A Control System is the electronic equipment needed to control a particular process. It may include everything from a process control computer, if one is used, to the factory computer, down through the PCs (and there may be many of them networked together), and then on down through the network to the control components: the switches, stepping motors, solenoids, and sensors which monitor and control the mechanical operations. Process Control Computer Factory Computer PCs PC PC PC Control Components A Control System can involve very large applications where many different models of PC are networked together or it could be an application as small as a single PC controlling a single output device. 2 Section 1 Introduction Position Control System Position Control Unit Input Unit PC Signal line for Servomotor driver control Handheld Programming Console Power source Control panel Control switch Power source DC Servomotor Driver DC Servomotor DC Servomotor Driver DC Servomotor In the typical Control System example shown above, a PC controls the movement of the workpiece bed across two horizontal axes using Limit Switches and Servomotors to monitor and control movement. 1-2 The Role of the PC The PC is the part of the Control System that directly controls the manufacturing process. According to the program stored in its memory, the PC accepts data from the input devices connected to it, and uses this data to monitor the controlled system. When the program calls for some action to take place, the PC sends data to the output devices connected to it to cause that action to take place. The PC may be used to control a simple, repetitive task, or it may be connected to other PCs, or to a host computer in order to integrate the control of a complex process. 3 Section 1 Introduction 1-2-1 Input Devices PCs can receive input from either automated or manual devices. The PC could receive data from the user via a pushbutton switch, keyboard, or similar device. Automated input could come from a variety of devices: microswitches, timers, encoders, photosensors, and so on. Some devices, like the Limit Switch shown below, turn ON or OFF when the equipment actually makes contact with them. Other devices, like the Photoelectric Switch and Proximity Switch shown below, use other means, such as light or inductance, in order to get information about the equipment being monitored. Photoelectric Switch Proximity Switch Limit Switch 1-2-2 Output Devices A PC can output to a myriad of devices for use in automated control. Almost anything that you can think of could be controlled (perhaps indirectly) by a PC. Some of the most common devices are motors, Solenoids, Servomotors, Stepping Motors, valves, switches, indicator lights, buzzers, and alarms. Some of these output devices, such as the motors, Solenoids, Servomotors, Stepping Motors, and valves, affect the controlled system directly. Others, such as the indicator lights, buzzers, and alarms, provide output to notify personnel. Solenoid Servomotor Stepping Motor 4 Section 1 Introduction 1-3 How Does a PC Work? PCs operate by monitoring input signals and providing output signals. When changes are detected in the signals, the PC reacts, through the user-programmed internal logic, to produce output signals. The PC continually cycles the program in its memory to achieve this control. Block Diagram of PC Power Supply Memory Signals from switches, sensors, etc. Input CPU Output Signals to Solenoids, motors, etc. Programming Device A program for your applications must be designed, and stored in the PC. This program is then executed as part of the cycle of internal operations of the PC. Scanning Cycle When a PC operates, that is, when it executes its program to control an external system, a series of operations are performed inside the PC. These internal operations can be broadly classified into the following four categories: 1. Common (or overseeing) processes, such as watchdog timer operation and testing the program memory. 2. Data input and output. 3. Instruction execution. 4. Peripheral device servicing. Cycle Time The total time required for a PC to perform all these internal operations is called the cycle time. The flowchart and diagram on page 7 illustrate these internal operations for a typical PC. Timing is one of the most important factors in designing a Control System. For accurate operations, it is necessary to have answers to such questions as these: • How long does it take for the PC to execute all the instructions in its memory? 5 Introduction Section 1 • How long does it take for the PC to produce a control output in response to a given input signal? The cycle time of the PC can be automatically calculated and monitored, but it is necessary to have an understanding of the timing relationships within the PC for effective System design and programming. 6 Section 1 Introduction PC Operation Flowchart Power application Clears data areas and resets System counters Initial processing on power application Checks I/O Unit connection Resets watchdog timer Checks hardware and program memory No Sets error flag and lights indicator Check OK?

