Chapter

Before You Begin

This chapter provides an overview of communication between the 1753-DNSI and the GuardPLC controller. Before configuring your 1753-DNSI module, you must understand:

• the safety concept of the system

• the data exchange between the GuardPLC controller and

DeviceNet devices through the 1753-DNSI module

• the roles of RSNetWorx for DeviceNet and RSLogix Guard PLUS! software in the safety system

• the features of the DeviceNet Safety Scanner

• the physical layout of your network

Safety Concept

The DeviceNet Safety Scanner for GuardPLC Controllers is certified for use in GuardPLC safety applications up to and including Safety Integrity Level (SIL) 3, according to IEC 61508, and Category (CAT) 4, according to EN 954-1, in which the de-energized state is the safety state.

IMPORTANT

The DeviceNet Safety Scanner and the GuardPLC system use the following mechanisms to support the integrity of the data they exchange:

• Safety Network Number – A unique number that identifies the Safety Network. Each DeviceNet sub-network that contains safety nodes must have one unique Safety Network Number.

• Configuration Signature – The combination of an ID number, date, and time that uniquely identifies a specific configuration for a safety device.

For SIL 3 and CAT 4 safety system requirements, including proof test intervals, system reaction time, and PFD/PFH calculations, refer to the GuardPLC Controller Systems Safety Reference Manual, publication number 1753-RM002. You must read, understand, and fulfill these requirements prior to operating a GuardPLC controller-based SIL 3 or CAT 4 safety system.

1 Publication 1753-UM002A-EN-P - July 2005

1-2 Before You Begin

• HSP (High-speed Safety Protocol) Signature – This is a read-only value that represents the data exchanged between the GuardPLC controller and the safety scanner. The HSP Signature is calculated based on the Scanner Configuration Signature and changes only when the data exchanged by the controller and the safety scanner changes. The HSP Signature is sent to the controller configuration software and helps ensure the integrity of the data.

• Controller ID (SRS) – A unique identifier for every GuardPLC controller and GuardPLC Ethernet Distributed I/O module in a system, the Controller ID must be a unique number from 1 to 65,535. The default is 60000.

• Safety-Lock – The safety scanner and DeviceNet safety I/O modules must be Safety-Locked to prevent their configurations from being unintentionally modified. Safety-Lock all DeviceNet Safety devices by running the Safety Device Verification Wizard in RSNetWorx for DeviceNet before placing the safety application into service.

• Password protection – The configuration of the safety scanner can be protected by the use of an optional password. If you set a password in a safety device, the download, Safety-Reset, Safety-Lock and Safety-Unlock operations will require a password.

DeviceNet Safety Scanner Communications

The 1753-DNSI provides DeviceNet access for GuardPLC 1600 and GuardPLC 1800 controllers. These GuardPLC controllers support communications via High-Speed Safety Protocol (HSP). The 1753-DNSI reads and writes data from DeviceNet nodes and exchanges this aggregate data with the GuardPLC controller via HSP.

The 1753-DNSI scanner communicates with DeviceNet devices over the network to:

• read inputs from a device

• write outputs to a device

• monitor device status

How the 1753-DNSI Communicates

For standard data, the safety scanner communicates with a device via strobe, poll, change of state, and/or cyclic messages. It uses these messages to solicit data from or deliver data to each device in its scanlist.

Publication 1753-UM002A-EN-P - July 2005

Before You Begin 1-3

For safety data, the scanner communicates with safety devices via cyclic messages only. You configure input and output connections in the DeviceNet safety scanner to transfer input and output data to and from DeviceNet safety I/O modules and the GuardPLC controller.

The scanner can make data available to other DeviceNet scanners using Target connections. When Target connections are enabled, the safety scanner looks like a standard I/O device that can be added to another scanner’s scanlist,or a safety target device allowing another safety scanner to connect to the safety data by adding a safety connection. This allows for the transfer of data signals between two GuardPLC controllers for safety interlocking and distributed safety control. Standard data signals can also be exchanged with PLCs, HMIs, or a ControlLogix system with a 1756-DNB scanner on the DeviceNet network. For more information on Target connections, see Appendix B.

