Intended Audience

Conventions Used

Related Publications

No special knowledge is needed to enter or edit messages. However, since the Dataliner message display must be connected to peripheral equipment, we assume you are familiar with communication terminology, especially when using the Remote I/O version with a PLC.

The following conventions are used in this manual:

•All menus and screens reproduced in this manual are approximate renderings of what you will see on your terminal screen. Allen-Bradley reserves the right to make minor modifications to any menu or screen to help improve performance.

•A symbol or word in brackets represents a single key that you press. These include keys such as [A] or [Delete]. Since the Dataliner can be programmed with a variety of keyboards or

terminals, the printing on your keyboard may be different from the symbol or word indicated in brackets. This manual uses to

specify the carriage return function of a keyboard. On your keyboard this may correspond to an [ENTER], , or [Return] key.

•The up caret, ^, may be used in place of the [CTRL] where space requires. For example, ^W means the same as [CTRL][W]. This means you should press [CTRL] and [W] keys simultaneously.

•DL40 Plus refers to the Dataliner DL40 Plus Message Display

The DL40 Plus is available in a 2- or 4-line configuration (capable of displaying 20 characters per line) with either Remote I/O or Parallel port communication options.

Remote I/O Version

The Remote I/O version enables two-way communications with the Allen-Bradley family of PLCs and SLCs. A remote I/O version of the DL40 Plus can appear to the PLC or SLC as any size I/O rack (1/4, 1/2, 3/4, or full).

Parallel Port Version

The Parallel Port version receives message number triggers, slave addresses, and variable data from a PLC or SLC output module via 16 data lines and 4 strobe lines (indicating the type of data).

1±2 Overview of the DL40 Plus

RS-485/RS-232 Communications

Both the Remote I/O and Parallel Port versions have RS-485 and RS-232 ports. You can configure these ports for Programmer, DL Slave or Open Protocol communications (see table below). Port settings are modified through the Ports menu in the Offline Programming software or the Onboard Editor. You select a communication option under the Port Use submenu.

The RS-232 port always communicates with the Offline

Programming Software regardless of the configured mode. Open

Protocol or DL Slave operation can occur on either the RS-232 or

RS-485 port.

If the RS-485 port is configured for Open protocol, you cannot configure the RS-232 port for the same protocol. Instead, an information message reports an invalid port configuration.

Message Support

The DL40 Plus stores messages of varying length. Each message is identified by a unique message number from 1 to 9999. Messages are placed in an internal memory queue when triggered by a command from your control system. They are then run according to attributes selected in the DL40 Plus.

The DL40 Plus can display a wide variety of characters and symbols, including:

•Uppercase letters

•Lowercase letters

•Punctuation

•Special characters from the extended ASCII character set

•English character set (default)

•International character set ISO 8859±1

Onboard Editor

With the Onboard Editor you can create or edit messages, select message attributes, and set options and variable formats using a standard IBM PC keyboard. The Keyboard port is located on the rear panel of the DL40 Plus.

Send ASCII Data to a PLC via Remote I/O Link

Using Remote I/O communications, you can send ASCII data to a PLC. Attach an IBM compatible keyboard to the DL40 Plus and you can enter part numbers, badge numbers, passwords, and similar information as required. The DL40 Plus processes and displays the information, and then sends it to the controller.

You can establish similar communications over an RS-232 or

RS-485 link.

Communicate with any Programmable Controller (Parallel Port Version)

The DL40 Plus accepts information from any programmable controller over a total of 20 input lines (16 data and 4 strobe lines).

Parallel Port versions of the DL40 Plus have an isolated 12 VDC supply output that can be used to power outputs that pull data and strobe lines high.

Backup Operations

Archive DL40 Plus application files in the Offline Programming Software (Catalog No. 2706-LSW) by uploading or downloading files between a computer and DL40 Plus displays.

Publication 2706-6.1

1±8	Overview of the DL40 Plus

Historical Events Stack

The Historical Events Stack records the occurrence and sequence of some or all messages and logs variable data values that have been triggered and/or displayed. The 16K bytes of stack memory holds about 1,000 events. You can view information in chronological order or by frequency of occurrence, or print the record.

Clock Operations

A real-time battery-backed clock keeps accurate time even when power is removed from the unit. The DL40 Plus can display the current time and/or date in either AM/PM or 24-hour military format.

Note: The date function is year 2000 compliant.

Date and time information can be displayed as part of any triggered message, and passed on to a PLC. You can also dateor time-stamp events as they are recorded in the Historical Events Stack.

Set the DL40 Plus internal clock using the front panel menus, a keyboard connected to the Onboard Editor, a PLC, or the Offline Programming Software.

RS-232 and RS-485 Ports

The DL40 Plus has both an RS-232 and RS-485 port.

Use the RS-232 port to:

•upload or download message files from a computer

•trigger messages via Open protocol (ASCII triggering)

•send messages to a single slave message display

•print messages and/or the contents of the Historical Event Stack

Use the RS-485 port to:

•multi-drop upload or download message files from a computer

•trigger messages via Open protocol (ASCII triggering)

•send messages to one or more slave message displays

•input ASCII data via bar code

Publication 2706-6.1

1±9

Keyboard Port

Use the Keyboard port on the DL40 Plus to:

•edit options, messages, communication port settings

•input ASCII data to a host controller, PLC, or computer

•trigger messages using Open protocol (ASCII triggering)

Debug Mode (Parallel Port Version)

Use Debug mode to display the binary status (1 or 0 value) of the data lines and the state of the strobe lines. This mode is useful for checking the output of a programmable controller.

Auxiliary Devices

Connect a variety of useful auxiliary devices to the DL40 Plus display.

Slave Displays

Address up to 126 DL40 Plus or DL50 slave displays over an RS-485 network at distances up to 4,000 feet (1200 m) from the originating DL40 Plus. You can also control the annunciation relay on remote DL40 Plus or DL50 Series slave displays. By assigning a specific address to each slave display, you can control which slaves receive and display a given message.

Printers

Connect a serial printer to print the Historical Events Stack or a listing of the internal application file. The time and date a message was triggered can be included on the stack printout. You can also set message attributes such as sending triggered messages to a printer through the RS-232 port.

Alarms

The alarm relay activates or deactivates an external remote alarm or warning light. Individual message attributes can be set to energize or de-energize the alarm relay contacts on DL40 Plus or slave displays.

		ATTENTION: Use the DL40 Plus alarm relay for
	!	annunciation purposes only. Do not use the alarm relay
		for control applications.

Publication 2706-6.1

1±10	Overview of the DL40 Plus

Background Messages

Specify a background message that will display whenever the DL40 Plus has no other triggered messages in the queue.

Hidden Messages

Hidden messages do not appear on the DL40 Plus display or have any affect on what is being displayed. Hidden messages can be sent to a slave display, printed, or stored on the Historical Events Stack.

Embedded Variables

Messages can contain variable data. Variable values are received when the message is triggered. Incoming variable data can be binary, BCD (binary coded decimal), and/or ASCII. You can also embed time and date information in a message from the battery-backed real-time clock of the DL40 Plus.

Data Mode Selection

When using the DL40 Plus with Remote I/O or parallel input for communication, you can select two data modes:

•Binary

•Binary Coded Decimal (BCD) either signed or unsigned

Within any application, triggers and variable data can be in either form. For example, message triggers can be in a binary format, while variable data can be BCD.

Note: When using serial RS-232 or RS-485 communications, all data is in ASCII character format.

Message Chaining

Chain messages together for display in sequence. Only the first message in the chain is triggered from the host controller. Then each message in the chain can trigger the next until the complete sequence has run.