Because the Memory Pack is not provided with the PC upon delivery, a Memory Pack must be selected and installed in the CPU. There are two Memory Packs available, either RAM or ROM, that can be used in the C500H PC. RAM Pack Data can be randomly written to and read from the RAM Pack, making it possible to enter your own program into the CPU. However, because this is not a fixed program, the memory of the RAM Pack is erased when power is not supplied to the CPU or when the RAM Pack is removed from the CPU. ! Caution Do not remove the battery in the CPU when the RAM Pack has been removed from the CPU. 64 128 CHIP 0 CHIP 1 CHIP 2 RAM Pack Two models of RAM Packs are available, which vary in memory capacity: 16K, and 24K words. Refer to Appendix C Standard Models for model numbers. Using a Programming Console, execute FUN (01) and a search operation to check the amount of memory available. 19 Section 2 Description of All Components ROM Pack Data contained in the ROM Pack is stored on EPROM chips and cannot be altered or erased during the CPU’s operation. Write the user’s program to the EPROM chips and mount the chips (3 max.) on the ROM chip. The entire pack is installed in the CPU. Once the data is written to the chip the data will not be lost when the power to the PC is OFF. 64 128 CHIP 0 CHIP 1 RAM Pack 20 CHIP 2 SECTION 3 Assembly 3-1 3-2 3-3 Mounting the Units . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

But actually even the simplest PCs are usually composed of several different devices. In fact a single PC can be physically spread throughout a building, but we still call it one PC. In this section, we will start with a Backplane and use all the Units discussed in Section 2 Description of All Components to build a PC. 3-1 Mounting the Units There is no single Unit that can be said to constitute a Rack PC. To build a Rack PC, we start with a Backplane. The Backplane for the C500 is shown below. C500 Backplane The Backplane is a simple device having two functions. The first is to provide physical support for the Units to be mounted to it. The second is to provide the connectors and electrical pathways necessary for connecting the Units mounted to it. The first device we will add to the Backplane is a Power Supply. The Power Supply fits into the rightmost position on the Backplane and provides electricity at the voltages required by the other Units of the PC. It can also be used to power devices other than the PC if necessary. Power Supply The core of the PC is the CPU. The CPU contains the program consisting of the series of steps necessary for the control task. The CPU fits into the position directly to the left of the Power Supply. CPU 22 Section 3 Assembly Unlike the CPU of the Package-type PC, the CPU of the Rack PC has no I/O points built in. So, in order to complete this kind of PC we need to mount one or more I/O Units to the Backplane. Mount the I/O Units to the Backplane by pressing the I/O Unit firmly into position, making sure the connectors are properly mated. Secure the Unit by tightening the mounting screws located on the top and bottom of the Unit. Mounting screws Provided at the top and bottom of the Unit Connector Make sure the connectors are properly mated. The figure below shows one I/O Unit mounted directly to the left slot of the CPU Rack. I/O Unit I/O Units are where the control connections are made from the PC to all the various input devices and output devices. As you can see from the figure, there is still some space available on the right side of the Backplane. This space is for any additional I/O Units that may be required. The figure above shows a total of eight I/O Units mounted to the Backplane. Backplanes are available in different lengths, and can hold a different number of I/O Units accordingly. Of course, not all I/O Units look exactly alike, but the ones in the figure show their typical appearance. This configuration of Backplane, Power Supply, CPU, and I/O Units is called a CPU Rack. This term refers to the Backplane and all the Units mounted to it. However, if we want to include more than eight I/O Units in our configuration we can add an addi- 23 Section 3 Assembly tional Backplane. First, though, we have to mount an I/O Control Unit to the leftmost slot of the CPU Rack. I/O Control Unit Now we can use a cable to connect the CPU Rack to another Backplane. This Backplane has a Power Supply and I/O Units mounted to it, but it has no CPU of its own. The additional Backplane must also have an I/O Interface Unit mounted to its leftmost position. This configuration of additional Backplane, Power Supply, I/O Units, and I/O Interface Unit is called an Expansion I/O Rack. CPU Rack Expansion I/O Rack I/O Interface Unit The CPU Rack and Expansion I/O Rack shown above are connected by a cable. Remember that this whole configuration is still referred to as one PC. It is possible to keep adding Expansion I/O Racks in this way until the maximum number of I/O points for the system is reached. Each Expansion I/O Rack needs an I/O Interface Unit. 24 Section 3 Assembly 3-2 Memory Packs The CPU has a removable Memory Pack that stores the user program. Two Memory Packs are available, in either RAM or ROM. You can write your own program into the RAM Pack or you can copy a program that has already been written to an EPROM chip and mount it in the ROM Pack. The EPROM Chip must be mounted to the PROM Writer in order for the program to be written to it. Then the EPROM Chip must be mounted to the ROM Pack. Mounting the EPROM Chip to the ROM Pack Depending on the amount of memory required for your application, use 1, 2, or 3 chips. Refer to Appendix B Specifications for specifications of the EPROM chips. Using the diagram and the table below as a reference, mount the EPROM chips to the correct IC sockets. 64 128 CHIP 0 CHIP 1 CHIP 2 RAM Pack The table below summarizes the programming capacity.