Understand Data Signals

In order to understand how to use data signals from the safety scanner in your GuardPLC application logic, you must know:

• whether the signal data is regarded as safety or standard data in the end device, and

• whether the signal data was transferred over a safety connection or a standard connection.

The following table defines permitted uses of safety and standard signals based on connection and signal type.

End Device Signal Definition

Safety Safety Safety

Standard Safety Standard

Connection Type Permitted Use in Application

Standard Standard

IMPORTANT

Only safety signal data transmitted over safety connections may be used as safety data in safety application logic.

Publication 1753-UM002A-EN-P - July 2005

1-4 Before You Begin

How Data Tables Work

To exchange data, the GuardPLC controller and the 1753-DNSI use two pairs of data tables: one pair for safety input and output data and one pair for standard input and output data.

Connection Type Scanner Inputs Scanner Outputs

Scanner is the originator.

Data the scanner reads from its target nodes. The data layout is defined by the target node’s configuration.

Data the scanner writes to its target nodes. The data layout is defined by the target node’s configuration.

Safety

Standard

Scanner is the target.

Scanner is the master.

Scanner is the slave.

Data that one other CIP Safety originator may write on the scanner’s target output connection point. The data signals to be written are selected in RSLogix Guard PLUS!.

Data the scanner reads from its standard DeviceNet slaves. The data layout is defined by the target node’s configuration.

Data that one other standard DeviceNet master can write on the scanner’s slave mode outputs. The data signals are selected in RSLogix Guard PLUS!.

Data that one or more other CIP Safety originators may read from the scanner’s target input connection point. The data signals to be read are selected in RSLogix Guard PLUS!.

Data the scanner writes to its standard DeviceNet slaves. The data layout is defined by the target node’s configuration.

Data that one or more other standard DeviceNet master can read from the scanner’s slave mode inputs. The data signals are selected in RSLogix Guard PLUS!.

Standard DeviceNet Explicit Messaging connections are limited to read-only access to safety data.

ATTENTION

To maintain the safety integrity level (SIL) of your system, you must ensure that safety data read by Explicit Messaging is used only as standard data in your application.

Publication 1753-UM002A-EN-P - July 2005

How to Distinguish Between Standard Data and Safety Data in RSLogix Guard PLUS!

In the HSP Signal Connection dialogs (in RSLogix Guard PLUS!), signals that are transferred over safety connections are shown in white text on a red background. Signals transferred over a standard connection are shown in blue text on a gray background.

Before You Begin 1-5

Since this colorization only applies to the Connect Signals dialogs available from the HSP protocol context menu, we strongly recommend that when using both standard and safety signals in your application, you use a naming convention to visually distinguish between standard and safety signals throughout the RSLogix Guard PLUS! programming environment. For example, use a prefix of ‘std_’ for any signals that are standard and a prefix of ‘safe_’ for any signals that are safety-related.

Role of RSNetWorx for DeviceNet and RSLogix Guard PLUS!

IMPORTANT

The red/blue colorization is not a guarantee that a signal is a safety signal. It only indicates which type of connection the signal was transferred over. The classification of the end node must also be considered. Any signal that appears in the (blue) standard Connect Signals window and is regarded as safety at the end device must be treated as standard in your application. Any signal that appears in the (red) safety Connect Signals window and is regarded as standard at the end device must be treated as standard in your application. In order for a signal to be regarded as a safety value in your application, the end device configuration must treat it as safety and it must be transferred over a DeviceNet Safety connection.

RSNetWorx for DeviceNet, version 6.x or higher, is the configuration tool for the 1753-DNSI on the DeviceNet Safety network. RSNetWorx for DeviceNet can connect to the safety scanner directly over the DeviceNet network via an RS-232 interface (1770-KFD module) or PC card (1784-PCD or -PCID) or through another network using a bridge device. A bridge can be either a single device with communication ports for two different networks, or separate communication devices in the same chassis.

