Using the Onboard Editor to Create Messages 2–11 Send to Slave If you enter a slave address number, the message is sent to the slave each time it is triggered. However, in Message/Variable/Slave mode, a slave address sent with the message trigger overrides this attribute. Important: To send any message to a slave, Port Use for the RS-232 or RS-485 port must be set to DL Slave. If the AutoRepeat attribute is active, the message is sent to the slave each time it repeats.
2–12 Using the Onboard Editor to Create Messages AutoClear Activating this attribute tells the DL40 Plus to clear the message from the display after the Wait Time for the message has expired, even if no other messages are triggered. This value applies only to the lines used by a single message. For example, if this message uses line 2 only, then line 2 is cleared. Lines 1, 3 and 4 remain unchanged. Important: AutoClear de-energizes the alarm relay only if the message cleared had energized the relay.
Using the Onboard Editor to Create Messages 2–13 Energize Relay Activating this attribute displays the message and energizes the display’s alarm relay whenever the message is triggered. The alarm relay will not de-energize even after the Wait Time has expired.
2–14 Using the Onboard Editor to Create Messages Hide Message This attribute suppresses the message from displaying on the DL40 Plus but does send it to a slave display, printer, or place it on the Historical Events Stack. The other attribute settings for the message determine its destination(s). For example, assume the Hide message, Print message and Send to Slave 2 attributes are enabled.
Using the Onboard Editor to Create Messages 2–15 Slave Message Echo Relay This attribute sends the energize relay command to the DL40 Plus or DL50 slave addressed in the Send message to slave number attribute. These commands are sent in addition to any specified message text.

7–4 Parallel Port Communications Selecting Binary or BCD Data The Parallel port uses either the Binary or Binary Coded Decimal (BCD) numbering system to transfer message numbers and [CTRL][V] (formatted) variables. It uses BCD or ASCII for [CTRL][W] (unformatted) variables. Select a data format using the Onboard Editor or the Offline Programming Software. The numbering system you use is usually based on the format used by your controller.
Parallel Port Communications 7–5 Using BCD Data Input You can use the 16 data lines to input BCD data. The BCD numbering system uses a group of four binary digits to represent a single decimal digit. The following table shows the BCD value of each data line. Data Line D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 Data Line Value 8000 4000 2000 1000 800 400 200 100 80 40 20 10 8 4 2 1 For example, assume the following logic levels appear for each data line.
7–6 Parallel Port Communications Logic Voltage Levels Each parallel input interprets two voltage levels: ON or OFF. There is also a third state which should be avoided, an indeterminate state. The indeterminate state occurs when the voltage is between the ON voltage range and the OFF voltage range. The table below lists the voltage levels and their logic values. Voltage Range 0 – 0.8 VDC 0.8 – 3.5 VDC 3.
Parallel Port Communications Message/Variable/Slave Run Mode 7–7 This section shows the type of triggering operations you can perform in Message/Variable/Slave Run mode. Trigger Messages You can trigger messages using the: • Parallel port • Keyboard port • RS-485 port Send Variables to be included in a Message Your controller can include variables with the message trigger. Up to 10 full word variables can be sent with the message trigger.
7–8 Parallel Port Communications Override Slave Address Selected as a Message Attribute The Message/Variable/Slave Run mode allows runtime override of the slave address specified in the “Send to Slave” message attribute. To send a message to a slave, Port Use of the RS-485 or RS–232 Port must be set to DL Slaves. Triggering Rules • • • • Optional slave address must always precede the message number. Up to 10 variables are addressable within a message. Variables must always follow the message number.
Parallel Port Communications 7–9 The strobe line states specify the type of data on the data lines.
7–10 Parallel Port Communications • If [CTRL][W]s are BCD (4 bit) variables, the [CTRL][W] in the second position would be sent in the high nibble (4 bits) of the high byte of Variable 4; the [CTRL][W] in the second position would be sent in the low nibble of the high byte of Variable 4. The low byte of the Variable 4 would be ignored (unless the message contained more BCD variables). Message List Run Mode This section shows operations you can perform in Message List Run mode.
Parallel Port Communications 7–11 Send Message to Slave Address Selected as a Message Attribute To send a message to a slave, Port Use of the RS-485 or RS–232 port must be set to DL Slaves. If the message’s Print attribute is set, the message will be printed once for each time it is displayed or redisplayed. Set the Port Use for the RS–232 port to Printer. In the Message List Run Mode, messages are continually being displayed by the DL40 Plus.
7–12 Parallel Port Communications Sampling While the DL40 Plus is in Run or Debug mode, it regularly monitors the 20 lines on the parallel port. Input data is only considered valid when all lines remain unchanged for the time specified by Data Hold Time in the Triggering Port Setup. You must insure that any data sent to the DL40 Plus is held stable for at least as long as the Data Hold Time.

