PC or the system, or could damage the PC. Always heed these precautions.

• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.

• Construct a control circuit so that power supply for the I/O circuits does not come ON before power supply for the PC. If power supply for the I/O circuits comes ON before power supply for the PC, normal operation may be temporarily interrupted.

• If the operating mode is changed from RUN or MONITOR mode to PROGRAM mode, with the IOM Hold Bit ON, the output will hold the most recent status. In such a case, ensure that the external load does not exceed specifications. (If operation is stopped because of an operation error (including FALS instructions), the values in the internal memory of the CPU board will be saved, but the outputs will all turn OFF.)

• Always use the power supply voltage specified in the operation manuals. An incorrect voltage may result in malfunction or burning.

• Take appropriate measures to ensure that the specified power with the rated voltage is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction.

• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.

• Do not apply voltages to the input terminals in excess of the rated input voltage. Excess voltages may result in burning.

• Do not apply voltages or connect loads to the output terminals in excess of the maximum switching capacity. Excess voltage or loads may result in burning.

• Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.

• When wiring the CPM2B, take countermeasures to prevent wiring cuttings from coming into contact with the product, such as covering the whole product with a dustproof cover . I f wiring cuttings adhere to the PCB or circuit elements they may cause short-circuiting.

• Be sure to perform wiring in accordance with the relevant operation manual. Incorrect wiring may result in burning.

• Double-check all the wiring before turning ON the power supply. Incorrect wiring may result in burning.

• Be sure that the terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.

• Be sure that terminal blocks and connectors are connected in the specified direction with the correct polarity. Not doing so may result in malfunction.

• Check the user program for proper execution before actually running it on the PC. Not checking the program may result in an unexpected operation.

• Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.

5Application Precautions

xiv

6EC Directives

6 EC Directives

6-1 Applicable Directives

• EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note). Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN61131-2 EMI (Electromagnetic Interference): EN50081-2

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the required safety standards for the PC (EN61131-2).

(Radiated emission: 10-m regulations)

6-3 Conformance to EC Directives

The CPM2B PCs comply with EC Directives. To ensure that the machine or device in w h i c h t h e C P M 2 B P C i s u s e d c o mplies with EC directives, the PC must be installed as follows:

1, 2, 3... 1. The CPM2B PC must be installed within a control panel.

2. Reinforced insulation or double insulation must be used for the DC power supplies used for the communications and I/O power supplies.

3. CPM2B PCs complying with EC Directives also conform to the Common Emission Standard (EN50081-2). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.

6-4 Relay Output Noise Reduction Methods

The CPM2B PCs conform to the Common Emission Standards (EN50081-2) of the EMC Directives. However, the noise generated when the PC is switched ON or OFF using the relay output may not satisfy these standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PC.

Countermeasures taken to satisfy the standards vary depending on the devices on the load side, wiring, configuration of machines, etc. Following are examples of countermeasures for reducing the generated noise.

6EC Directives

Countermeasures

(Refer to EN50081-2 for more details.) Countermeasures are not required if the frequency of load switching for the

whole system with the PC included is less than 5 times per minute. Countermeasures are required if the frequency of load switching for the whole

system with the PC included is 5 times or more per minute.

If the supply voltage is 24 to 48 V, insert the surge protector in parallel with the load. If the supply voltage is 100 to 200 V, insert the surge protector between the contacts.

the load changes energy accumulated by the coil into a current, which then flows into the coil so that the current will be converted into Joule heat by the resistance of the inductive load.

This time lag, between the moment the circuit is opened and the moment the load is reset, caused by this method is longer than that caused by the CR method.

imposition of high voltage between the contacts by using the constant voltage characteristic of the varistor. There is time lag between the moment the circuit is opened and the moment the load is reset.

If the supply voltage is 24 to 48 V, insert the varistor in parallel with the load. If the supply voltage is 100 to 200 V, insert the varistor between the contacts.

6EC Directives

The capacitance of the capacitor must be 1 to 0.5 µF per contact current of 1 A and resistance of the resistor must be 0.5 to 1 Ω per contact voltage of 1 V. These values, however, vary with the load and the characteristics of the relay. Decide these values from experiments, and take into consideration that the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the current that flows into the load when the circuit is closed again.

The dielectric strength of the capacitor must be 200 to 300 V. If the circuit is an AC circuit, use a capacitor with no polarity.

The reversed dielectric strength value of the diode must be at least 10 times as large as the circuit voltage value. The forward current of the diode must be the same as or larger than the load current.

The reversed dielectric strength value of the diode may be two to three times larger than the supply voltage if the surge protector is applied to electronic circuits with low circuit voltages.