Caution Turn the power to the PC OFF. Do not attempt to install the Memory Pack in the CPU while the power to the PC is ON. Doing so may cause data to be lost, or may damage the CPU or Memory Pack. 25 Section 3 Assembly 2. Using a standard screwdriver, remove the Memory Pack compartment cover located on the front panel of the CPU. Push in the latch on the cover and slide the cover upward.

Insert the Memory Pack (component side facing left) into the Memory compartment. When the Unit is almost completely inserted into the CPU, there may be a slight resistance as the Memory Pack connector mates with the connector inside the CPU. Continue pushing on the Memory Pack until it is inserted completely into the CPU. Memory Unit guide Memory Pack (ROM or RAM Pack) 4. Reattach the memory compartment cover. How to Remove the Memory Pack Follow the steps below to remove the Memory Pack from the CPU. 26 1. Turn the power to the PC OFF. 2. Using a standard screwdriver, remove the Memory Pack compartment cover located on the front panel of the CPU. Push in the latch on the cover and slide the cover upward. 3. Pull the Memory Pack up and out. Section 3 Assembly Note 3-3 Memory in the RAM Pack is erased when the Memory Pack is removed from the CPU and when the CPU Unit is removed from the Rack. System Configurations The following figure shows an assembled C500 CPU Rack and one Expansion I/O Rack. When three Expansion I/O Racks are connected to a CPU Rack, a maximum of 512 I/O points are available. (Include the Remote I/O Units) CPU CPU Power Supply I/O Control Unit CPU Rack Connecting Cable Programming Console I/O Interface Unit Expansion I/O Power Supply Where I/O Units Can Be Mounted The table below summarizes the Units that can be used in the systems described in this manual. Special I/O Units Host Link Units The number of Special I/O Units that can be used depends upon the number of points available and the number of points the Special I/O Unit requires. Up to one Host Link Units can be mounted. Only one Rack-Mounting Host Link Unit can be mounted to the CPU Rack. A CPU-Mounting Host Link Unit can also be mounted directly to the CPU. Host Link Units cannot be mounted to Expansion I/O Racks. However, these Units cannot be mounted when the SYSMAC Net Link Unit is mounted. I/O Units Memory Packs Remote I/O Master Unit Standard I/O Units are available with 16, 32, or 64 points. Refer to Section 2 Description of All Components for details. RAM or ROM Packs are available. The ROM Pack requires a separately available EPROM chip. Up to four Remote I/O Master Units can be mounted to both the I/O Rack and the Expansion I/O Racks. When the Remote I/O Unit is mounted to a Rack, a Rack number must be set so that the CPU can identify the Remote I/O Unit. Mount the Remote I/O Slave Unit to the leftmost position (the I/O Interface Unit position) on the Slave Rack. For details, refer to the C500 Operation Manual. 27 Section 3 Assembly The following table summarizes specific Units that can and cannot be mounted in the CPU and Expansion Racks and the number that can be used in each PC. For more information about the Units, refer to the C500 Operation Manual. Unit CPU Rack Expansion Rack 16-, 32-, 64-point I/O YES YES Special I/O YES YES I/O Link YES YES PC Link YES (2 max.)

NO Remote I/O Master YES YES Remote I/O Slave NO YES *One Rack-mounting Host Link Unit can be mounted to the CPU Rack and one CPU-mounting Host Link Unit can be mounted directly to the CPU Unit. 28 Notes 1. The Position Control Unit and the PID Unit each require two I/O slots on the CPU Rack and the Expansion I/O Racks 2. The following Units can only be mounted to one of the three or five rightmost slots on the CPU Backplane, depending on which Backplane is used. PC Link Host Link SYSMAC Net Link 3. When two or more PCs are linked by the PC Link Unit, a maximum of 32 PC Link Units can be used (linking 31 PCs), in any number of subsystems. 4.

The terminals have screws with 3.5-mm diameter heads and self-raising pressure plates. Connect the lead wires to the terminals as shown. Always use solderless (crimp) terminals. Tighten the screws to a torque of 0.8 N S m. Use M3.5 self-rising screws for the terminal screws of the Power Supply Units. Always attach crimp terminals to the ends of the lead wires before attaching them to the terminals. Never attach loose or twisted wires. Tighten the screws on the terminal block to a torque of 0.8 N S m. Use crimp terminals for M3.5 screws of the dimensions shown below. 7 mm max. 7 mm max. 33 Section 4 System Connections Terminal Block The terminal block of an I/O Unit can be removed by loosening the mounting screws. You do not have to remove the lead wires from the terminal block in order to remove it from an I/O Unit. Note Putting I/O Lines and high-tension lines or power lines in the same duct or conduit may cause the I/O Lines to be affected by noise. This may cause a malfunction in the I/O Unit or may cause damage to the I/O Unit or I/O devices. Terminal block mounting screws Loosen the terminal block mounting screws to remove the terminal block from the I/O Unit. Make sure the mounting screws on the terminal block are tightened after wiring is complete, and the terminal block is remounted to the I/O Unit. Note When a Triac Output Unit is used to drive a low-current load, the load may not turn completely OFF due to a leakage current. To compensate for the leakage current, connect a bleeder resistor in parallel with the load. Wiring Examples The following are examples of how to connect I/O devices to I/O Units. During wiring, work slowly and carefully. If an input device is connected to an Output Unit, damage may result. Check all I/O devices to make sure they meet the specifications (refer to Appendix B Specifications). Be sure to allow for leakage current and load inductance.

