Chapter A–B 2 Product Introduction Chapter Objectives This chapter describes the features, functions and operation of the Bulletin 2705 RediPANEL Keypad Module. Features The Bulletin 2705 RediPANEL Keypad Module is an operator module that connects directly to an Allen–Bradley PLC via the remote I/O link. It provides the capability for operators to input data to and retrieve data from the PLC. It also functions as a single line message display.
Chapter 2 Product Introduction Applications The Keypad Module combines the functions of standard thumbwheel or push button devices with the built–in capabilities of a remote I/O rack. The Keypad Module communicates directly with the programmable controller via the Remote I/O link. You can install a 2705 module anywhere along that link. To the PLC, the Keypad Module looks like a hardwired remote I/O rack. The function keys and the LED output signals are programmed as discrete I/O in the PLC.
Chapter 2 Product Introduction Operator Data Input The 2705 RediPANEL Keypad Module features a numeric keypad with DELETE, ENTER, decimal and polarity keys. Using the keypad, operators can enter up to eight (8) digits (seven digits for signed numbers), which appear on the right side of the 16 character display. If an attempt is made to enter more than eight digits, only the first eight are accepted.
Chapter 2 Product Introduction 2) A combination of ASCII and numeric data. Up to 8 characters of ASCII data are displayed on the left side of the display and 8 digits of numeric data are displayed on the right side of the display. This allows you to label numeric data with text. The ASCII data can consist of either the first 8 characters of a stored message or 8 characters sent from the PLC controller.
Chapter A–B 3 Installing the Bulletin 2705 Keypad Module Chapter Objectives This chapter lists electrical precautions and power and grounding requirements for installing the Bulletin 2705 RediPANEL Keypad Module. Topics also include selecting NEMA enclosures, the mechanical installation of the module, and connecting to remote I/O links and to scanner modules.
Chapter 3 Installing the Bulletin 2705 Keypad Module Grounding Grounding is an important safety measure in electrical installations.

Chapter A–B 7 Programming Chapter Objectives This chapter describes the process of creating a program for the Bulletin 2705 RediPANEL Keypad module. The detailed listing of the program example explains the ladder logic programming. Introduction Of Programming with the Keypad Module Applications for the Keypad Module are programmed in the Allen–Bradley PLC controller. The module itself has an on–board message editor that can create and store up to 120 single line messages.

In this instance, F1 is used to increment the accumulative value of count up counter C5:1 and initiate a MOVE instruction.
Chapter 7 Programming Triggering a Stored Message to Describe Data The Keypad Module is not only capable of displaying numeric data, but also alphanumeric messages to describe that data. These messages may be stored in the programmable controller and sent to the Keypad Module via ASCII code, or store up to 120 messages in the Keypad Module and trigger them according to their message number. The later method is the most common means of displaying messages on the Keypad Module.
Chapter 7 Programming Rung 2:2 shows how the same input, F1, which is used to move the accumulated value of the counter to the Keypad display, can also trigger a stored message. The MOVE instruction in rung 2:2, moves the constant 1 to 0:022, the word in the output image table where the Stored Message Display (SMD) number is sent to the Keypad Module. (See Figure 7.1, Input and Output Image Tables.) In this case when F1 is pressed, message number 1 ”C5.1 ACC.
Chapter 7 Programming In Figure 7.4, function key F3 is used to initiate a MOVE instruction. The MOVE instruction, moves the constant 3 to the Keypad module’s stored message word 0:022. This in turn triggers stored message number 3 “16 CHARACTER MSG.”. The second rung in Figure 7.4, Rung 2:4 uses a Greater Than/Equal To instruction (GEQ) to control the DM bit.
Chapter 7 Programming Figure 7.5 Rung 2:5 Enter Key I:020 ] [ MOV MOV Source 16 Dest Rung 2:6 F2 Function Key I:020 ] [ 11 MOV MOV Source Dest Enter Key I:020 ] [ 16 I:021 50 C5:1.PRE 69 2 0:022 2 MOV MOV Source Dest C5:1.PRE 69 0:021 69 In the example shown in Figure 7.5, rung 2:5 is used to move the value from the input image table, I:021, to counter C5.1 preset, each time the Enter key is pressed. Rung 2:6 in Figure 7.
Chapter 7 Programming Using the Destination Function to Load Multiple Timer Presets The keypad destination function can be used to load data values into multiple timer/counter presets or other PLC memory locations. The example program listed below can be used to load preset values into 17 consecutive timer presets, beginning with T4:0.PRE and ending with T4:16.PRE. Rungs 3 through 16 have been omitted to simplify the example.
Chapter 7 Programming Rungs 3–16: Would appear the same but with different timer/destination bit addresses. Rung 17: Destination bit I:024/00 is “ON” when the keypad operator enters destination number “17”. All other destination bits are “OFF”. The ENTER bit I:020/16 prevents data from being moved until the keypad operator enters a new preset for T4:16. The MOVE instruction takes the integer data in I:021 and transfers it to T4:16.PRE.
Chapter 7 Programming Using PLC-5 Controllers and a Sub I/O Scanner with Keypad Modules A 1771–SN, Sub I/O scanner may be used with a PLC–5 family processor when the application requires more remote devices than that processor can accommodate. The sub I/O scanner module may be used to communicate to as many as 16 additional remote I/O devices. The 1771–SN Sub I/O scanner may be located in the same rack as the PLC–5 (the local rack), or in any space of the remote racks supported by the processor.
Chapter 7 Programming The ladder diagram in Figure 7.6 is a simple programming example showing Bidirectional Block Transfers between a sub I/O scanner and PLC–5. Figure 7.6 PLC–5 Block Transfer BTR Enable Bit N10:0 ]/[ 15 BTW Enable Bit N10:5 ]/[ 15 BTR BTW Enable Bit Enable Bit N10:0 ]/[ 15 N10:5 ]/[ 15 Read from Sub–Scanner to the PLC–5.
Chapter 7 Programming be reflected in this file. Therefore, all your input or output addresses for these remote devices will be elements of this file. • LENGTH is the number of words the sub I/O scanner is transferring. The number entered will be equal to 8 words (reserved for sub I/O scanner utility functions) plus 2 words for each 1/4 rack of I/O the sub I/O scanner will be communicating with.
Chapter 7 Programming Figure 7.
Chapter 7 Programming In the programming example shown in Figure 7.7, you’ll notice the length has been set for (12), 8 words for the block transfer utility functions and 4 words for the Keypad Modules configured for 1/2 rack. The DATA FILE for the block transfer read instruction begins at N11:0. This means the addresses in the ladder logic, for the keypad input, will begin with N11:8/00. The DATA FILE for the block transfer write instruction begins at N12:0.
Chapter 7 Programming PLC-2 Programming Example The following pages contain a PLC–2 example program which utilizes many of the functions of the Keypad Module. Keep in mind that this program is simply an example - your applications may or may not fit this structure.
Chapter 7 Programming PLC–2 Programming Example The example program below is explained on the following pages. We present the program here (and on the next page) in its entirety for your reference. Note – Block transfer is only required when using the 1771–SN sub I/Oscanner Block transfers allow communications between the sub–scanner and PLC. Block transfers are not required for any other type of scanner module.