DeviceNet Safety Port

Before You Begin 1-7

The 1753-DNSI features two communication ports; one for DeviceNet communications and one for High-Speed Safety Protocol (HSP) communication with a GuardPLC controller. The HSP port is a 1 Mbps, full-duplex RS-485 interface.

The safety scanner also features a 4-character dot-matrix display, which provides status and error codes. Status LEDs on the safety scanner indicate module, network, and HSP connection status. See Chapter 10 for more information.

Supported Connections

The DeviceNet Safety port supports a maximum of 32 DeviceNet Safety input connections, 32 DeviceNet Safety output connections, and standard connections for up to 63 nodes.

The safety scanner does not support Quick Connect, Auto Device Replacement or Autoscan.

Safety Connections

The safety scanner supports single-cast producing or consuming connections and multi-cast consuming connections as a DeviceNet Safety originator. Up to 32 producing and 32 consuming safety connections can be made. These connections are used when the safety scanner is communicating to distributed safety I/O modules.

The safety scanner also supports the use of two safety targets, defined by RSLogix Guard PLUS! and made available via the Target Connections File. One target may be a single- or multi-cast producer, the other may be a single-cast consumer. These connections allow the safety scanner to look like safety I/O to another safety scanner on the network, and can be used for interlocking of safety data between two GuardPLC systems.

Standard Connections

The safety scanner supports the following standard DeviceNet connection types:

Communication Rate

The safety scanner supports the following communication rates, but does not support autobaud:

• 125 Kbps (default)

• 250 Kbps

• 500 Kbps

Physical Layout of the DeviceNet Safety System

Planning your system helps ensure that you can:

• meet safety times

• use memory and bandwidth efficiently

• fulfill device-specific requirements

• leave room for system expansion

Before configuring your 1753-DNSI scanner, you should be familiar with each of the DeviceNet devices on your network. You should know each device’s:

• system safety time requirements

• communication requirements

• I/O size

• frequency of message delivery

You must also understand and define which data elements can be treated as safety and which as standard in your intended configuration.

Publication 1753-UM002A-EN-P - July 2005

DeviceNet Safety I/O Performance Factors

Safety nodes have priority on a DeviceNet network, but the performance of DeviceNet Safety I/O modules can be affected by the:

• baud rate of the network (Lower baud rates mean slower transmissions and slower responses.)

• packet size for the various connections (Bigger packets may result in fragmented messages and slower responses than single-packet messages, but use fewer resources.)

• type and number of connections used (Using point-to-point connections to make multiple connections to an input node uses more resources than a multicast connection.)

• RPI of the devices (Lower RPIs consume more bandwidth but lower system reaction time.)

Before You Begin 1-9

Choose a Communication Rate for the Network

The default communication rate for a DeviceNet network is 125K bit/s. This is the easiest communication rate to use.

If you choose to use a different communication rate, the length of the trunkline and type of cable determine which communication rates your application can support.

Communication Rate

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

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

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

IMPORTANT

network, make sure that all devices change to the new communication rate. Mixed communication rates produce communication errors.

Set the baud rate of the DeviceNet Safety Scanner using the Node Commissioning tool in RSNetWorx for DeviceNet. See Commission All Nodes on page 3-2.

The following table lists the most common methods for setting communication rates for other DeviceNet devices.

Method Description

autobaud At power up, the device automatically sets its communication

rate to the baud rate of the first device it finds on the network. The device remains set until it powers up again.

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

switches or pushbuttons on the device

software Some devices require a programming device to set its address

Some devices have switches or a pushbutton that sets the communication rate. Typically, the switch or pushbutton lets you select either autobaud or a fixed communication rate (125K, 250K, or 500K bit/s). The device reads the switch setting at power up. If you change the setting, you must cycle power for the change to take effect.

and communication rate. For example, you can use the Node Commissioning tool in RSNetWorx for DeviceNet to set the communication rate of a device.

Publication 1753-UM002A-EN-P - July 2005

1-10 Before You Begin

Assign an Address to Each Device

To communicate on the DeviceNet network, each device requires its own address. Follow the recommendations below when assigning addresses to the devices on your network.