For specific instructions on mounting Units and wiring for I/O and power, refer to Section 3-3 System Configurations and 4-2 I/O Connections. ! Caution 5-1 Static electricity can cause damage to PC components. Your body can carry an electrostatic charge, especially when the humidity is low. Before touching the PC be sure to first touch a grounded metallic object, such as a water pipe, in order to discharge any static build-up. Cooling There are two points to consider in order to ensure that the PC does not overheat. The first is the clearance between the Racks, and the second is installation of a cooling fan. Clearance Between Racks The Racks need to have sufficient room between each other to allow for I/O wiring, and additional room to ensure that the I/O wiring does not hamper cooling. However, the Racks must be mounted so that the length of the connecting cable does not exceed 2 m, and the total length of the Connecting Cables between all Racks does not exceed 12 m. For details about cable lengths, refer to Appendix C Standard Models. As a general rule, about 70 to 120 mm should be left between any two Racks. Cooling Fan A cooling fan is not always necessary, but may be needed in some installations. Try to avoid mounting the PC in a warm area, or over a source of heat. A cooling fan is needed if the ambient temperature may become higher than that specified (refer to Appendix B Specifications). If the PC is mounted in an enclosure install a cooling fan, as shown in the following diagram, to maintain the ambient temperature within specifications. Fan PC Louver 5-2 Mounting Requirements The PC consists of from one to nine Racks. Each Rack must be mounted vertically, that is with the printing on the front panels oriented as it would normally read. The Racks should be mounted one above the other with the CPU Rack uppermost. The PC may be directly mounted to any sturdy support meeting the environmental specifications (refer to Appendix B Specifications). 38 Section 5 Installation Environment The duct work shown in the following diagram is not used for mounting the Racks. Although optional, the duct work can be used to house the wires from the I/O Units that run along the sides of the Racks, keeping the wires from becoming entangled with other machines. The figures illustrate the correct way to mount the Racks. CPU Rack Expansion I/O Rack The following figure shows a side view of a mounted CPU and two Expansion I/O Racks. There should be a distance of 70 to 120 mm between the mounted Units. CPU Duct 70 to 120 mm I/O Duct 70 to 120 mm I/O Approx. 100 mm 39 Section 5 Installation Environment 5-3 Duct Work If power cables carrying more than 10 A 400 V, or 20 A 220 V must be run alongside the I/O wiring (that is, parallel to it), leave at least 300 mm between the power cables and the I/O wiring as shown below.

Avoid mounting the PC close to high-power equipment, and make sure the point of installation is at least 200 mm away from power cables as shown below. Power lines 200 mm min. PC 200 mm min. Whenever possible, use wiring conduit to hold the I/O wiring. Standard wiring conduit should be used, and it should be long enough to completely contain the I/O wiring and keep it separated from other cables. 41 SECTION 6 Power Considerations 43 Section 6 Power Considerations Introduction Use a commercially available 100 to 120 VAC, 200 to 240 VAC, or 24 VDC power source, according to the PC you are using (refer to Appendix B Specifications). Expansion I/O Racks, if used, must also be connected to the power source. If possible, use independent power sources for the PC, input devices, and output devices. All Racks of the PC may be connected to one power source. Grounding The Line Ground (LG) terminal is a noise-filtered neutral terminal that does not normally require grounding. If electrical noise is a problem, however, this terminal should be connected to the Ground (GR) terminal. To avoid electrical shock, attach a grounded (earth ground) AWG 14 wire (cross-sectional area: 2 mm2 min.) to the GR terminal. The resistance to ground must be less than 100 Ω. Do not use a wire longer than 20 m. Care must be taken, because ground resistance is affected by environmental conditions such as soil composition, water content, time of year, and the length of time since the wire was laid underground. PC operation may be adversely affected if the ground wire is shared with other equipment, or if the ground wire is attached to the metal structure of a building. When using an Expansion I/O Rack, the Rack must also be grounded to the GR terminal. The same ground can be used for all connections. Power Failure A sequential circuit is built into the PC to handle power interruptions. This circuit prevents malfunctions due to momentary power loss or voltage drops. A timing diagram for the operation of this circuit is shown below. OFF ON Power Supply Power failure detection signal Momentary power failure detection time CPU voltage (5 V) Power reset Approx. 1 s Run monitor outputs The PC ignores all momentary power failures if the interruption lasts no longer than 10 ms. If the interruption lasts between 10 and 25 ms, the interruption may or may not be detected. If the supply voltage drops below 85% of the rated voltage for longer that 25 ms (less for the DC Power Supply), the PC will stop operating and the external outputs will be automatically turned OFF. Operation is resumed automatically when the voltage is restored to more than 85% of the rated value. Wiring The following diagrams show the proper way to connect the power source to the PC. The terminals marked “NC” are not connected internally. 44 Section 6 Power Considerations AC Connections 3G2A5-PS221-E/223-E Screw (4 mm head with selfraising pressure plate) Breaker + 1:1 isolation transformer - Voltage selector Short: 100 to 120 VAC Open: 200 to 240 VAC Short-circuit these terminals with the shorting bracket supplied as an accessory to select 100 to 120 VAC supply voltage.