1-1 CPM2B Features and Functions

1-1-1 CPM2B Features

The CPM2B PCs are compact Board PCs that can be incorporated easily into control equipment. The PCs are equipped with a variety of advanced features including synchronized pulse control, interrupt inputs, high-speed counters, pulse outputs, and a clock function.

• The compact Board design is ideal for incorporation into control equipment.

• The CPU Board itself can handle a wide range of machine control applications,

so it is ideal for use as a built-in control unit in control equipment.

• The CPM2B is equipped with a full complement of communications functions to provide communications with personal computers, other OMRON PCs, and OMRON Programmable Terminals. These communications capabilities allow the user to design a low-cost distributed production system.

1-1SectionCPM2B Features and Functions

Relay Output Board

Basic Functions

CPU Board I/O

Peripheral Port Programming Devices are compatible with other models of OMRON PCs. This port can also be used for Host Link or no-protocol communications.

Transistor Output Board

The CPU Board has 32 I/O points and Expansion I/O Boards can be added to provide a total I/O capacity of up to 128 I/O points.

RS-232C Port This port can be used for a Host Link, no-protocol, 1:1 PC Link, or 1:1 NT Link communications.

The CPM2B CPU Board itself is equipped with 32 I/O points in I/O terminals or I/O connectors. There are 2 types of outputs available (relay outputs and sinking transistor outputs). The power supply is 24 V DC only.

Expansion I/O Boards

Up to 3 Expansion I/O Boards can be connected to the CPU Board to increase the PC’s I/O capacity to a maximum of 128 I/O points. There are 2 types of 32-point Expansion I/O Boards available: one with relay outputs and the other with sinking transistor outputs.

Share Programming Devices

The same Programming Devices, such as Programming Consoles and Support Software, can be used for the C200H, C200HS, C200HX/HG/HE, CQM1, CPM1, CPM1A, CPM2A, CPM2C, and SRM1 (-V2) PCs, so existing ladder program resources can be used effectively.

Built-in Motor Control Capability

Synchronized Pulse Control (Transistor Outputs Only)

Synchronized pulse control provides an easy way to synchronize the operation of a peripheral piece of equipment with the main equipment. The output pulse frequency can be controlled as some multiple of the input pulse frequency, al-

1-1SectionCPM2B Features and Functions

lowing the speed of a peripheral piece of equipment (such as a supply conveyor) to be synchronized with the speed of the main piece of equipment.

Encoder

CPM2B

Pulses are output as a fixed multiple of the input frequency.

Motor driver Motor

High-speed Counters and Interrupts

Easy Position Control with Pulse Outputs (Transistor Outputs Only)

The CPM2B has a total of five high-speed counter inputs. The one high-speed counter input has a response frequency of 20 kHz/5 kHz and the four interrupt inputs in counter mode have a response frequency of 2 kHz.

The high-speed counter can be used in any one of the four input modes: differential phase mode (5 kHz), pulse plus direction input mode (20 kHz), up/down pulse mode (20 kHz), or increment mode (20 kHz). Interrupts can be triggered when the count matches a set value or falls within a specified range.

The interrupt inputs in counter mode can be used for incrementing counters or decrementing counters (2 kHz) and trigger an interrupt (executing the interrupt program) when the count matches the target value.

CPM2B PCs with transistor outputs have two outputs that can produce 10 Hz to 10 kHz pulses (single-phase outputs).

When used as single-phase pulse outputs, there can be two outputs with a frequency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to 999.9 Hz with a variable duty ratio (0 to 100% duty ratio).

When used as pulse plus direction or up/down pulse outputs, there can be just one output with a frequency range of 10 Hz to 10 kHz.

High-speed Input Capabilities for Machine Control

High-speed Interrupt Input Function

There are four inputs used for interrupt inputs (shared with quick-response inputs and interrupt inputs in counter mode) with a minimum input signal width of 50 µs and response time of 0.3 ms. When an interrupt input goes ON, the main program is stopped and the interrupt program is executed.

Quick-response Input Function

Stabilizing Input Filter Function

Other Functions

Interval Timer Interrupts

Analog Settings

DIP Switch Inputs Calendar/Clock

Long-term Timer

There are four inputs used for quick-response inputs (shared with interrupt inputs and interrupt inputs in counter mode) that can reliably read input signals with a signal width as short as 50 µs.

The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms, 10 ms, 20 ms, 40 ms, or 80 ms. The ef fects of chattering and external noise can be reduced by increasing the input time constant.

