cannot be detected.

Functions of Master

The Master device gathers and controls all nodes on one network.

A DeviceNet master can control up to 64 nodes (max. 2 kbytes) on one network.

A PLC is typically configured as a master and controls all nodes in factory automation system, but EPSON RC+ is also capable of being a master.

DeviceNet network configuration is specified by configuration management software. This software is normally provided by a master device manufacturer. The configuration management software determines parameters for each slave device via an Electronic Data Sheet (EDS).

Available connection types are Polling, Strove, Cyclic, Change Of State, and explicit messaging.

Available baud rates are 125 kbps, 250 kbps, and 500 kbps.

Functions of Slave

A slave can exchange data with a master device.

The configuration management software identifies parameters of each slave device via Electronic Data Sheet (EDS) where the parameters are registered.

Available connection types are Polling, Strobe, Cyclic, and Change of State.

Available baud rates are 125 kbps, 250 kbps, and 500 kbps.

DeviceNet supplies 24V DC communications power to each node via 5-wire cables. You can install the communications power supply at any location on the DeviceNet network. We recommend providing a dedicated communications power supply on the network separately even though it is possible to share power among the communications power supply, node internal circuit power supply, and I/O power supply.

Shield Ground of Signal Wire

Ground the DeviceNet network at one point with 100 Ω or less. As a noise countermeasure, you can leave the network ungrounded. For details, refer to the 4. Troubleshooting.

Station

There are four types of stations (devices): master, slave, repeater, and configurator.

The master controls a network and gathers its slaves.

The slave, including external I/O and other devices, outputs data as a response to a master’s output order and informs the master of its input status.

The repeater is necessary for a network with more than 32 slaves to separate network segments.

The configurator, used only for network installation, configures a scan list of the slaves on the master device.

You can install masters anywhere on the network. You can connect up to 126 stations including server and repeater on your network. However, we recommend you to use one device for the engineering device.

Network Cable

The PROFIBUS cable can be used as a network cable. There are four types (A, B, C, D) of PROFIBUS cables. Normally, cable type A is used for a PROFIBUS DP network. The cable type A specifications are shown in the table below.

Fieldbus I/O Rev.6 67

2. Installation

68 Fieldbus I/O Rev.6

3. Operation

This chapter contains information on how to use the Fieldbus I/O option after it has been installed.

3. Operation

3.1 Fieldbus I/O Addressing in SPEL

Each of the Fieldbus I/O commands in SPEL+ refer to one device on the network. The bit number and port number parameters refer to inputs and outputs local to the device.

3.2 SPEL+ Fieldbus I/O Commands

All Fieldbus I/O commands begin with the same prefix: "FbusIO_". Here are the main commands. For details, please see the online help or SPEL

FbusIO_GetBusStatus Returns the status of the specified fieldbus.

FbusIO_GetDeviceStatus Returns the status of the specified fieldbus device.

FbusIO_In Returns the status of an 8 bit input port.

FbusIO_InW Returns the status of a 16 bit input port.

FbusIO_IONumber Returns the bit number of the specified Fieldbus I/O label.

FbusIO_Off Turns an output off.

FbusIO_On Turns an output on.

FbusIO_Out Simultaneously sets 8 output bits.

FbusIO_OutW Simultaneously sets 16 output bits.

FbusIO_Sw Returns the status of one input bit.

Language Reference Manual.

FbusIO_SendMsg Sends an explicit message to a device and returns the reply.

NOTE

)

Fieldbus I/O Rev.6 69

Response times for Fieldbus I/O can vary and depend on several factors, including baud rate, scan rate, number and types of devices, number of SPEL+ tasks, communication error, etc. When the fastest and most consistent response times are required, please use EPSON Standard digital I/O, which incorporates interrupt driven inputs and outputs.

3. Operation

3.3 Outputs Off by Emergency Stop and Reset Instruction

You can configure the system so that all outputs including the fieldbus outputs will be turned off when the emergency stop occurs and when a Reset instruction is executed. For details of the configuration, refer to the chapter SPEL+ Options in the EPSON RC+ User's Guide.

NOTE

)

A command that was issued just before an emergency stop can be executed after the emergency stop condition is cleared. If the outputs from the fieldbus involve risk, the “Outputs off during Emergency Stop” option should be enabled to remove all power to output devices when an emergency stop occurs.

3.4 Waiting for Input or Output Status

The SPEL+ Wait statement cannot be used for Fieldbus I/O. You can make your own function to handle this.

For example:

Function WaitFbusInput(bus As Integer, device As Integer, bit As Integer, state As Integer)

Do If FbusIO_Sw(bus, device, bit) = state Then Exit Function EndIf Wait .01 Loop

Fend

In the program example above, a Wait statement is used to prevent the task from using too much CPU. You can remove the Wait for faster response, but the task will use more CPU. You may also want to add a timeout or other checks.

70 Fieldbus I/O Rev.6

3.5 Using FbusIO_SendMsg

FbusIO_SendMsg is used to send an explicit message to a device and return a reply. This command operates according to the protocol.

The syntax is as follows:

FbusIO_SendMsg bus, device, msgParam, sendBytes(), recvBytes()

There are two arrays passed to the function. The sendData array contains the data that is sent to the device in bytes. This array must be dimensioned to the correct number of bytes to send. If there are no bytes to send, you must use 0 as the parameter. The recvData array returns the response in bytes. This array is automatically re-dimensioned to the number of bytes received.

For DeviceNet, you need to initialize the sendData array with the command, class, instance, and attribute, as shown in the example below. Consult the documentation that came with the device for the values that can be used. The msgParam parameter value is always 0 for DeviceNet messages.

Here is an example for DeviceNet, EtherNet/IP:

' Send explicit message to the device Byte sendData(5) Byte recvData(10) Integer i sendData(0) = 14 ' Command sendData(1) = 1 ' Class sendData(3) = 1 ' Instance sendData(5) = 7 ' Attribute FbusIO_SendMsg 1, 1, 0, sendData(), recvData() For i = 0 To UBound(recvData) Print recvData(i) Next i

3. Operation

For PROFIBUS DP, you need to specify the service number in the msgParam parameter. Consult the documentation that came with the device for the services that are supported. Some services require 0 send bytes. In this case, use 0 for the sendBytes parameter.

Here is an example for PROFIBUS DP:

' Send message to Profibus device Byte recvData(10) Integer i ' Service 56 - read all inputs ' sendBytes = 0 FbusIO_SendMsg 2, 1, 56, 0, recvData() For i = 0 To UBound(recvData) Print recvData(i) Next i

Fieldbus I/O Rev.6 71

3. Operation

3.6 Using Slave Mode

In slave mode, the EPSON RC+ system is a slave on the bus. Outputs from the master are inputs in EPSON RC+, and inputs to the master are outputs in EPSON RC+.

Uses for slave mode:

• External equipment can monitor data in the controller

• Remote control

To use the system in slave mode, perform the following basic steps:

1. Configure local slave on the Fieldbus scanner board. Refer to the 2. Installation for instructions for the type of hardware you are using.

2. Design your application to handle requests from the Fieldbus master and return data or execute functions.

3.7 Remote Control Slave

If the controller will be remotely controlled by a Fieldbus master, your application must auto start and run in a continuous loop to service requests from the master. Use OnErr, Trap Error, Trap Emergency and Restart to accomplish this. Refer to the sample project for Fieldbus remote slave called FieldbusRemoteSlave that is included with EPSON RC+.
