Setting Up Your Equipment 1 Setting Up Your Equipment This chapter briefly describes hardware requirements and SLC 500t controller styles, then shows you how to set up your equipment in preparation for the exercises in later chapters.
APS Quick Start for New Users Preface Hardware Requirements To perform the tasks provided in this manual we recommend the following hardware: • • • • • 1–2 An SLC 500 modular or fixed controller with external inputs and outputs. An SLC 500 demo unit would be ideal. The programs and examples used in this manual are based on using a modular controller demo unit (catalog number 1747-DEMO 3 or 1747-DEMO 4). A compatible personal computer (PC).
Setting Up Your Equipment Controller Styles The SLC 500 comes in two different styles: modular and fixed. These styles are illustrated below. The modular controller consists of a chassis, power supply, processor (CPU), and Input/Output (I/O) modules. The fixed controller consists of a power supply, processor (CPU), and a fixed number of I/O contained in a single unit. An expansion chassis can be added to the fixed controller.
APS Quick Start for New Users Preface Setting Up a Demo Unit SLC 500 demo units are available with either a fixed controller or modular controller. This manual assumes you are using a modular controller demo unit for all the programming exercises. If you use a fixed controller demo unit, you will need to use different configuration information and I/O addresses in the exercises. This is explained later. The figure that follows shows an SLC 500 modular controller demo unit.

APS Quick Start for New Users Preface Setting Up a Field-Wired Controller The details of installing and wiring the controller and external input/output devices are beyond the scope of this manual. If you are using a field-wired fixed or modular controller, refer to the Installation and Operation Manuals, catalog number 1747-NI001 (fixed controllers) and publication number 1747-6.2 (modular controllers), for information on installation and wiring of the controller and external input/output devices.
Setting Up Your Equipment Connecting the Controller to a Personal Computer To connect the controller to a personal computer, you need a communications cable, catalog number 1747-C10, and an RS-232/DH-485 interface converter, catalog number 1747-PIC. Note This procedure does not apply to SLC 5/04 processors. For these processors, you need to connect a 1747-CP3 cable from channel 0 of the processor to the personal computer serial port, or you need to use a KT, KTX, KT2, or PCMK card. 1.
APS Quick Start for New Users Preface SLC 500 DH 485 Connector Personal Computer Interface Converter RS 232 Connector 4. ALLEN BRADLEY Insert the RS-232 connector (see figure above) of the interface converter into the serial communication port of your computer. If your computer has a 9-pin serial port, use the 9–25 pin adapter provided with the interface converter. The figure below shows a modular controller connected to a personal computer.
Setting Up Your Equipment Installing the Software Before installing the software, make sure your personal computer meets the memory and RAM requirements needed to run APS. Refer to the Advanced Programming Software User Manual for more detailed information on personal computer requirements and APS software installation. Locating the Software’s Serial Number During the installation process you are asked for the serial number of your software. The serial number you enter is used to personalize the software.

To do this, type: 1. C: and press [ENTER]. 2. If you are using the default directory, at the DOS prompt, type: CD \IPDS\ATTACH\SLC500 and press [ENTER]. If you specified a different directory path, enter that directory instead. Type: AP and press [ENTER]. The main APS menu appears. 3.
Setting Up Your Equipment Exiting the System: You can exit APS software and return to DOS by accessing the APS menu, shown above, and pressing CONFIG OFFLINE EXIT SYSTEM . CONFIG F10 APS Display Format The APS screen is divided into three areas: • • • display area message, prompt, data entry, and status lines main functions The following figure indicates what appears in these areas.
APS Quick Start for New Users Preface • Display Area: The five APS displays appear here the APS menu, offline program directory (shown here), offline monitor file, online program directory, and online monitor file. Various option windows overlay these displays, de pending on the function you are accessing. Also, the status data file and other data files, force tables, and the memory map appear in this area.
Control Basics 2 Control Basics This chapter introduces you to basic concepts essential for understanding how the SLC 500 controller operates.
APS Quick Start for New Users Preface SLC 500 File Concepts The CPU, or processor, provides control through the use of a program you create. The program you create is called a processor file. This file contains other files that break your program down into more manageable sections. These sections are: • • Program Files - provide storage and control of the main program and subroutines. Data Files - contains the status of inputs, outputs, the processor, timers, counters, and so on.
Control Basics Program Files Program files contain controller information, the main control program, and any subroutine programs. The first three program files are required for each processor file. These are: • File 0 - System Program This file stores the controller configuration and other system information. • File 1 This file is reserved for internal controller use. • File 2 - Main Ladder Program This file stores the main control program.