The interval timer can be set between 0.5 and 319,968 ms and can be set to generate just one interrupt (one-shot mode) or periodic interrupts (scheduled interrupt mode).

There are two controls on the CPU Board that can be turned to change the analog settings (0 to 200 BCD) in IR 250 and IR 251. These controls can be used to easily change or fine-tune machine settings such as a conveyor belt’s pause time or feed rate.

A DIP switch is provided that controls the status of four input bits. The built-in clock (accuracy within 1 minute/month) can be read from the pro-

gram to show the current year, month, day, day of the week, and time. The clock can be set from a Programming Device (such as a Programming Console) or the time can be adjusted by rounding up or down to the nearest minute.

TIML(––) is a long-term timer that accommodates set values up to 99,990 seconds (27 hours, 46 minutes, 30 seconds). When combined with the SECONDS

1-1SectionCPM2B Features and Functions

TO HOURS conversion instruction (HMS(––)), the long-term timer provides an easy way to control equipment scheduling.

Expansion Memory Unit

The CPM1-EMU01-V1 Expansion Memory Unit is a program loader for smallsize or micro PCs. Using the CPM1-EMU01-V1, simple on-site transfer of user programs and data memory is possible with PCs.

Note 1. The NT-AL001-E must be supplied externally with 5 V DC. When an NT-

AL001-E is connected to a CPM2B PC, pin 6 of the CPM2B’s RS-232C port supplies +5 V DC and an external power supply is not necessary . When the NT-AL001-E is connected to a host computer, it is necessary to supply 5 V DC from an external power supply.

If an NT-AL001-E is connected to the CPM2B’s RS-232C port, only one Expansion I/O Board can be connected to the CPU Board because the NTAL001-E draws its 5-V DC power from the CPU Board.

Use an XW2Z-070T-1 (0.7 m) or XW2Z-200T-1 (2 m) cable to connect the NT-AL001-E to the CPM2B’s RS-232C port.

2. The 3G2A9-AL004-E requires an external AC power supply (110 V AC or 220 V AC).

3. The CPM1-CIF11 is supplied +5 V DC from the peripheral port so an external power supply is not necessary.

Output circuits

The program reads and writes data in this memory area during execution. Part of the I/O memory contains the bits that reflect the status of the PC’s inputs and outputs. Parts of the I/O memory are cleared when the power is turned ON and other parts are retained.

Note Refer to Section 4 Memory Areas for more details on I/O memory.

This is the program written by the user. The CPM2B executes the program cyclically. (Refer to 1-3-5 Cyclic Operation and Interrupts for details.)

The program can be divided broadly into two parts: the “main program” that is executed cyclically and the “interrupt programs” that are executed only when the corresponding interrupt is generated.

PC Setup

Communications Switches

The PC Setup contains various startup and operating parameters. The PC Setup parameters can be changed from a Programming Device only; they cannot be changed from the program.

Some parameters are accessed only when PC’s power supply is turned on and others are accessed regularly while the power is on. It will be necessary to turn the power off and then on again to enable a new setting if the parameter is accessed only when the power is turned on.

Note Refer to 4-5 PC Setup for more details.

The Communications Switches determine whether the peripheral port and RS-232C port operate with the standard communications settings or the communications settings in the PC Setup. Refer to 2-2 Board Components and their Functions for more details.

1-3-2 Operating Modes

CPM2B CPU Boards have 3 operating modes: PROGRAM, MONITOR, and RUN.

PROGRAM Mode

Caution The PC continues to refresh I/O bits even if the PC is in PROGRAM mode, so

The program cannot be executed in PROGRAM mode. This mode is used to perform the following operations in preparation for program execution

• Changing initial/operating parameters such as those in the PC Setup

• Writing, transferring, or checking the program

• Checking wiring by force-setting and force-resetting I/O bits

devices connected to output points on the CPU Board or Expansion I/O Boards may operate unexpectedly if the corresponding output bit is turned ON by changing the contents of I/O memory from a Programming Device.

1-3SectionStructure and Operation

MONITOR Mode

The program is executed in MONITOR mode and the following operations can be performed from a Programming Device. In general, MONITOR mode is used to debug the program, test operation, and make adjustments.

• Online editing

• Monitoring I/O memory during operation

• Force-setting/force-resetting I/O bits, changing set values, and changing pres-

ent values during operation

RUN Mode

The program is executed at normal speed in RUN mode. Operations such as online editing, force-setting/force-resetting I/O bits, and changing set values/ present values cannot be performed in RUN mode, but the status of I/O bits can be monitored.

1-3-3 Operating Mode at Startup

The operating mode of the CPM2B when the power is turned ON depends upon the PC Setup settings and the Programming Console’s mode switch setting if a Programming Console is connected.