Caution Ground the Power Supplies separately from peripheral devices. 47 SECTION 7 Safety Considerations 49 Section 7 Safety Considerations Introduction There are certain safety requirements to be considered when installing the PC. Some of these, such as the emergency stop circuit (refer to Power Supply), are part of the initial wiring. The considerations described below should be kept in mind when operating the PC and when connecting I/O devices to the PC. Interlock Circuits When the PC controls an operation such as the clockwise and counterclockwise operation of a motor, provide an external interlock such as the one shown below to prevent both the forward and reverse outputs from turning ON at the same time. Interlock circuit 00501 MC2 MC1 Motor clockwise PC 00502 MC1 MC2 Motor counterclockwise This circuit prevents outputs MC1 and MC2 from both being ON at the same time. Even if the PC is programmed improperly or malfunctions, the motor is protected. Power Supply Output The 24 VDC output of the CPU and Expansion I/O Power Supply may be used to power other devices. The output current of these supplies is limited to 0.3 A. A separate Power Supply must be provided if the devices being powered require a higher current. Input Leakage Current When two-wire sensors, such as photoelectric sensors, proximity sensors or limit switches with LEDs are connected to the PC as input devices, the input bit may be turned ON erroneously by leakage current. In order to prevent this, connect a bleeder resistor across the input as shown below. Input power supply Bleeder resistor R PC Sensor If the leakage current is less than 1.3 mA, there should be no problem. If the leakage current is greater than 1.3 mA, determine the value and rating for the bleeder resistor using the following formulas. I = leakage current in mA 7.2 kΩ max. R= 2.4 x I – 3 2.3 W min. W= R 50 Section 7 Safety Considerations Output Leakage Current If there is a possibility of leakage current causing a transistor or triac to malfunction, connect a bleeder resistor across the output as shown below. OUT L R Load Power Supply PC Bleeder resistor COM Determine the value and rating for the bleeder resistor using the following formula. R EON I Where Eon = ON voltage of the load I = leakage current in mA R = bleeder resistance Output Surge Current When connecting a transistor or triac Output Unit to an output device having a high surge current (such as an incandescent lamp), care must be taken to avoid damage to the Output Unit. The transistor and triac Output Units are capable of withstanding a surge current of ten times the rated current. If the surge current for a particular device exceeds this amount, use the circuit shown below to protect the Output Unit. L OUT + R COM Another way of protecting the Output Unit lets the load draw a small current (about one third the rated current) while the output is OFF, significantly reducing the surge current. This circuit (shown below) not only reduces the surge current, but also reduces the voltage across the load at the same time. R OUT L + COM Transistor Output Residual Voltage When connecting TTL circuits to transistor Output Units, connect a pull-up resistor and a CMOS IC between the two. This is because of the residual voltage left on the transistor output after the output turns OFF. 51 Section 7 Safety Considerations Inductive Load Surge Suppressor When an inductive load is connected to an I/O Unit, connect a surge suppressor or diode in parallel with the load as shown in the following diagram. This is so that the back electromagnetic field generated by the load will be absorbed. Resistor: 50 W Capacitor: 0.47 µF Voltage: 200 V Diode: Must withstand voltages of more than three times the load voltage and an average current of 1 A IN L DC Input Diode COM OUT L Relay Output Unit Triac Output Unit Surge suppressor COM OUT L + Relay Output Unit Transistor Output Unit Diode COM Electrical Noise Take appropriate measures when any electrical device likely to produce noise is connected to the PC as a load. Devices generating noise of more than 1,200 V (such as electromagnetic relays and valves) require noise suppression. For noise sources running on AC power, connect a diode in parallel with the coil of each device. When mounting a CPU Rack and an Expansion I/O Rack together on a mounting plate, provide a solid ground to the mounting plate. The mounting plate must be plated with a highly conductive surface in order to ensure noise immunity. 52 Appendix A B C Inspection and Maintenance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Using digital switches or a specially wired keyboard, different combinations of points can access specific bits and words. Two examples of connections using digital switches or a keyboard are given. Connection Example 1 (Keyboard) The table below shows how the ID212 DC Input Unit can be wired using a specially wired keyboard. For example, if A on the keyboard is pressed, the combination of DATA0 and STB 9 turn ON bit 00, word n. Similarly, the combination of DATA 7 and STB 7 turn ON bit 15, word n+3. The value of word n depends on where the Unit is mounted on the Rack. For details, refer to the C500 Operation Manual.