Chapter 7 Programming When to Use the Handshake Mode RediPANEL Modules have a standard TIMED feature that holds all push button depressions for a minimum of 100 milliseconds to allow the PLC controller to read the depression during its scan cycle. No special programming is needed for this function. Most system configurations can use this feature to help insure data capture of a push button depression. As a general guideline, handshaking is not required. The few cases where it is required would be: 1.
Chapter 7 Programming With the handshake feature enabled and the handshake rung in the user’s program, the RediPANEL module holds all function key input signals high for a minimum of one complete PLC program scan. It keeps the signal(s) high for one complete cycle of the handshake input bit. The handshake input and output signals will continuously toggle independent of any function key closures. This ensures that the handshake function is operational even if no function keys have been pressed.

Chapter 7 Programming SLC–5/02 Programming Example In the following example, a Bulletin 2705 RediPANEL displays stored messages. An alarm, connected to an output module, signals when communications with the RediPANEL are lost. The system consists of: • SLC–5/02 Processor (Catalog No. 1747–L524) in slot 0 • Remote I/O Scanner (Catalog No. 1747–SN) in slot 1 • Output Module (Catalog No.
Chapter 7 Programming The scanner input file is shown below. The output file is similar, it is addressed O:1.0 to O:1.3.

Chapter 7 Programming Address Conversion The addresses for the Input and Output files are provided in an octal format. You must convert the bit addresses to decimal to accommodate the SLC–5/02. Refer to the following. Bit Address Scanner Configuration Decimal 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 SLC–5/02 Octal 1 2 3 4 5 6 7 10 11 12 13 14 15 16 17 PLC–5 The BAUD rate is 115.2K. DIP switch 1 should be in the OFF position, DIP switch 2 should be ON.
Chapter 7 Programming Example Program The example program is shown below. Each time a function key is pressed on the RediPANEL, its associated message is displayed. This program also monitors the scanner’s Enabled Device Fault bit (M1:1.0/0). If communications are lost, an alarm is activated. If the communications attempted and Enabled Device Fault bits are set to 1, activate the alarm. If function key 1 is pressed (bit 8 of input word 0), T4:0 preset is moved to the display.
Chapter A–B 8 Maintenance and Troubleshooting Chapter Objectives This chapter describes how to use the Comm/Fault LED indicators, and explains the power–up sequence error message display, plus addresses basic troubleshooting questions on the RediPANEL Keypad Module. Using the Comm/Fault LED Indicators Two LED indicators are located on the right top corner of the module a green LED labeled COMM and a red LED labeled FAULT.
Chapter 8 Maintenance and Troubleshooting The COMM Indicator Any communication faults or errors are indicated by the green LED labeled COMM. The LED can be in one of three states: 1. OFF 2. ON 3. Blinking COMM OFF When COMM indicator is OFF: 1. The module is not receiving input power. 2. The module is operating correctly, but no communications is occurring at this time. Check the Remote I/O Link wiring. 3. The module is the last rack, but the DIP switch indicating this state is not in the OFF position.
Chapter 8 Maintenance and Troubleshooting • • • Have you changed the settings of any of the DIP switches? New DIP switch settings will not be acknowledged until power is recycled. Refer to Chapter 5. If you do not have the communications LED ON and all of your DIP switches seem correct – check the remote I/O link wiring. You may need to reverse the blue and clear wires. If your 120 Volt AC is intermittent be sure your 120/240 Volt AC selectable switch is set properly.