PC Setup setting

Word Bits Setting

DM 6600 08 to 15

2. The default setting of bits 08 to 15 of DM 6600 is 00. With this default setting, the PC will automatically enter RUN mode if a Programming Console is not connected and SW201 is ON. Be sure that it is safe for the PC to operate before turning it ON under these conditions.

1-3-4 PC Operation at Startup

1-3SectionStructure and Operation

Time Required for Initialization

Power OFF Operation

The time required for startup initialization depends on several factors, such as the operating conditions (including power supply voltage, system configuration, and ambient temperature) and the program contents.

Minimum Power Supply Voltage

The PC will stop and all outputs will be turned OFF if the power supply voltage falls below 85% of the rated value.

Momentary Power Interruption

A power interruption will not be detected and CPU Board operation will continue if the power interruption lasts less than 2 ms for a DC power supply.

A power interruption may or may not be detected for power interruptions somewhat longer than 2 ms for a DC power supply.

When a power interruption is detected, the CPU Board will stop operating and all outputs will be turned OFF.

Automatic Reset

Operation will restart automatically when the power supply voltage is restored to more than 85% of the rated voltage.

Timing Chart of Power OFF Operation

The power interruption detection time is the time required for a power interruption to be detected after the power supply voltage drops below 85% of the rated value.

1, 2, 3... 1. Minimum power interruption detection time

Power interruptions that are shorter than 2 ms will not be detected.

time

CPU Board operation may continue if voltage is restored in this region.

Note If the power supply voltage fluctuates around 85% of the PC’s rated voltage, PC

operation may stop and restart repeatedly. When repeated stopping and starting will cause problems with the controlled system, set up a protective circuit such as a circuit that shuts off the power supply to sensitive equipment until the power supply voltage returns to the rated value.

1-3-5 Cyclic Operation and Interrupts

1-3SectionStructure and Operation

Basic CPU Operation

Initialization processing is performed when the power is turned on. If there are no initialization errors, the overseeing processes, program execution, I/O refreshing, and communications port servicing are performed repeatedly (cyclically).

S Perform RS-232C port communications

processing. (Can be changed in DM 6616.)

S Perform Peripheral port communications

processing. (Can be changed in DM 6617.)

The cycle time can be read from a Programming Device. AR 14 contains the maximum cycle time and AR 15 contains the present cycle

time in 4-digit BCD.

1-3SectionStructure and Operation

The cycle time will vary slightly depending on the processing being performed in each cycle, so the calculated cycle time will not always match the actual cycle time.

Program Execution in Cyclic Operation

The following diagram shows the cyclic operation of the CPM2B when the program is being executed normally.

Normally, the results of program execution are transferred to I/O memory just after program execution (during I/O refreshing), but IORF(97) can be used to refresh a specified range of I/O words during program execution. The specified range of I/O words will be refreshed when IORF(97) is executed.

The cycle time is the sum of the time required for program execution, I/O refreshing, and communications port servicing.

A minimum cycle time (1 to 9,999 ms) can be set in the PC Setup (DM 6619). When a minimum cycle time has been set, CPU operation is paused after program execution until the minimum cycle time is reached. CPU operation will not be paused if the actual cycle time is longer than the minimum cycle time set in DM 6619.

Note A fatal error will occur and PC operation will stop if a maximum cycle time has

been set in the PC Setup (DM 6618) and the actual cycle time exceeds that setting.

The default settings for RS-232C port servicing and Peripheral port servicing are 5% of the cycle time, but these settings can be changed (between 1% and 99%) in the PC Setup. The RS-232C port’s setting is in DM 6616 and the Peripheral port’s setting is in DM 6617.

1-3SectionStructure and Operation

Interrupt Program Execution

When an interrupt is generated during execution of the main program, main program execution is interrupted immediately and the interrupt program is executed. The following diagram shows the cyclic operation of the CPM2B when an interrupt program is executed.

Normally, the results of interrupt program execution are transferred to I/O memory just after program execution (during I/O refreshing), but IORF(97) can be used to refresh a specified range of I/O words during execution of the interrupt program. The specified range of I/O words will be refreshed when IORF(97) is executed.

The normal cycle time is extended by the time required for execution of the interrupt program.

Refer to Section 7 PC Operations and Processing Time in the CPM1/CPM1A/

CPM2A/CPM2C/SRM1(-V2) Programmable Controllers Programming Manual

(W353) for more details and precautions on the cycle time.