If this cannot Appendix B Specifications be avoided, use shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m. Connection Example 2 (Digital Switches) This example shows how the ID212 DC Input Unit can be wired using digital switches. Just as the keys on the keyboard can access different combinations of words and bits, the digital switches can access different combinations of words and bits. For example, the combination of switch no. 1 and point 00 access word bit 00, word n. However, for the sake of simplicity the figure below shows the digital switches wired to control 32 bits instead of 64 bits as was shown in Example 1. Wire STB 4, STB 5, STB 6, and STB 7 to access an additional 32 bits. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 + 16 17 24 VDC 18 19 DATA 0 DATA 1 DATA 2 DATA 3 DATA 4 DATA 5 DATA 6 DATA 7 COM (+24) STB 0 STB 1 STB 2 STB 3 STB 4 STB 5 STB 6 STB 7 COM (0 V) +24 VDC NC D C B A COM Switch no. - - - - - - - - 8 7 6 5 4 3 2 1 + + + + + + + + 8 7 6 5 4 3 2 1 The table below shows the combinations made possible when the digital switches are wired as shown in the figure above.

Just like the ID211 DC Input Unit, different combinations of points can access bits and words to control different outputs. Using this type of Unit can simplify wiring when many bits must be controlled. Up to 64 bits can be accessed. Because the output data is positive logic, the terminal output goes high when the output data is logical 1. The strobe output is negative logic, so when a signal is output, the corresponding terminal goes low. Use positive logic output devices for the load of this Unit. The strobe output is cyclically and automatically output. 24 k Ω1W Ω1W 24 k 24 VDC 6 5 4 3 7 1 11 Display no. 68 8 7 6 5 4 3 2 1 0 DATA 0 1 DATA 1 2 DATA 2 3 DATA 3 4 DATA 4 5 DATA 5 6 DATA 6 7 DATA 7 8 CON (0 V) 9 STB 0 10 STB 1 11 STB 2 12 STB 3 13 STB 4 14 STB 5 15 STB 6 16 STB 7 17 CON (0 V) 18 24 VDC 19 NC Appendix B Specifications The table below shows the combinations made possible when the display is wired as shown in the figure on the preceding page.

Backplanes provide a series of connectors for these Units along with wiring to connect them to the CPU and Power Supply. Backplanes also provide connectors used to connect them to other Backplanes. In some Systems, different Backplanes are used for different Racks; in other Systems, Racks differ only by the Units mounted to them. back-up A copy of existing data which is valuable if data is accidentally erased. bit The smallest piece of information that can be represented on a computer. A bit has the value of either zero or one, corresponding to the electrical signals ON and OFF. A bit is one binary digit. central processing unit A device that is capable of storing a program and data, and executing the set of instructions contained in the program. In a PC System, the central processing unit executes the program, processes I/O signals, communicates with external devices, etc. communication cable Cable used to transfer data between components of a control system and conforming to the RS-232C or RS-422 standards. Control System All of the hardware and software components used to control other devices. A Control System includes the PC System, the PC programs, and all I/O devices that are used to control or obtain feedback from the controlled system. CPU An acronym for central processing unit. CPU Backplane A Backplane used to create a CPU Rack. CPU Rack Part of a Rack PC, the CPU Rack contains the CPU, a Power Supply, and other Units. data area An area in the PC’s memory that is designed to hold a specific type of data, e.g., the LR area is designed to hold common data in a PC Link System. data link Allows for the connection of up to 32 PCs in a Net Link System where each is contributing information to a common memory area. Data links may be established in the LR and/or DM memory areas. distributed control An automation concept in which control of each portion of an automated system is located near the devices actually being controlled, i.e., control is decentralized and “distributed” over the system. Distributed control is a concept basic to PC Systems. EEPROM [E(lectrically) E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM in which stored data can be erased and reprogrammed. This is accomplished using a special control lead connected to the EEPROM chip and can be done without having to remove the EEPROM chip from the device in which it is mounted. EPROM [E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM in which stored data can be erased, by ultraviolet light or other means, and reprogrammed. Expansion I/O Unit An I/O Unit for a Package-type PC that provides more I/O points to the PC. factory computer A general-purpose computer, usually quite similar to a business computer, that is used in automated factory control. High-speed Counter A Special I/O Unit. A High Speed Counter Unit counts independently of the PC’s cycle time. This allows counting of very short, fast signals. 