Bridging Across Networks

Device 1

Logix5000™ devices can usually communicate with devices on other networks with no additional configuration or programming.

• A bridge connects two different networks. The bridge is either:

– single device with communication ports for two different

networks

– separate communication devices in the same chassis

• For example, the bridge device shown below is connected to

both EtherNet/IP and DeviceNet networks. Device 1 on EtherNet/IP can communicate with Device 2 on DeviceNet through the bridge.

Choose a Baud Rate for the

The default baud rate for a DeviceNet network is 125K bits/s. This is the easiest baud rate to use and is usually sufficient.

Network

The 2 most common methods to set the baud rate of a device are:

Method: Description:

autobaud feature At power up, the device automatically sets its baud rate to the baud rate of the first device it hears on the network. It

remains set until the device powers up again.

The network requires at least one device with a fixed baud rate so the autobaud devices have something against which to set. Typically, scanners and network interfaces have a fixed baud rate.

switches or pushbutton on the device

software Some devices require a programming device to set its address. For example, you can use your computer and the

Some devices have switches or a pushbutton that set the baud rate.

• The device reads the switch setting at power up.

• Typically, the switch lets you select either:

• autobaud

• fixed baud rate of 125K, 250K, or 500K

• If you change the switch setting, you have to cycle power to the device before the change to takes effect.

There are exceptions. For example, the 1756-DNB module has a pushbutton, which only lets you set the baud rate if the module is unconnected from the network or network power is off. Once you change the baud rate, the module automatically resets to the new baud rate.

DeviceNet Node Commissioning tool (software) to set the baud rate of a device. The Node Commissioning tool is available:

• automatically when you install RSNetWorx for DeviceNet software

• as a separate application on the RSLogix 5000 software CD, revision 13.0 or later

Publication DNET-UM004A-EN-P - March 2004

1-10 Before You Begin

If You Want to Use a Higher Baud Rate…

The length of the trunkline and type of cable determines which baud rates you can use:

Baud rate Maximum distance Cumulative drop line

flat cable thick cable thin cable

125K bit/s 420m (1378 ft) 500m (1640 ft) 100m (328 ft) 156 m (512 ft)

250K bit/s 200m (656 ft) 250m (820 ft) 100m (328 ft) 78m (256 ft)

500K bit/s 75m (246 ft) 100m (328 ft) 100m (328 ft) 39m (128 ft)

If you change the baud rate of your network, make sure that all devices change to the new baud rate. Mixed baud rates produce communication errors.

To set the baud rate for the network:

length

1. Connect the network interface to the network and set its baud rate.

2. Connect the scanner to the network and set its baud rate.

3. For each device that has only fixed baud rates (no autobaud),

set the baud rate and connect it to the network.

4. Connect the remaining devices to the network and enable autobaud for each of them.

If a device: Then:

has a switch to enable autobaud

does not have a switch to enable autobaud

A. Set the switch to autobaud.

B. Connect the device to the network.

Calculate Scanner Memory Requirements

If a device sends input data, it uses input memory in the scanner.

device device device

If a device gets output data, it uses output memory in the scanner.

A Logix5000 scanner has fixed sections of memory for the input and output data of your network. Each device on your network requires either some input or output memory of the scanner. Some devices both send and receive data, so they need both input and output memory.

The memory of a Logix5000 scanner is organized as an array

of DINTs (4-byte elements). A Logix5000 system is easier to program if you give each device its own DINT or DINTs within the scanner.

DINT

Some memory may be left empty (not used).

Device B

The data fills only the portion of memory that it needs.

Device A

To make sure your network is within limits, calculate the amount of input and output memory that the scanner needs. This information will also be very useful when you configure the scanner.

Check the I/O Limits of the Scanner

Once you tally the input and output data for your network, make sure it is within the limits of the scanner. If they exceed the limits, use multiple scanners.

• Some devices have no switches or pushbutton to set the address. They require

software such as RSNetWorx for DeviceNet software to change the address. This means that you must first place it on the network at its preset address of 63 before you can change the address.

• If another device is already using address 63, there will be an address conflict

and you won’t be able to communicate with the newly connected device.

• Leaving address 63 open makes it possible to configure a new device.

• The auto-address recovery feature also requires address 63 to be open.

Determine If You Can Use AutoScan

This chapter provides a quick method for configuring a DeviceNet network. It uses the AutoScan feature to establish communication between the controller and your devices with minimal steps.

To use the AutoScan feature to configure your network:

Step: Page:

❑ Determine If You Can Use AutoScan 4-1

❑ Review How AutoScan Effects Your Network 4-2

❑ Install the Node Commissioning Tool 4-2

❑ Connect Each Device to the Network 4-3

❑ Turn On AutoScan 4-7

❑ Access Device Data 4-9

❑ Put the Scanner in Run Mode 4-11

❑ Additional Information About AutoScan 4-12

To use this chapter, make sure your network meets the following requirements:

Each device on your DeviceNet network (except the scanner):

• sends ≤ 4 bytes of input data

• gets ≤ 4 bytes of output data

You have one of the following DeviceNet scanners:

• ControlLogix 1756-DNB

• FlexLogix 1788-DNBO

Your scanner has the following firmware revision:

This scanner: Requires this firmware:

ControlLogix 1756-DNB revision 5.0 or greater

FlexLogix 1788-DNBO revision 3.0 or greater

How AutoScan Effects Your

As you use AutoScan, keep the following in mind:

Network

Consideration: Description:

1. AutoScan clears the current configuration.

2. AutoScan allocates a fixed memory size for each device.

The actual data for the device fills the portion

that it needs and the rest remains unused.

