28 Selecting Your Hardware Components European Union Directive Compliance If this product has the CE mark it is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives.
Selecting Your Hardware Components Overview of Your Modular Control System The basic modular controller consists of a chassis, power supply, processor (CPU), Input/Output (I/O modules), and an operator interface device for programming and monitoring. The figure below shows typical hardware components for a modular controller.
30 Selecting Your Hardware Components Principles of Machine Control You enter a ladder logic program into the controller by using the software. The logic program is based on your electrical relay print diagrams. It contains instructions that direct control of your application. With the ladder logic program entered into the controller, placing the controller in the Run mode initiates an operating cycle.
Selecting Your Hardware Components Selecting Modular Processors 31 SLC 500 modular processors are designed to meet a wide range of applications, from small stand-alone to large distributed systems and from simple to complex applications. Processor Features Memory size - The SLC 500 modular processors memory is user configurable for either data storage or program storage. Memory size is 1 K...64 K. I/O points - The SLC 5/01 processor supports addressing of up to 3940 I/O.

Also include the power consumption of any peripheral devices that may be connected to the processor other than a DTAM or PIC device—the power consumption of these devices is accounted for in the power consumption of the processor. Chassis Number Slot Number 1 Cat. No.
40 Selecting Your Hardware Components Selecting Enclosures The enclosure protects the equipment from atmospheric contamination. Standards established by the National Electrical Manufacturer’s Association (NEMA) define enclosure types, based on the degree of protection an enclosure will provide. Use a fan to circulate the air of sealed enclosures that use convection cooling to dissipate heat. Select a NEMA-rated enclosure that suits your application and environment.
Selecting Your Hardware Components 41 1747-UIC USB to DH485 Interface Converter For communication with an SLC 5/01 through SLC 5/05 processor, you can connect the 1747-UIC interface between the computer’s USB port and the SLC controller. The 1747-UIC interface features an RS-232 port for communication with SLC 5/03 and later processors and an RS-485 port for communication with SLC 5/03 and previous processors.
42 Selecting Your Hardware Components Selecting a Memory Module for the SLC 5/01 and SLC 5/02 Processors You can plug these optional EEPROM (Electrically Erasable Programmable Read Only Memory) memory modules into the SLC 500 controller. With a memory module, you can: • save the contents of the processor RAM for storage purposes. • load the contents of the EEPROM memory into the processor RAM.
Selecting Your Hardware Components 43 Memory Backup for the 1747-L511, SLC 5/01 Processor The curve below illustrates the ability of the memory back-up capacitor to maintain the contents of the RAM in a 1747-L511 processor. To back up the memory for a longer period of time, a lithium battery, catalog number 1747-BA, is required.
44 Selecting Your Hardware Components programmer. The 1747-M15 Series B adapter socket is required for use with the memory module (catalog number 1747-M13). ATTENTION Make sure the adapter is inserted properly in the programming equipment or damage could result. See the table below for details on the Flash EPROM and adapter socket. Memory Module Compatibility Use with this processor type Cat. No.
Selecting Your Hardware Components 45 • The program size cannot exceed the processor memory size. For instance, an SLC 5/01 4 K processor can burn an EEPROM for a SLC 5/01 1 K processor as long as the program does not exceed 1 K. • The I/O and chassis configuration of the burning processor does not have to match the I/O configuration of the program being burned. • You do not have to enter the Run mode before burning an EEPROM.
46 Selecting Your Hardware Components Selecting Isolation Transformers If there is high frequency conducted noise in or around your distribution equipment, use an isolation transformer in the ac line to the power supply. This type of transformer provides isolation from your power distribution system and is often used as a step down transformer to reduce line voltage. Any transformer used with the controller must have a sufficient power rating for its load.
Selecting Your Hardware Components Special Considerations 47 The recommendations given previously provide favorable operating conditions for most controller installations. Some applications may involve adverse conditions, such as excessive line voltage variations and/of excessive noise, as described below. Additional measures can be taken to minimize the effect of these conditions.
48 Selecting Your Hardware Components when such loads are connected as output devices or when connected to the same supply line that powers the controller. Lack of surge suppression on inductive loads may contribute to processor faults and sporadic operation. RAM can be corrupted (lost) and I/O modules may appear to be faulty or reset themselves. For extremely noisy environments, use a memory module and program it for auto-loading on processor fault or power cycle for quick recovery.