103 Glossary host computer IBM PC/XT or AT, or compatibles A computer that is used to transfer data to or receive data from a PC in a Host Link system. The host computer is used for data management and overall system control. Host computers are generally small personal or business computers. A computer that has similar architecture to, and is logically compatible with an IBM PC/XT computer; and that can run software designed for that computer. I/O Expansion Backplane A Backplane used to create an Expansion I/O Rack. I/O Control Unit A Unit mounted to the CPU Rack in certain PCs to monitor and control I/O points on Expansion I/O Units. I/O devices The devices which are connected to the terminals on I/O Units, Special I/O Units, or Intelligent I/O Units. I/O devices may be part of the Control System if they function to help control other devices, or they may be part of the controlled system if they interact directly with it. I/O Expansion Rack Part of a Rack PC, an Expansion I/O Rack is connected to a CPU Rack to increase the number of slots available for mounting Units. I/O Interface Unit A Unit mounted to an Expansion I/O Rack in certain PCs to interface the Expansion I/O Rack to the CPU Rack. An I/O Interface Unit is needed when the first Expansion I/O Rack is connected to the CPU Rack via a Connecting Cable. Each Expansion I/O Rack needs an I/O Interface Unit. I/O point The place at which an input signal enters the PC System or an output signal leaves the PC System. In physical terms, an I/O point corresponds to terminals or connector pins on a Unit; in terms of programming, an I/O point corresponds to an I/O bit in the IR area. I/O Unit The most basic type of Unit mounted to a Backplane. I/O Units include Input Units and Output Units, each of which is available in a range of specifications. I/O Units do not include Special I/O Units, Link Units, etc. PC An acronym for Programmable Controller. PC Link Unit A Unit used to connect two or more PCs together so that they can exchange data through their LR areas. Position Control Unit A Special I/O Unit used to control the operation of positioning devices such as Servomotors. Power Supply A Unit that mounts to a Backplane in a Rack PC. It provides power at the voltage required by the other Units on the Rack. Programmable Controller A small, computer-like device that can control peripheral equipment, such as an electric door or quality control devices, based on programming and peripheral input devices. Any process that can be controlled using electrical signals can be controlled by a PC. PCs can be used independently or networked together into a system to control more complex operations. PROM [P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM into which the program or data may be written after manufacture, by a customer, but which is fixed from that time on. PROM Writer A PROM Writer is a device used to write data to ROM, PROM, and EPROM storage chips. Rack An assembly that forms a functional unit in a Rack PC System. A Rack consists of a Backplane and the Units mounted to it. These Units include the Power Supply, CPU, and I/O Units. Racks include CPU Racks, Expansion I/O Racks, and I/O Racks. The CPU Rack is the Rack with the CPU mounted to it. An Expansion I/O Rack is an additional Rack that holds extra I/O Units. An I/O Rack is used in the C2000H Duplex System, because there is no room for any I/O Units on the CPU Rack in this System. 