PanelView Message Types All PanelBuilder screen control or display objects are assigned a tag

when an application is developed. The tag defines an address, data type, initia l value, and other parameters fo r the data assigned to the object. The Tag Editor has 3 dialogs for DeviceNet objects, depending on the message type selected:
•I/O Slave
Explicit Server
Explicit Client. All three message types can exist and run simultaneously within a
single PanelBuilder appl ic ation.
Publication 2711-6.0.4
11

I/O Slave Messaging The I/O slave message connections use the pre-defined Master/Slave connection

set. Exchanged data is grouped in Assembly Instances created using the PanelBuilder Tag Editor. The first input instance and the first output instance are exchanged using DeviceNet I/O slave messages. The PanelView supports a maximum of 64 input and 64 output words. The number of words exchanged is determined by the Communication Setup dialog in PanelBuilder and the Master (scanner) device DeviceNet configuration.
Data at the PanelView tag addresses can be mapped to any location in the DeviceNet scanner b ut mu st be a conti nuo us bloc k of 1- 64 inp ut o r outp ut words. Change-of-State, Cyclic and Polled I/O modes are supported. Strobed I/O messaging is not supported by the PanelView.
DeviceNet PanelView terminals support the following types of I/O messaging when configured in the D eviceNet scanner.
Polling
The DeviceNet scanner initiates communicati ons with the PanelView terminal by sending a Polled Request. The Pane lV iew r esponds to the request by providing the requested data. Data is sent by the PanelView at intervals determine d by the ladder logic pr ogram and/ or the I nters can Delay of the scanner ( not the PanelView Interscan De lay setting).
Change of State (COS)
The DeviceNet scanner establishes the connection with the PanelView terminal. The exchange of data is Asynchrono us. Outpu t data i s sent to the Panel V ie w from the scanner only when th e data chan ges. The P anelView terminal sends Input data back to the scanner only wh en the data changes. Acknowledged/ Unacknowledg ed
modes are available (see ‘Notes’ on the next page).
Cyclic
Data is exchanged between the PanelView terminal and scanner at the Heartbeat Rate. The Heartbeat Rate is set using a DeviceNet Manager tool, such as RSNetwork for DeviceNet, during network setup.

I/O Slave Messaging Notes and Recommendations
The I/O size specified in the PanelView terminal (“Configuring DeviceNet Communications” on page 8) must match the I/O size expected b y the DeviceNet scanner.
COS, Polled and Cyclic are selected during configuration of the scanner. You do not have to configure the PanelView to accept COS, polled and cyclic messages.
Both acknowledged and unacknowledged Change-of-State / Cyclic modes are allowed. We recommend that you use the acknowledged COS mode since the device sending the message never knows that data was received when unacknowledged COS is used.
Publication 2711-6.0.4
If acknowledged mode is used, no data is returned in the acknowledgment.
The Polled + COS option is allowed but the polled response data and the COS data are from the same assembly. For the most efficient operation, do not use the Polled + COS option.
Use of COS or Cyclic I/O connections is highly recommended over Polled I/O for I/O sizes in excess of 32 words (to minimize network traffic).
I/O messages have higher priority than Explicit messaging.
13

Explicit Messaging The PanelView with DeviceNet can communicate with other DeviceNet products

that have Unconnected Message Manager (UCMM) capability. The PanelView can function as either a:
Client - where the PanelView initiates the exchange of data with a server.
Server - where the PanelView responds to data request from a client. UCMM data transfers are referred to as either Explicit Client or Explicit Server
and are configured in the PanelView tag form dialog. For more information on specific DeviceNet commands and functions, contact the Open DeviceNet Vendors Association (ODVA).
Explicit Server
With Explicit Server messaging, the PanelView terminal (Server) controls the data and waits for client device(s) to request or send data. Assembly Instances 3-16 contain the PanelView data with up to 64 words in each instance (total of 896 words can be transferred). Inputs and outputs cannot be placed in the same instance.
Only Get_Attribute_Single and Set_Attr ibute_Single commands are support ed. For PanelView objects wi th Explicit Server addressing :
Get_Attribute_Single (service code 0xOE)
External client devi ce reads the PanelView objects (tags).
Set_Attribute_Single (service code 0x10)
External client devi ce sends values to the PanelView output objects (tags).
The following illustrates explicit server messaging functions:
For Inputs: Client device initiates communications
with Explicit ‘GET’ Message to obtain input data from the PanelView (server). The PanelView (server) responds by sending data.
For Outputs:
Client device sends data using an Explicit ‘SET’ Message to set output data. The PanelView (server) responds that data has been received.