Selecting Your Hardware Components 51 Suitable surge suppression methods for inductive ac load devices include a varistor, an RC network, or an Allen-Bradley surge suppressor. These components must be appropriately rated to suppress the switching transient characteristic of the particular inductive device. For inductive dc load devices, a diode is suitable. A diode, catalog number 1N4004, is acceptable for most applications. A surge suppressor can also be used. See the table on page 49.
52 Selecting Your Hardware Components Transient Pulse Current Transient (I) (On-State Load Current) Duration of Transient (T) Time To reduce the possibility of inadvertent operation of devices connected to transistor outputs, adhere to the following guidelines: • Either ensure that any programmable device connected to the transistor output is programmed to ignore all output signals until after the transient pulse has ended, • Add an external resistor in parallel to the load to increase the on-state lo
Selecting Your Hardware Components EXAMPLE 53 Increasing the load current by 100 mA decreases the transient time from approximately 7 ms to less than 2.5 ms. To calculate the size of the resistor added in parallel to increase the current, use the following information: 24V = your applied voltage Need 100 mA of load current to reduce the transient to <2.5 ms. (taken from graph). R (W) = V (Volts)/I (Amps) Resistor value (Ohms) = Applied voltage (Volts)/Desired current (Amps) = 24/0.

For general installation guidelines, also refer to the requirements specific to your region. • Europe: Reference the standards found in EN 60204 and your national regulations. • United States: Refer to article 70E of the National Fire Protection Association (NFPA).
56 System Installation Recommendations System Overview Refer to the following sections when planning your system layout. Environment and Enclosure ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 m (6561.7 ft) without derating. This equipment is considered Group I, Class A industrial equipment according to IEC/CISPR Publication 11.
System Installation Recommendations 57 Hazardous Location Considerations Products marked CL1, DIV 2, GP A, B, C, D are suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous locations only. Each product is supplied with markings on the rating nameplate indicating the hazardous location temperature code. When combining products within a system, the most adverse temperature code (lowest “T” number) may be used to help determine the overall temperature code of the system.
58 System Installation Recommendations Typical Installation The figure below consists of some components that make up a typical installation. 1. NEMA-rated enclosure suitable for your application and environment that shields your controller from electrical noise and airborne contaminants. (1) (4) MCR 2. Disconnect device, to remove power from the system (2) Disconnect Device (6) (3) Isolation Transformer 3.
System Installation Recommendations IMPORTANT C 59 The 1746-C9 and 1746-C16 cables have a rigid, unbendable shrink wrap applied at the end of each connector, which provides strain relief. When using these cables, provide at least 101.6 mm (4 in.) of clearance at the side of the chassis to allow for proper bend radius of the cable.
60 System Installation Recommendations Preventing Excessive Heat For most applications, normal convection cooling will keep the SLC 500 controller components within the specified operating range of 0 °C...60 °C (32 °F...140 °F). Proper spacing of components within the enclosure is usually sufficient for heat dissipation. In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure.
System Installation Recommendations Grounding Guidelines 61 In solid-state control systems, grounding helps limit the effects of electrical noise due to electromagnetic interference (EMI). The ground path for the SLC 500 controller and its enclosure is provided by the equipment grounding conductor. Scrape paint off panel to insure electrical connection between chassis and grounded metal panel. Metal Panel (Must be connected to earth ground.
62 System Installation Recommendations Ground Bus Mounting Ground Bus Equipment Grounding Conductors Ground Lug Bolt - Size M5 or M6 (4.826 mm or 5.48 mm) hardware Tapped Hole Grounding-Electrode Conductor to Grounding-Electrode System Internal star washer - Size M5 or M6 (#10 or #12) • Use 2.54 cm (1 in.) copper braid or 5.2 mm2 (#10 AWG) copper wire to connect each chassis, the enclosure, and a central ground bus mounted on the back-panel.
System Installation Recommendations 63 publication 1770-4.1, and System Design for Control of Electrical Noise, publication GMC-RM001. United States: An authoritative source on grounding requirements for most installations is the National Electrical Code. Also, refer to Allen-Bradley Programmable Controller Grounding and Wiring Guidelines, publication 1770-4.1 and System Design for Control of Electrical Noise, publication GMC-RM001.
64 System Installation Recommendations Special Grounding Considerations for dc Applications using 1746-P3 (previous to revision B) This information describes special wiring considerations for the 1746-P3 power supply that is not labeled as revision (REV) B or later-. Keep wire length as short as possible. ATTENTION Any voltage applied to the 1746-P3 DC NEUT terminal will be present at the SLC logic ground and the processor DH-485 port.
System Installation Recommendations IMPORTANT 65 SLC 500 series A chassis (1746-A4, 1746-A7, 1746-A10, and 1746-A13) manufactured before November 1992 have a resistor between the logic ground and chassis ground as the drawing on the following page illustrates. This resistor could be damaged if the wiring recommendation described within the attention box above is not followed. See the figure on the following page for the location of the resistor.
66 System Installation Recommendations Determining the Date of the SLC 500 Series A Chassis The date of the chassis is found within the serial number imprinted on the chassis nameplate on the right side of the chassis. SLC 500 RACK CAT 1746 - A7 SER A ® UL SA® SERIAL NO. A7 -1195A1357 MADE IN U. S. A. Right Side Month Year Master Control Relay A hard-wired master control relay (supplied by you) provides a convenient means for emergency controller shutdown.
System Installation Recommendations 67 Whenever any of the emergency-stop switches are opened, power to input and output devices is stopped. When you use the master control relay to remove power from the external I/O circuits, power continues to be provided to the controller’s power supply so that diagnostic indicators on the processor can still be observed. The master control relay is not a substitute for a disconnect to the controller.
68 System Installation Recommendations Power Considerations Refer to the following sections regarding power. Common Power Source All chassis power supplies should have the same power source as the input and output devices. This helps reduce the chance of electrical interference due to multiple sources and grounds as well as helps maintain system integrity if power is interrupted. The processor detects the absence of power to any chassis in the system.
System Installation Recommendations 69 Grounded ac Power-Distribution System with Master-Control Relay Disc.