104 Glossary Rack PC A PC that is composed of Units mounted to one or more Racks. This configuration is the most flexible, and most large PCs are Rack PCs. A Rack PC is the opposite of a Package-type PC, which has all of the basic I/O, storage, and control functions built into a single package. RAM [R(andom) A(ccess) M(emory)] RAM will not retain data when power is disconnected. Therefore data should not be stored in RAM. Remote I/O Unit A Unit that extends the distance an Expansion I/O Rack can be from the CPU. ROM [R(ead) O(nly) M(emory)] A type of digital storage that cannot be written to. A ROM chip is manufactured with its program or data already stored in it, and it can never be changed. However, the program or data can be read as many times as desired. Special I/O Unit A dedicated Unit that is designed for a specific purpose. Special I/O Units include Position Control Units, High-Speed Counters, Analog I/O Units, etc. system configuration The arrangement in which Units in a System are connected. This term refers to the conceptual arrangement and wiring together of all the devices needed to comprise the System. In OMRON terminology, system configuration is used to describe the arrangement and connection of the Units comprising a Control System that includes one or more PCs. Unit In OMRON PC terminology, the word Unit is capitalized to indicate any product sold for a PC System. though most of the names of these products end with the word Unit, not all do, e.g., a Remote Terminal is referred to in a collective sense as a Unit. Context generally makes any limitations of this word clear. 105 Index A AC Input, 35 Ambient Temperature of PC, 38 applications, precautions, ix ASCII, 32 B Backplane Expansion I/O, 14 I/O Expansion, 16 mounting Units to, 22 , 28 Bleeder Resistor, 50 Block, Terminal, 34 C Cable power, 40 twisted pair, 41 Clearance, Between PC Racks, 38 Conditions, Installation, 38 Conduit, 41 Connections I/O Units, 33 PC, 30 control components, 2 Cooling, PC, 38 CPU, 10 , 11 , 22 and Memory Packs, 19 , 25 and RAM Packs, 19 and ROM Packs, 20 Backplane, 10 connector, 11 core of PC, 22 Power Supply, 10 , 12 Rack, 10 CPU Rack, 23 connecting to another Backplane, 24 Current input leakage, 50 output leakage, 51 output surge, 51 Current Consumption, 30 Cycle Time, 5 D DC Input Units, 34 Duct, Wiring, 40 E Electrical Noise, 52 Electrostatic Charge, 38 Emergency Stop, 50 Environment, Installation, 38 EPROM Chip, mounting to ROM PAck, 25 Examples, wiring, 34 Expansion I/O Backplane, 14 Expansion I/O Power Supply, 27 Expansion I/O Rack, 10 , 14 , 24 Expansion I/O Racks, mounting Units to, 28 F Factory Computer, 2 Fan, cooling, 38 G Grounding, 44 Grounding During PC Installation, 40 H High Power Equipment, and PC installation, 41 Humidity, 38 I I/O Connections, 33 I/O Control Unit, 16 , 24 I/O Interface Unit, 16 , 24 I/O Points, 23 , 24 I/O Power Supply, 14 I/O Unit, 10 , 23 Link, power consumption, 32 mounting, 27 mounting to Backplane, 23 power consumption, 30 Remote, power consumption, 32 shapes, 16 Ashape, 16 Bshape, 17 Cshape, 17 Dshape, 18 Eshape, 18 Special, power consumption, 32 I/O Unit 3G2A5−PS213−E, 13 I/O Unit 3G2A5−PS223−E, 13 Inductive Load Surge Suppressor, 52 Input Devices, 4 Input Leakage Current, 50 Installation Environment, 38 Memory Pack to the CPU, 25 installation, precautions, ix 107 Index Interlock Circuits, 50 L Limit Switch, 4 M Memory Pack, installation, 25 Memory Packs, 19 , 25 Mounting EPROM Chip to ROM Pack, 25 I/O Units, 27 PC, 38 Mounting Units, 22 N Noise, electrical, 52 Noise, Preventing, 41 O operating environment, precautions, ix Output Devices, 4 Output Leakage Current, 51 Output Surge Current, 51 Output Units, 35 P PC ambient temperature, 38 and input devices, 4 and output devices, 4 clearance between racks, 38 components, 22 connections, 30 cooling the, 38 general, 2 how it operates, 5 I/O Unit mounting, 27 in a Control System, 2 installation environment, 38 its role, 3 mounting requirements, 38 Peripheral Device Connector, 11 Photoelectric Switch, 4 Position Control System, 3 Position Control Unit, 28 power consumption, 32 Power Cables, 40 Power Consideration, 44 Power Consumption, 30 Units, 30 , 31 , 32 Power Failure, 44 detection signal, 44 Power Reset, 44 108 Power Source, 44 Power Supplies, 30 Power Supply, 22 Backplane mounting, 22 CPU, 10 , 12 Expansion I/O, 14 I/O, 14 in a CPU Rack, 23 in block diagram, 5 output capacity, 30 Power Supply Output, 50 precautions applications, ix general, vii operating environment, ix safety, viii Preventing Noise, 41 process control computer, 2 Programmable Controller, flow chart, 7 Programmable Controller (also see PC), block diagram, 5 Programmable Controller (See also PC), 2 PROM, 25 Proximity Switch, 4 R Rack, PC, 39 RAM, 25 , 27 RAM Pack, 19 Remote I/O Unit Master, 27 Slave, 28 Reset, Power, 44 Residual Voltage, 51 Resistor, Bleeder, 50 ROM Pack, 20 S Safety Considerations, 50 safety precautions.