3. New devices are automatically available.

4. The Automatic Device Recovery (ADR) option is not available.

With AutoScan, the scanner automatically sets up communication with the devices on your DeviceNet network. When you turn on the AutoScan option, the scanner removes any previous configuration that was done to the scanner.

At its default setting, AutoScan allocates 1 DINT of input memory and 1 DINT of output memory for each device on the DeviceNet network.

While the scanner is in idle mode, AutoScan continues to establish communication with devices that you connect to the network (as long as the device uses ≤ 4 bytes of input data and ≤ 4 bytes of output data).

To use the Automatic Device Recovery (ADR) option of a DeviceNet scanner, you have to use RSNetWorx software to edit the configuration of the scanner. This turns off AutoScan.

address 63. Leaving address 63 open lets you get a new device on the network without conflicting with another device.

• Scanners and network interface devices use a fixed baud rate.

• Sensors and similar DeviceNet devices use autobaud to set their baud rate. They

wait for another device to communicate. Then they set their baud rate to the same baud rate as the other device.

• By first placing a scanner or network interface on the network, the other device

have a baud rate against which to set their baud rate.

• Initially, leave the baud rate of the scanner and network interface at the default

setting of 125K bits/s. If you want to change the baud rate, wait until after you establish communication with all your devices at the default setting (125K).

• To set the DeviceNet address of the scanner, see Set the Address of a Scanner on

page 4-4.

• Out of the box, a DeviceNet device is preset for address 63. To avoid address

conflicts, connect and set the devices one at a time. Otherwise the address conflicts may prevent communication with them.

• If a device has a switch to set its baud rate, set the switch to autobaud, if available.

Otherwise, set the device to the baud rate of the network.

• After you change the address or baud rate of a device via a switch, cycle power to

the device.

• If a device has no switch or pushbutton for its address or baud rate, see Set the

Address and Baud Rate of a Device Via Software on page 4-5.

• After you set the address of a device, check its network status indicator. Typically, a

Additional Information About AutoScan

Type of Connection that the Scanner Sets Up

The type of update (connection) that the scanner sets up with each device depends on the device. The scanner chooses the first connection type that the device supports in this order:

1. change-of-state (COS)

2. polled

3. strobed

4. cyclic at 1000 ms

The scanner tries to set up a change-of-state connection. If the device doesn’t support change-of-state, then the scanner tries to set up a polled connection, etc. The type of connection that the scanner sets up may not be the default for the device.

Allocating More Memory for Each Device

The AutoScan feature is easiest to use if you leave it set to 1 DINT (4 bytes) of input memory and output memory for each address.

number of bytes of input memory and output

memory to allocate in for each address

As an option, you can allocate more memory for each device.

Publication DNET-UM004A-EN-P - March 2004

Consideration: Description:

Automatically Configure a DeviceNet Network 4-13

1. The bytes/node value defines how much memory for each address.

For example, if you specify 2 DINTs (8 bytes)

per address, the scanner sets aside 2 DINTs

The actual data for the device fills the portion

that it needs and the rest remains unused.

2. The scanner sets-up communication with any device that fits within the allocated memory size.

3. The scanner skips devices that are too large.

AutoScan lets you specify how much input and output memory to give to each address on your network.

DINT Input Memory

for each address.

device at address 0

device at address 1

device at address 2

The scanner automatically sets up communication with those devices that fit within the memory allocated for each address.

• For example, if you allocate 2 DINTs (8 bytes) per address, the scanner sets up

communication with any device that sends or receives 1 - 8 bytes of data.

• The scanner adds as many device as it can until it runs out of memory.

• If you give too much memory to each address, you may not have enough memory for

all your devices.

If a device needs more memory than is allocated, the scanner skips it and does not set up communication with it.

For example, if you specify 2 DINTs (8 bytes) per address but a device sends 9 bytes, the scanner does not add the device to the scan list.

4. Manually editing the scan list turns off AutoScan.

If you use RSNetWorx software to edit the configuration of the scanner, the scanner turns off AutoScan. Do not turn it back on or you will clear the configuration that you just entered.

For example, if you use RSNetWorx software to manually add a device to the scan list, the scanner turns off AutoScan. If turn on AutoScan again, the scanner clears it current configuration and starts over.

Set the Address of a Device

A DeviceNet device uses at least one of the following methods to set its address on the network:

Method: Description:

switches If a device has switches or another hardware mechanism to set

its network address, use that mechanism. Keep in mind that a device typically reads the switches on power up. If you change the address, you usually have to cycle power to the device.

Some switches also let you set the address of the device via software such as RSNetWorx.

pushbutton Some devices have a pushbutton that lets you cycle through

If You Need to Conserve EtherNet/IP or ControlNet Network Bandwidth

The default configuration of the scanner gives you the maximum amount of input, output, and status data.

If the scanner communicates with the controller via an EtherNet/IP or ControlNet network and you need to conserve bandwidth over that network, consider reducing the input, output, or status sizes.

• Set the input and output sizes = the number of input and output

DINTs in the scanner that actually store device data.

• If you are not going to use all the status information, set the

status size to the minimum required. See Table 7.1 on page 7-4.

EXAMPLE

Set the status size for a scanner

• If you want to only use the ASCII representation

of scanner status/display, then set the Status Size = 10.

• If you also want to read the status code of the