70 System Installation Recommendations Loss of Power Source The chassis power supplies are designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called program scan hold-up time after loss of power. The duration of the power supply hold-up time depends on the number, type, and state of the I/O modules, but is typically 20 ms...3 s.

Appendix B Setting Up the DH-485 Network The information in this appendix will help you plan, install, and operate the SLC 500 processor in a DH-485 network. This chapter also contains information that describes the DH-485 network functions, network architecture, and performance characteristics. It also covers: • • • • • • • • DH-485 network description. DH-485 network protocol. DH-485 token rotation. DH-485 network initialization. devices that use the DH-485 network.
182 Setting Up the DH-485 Network a chance to initiate message transfers. To determine which initiator has the right to transmit, a token passing algorithm is used. DH-485 Network Protocol A node holding the token can send any valid packet onto the network. Each node is allowed only one transmission (plus two retries) each time it receives the token. After a node sends one message packet, it attempts to give the token to its successor by sending a token pass packet to its successor.
Setting Up the DH-485 Network Devices that Use the DH-485 Network 183 The following SLC 500 devices support the DH-485 network.
184 Setting Up the DH-485 Network 1747-AIC Isolated Link Coupler for DH-485 The isolated link coupler, catalog number 1747-AIC, is used to connect SLC 500 family devices to the DH-485 network. The coupler provides a 6-position removable terminal block for connection to the DH-485 communication cable.

Setting Up the DH-485 Network Below is an example of a DH-485 network.
188 Setting Up the DH-485 Network Configuring the SLC 5/03, SLC 5/04, and SLC 5/05 Channel 0 for DH485 Protocol The RS-232 port (channel 0) of the SLC 5/03, SLC 5/04, and SLC 5/05 processor can be configured for DH485 protocol. Refer to your programming software user manual for software configuration information. You can connect channel 0 of the SLC 5/03, SLC 5/04, and SLC 5/05 processors to a DH485 network using the 1747-CP3 cable and a 1761-NET-AIC Advanced Interface Converter (AIC+).
Setting Up the DH-485 Network Important Planning Considerations 189 Carefully plan your network configuration before installing any hardware.
190 Setting Up the DH-485 Network Planning Cable Routes Follow these guidelines to help protect the communication cable from electrical interference. • Keep the communication cable at least 1.52 m (5 ft) from any electric motors, transformers, rectifiers, generators, arc welders, induction furnaces, or sources of microwave radiation. • If you must run the cable across power feed lines, run the cable at right angles to the lines.
Setting Up the DH-485 Network 191 Software Considerations Software considerations include the configuration of the network and the parameters that can be set to the specific requirements of the network. The following are major configuration factors that have a significant effect on network performance.
192 Setting Up the DH-485 Network Maximum Node Address Setting The maximum node address parameter should be set as low as possible. This minimizes the amount of time used in soliciting successors when initializing the network. If all nodes are addressed in sequence from 0, and the maximum node address is equal to the address of the highest addressed node, the token rotation will improve by the amount of time required to transmit a solicit successor packet plus the slot timeout value.
Setting Up the DH-485 Network Installing the DH-485 Network 193 To install a DH-485 network, you will need tools to strip the shielded cable and to attach the cable and terminators to the Isolated Link Coupler. Install the DH-485 network using the following tools (or equivalent). Description Part Number Manufacturer Shielded twisted pair cable Belden #3106A or #9842 Belden Stripping tool 45-164 Ideal Industries 1/8 in.