APS Quick Start for New Users Preface Data Files Data files contain the data associated with the program files. Each processor file can contain up to 256 data files. These files are organized by the type of data they contain. Each piece of data in each of these files has an address associated with it that identifies it for use in the program file. For example, an input point has an address that represents its location in the input data file.
Control Basics How External I/O Devices Communicate with the Processor The figures that follow apply to a modular controller demo unit having an input module in slot 1 and an output module in slot 3. See page 1–3 for a diagram of the slot location. To simplify the illustration, only pushbutton 0 and pilot light 0 of the external I/O are shown. Each of the external input circuits is represented by a status bit in the input data file of the processor file.
APS Quick Start for New Users Preface OUTPUT Output Module in slot 3 Output Data File 0 OUT 0 OUT 1 Pilot light 0 is wired to terminal 0. The pilot light will be energized when the processor has completed evaluation of the program and transfers the ON/OFF status to the outputs. address O:3 data 0000 0000 OUT 2 OUT 3 OUT 4 4 OUT 5 OUT 6 Status bit 0 corresponds to terminal 0 of the output module in slot 3.
Control Basics Similarly, output addresses have the form O:e/b where O= Output data file := Element or slot delimiter e= Slot number of the output module /= Bit or terminal delimiter b= Terminal number used with output device Examples: I:1/0= Input, slot 1, terminal 0 I:2/0= Input, slot 2, terminal 0 O:3/0= Output, slot 3, terminal 0 O:3/7= Output, slot 3, terminal 7 O:0/7= Output, slot 0, terminal 7 (fixed controllers only because of slot 0) I:0/4= Input, slot 0, terminal 4 (fixed controllers only becaus
APS Quick Start for New Users Preface APS Display of Instructions/Addresses APS displays I/O addresses as shown below. When you enter an XIC instruction (defined later) and the address I:1/0, APS will display the address with the instruction as follows: I:1 ] [ 0 Explanation: Input data file, slot 1 I:1 ] [ 0 Terminal 0 XIC instruction Ladder Logic Concepts As we mentioned earlier, the program files you create contain the program used for your controlling application.
Control Basics The figure below shows a simple 1-rung ladder program. The rung includes two input instructions and an output instruction. Note, in the example below each instruction has a name (Examine if Closed), a mnemonic (XIC), and an address (I:1/0). Input Instructions Output Instruction XIC XIO OTE I:1 ] [ 0 I:1 ]/[ O:3 ( ) 0 1 XIC = Examine if Closed XIO = Examine if Open OTE = Output Energize Address I:1/0 Address I:1/1 Address O:3/0 A simple rung, using bit instructions.
APS Quick Start for New Users Preface Logical Continuity During controller operation, the processor evaluates each rung, changing the status of instructions according to the logical continuity of rungs. More specifically, input instructions set up the conditions under which the processor will make an output instruction true or false. These conditions are: • • When the processor finds a continuous path of true input instructions in a rung, the OTE output instruction will become (or remain) true.
Control Basics The Processor Operating Cycle The diagram below indicates the events that occur during the processor operating cycle. This sequence is repeated many times each second. Event Input Scan Description F8 0 Input Data File address data I:1 0001 1 The status of external input circuits is read. The input data file is updated with this information. activated Program Scan I:1 ] [ 0 1 Output Data File Output Scan The ladder program is executed.
Creating a Processor File 3 Creating a Processor File In this chapter you create a processor file. The tasks you will perform: • • • • • • • • For modular controllers: Make a record of the processor module catalog number, the chassis catalog number(s), the I/O module catalog numbers, and the slot locations of I/O modules. For fixed controllers: Make a record of the controller catalog number (and I/O module catalog numbers and slot locations if you are using the 1746-A2 expansion chassis).
APS Quick Start for New Users Preface Configuration of SLC 500 Controllers The following paragraphs briefly describe SLC 500 controllers and indicate the location of catalog numbers on the devices. This information will help you when you create a processor file and enter the specific controller configuration that will run the file. To make the best use of this manual, you should have access to an SLC 500 Demonstration Unit, which includes completely wired external inputs and outputs.
Creating a Processor File Slot Numbers Note that slot numbers are indicated in the figure above. In fixed controllers, slot 0 applies to the processor and fixed I/O points; slots 1 and 2 apply to I/O modules located in the expansion chassis. In modular controllers, slot 0 is always reserved for your processor module; the remaining slots apply to the various I/O modules you have inserted.
APS Quick Start for New Users Preface Catalog Number Location - SLC 500 Modular Controllers Processor (CPU) Modules Label for Processor Catalog and Serial Number I/O Modules SLC 500 CAT 1747-L _ _ _ Catalog Number 1746 _ _ _ Processor Catalog Number The catalog number and serial number for I/O modules also appears on the side of the module.