Give this device This address Notes

DeviceNet network, use address 62 for the computer or bridging/linking device.

non-commissioned node typically enters the network.

Standard DeviceNet assigns communication priority based on the device’s node number. The lower the node number, the higher the device’s communications priority. This priority becomes important when multiple nodes are trying to communicate on the network at the same time.

DeviceNet Safety nodes have additional priority on the network, regardless of node number. DeviceNet Safety communications from devices with lower node numbers have priority over DeviceNet Safety communications from devices with higher node numbers.

Manage the Safety Network Number

Safety Network Numbers assigned to each safety network or network sub-net must be unique. You must ensure that a unique Safety Network Number (SNN) is assigned to each DeviceNet network that contains safety nodes.

Each DeviceNet Safety device must be configured with an SNN. The combination of SNN and DeviceNet node address provides a unique identifier for every safety node in a complex industrial network. This unique identifier prevents data intended for a specific target node address on one DeviceNet subnet from being mis-routed to a node with the same node address on a different DeviceNet subnet.

SNN Formats

The Safety Network Number (SNN) can be either software-assigned (time-based) or user-assigned (manual). These two formats of the SNN are described in the following sections.

Time-based SNN (Recommended)

In the time-based format, the SNN represents the date and time at which the number was generated, according to the personal computer running RSNetWorx for DeviceNet.

1 Publication 1753-UM002A-EN-P - July 2005

4-2 Manage the Safety Network Number

Manual SNN

In the manual format, the SNN represents entered values from 1 to 9999 decimal.

Assignment of the SNN

TIP

SNNs can be generated automatically via RSNetWorx for DeviceNet or manually assigned by the user. Automatically generated SNNs are sufficient and recommended for most applications.

You can use the Copy button on the Set Safety Network Number dialog to copy the SNN to the

Windows

clipboard.

Automatic (Time-based)

When a new safety device is added to the network configuration, a default SNN is automatically assigned via the configuration software, as follows:

• If at least one safety device already exists in the DeviceNet network configuration, subsequent safety additions to that network configuration are assigned the same SNN as the lowest addressed safety device.

• If no other safety devices exist in the DeviceNet network configuration, a time-based SNN is automatically generated by RSNetWorx for DeviceNet.

Publication 1753-UM002A-EN-P - July 2005

Manage the Safety Network Number 4-3

Manual

The manual option is intended for systems where the number of DeviceNet subnets and interconnecting networks is small, and where you might like to manage and assign SNNs in a logical manner pertaining to their specific application.

IMPORTANT

To set the SNN in a safety device via RSNetWorx for DeviceNet, select the device in the hardware graphic view and choose Set Safety Network Number from the Device menu.

IMPORTANT

If you assign SNNs manually, take care to ensure that system expansion does not result in duplication of SNN and Node Address combinations.

When you set the SNN, the device is returned to its factory default configuration.

Set the SNN in All Safety Nodes

A time-based SNN is automatically generated when the first new safety device is added to the network. Subsequent additions to the network are assigned the same SNN as the lowest-addressed safety device. This automatic, time-based SNN is sufficient and recommended for most applications.

Publication 1753-UM002A-EN-P - July 2005

4-4 Manage the Safety Network Number

If you need to set the SNN for a particular device, follow the steps below:

1. Click on the target device in the hardware graphic view and select Set Safety Network Number from the Device menu.

2. Select Time-based and click the Generate button, or select Manual and fill in a Decimal number from 1 to 9999. Click OK.

Publication 1753-UM002A-EN-P - July 2005

TIP

You can use the copy and paste buttons on the Set Safety Network Number dialog to copy and paste SNNs between devices and to make a record of the SNN.

3. Verify that the Network Status LED is rapidly alternating between red and green on the correct device and click OK.

Manage the Safety Network Number 4-5

SNN Mismatch

RSNetWorx for DeviceNet compares the offline SNN to the online SNN during each browse operation, one-shot or continuous, and during upload and download operations. If the SNNs do not match, RSNetWorx for DeviceNet indicates an error with the SNN. The hardware graphic view displays the ! symbol over the safety device icon. You can resolve the SNN error from the Safety Network Number Mismatch dialog, as described on page 4-5.