196 Setting Up the DH-485 Network Grounding and Terminating the DH-485 Network Only one of the link couplers at the end of the link must have Terminals 1 and 2 of the network connector jumpered together. This provides an earth ground connection for the shield of the communication cable. Link couplers at both ends of the network must have terminals 5 and 6 of the link connectors jumpered together.
Setting Up the DH-485 Network 197 Below are three options for externally powering the 1747-AIC interface. • If the link coupler is to be installed in an office environment, you can use the 1747-NP1 wall mount power supply or 1747-NP2 global desktop power supply. The link coupler would be powered through either the 1747-C10 cable or by hardwiring from the supply to the screw terminals on the link coupler.

Appendix C RS-232 Communication Interface This appendix provides an overview of the RS-232 communication interface and explains how the SLC 5/03, SLC 5/04, and SLC 5/05 processors support it. This appendix also provides information on: • RS-232 and SCADA applications. • RS-232 communication interface overview. • SLC 5/03, SLC 5/04, and SLC 5/05 processors and RS-232 communication. • SLC 500 devices that support RS-232 communication. • DF1 protocol and the SLC 5/03, SLC 5/04, and SLC 5/05 processors.
202 RS-232 Communication Interface The RS-232 channel on the SLC 5/03, SLC 5/04, and SLC 5/05 processors supports various protocols: • • • • • • Full-duplex DF1 (default) Half-duplex DF1 (SCADA) DH-485 ASCII communication DF1 radio modem Modbus RTU Master The SLC and PLC products detailed in this appendix that communicate over the RS-232 communication interface also use the DF1 serial communication protocol.
RS-232 Communication Interface SLC 500 Devices that Support RS-232 Communication 203 The SLC 500 product line has two other modules, aside from the SLC 5/03, SLC 5/04, and SLC 5/05 processors, that support the RS-232 communication interface. They are the 1746-BAS BASIC module and the 1747-KE DH-485/RS-232C interface. Both of these modules can be used with either the SLC 5/01 or SLC 5/02 processor.
204 RS-232 Communication Interface DF1 Protocol and the SLC 5/03, SLC 5/04, and SLC 5/05 Processors DF1 protocol combines data transparency (ANSI - American National Standards Institute - specification subcategory D1) and 2-way simultaneous transmission with embedded responses (F1). It is also a peer-to-peer, link-layer protocol. This means that system devices have equal access to messages being sent over the RS-232 communication interface.
RS-232 Communication Interface 205 Full-duplex (Point-to-Point) Modem Modem SLC 5/03 Processor (1747-L532) SLC 5/03 Processor (1747-L532) 1747-CP3 Cable DF1 Half-duplex Protocol DF1 half-duplex protocol provides a multi-drop single master/multiple slave network. In contrast to the DF1 full-duplex protocol, communication takes place in one direction at a time. You can use channel 0 as a programming port, or as a peer-to-peer port using the MSG instruction.
206 RS-232 Communication Interface instruction for all channel 0 system mode drivers and for channel 1 (DH-485) on the SLC 5/03 processor. Broadcast is not supported for read commands or any remote messages. Broadcast is also not supported by the SLC 5/04 channel 1 DH+ network or the SLC 5/05 channel 1 Ethernet network.
RS-232 Communication Interface 207 DF1 Radio Modem Channel 0 Driver Series C FRN 6 (FRN C/6) and later versions of operating systems OS302 (SLC 5/03 processor), OS401 (SLC 5/04 processor) and OS501 (SLC 5/05 processor) include a channel 0 system mode driver called DF1 radio modem. This driver implements a protocol, optimized for use with radio modem networks, that is a hybrid between DF1 full-duplex protocol and DF1 half-duplex protocol, and therefore is not compatible with either of these protocols.
208 RS-232 Communication Interface Channel O Configuration The Baud, Parity, Stop Bits and Error Detection selections are identical to the other DF1 drivers. Valid Node Addresses are 0...254, just like the DF1 half-duplex drivers. The primary advantage of using DF1 radio modem protocol for radio modem networks is in transmission efficiency.
RS-232 Communication Interface 209 DF1 Radio Modem System Limitations The following questions need to be answered in order to determine if you can implement the new DF1 radio modem driver in your radio modem network. • Are all of the devices SLC 5/03, 5/04 or 5/05 processors? If so, then they must all be at operating system FRN C/6 or later in order to be configured with the DF1 radio modem driver using RSLogix 500 version 5.50 or later software.
210 RS-232 Communication Interface Modbus RTU Master Communication Modbus RTU communication lets you connect the SLC 5/03, SLC 5/04, and SLC 5/05 processors to Modbus RTU slave devices for exchange of data values. For an overview of the Modbus RTU Master protocol modem, refer to the SLC 500 Instruction Set Reference Manual (1747-RM001).
RS-232 Communication Interface 211 DCD (Data Carrier Detect) - this is an input signal from the DCE that indicates a carrier signal is being received and that presumably data is to be received for forwarding to the DTE connected. Wiring Connectors for RS-232 Communication To connect Allen-Bradley devices with other devices over RS-232, you must wire the cable connectors so that communication can occur through the cabling, which provide the interface between devices.

