Setting up Communications using PanelBuilder

Setting up DeviceNet com munications for an application requires:

• selecting a DeviceNet terminal when creating the application.

• configuring communication parameters for the terminal on the DeviceNet link.

Selecting a DeviceNet PanelView Terminal

Select a DeviceNet terminal for a PanelView application from:

• New Application dialog when creating a new application or

• Terminal Setup dialog when converting an application initially created for another terminal.

Any catalog number ending with 10 is a DeviceNet terminal.

Publication 2711-6.0.4

Configuring DeviceNet Communications

DeviceNet communication parameters are accessed from the Terminal Setup dialog. To open the Terminal Setup dialog, select

Application>Terminal Setup.

1. Click the Comms. Setup button from the Terminal Setup dialog.

2. Under Terminal, edit the following parameters.

default value which indicates that no input I/O data exists in the application. Size must match configuration in Master device.

Specify the number of words (0 to 64) that are received by the PanelView from the scanner with each I/O message. 0 is the default value which indicates that no output I/O data exists in the application. Size must match configuration in Master device.

Publication 2711-6.0.4

4. Edit the following parameters:

Specify To:

Provide a delay between scans of the Explicit-Client tags. Enter a value of 0 to 65535 milliseconds. The default is 500 msec. This time delay is inserted between each full scan of

Interscan Delay

Bus-off Interrupt

Explicit-Client tags in the current screen context. Note: Time delays of less than 500 msec should be carefully

considered since the Explicitly-Client mode will generate low priority network messaging at this interval.

Specify what occurs when a Bus-off Interrupt occurs on the network:

• Hold in Reset holds the PanelView and waits for communications to be reset.

• Reset and Continue Communications resets DeviceNet communications and attempts to re-establish the communications link (if possible).

5. Click OK to exit and return to the Terminal Setup dialog.

Publication 2711-6.0.4

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

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.