When online, RSNetWorx for DeviceNet also checks for an SNN mismatch whenever a safety device’s Device Properties dialog is selected, either from the Device > Properties menu or by double-clicking on the device.

5-4 Configure DeviceNet Nodes and Connections

The Add Safety Connection dialog allows you to configure a connection.

1. Select the desired connection by choosing the Connection Name.

2. Select a type of connection, either Multicast (input connections only) or Point-to-point (input or output connections).

3. Select ‘Configuration signature must match’. This selection directs the scanner to ensure that the target safety device contains the correct configuration before opening the safety connection.

IMPORTANT

If you do not choose ‘Configuration signature must match’, you are responsible for ensuring the safety integrity of your system by some other means.

4. Review the Connection Reaction Time Limit.

The Connection Reaction Time Limit is the maximum age of safety packets on the associated connection. If the age of the data used by the consuming device exceeds the Connection Reaction Time Limit, a connection fault occurs. Adjust the Connection Reaction Time Limit by changing the RPI or the Advanced Communication Properties as described in steps 5 and

Publication 1753-UM002A-EN-P - July 2005

5. Set the Requested Packet Interval (RPI).

The RPI specifies the period at which data updates over a connection. The RPI is entered in 1 millisecond increments, and the scanner supports a valid range of 5 to 500 ms with a default

Configure DeviceNet Nodes and Connections 5-5

of 10 ms. Other target devices may have more limited RPI constraints. Consult the documentation for each type of target device to determine its supported range and incremental values.

Modifying the RPI affects the Connection Reaction Time Limit. For simple timing constraints, setting the RPI is usually sufficient. However, for more complex requirements, use the Advanced… button to further adjust the timing values affecting the Connection Reaction Time Limit as described below.

6. Set the Advanced Safety Connection Properties (if required).

• Timeout Multiplier – The Timeout Multiplier determines the number of RPIs to wait for a packet before declaring a connection timeout. This translates into the number of messages that may be lost before a connection error is declared.

For example, a Timeout Multiplier of 1 indicates that messages must be received during every RPI interval. A Timeout Multiplier of 2 indicates that 1 message may be lost as long as at least 1 message is received in 2 times the RPI (2 x RPI).

• Network Delay Multiplier – The Network Delay Multiplier defines the message transport time that is enforced by the communications protocol. The Network Delay Multiplier specifies the round trip delay from the producer to the consumer and back to the producer. You can use the Network Delay Multiplier to reduce or increase the Connection Reaction Time Limit in cases where the enforced message transport time is significantly less or more than the RPI.

Navigate through the available tabs to review and modify the module’s configuration. Refer to the user manual for the module for additional information on how to set up the module’s configuration.

To configure the safety scanner for standard communications, you set up a scanlist and define the memory locations for the standard data of each device.

Standard Communication Properties

Configure the standard communication properties of the safety scanner on the Module tab of the Scanner Properties page. You can use the Module Defaults button to return the safety scanner to the default settings, which are shown below.

Publication 1753-UM002A-EN-P - July 2005

Interscan Delay

This parameter defines the delay time the scanner uses between scans of the DeviceNet network. If you have slave devices configured for Polled behavior in the scanner’s scanlist, Interscan Delay (ISD) defines the amount of time the scanner waits between writing outputs to the polled devices.

Configure DeviceNet Nodes and Connections 5-7

Increasing the ISD time causes a longer network scan, which adversely affects overall input-to-output performance. However, the increase allows lower priority messages to get more network access. These lower priority messages include those used to do network browsing and configuration upload and download functions. So, if these network functions are sluggish on your system, increasing the ISD time is one way to make more bandwidth available for lower priority messages.

In addition, if the last node in your scan list produces a large amount of polled data, you may want to increase the ISD time to ensure that the entire response is received before the next poll request is sent to that node.