Notes on using Explicit Server Messages
Explicit Server messages have a lower priority than I/O slave messages.
Client devices access input/output data from the value attribute (attribute 3) of the assembly object class (class code 4) using the specified tag instance number (instance 3-16).
The PanelView has only one general purpose Explicit message connection available at a time to an external client device. Remember this when creating applications that require multiple Explicit message server connections.
Data from one client device can overwrite the data sent by another client.
Publication 2711-6.0.4
15
Explicit Client
The PanelView can also communicate using peer-to-peer Explicit-Client messaging, where the PanelView (Client) initiates the connections and obtains data from other devices (Server). Connections to other devices are created with Tag Form addresses and use explicit messages to read and write values to other DeviceNet nodes. PanelView Explicit-Client comm unications only support transactions with UCMM capable network devices.
Only Get_Attribute_Single and Set _Attribute_Single commands are sup ported. For PanelView objects wi th explicit client addressing:
Get_Attribute_Single (server code 0xOE) The PanelView sequentially scans values addressed to PanelView objects in the current screen (or global objects) and reads data from the external server device.
Set_Attribute_Single (server code 0x10) The PanelView sends values to the external device when a change of state is detected on that input.
Output data is acquire d similar to polling an d input dat a is sent on Cha nge of Stat e (COS). The location of the data in the DeviceNet Server device must be specified in the PanelView data tags. Data locations on the server device are specified by providing the Node Address, Class, Instance, Attribute and the Byte/Bit Offset. The Class, Instance and Attribute are provided in the user documentation of the device the PanelView is communicating with. Refer to Appendix A for the Packet Bytes and Offsets required for read and write tags.
The following illustrates how Explicit-Client messaging functions:
Explicit-Client Message Tags
For Read tags:
PanelView (client) device initiates communications with Explicit
‘GET’ Message to obtain input data from the server device. The server device responds by sending data.
For Write tags:
PanelView (client) device sends data using an Explicit ‘SET’ Message to set output data. The server device responds that data has been received.

!
Devices must have a sufficient number of available connections to support an Explicit Messag e conn ection by the PanelView and any other connections required by the application. This includes a Group 2 Only Slave owned by a Group 2 Only Client such as a scanner that can proxy the UCMM service for the slave.
Data read/written must be accessible as an externally addressed DeviceNet attribute with the Get_Attribute_Single and Set_Attribute_Single commands.
Explicit-Client messaging is not designed for high speed communications and uses lower priority messaging on DeviceNet. Use I/O messaging for time critical applications.
PanelBuilder Version 2.40 and later allows you to use an offset for writing multiple words in each instance. The PanelView reads or writes an entire Assembly Instance. The Packet Bytes and Bit Offset in the tag address filter the requested information.

Configure the 1203-Communications Module to operate with the PanelView terminal using Explicit-Client messaging. See Publication 1203-5.3 for details on ho w to confi gure t he commun icati ons mo dule.
Switch 1-7 must be in the ON position
(Disable Fault on Comm Loss)
This setting instruct s t he communication module to ignore the loss of the virtual connection to the PanelView terminal. This is important since the DeviceNet PanelView terminal in the Explicit-Client mode repeatedly opens and closes the communication link used to access data. If switch 1-7 is left OFF the driver will stop whenever the PanelView closes a connection to the communications module.
ATTENTION: When the 1203-GK5 module is set with switch 1-7 in the ON position, all DeviceNet devices
!
(including PanelView) with Explicit connections to the drive can leave the network with out any indicatio n provided to the drive.
A TTENTION: Any operation using Explicit messaging
to control the operation of machinery must not be involved with system safety or of a critical nature that could potentially cause personal injury or equipment damage. Safety circuits must be hard-wired and not controlled by the PanelView terminal. Operations that are critical to safety must be under the control of a supervisory controller or computer programmed with the appropriate safety logic or programming.
Download and Run the Application
Validate and download the application to the PanelView terminal. The Accel 1 variable of the 1305 drive can be read or written using the control screen (screen 1). The status of the drive is displayed on the status screen (screen 2).