8–4 Remote I/O Communications Remote I/O Terminology The following terms are used in this chapter: Acknowledge Bit Set by the DL40 Plus whenever the MSG ACK Push Button (on the front panel) is pressed after the message has run and the Acknowledge Attribute for the message is set. An operator has physically acknowledged a message triggered by the PLC. Add/Delete Bit (only for Message List Run Mode) Bit Set = adds Message Number (in word 1) to Message List.
Remote I/O Communications 8–5 Handshake Bit Tells the sender (either the DL40 Plus or the PLC) that the Image Table (either Output or Input) was received. Handshaking is selected by setting the Handshake DIP switch on the back of the unit. See page 8–16 for a description of handshaking. Hour-Minute-Second/Month-Day-Year Each is a 2 digit BCD number with time or date data returned to a PLC. Length of Message List Applies only in Message List run mode.
8–6 Remote I/O Communications Message Number (Message List Run Mode) Output Image Table or Block Transfer Write - number of message to be triggered on the DL40 Plus. Output Image Table or Block Transfer Write - number of message to be added/deleted to/from the message list.
Remote I/O Communications 8–7 Slave Address Slave address for Message/Variable/Slave run mode. Data is in same format as message number. Variable data cannot be used.

Remote I/O Communications Physical vs. Logical Addressing 8–11 DL40 Plus displays communicate with PLC controllers and Remote I/O scanners and sub-scanners as if they were a Remote I/O rack. The DL40 Plus is compatible with all Allen-Bradley scanners that support Remote I/O. The DL40 contains all the necessary electronics to connect directly to the Remote I/O cable linked to a PLC, scanner, or sub-scanner. A sub-scanner may be used with any PLC 5/15.
8–12 Remote I/O Communications The table below lists the number of separate chassis or devices the scanner can support and how much I/O it can address. Note: For any application, the total of all the I/O used by each device (I/O rack, drive system, or DL40 Plus) connected to the cable gives the number of full racks of I/O being supported by the scanner or sub-scanner for that application.
Remote I/O Communications Triggering Messages 8–13 With the Remote I/O version of the DL40 Plus, messages are normally triggered from a PLC connected to the DL40 Plus. However, messages can also be triggered via the Keyboard port, the RS-485 port or the RS-232 port. DIP Switch 2-4 enables or disables Block Transfers.
8–14 Remote I/O Communications Returning Data to the PLC The DL40 Plus returns two types of data to a PLC: • ASCII Input data • Clock/Date data ASCII Input Data The DL40 Plus returns ASCII Input data during the PLCs I/O scan as part of the Input Image Table or Block Transfer Read Data Table. This happens automatically unless you request that Clock/Date data be returned. You can only input ASCII Input Data using the Keyboard port. This data is cleared after one scan or read.
Remote I/O Communications Sending Variables 8–15 When variables are sent, all [CTRL][V] (formatted) variables must be sent first followed by [CTRL][W] (unformatted) variables. Note: ^W means the same as [CTRL][W].
8–16 Remote I/O Communications Handshake Bit The Handshake Bit tells the sender (either the DL40 Plus or the PLC) that the Image Table (either Output or Input) was received. For complex system configurations, there may not be enough time to insure that data is received by the PLC. You can use the Handshake feature to make sure that data is not lost. When activated, the Handshake feature holds data until the DL40 Plus receives acknowledgment from the PLC that it has received the data.
Remote I/O Communications Message/Variable/Slave Run Mode 8–17 In the Message/Variable/Slave run mode you can: • trigger single messages through a PLC using the Remote I/O port • send variables to be included in a message • insert ASCII input data into a message • return ASCII input data to a PLC • return the message number of the message being run to a PLC • send Real Time Clock or date data to a PLC • place messages on Historical Events Stack • require handshaking between DL40 Plus and PLC • override s
8–18 Remote I/O Communications Inserting ASCII Input Data in a Message Use the Keyboard Port to input ASCII data intended for display. • A request for ASCII Input data can be placed in a message by inserting a [CTRL][X]. • A maximum of l20 ASCII characters can be requested for each message triggered using Discrete I/O or Block Transfer Write. • Requests for ASCII data can be strung together to form inputs with a maximum of 20 ASCII characters.
Remote I/O Communications 8–19 Placing Messages on Historical Events Stack Triggered messages and variable data can be placed on the 16 Kbyte Historical Events Stack. The stack contents can be viewed/printed: • in chronological order • by number of occurrences Handshaking Between DL40 Plus and PLC Handshaking tells the sender (either the DL40 Plus or the PLC) that Image Table Data was received.