Foreground to Background Poll Ratio

Devices set for polled behavior can be polled on every I/O scan (foreground) or they can be polled less frequently (background). Setting a device for foreground or background behavior is done when you configure each device on the Scanlist tab, from the Edit I/O Parameters dialog. A ratio of 2 means that any nodes included on the background list are polled every other scan cycle. A ratio of 3 means they are polled on every third cycle, etc.

Advanced Module Settings

Clicking on the Advanced… button lets you to set the Expected Packet Rate (EPR) and the Transmit Retries as described below.

• Expected Packet Rate (EPR) – When the scanner opens a polled or strobed I/O connection, it uses this value as a maximum timeout (Expected Packet Rate) with the device. If the device does not receive a packet from the scanner within 4 times the EPR value, the slave device drops the connection. If the scanner does not receive a packet from the slave within 4 times the EPR value, it drops the connection and periodically attempts to reopen the connection.

Publication 1753-UM002A-EN-P - July 2005

5-8 Configure DeviceNet Nodes and Connections

When a standard connection is dropped, status bits in the scanner identify that the slave is not online. Slave behavior when a connection is dropped is a function of the slave device. If the slave is an I/O device, the standard outputs will be cleared, held at last state, or set to a fault condition (refer to the slave device’s documentation for actual I/O behavior when a connection is dropped).

When an input connection is dropped, the scanner sets the corresponding data in the data tables sent to the GuardPLC controller via the HSP connection to the safety state (0).

The EPR default value is 75 milliseconds.

IMPORTANT

Changing the EPR number should be done carefully because it effects how long it takes the scanner to detect a missing device.

• Transmit Retries – Transmit Retries specifies the number of times the scanner attempts to retransmit a change of state or cyclic message that has not been acknowledged by the slave device before dropping the connection.

Create a Scanlist

The scanlist defines the standard devices (nodes) with which the scanner is configured to exchange I/O data.

Publication 1753-UM002A-EN-P - July 2005

Configure DeviceNet Nodes and Connections 5-9

Available Devices

These are the devices on the network that have the ability to be standard slave I/O devices. The DeviceNet Safety Scanner, as well as any other scanners that have been configured to support a standard slave-mode interface will also appear in this list. Slave-capable devices do not have to be used as slave I/O by a scanner. They may alternately be used as slave I/O by another scanner on the same network, or they may have dual functionality.

Scanlist

These devices have been assigned to be slave I/O to this scanner. The outputs of a slave device on DeviceNet can only be owned by one master at a time. Data mappings for each device in the scanlist are configured using the input and output tabs. Add an available device by selecting the device and clicking on the add arrow >. The double-arrow >> adds all the available devices to the scanlist.

It is not necessary to enter safety nodes into the safety scanner’s scan list. All safety connections are configured on the Safety Connections tab. You only need to put a safety device into the safety scanner’s scanlist if you are communicating with that device via a standard connection and exchanging standard data with it.

Automap on Add

Automap allows a slave’s I/O to be automatically mapped into the scanner’s input or output image tables when the slave device is added to the scanlist. DO NOT check this box if you intend to map a slave device into a particular input or output memory location.

Edit I/O Parameters

These parameters will vary depending upon the slave device. Information on configurable parameters is usually provided in the device’s documentation.

Electronic Key

The electronic key is used to ensure that a particular slave device always matches the intended device when the scanner initiates a connection to it. When one of the devices in the Scanlist section is highlighted, these boxes may be checked to indicate to what extent the key parameters must match the actual device on the network. A match of just Device Type can be selected or the additional parameters of Vendor ID and Product Code may be incrementally added.

Publication 1753-UM002A-EN-P - July 2005

5-10 Configure DeviceNet Nodes and Connections

Should the scanner detect a mismatch with any of the key parameters checked, an Electronic Key failure (status code 73) will occur for that slave device and the scanner will abort the connection establishment process.

Configure Standard Inputs

The Input tab lets you define how standard data from all of the scanner’s slave devices are mapped into the input image of the controller.