I/O Inputs and Outputs IP address A 32-bit address assigned to hosts that want to participate in a TCP/IP internet.
278 Glossary low byte Bits 0...7 of a word. logic A general term for digital circuits or programmed instructions to perform required decision making and computational functions. manual Typically an acoustically coupled type of modem. The connection is established by a person on each end of the phone line. They then insert the handsets into an acoustic coupler to complete the connection. master control relay (MCR) A hard-wired relay that can be de-energized by any series-connected emergency stop switch.
Glossary 279 multi-master network A network in which more than one node has the ability to initiate communication and initialize the link. M0/M1 file transfer A M1/M0 file transfer is a method of moving large amounts of data between a SLC 500 processor and its scanner. It transfers files containing a maximum of 256 words and may take more than one SLC program scan to complete. negative logic The use of binary logic in such a way that 0 represents the desired voltage level.
280 Glossary offline When a device is not scanning/controlling or when a programming device is not communicating with the controller. offset A continuous deviation of a controlled variable from a fixed point. off-state current For input circuits, the maximum amount of leakage current allowed from an input device in its off-state. off-state leakage current When a mechanical switch is opened (off-state), no current flows through the switch.
Glossary 281 operating voltage For inputs, the voltage range needed for the input to be in the On-state. For outputs, the allowable range of user-supplied voltage. output device A device, such as a pilot light or a motor starter coil, that is energized by the programmable controller. output scan The controller turns on, off, or modifies the devices connected to the output terminals.
282 Glossary programming device Programming package used to develop ladder logic diagrams. protocol The language or packaging of information that is transmitted across a network. (I/O) rack An I/O addressing unit that corresponds to 8 input image-table words and 8 output image-table words. A rack can contain a maximum of 8 I/O groups for up to 128 discrete I/O. read To acquire data. For example, the processor reads information from other devices via a read message.
Glossary 283 RTB Removable Terminal Block. run mode An executing mode during which the controller scans or executes the logic program. rung A rung contains input and output instructions. During Run mode, the inputs on a rung are evaluated to be true or false. If a path of true logic exists, the outputs are made true (energized). If all paths are false, the outputs are made false (de-energized). save To save a program to a computer hard disk.
284 Glossary sourcing A term used to describe current flow between two devices. A sourcing device or circuit provides power. status The condition of a circuit or system. strobe message A strobe message is a multicast transfer of data sent by the scanner that solicits a response from each slave device. The devices respond with their data. surge current per point The maximum amplitude and duration (pulse) of current allowed for a given period of time and temperature.
Glossary 285 upload Data is transferred from the controller to a programming or storage device. UVPROM An Ultra-Violet light erasable Programmable Read Only Memory module used to back-up, store, or transfer SLC 500 programs. The SLC 5/01 and SLC 5/02 processor can only read from a UVPROM. An external PROM programmer is used to program (write to) the device. voltage category The nominal voltage used to describe the module.