Remote I/O Communications 8–23 Triggering a Message Using a Block Transfer Write Message/Variable/Slave Run Mode - Block Transfer Write Length can be 3 to 13 words. If Length is set to 0, a default length of 13 will be used. The DL40 Plus always interprets the last word as a slave address. If more than 13 words are sent, the DL40 Plus interprets the thirteenth word as a slave address and ignores the rest. Note: Word 13 = 0 tells the DL40 Plus to use the slave address selected as a message attribute.
8–24 Remote I/O Communications Return Message Number and ASCII Data (Block Transfer Read) The following shows the format of block transfer data returned to the PLC in Message/Variable/Slave run mode. This data may include both the message number and message text. If Block Transfer Read Length is set to 0 in the PLC program, the DL40 Plus returns 12 words.
Remote I/O Communications Message/Variable Run Mode 8–25 Message/Variable run mode can be selected using the Onboard Editor or the Offline Programming Software. It is the same as the Message/Variable/Slave run mode except: • You cannot override the slave address selected as a Message Attribute. • Your PLC can send up to the equivalent of 6 (not 5) full word variables if using discrete I/O.
8–26 Remote I/O Communications Message List Run Mode In Message List run mode you can: • Trigger a single message through a PLC via Remote I/O port • Create a list of messages that are continuously displayed • Place messages on the Historical Events Stack • Send a message to the slave address selected as a message attribute • Insert ASCII data in a message • Return ASCII input data to a PLC • Return the message number of the displayed message to a PLC • Send real-time clock or date data to a PLC Creatin
Remote I/O Communications 8–27 Sending Messages to Slave Address Selected as a Message Attribute To send any message to a slave, set the Port Use of the RS-485 or RS-232 Port to DL Slaves. See Chapter 6, Serial Port Communications, for more information. Note: If the message’s Print attribute is set, the message is printed once each time it is displayed or redisplayed. The RS-232 port must be set to Printer.

8–30 Remote I/O Communications Adding or Deleting Messages using a Block Transfer Write The following shows the format of a discrete I/O message trigger in the Message List run mode. If Block Transfer Write Length is set to 0 in your PLC program, a default length of 2 is used. Block Transfer Write File (Any rack size) Add/Delete Bit WORD 0 17 16 15 14 Priority Message Number WORD 1 Message Number Messages can be added or deleted while priority messages are triggered.
Remote I/O Communications 8–31 Return Clock or Date Data to PLC (Block Transfer Read) The following shows the format of block transfer clock data returned to the PLC from the DL40 Plus. If Block Transfer Read Length is set to 0 in the PLC program, the DL40 Plus returns 2 words.
8–32 Remote I/O Communications Bit Trigger Run Mode In Bit Trigger Run Mode you can: • trigger a message by sending a bit trigger table • return the message number of the message being run to a PLC • place messages on the Historical Events Stack • send messages to the slave address specified as message attribute • insert ASCII data in a message • send real-time clock or date data to a PLC Triggering a Message by Sending a Bit Trigger Table It takes only a single bit (set) to trigger a message.
Remote I/O Communications 8–33 Sections of a Bit Trigger Table The Bit Trigger table has 3 sections (all sent with a single transfer): • Priority Message Number • Priority • Round Robin Priority Message Number Section When a priority message trigger is received (via Remote I/O, RS-485, RS-232, or Keyboard Port), it is queued as in the Message/Variable/Slave run mode. After the current message runs, priority messages in the queue run.
8–34 Remote I/O Communications Round Robin Section Messages with trigger bits set in this section are run after the priority message and all messages in the Priority Section with bits set have run. The DL40 Plus runs through this section displaying messages. After the last message in this section is displayed, the DL40 Plus returns to the first message (in this section) and starts again. Messages continue to run until an updated Bit Trigger Table is sent.
Remote I/O Communications 8–35 Bit Trigger Table The Bit Trigger Table has 2 sections, the Priority section and the Round Robin section. With 1/4 rack, Bit Trigger Table must be either priority section or round robin section. The length (in words) of the Priority Section is set in the Offline Programming Software. The length of the Round Robin Section is what is left over (total table length minus the Priority Section length minus 1).