Configure GuardPLC Controller Settings

Use the GuardPLC tab to configure the scanner’s HSP connection parameters.

Controller ID

The Controller ID (SRS) uniquely identifies a particular GuardPLC controller within a network of controllers. Its use ensures that this configuration is applied to the correct controller. Specify the Controller ID of your selected GuardPLC controller, or this will automatically be provided when you associate the scanner and controller as described in Chapter 7.

Scanner ID

The scanner ID is a read-only value which uniquely identifies the scanner and is required to connect the GuardPLC controller to the scanner. The scanner ID is automatically generated by RSNetWorx for DeviceNet using the SNN and DeviceNet address of the scanner. It is exported in the Scanner Signals file and is viewable in the associated RSLogix Guard PLUS! project.

HSP Signature

The HSP Signature is a read-only value that is unique to each layout of the signals within the data exchanged between the GuardPLC controller and the 1753-DNSI. The HSP Signature is calculated based on the scanner’s configured safety and standard connections and any target connections defined in RSLogix Guard PLUS!. It is passed to RSLogix Guard PLUS! via the Scanner Signals File. The HSP signature changes only when a modification occurs in the layout of the signals exchanged between the controller and scanner.

Configure DeviceNet Nodes and Connections 5-13

Scanner Receive Timeout

The Scanner Receive Timeout is the amount of time (in milliseconds) that the scanner waits for a request from the GuardPLC controller before timing out the HSP connection. If the scanner does not receive a message from the GuardPLC controller within this time, all output connections are transitioned to the idle state, causing the safety outputs to transition to the safety state and standard outputs to follow the behavior dictated by their configuration.

Set the Scanner Receive Timeout equal to the Watchdog Timeout specified on the Properties dialog of the controller resource in RSLogix Guard PLUS! Hardware Management. Refer to the GuardPLC Controller Systems User Manual, publication number 1753-UM001, for information on setting the Watchdog Time.

Max. Scanner Response Time

The Max Scanner Response Time is the maximum amount of time (in milliseconds) allotted for the scanner to process an HSP request from the controller, and then format and send a proper response. If the scanner cannot respond within this time frame, then all output connections transition to the idle state, causing the safety outputs to transition to the safety state and standard outputs to follow the behavior dictated by their configuration.

The Max Scanner Response Time should be set to a value that includes the maximum observed statistical scanner response time over several hours of operation, plus a Margin of Safety equal to 3 ms or 10% of the maximum observed scanner response time. When online, you can view the Minimum, Maximum, and Average Observed Scanner Response Times by selecting the Statistics… button.

2. Configure HSP communications. Right-click on HSP Protocol and select Properties.

The Controller Receive Timeout is the amount of time that the controller waits to receive an HSP response from the scanner before closing the HSP connection.

Controller Resend Timeout is the amount of time that the controller waits for the acknowledgement of a message before it resends it.

Publication 1753-UM002A-EN-P - July 2005

6-4 Create a GuardPLC Project with High-Speed Safety Protocol

Use the following guidelines when setting the Controller Receive Timeout and Controller Resend Timeout:

• In environments where no HSP retries are required, set the Controller Receive Timeout to the amount of time required for the controller to send the HSP request, for the scanner to process the request, and for the scanner to send a response back to the controller. This value can be determined by observing the Response Time values displayed on the HSP protocol tab of the Resource Control Panel.

Set the Controller Receive Timeout to be greater than or equal to the maximum value reported plus a margin of safety (3 ms or 10% of the maximum value reported). The Controller Resend Timeout should be set to zero.

• In electrically noisy environments, configuring retries on the HSP link may be required. Set the Controller Resend Timeout to be equal to or greater than the Max Response Time value reported on the HSP Protocol tab of the Resource Control Panel plus a margin of safety (3 ms or 10% of the maximum value reported). To enable a single retry, the Controller Receive Timeout must be 2 times the Controller Resend Timeout. To enable 2 retries, the Conroller Receive Timeout must be 3 times the Controller Resend Timeout.