Glossary

Assembly Object
DeviceNet products usually have one or more Assembly Objects. The purpose of the Assembly Object is to group diff erent Attributes (data) so they can be moved by a single message. See also: Instance
Attribute
A data element that can be read or written. Each attribute is assigned an integer value (Attribute ID) as an identifier in the range of 0-255.
CAN
Acronym for Controller Area Network. DeviceNet is based on CAN.
CAN ID
or identifier is an 11-bit field that identifies each message on any CAN network. CAN IDs must be u nique.
Class
A set of objects that behave in a similar manner. Each object class is assigned an integer value called the Class ID (0-65535). Classes 0-99 are open, classes 100-199 are vendor specific. Higher numbers are divided between open, reserved and vendor specific, but are currently rarely used. Vendor specific classes are defined by the vendor.
Client
The device that originates a transmission. Applies to Exp licit Messaging. With Explicit Client messaging, the PanelView terminal is the client device that requests or sends information from/to a server device. See Server.
Connection
The logical link between a node and one or more other nodes (for prod uction or consumption). Most nodes have at least two conne ctions (one explicit, one I/O).
COS
Acronym for Change of State. I/O messages are sent when data changes. If no change of state occurs, messages are sent at a pre-determined (heartbeat) interval.
Cyclic
I/O messages that are sent at a predefined fixed rate.
DeviceNet
DeviceNet is an open network standard based on CAN (Controller Area network). The specification and p rotoc ol ar e o pen. Vendors are not req uired to purchase hardware, software or licensing rights to connect devices to a system. Anyone may obtain the DeviceNet Specification from the Open DeviceNet Vendor Association, Inc. (ODVA) for a nominal reproduction charge (http://www.odva.org).
Publication 2711-6.0.4
Glossary-2
DeviceNet Manager
Personal computer running DeviceNet Manager software (Catalog No. 1787-MGR). This software configures DeviceNet nodes using explicit messages. Also see RSNetworx.
EDS
Acronym for the Electronic Data Sheet. A specially formatted ASCII file
that provides information about a device’s configuration data context, content, and format. The information in an EDS allows configuration tools to provide information screens that guide a user through the steps necessary to configure a device.
Explicit (Client or Server) Messages
Provide multi-purpose, poi nt-t o- poi n t commu nicat i on paths between 2 devices. They provide the typical request/response-oriented network communications to perform node configuration and problem diagnosis. Explicit messages typically use low priority identifiers an d contain the specific meaning of the message right in the data field. This includes the service to be performed and the specific object attribute address . They do not need to be active all the time.
Identifier
See CAN ID
Instance
An actual object such as a counter. The terms Object Instance, Object, and Instance all refer to an actual object and are of ten interchangeable. See also: Assembly Object and Object
I/O Slave Messages
I/O messages are time critical, control oriented data. They provide a dedicated, special purpose communication path between a producing application and one or more consuming applications. They are exchanged across single or multi-cast connections and typically use high priority identifiers. Unlike explicit messages, I/O messages contain only data, they do not contain any prot ocol in the 8-byte field.
Node Address
A unique number that identifies a device on a DeviceNet network.
Object
Each object has a defined behavior and data structure. Different objects respond differently to the same event. See Instance.
Poll
Messaging that involves an output message from the master to the slave. The slave responds with an input message. These messages can be of any reasonable length, including zero.
Predefined Master/Slave Connection Set
A simplified network scheme in which controllers (PLCs /SLCs) and computers are usually masters and the PanelView terminal is the slave. It is possible for a node to simultaneously b e both master and slave ( for examp le, the DeviceNet Scanner 17xx-SDN). The Predefined Master/Slave Connection Set includes three types of I/O connections: Poll, Strobe and COS/Cyclic.
Publication 2711-6.0.4
Glossary-3
RSNetworx
Network manager software (Catalog No. 9357-DNETL3). Similar to DeviceNet Manager software.
Server
The device that responds to a message from a client device. The Server’s response may cause it to return a message to the client. Applies to both Explicit messaging and I/O connections. With Explicit Server messaging, the PanelView terminal is the server device that responds to information requests from client devices. See Client.
Strobe
Messaging that involves an output message broadcast by the master to all slaves configured for this type of messaging. Each slave responds with an input message. The output message has one bit of data for each slave. The input message is from 0 to 8 bytes long. Also known as Bit-Strobe. The PanelView does not support this type of mess aging.
UCMM
Acronym for Unconnected Message Manager. The UCMM provides for the dynamic establishment of Explicit Messaging Connections. Many simple devices do not have UCMM capabilities and may be referred to as group 2 only server d evices.