• The controller’s Communications Time Slice, found on the Properties dialog of the controller Resource, must be greater than the Controller Receive Timeout to enable proper HSP operation. If other protocols are in use on the controller Resource, then the Communications Time Slice should be increased to accommodate their use in conjunction with HSP. The Maximum Communication Time Slice setting on the Device Properties page should be set to the Maximum Communication Time Slice observed on the Control Panel’s Statistics tab plus a margin of safety (6 ms or 10% of the maximum value reported).

Individual DeviceNet safety or standard connection errors do not cause the HSP connection to close. In the case of a faulted DeviceNet connection, any input data associated with that connection is forced to zero before being transmitted to the GuardPLC controller over HSP.

Your GuardPLC application logic can control the operation of the HSP connection, by writing a value to the signal associated with the HSP Connection Control Word.

To connect a signal to the HSP Connection Control Word, right-click on your HSP protocol in the RSLogix Guard PLUS! Hardware Management window and choose Connect Signals>HSP Data.

The following table describes the possible mode settings for the HSP connection.

Verify Your DeviceNet Safety Configuration

IMPORTANT

The Safety Device Verification Wizard, accessed from RSNetWorx for DeviceNet, guides you through the process of verifying the configuration of your safety devices and provides the means for Safety-Locking those devices. The verification process includes upload and comparison of the configuration stored in the device and the configuration stored in the RSNetWorx for DeviceNet configuration file. The configuration is displayed in a report to facilitate visual verification and record keeping.

IMPORTANT

Before running the Safety Device Verification Wizard, you should browse and upload your network and test the safety devices on your network to ensure that they are operating properly. You must fully test your application prior to safety-locking your devices.

Refer to the GuardPLC Controller Systems Safety Reference Manual, publication number 1753-RM002 for information on verification testing for safety applications.

Some devices may not support verification by the Safety Device Verification Wizard. Consult the user documentation to determine the method required for verifying these devices.

Connection Status

You can monitor the HSP and DeviceNet Safety and standard connection status using the scanner’s connection status bits and the related GuardPLC application signals as discussed in the following sections.

DeviceNet Connection Status Bit Behavior

The following table describes the combined operation of the DeviceNet connection status bits.

Connection Fault

0 = Valid 0 = Run Data is actively being controlled by the producing device. The producing device is in the Run mode.

0 = Valid 1 = Idle The connection is active and the producing device is

Not applicable. The connection is faulted. The state of the

IMPORTANT

producing device is unknown. The data sent to the controller for this connection is reset to 0. At start up, the standard fault bit defaults to 0. If the first attempt to connect to the slave device is not successful, then the connection will be reported as faulted. When one or more of the standard connections to the slave node timeout, the corresponding fault bit is set. When all of the connections to a slave node are in the established state, the fault bit is set to 0.

The fault bit for the slave-mode interface is not used; it is always 0.

The bits in the table above are only accurate if the HSP connection is established.

As with any communications channel, you must use the connection status bits in your application program logic to achieve a SIL 3 system.

Standard DeviceNet Connection Status

The Faulted Node Table and Idle Node Table attributes of the Scanner Configuration Object (class 0x90) contain standard DeviceNet connection status information as described in the following table.

Name Attribute Data Type Access

Faulted Node Table

0x10 a Array of

BOOL

Get 0 = The device is not faulted or is

Attribute Value Description

not configured. 1 = The device is faulted.

Idle Node Table

0x11 b Array of

BOOL

Get 0 = The device is not in Idle mode

or the device is not configured. 1 = The Device is in Idle mode.

(1) The bit offset in the table corresponds to the node number. For example, bit 0 corresponds to node 0…bit 15

corresponds to node 15.

For nodes with more than one connection type enabled (that is, connections with both an input and output connection configured), the status bit reflects the logical ‘OR’ of the status for each configured connection.

(1)

User application program logic only needs to consider status bits associated with nodes that have one or more connections. The status bits of nodes without any connections may be ignored. The list of configured connections can be obtained from the RSNetWorx for DeviceNet report feature by selecting File>Generate Report.