Caution Although IORF(97) can be used in interrupt subroutines, you must be careful of

the interval between IORF(97) executions. If IORF(97) is executed too frequently, a fatal system error may occur (FALS 9F), stopping operation. The interval between executions of IORF(97) should be at least 1.3 ms + total execution time of the interrupt subroutine.

Immediate Refreshing

IORF(97) can be executed in the program to refresh a specified range of I/O words. The specified I/O words will be refreshed when IORF(97) is executed.

IORF(97) can be used to refresh I/O from the main program or the interrupt program.

When IORF(97) is used, the cycle time is extended by the time required to refresh the specified I/O words.

Note 1. The DM area, HR area, AR area, and counter values are backed up by the

CPU Board’s built-in battery or capacitor. If the battery or capacitor is discharged, the contents of these areas will be lost and the data values will revert to the defaults.

2. The contents of the program area, read-only DM area (DM 6144 to DM 6599), and PC Setup (DM 6600 to DM 6655) are stored in flash memory. The contents of these areas will be read from flash memory the next time the power is turned ON, even if the backup battery or capacitor is discharged.

When data has been changed in any of these areas, write the new values to flash memory by switching the CPM2B to MONITOR or RUN mode, or by turning the power OFF and then ON again.

5. Input Indicators The input indicators are lit when the corresponding input terminal is ON. The

status of an input indicator will reflect the status of the input even when that input is being used for a high-speed counter.

Note a) When interrupt inputs are used in interrupt input mode, the indica-

tor may not light even when the interrupt condition is met if the input is not ON long enough. When a high-speed counter is being used, the indicator may not light depending on the speed of the pulses.

b) Input indicators will reflect the status of the corresponding inputs

even when the PC is stopped, but the corresponding input bits will not be refreshed.

6. Output Indicators The output indicators are lit when the corresponding output terminal is ON.

The indicators are lit during I/O refreshing. When an output is being used as a pulse output, the corresponding will remain lit while pulses are being output.

3-1 Design Precautions

Observe the following precautions when designing a system incorporating a CPM2B PC.

3-1-1 Power Supply Wiring

Separate the power supply wiring from the power system, control system, CPM2B system, and DC I/O system wiring. Separate the control circuits that supply power to the main Unit from the main circuits using dedicated circuit protectors and fuses.

3-1-2 Power Supply Voltage

Caution Use the power supply voltages indicated in Section 2-1 Specification. Failure to

adhere to the specifications may result in fire. If the power supply voltage falls below 85% of the rated voltage, the CPM2B will stop and all outputs will be turned OFF. If low voltage affects the equipment, etc., provide a protection circuit which shuts off the output until the supply voltage returns to the rated value. In places where power supply conditions are poor, take steps to ensure that power is supplied at the rated voltage. Be sure to adhere to safety precautions, such as providing breakers to prevent short circuits in external wiring. When conducting any of the following operations, turn OFF the power to the PC. Electrocution, product damage and malfunction may result.

3-2SectionSelecting an Installation Site

• Connecting or disconnecting Expansion I/O Boards and CPU Boards.

• Assembling equipment.

• Connecting cables and wiring.

3-1-3 Interlock and Limit Circuits

WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety

measures must be provided in external control circuits (i.e., not in the Programmable Controller) to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC operation. Not providing proper safety measures may result in serious accidents.

The following diagram shows an example of an interlock circuit.

In the interlock circuit above, MC1 and MC2 can’t be ON at the same time even if CPM2B outputs 01005 and 01006 are both ON (an incorrect PC operation).

3-2 Selecting an Installation Site

The CPM2B is resistant to harsh conditions and highly reliable, but installing the PC in a favorable site will maximize its reliability and operating lifetime.

Caution Be sure to install the CPM2B correctly, as outlined in this manual. Failure to do s o

may result in Board malfunction.

3-2-1 Installation Site Conditions

Note Do not install the CPM2B under any of the following conditions.

• Locations subject to direct sunlight.

• Locations subject to an ambient temperature below 0°C or over 55°C.

• Locations subject to an ambient humidity below 10% or over 90%.

• Locations subject to condensation as the result of severe changes in tempera-

ture.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to shock or vibration.

• Locations subject to exposure to water, oil, or chemicals.

Be sure that the conditions at the installation site conform to the CPM2B’s general specifications. Refer to 2-1-1 General Specifications for details.

Note Provide proper shielding when installing in the following locations:

• Locations subject to static electricity or other sources of noise.

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radiation.

• Locations near to power supply lines.

3-2SectionSelecting an Installation Site

3-2-2 Panel/Cabinet Installation

Consider PC operation, maintenance, and surrounding conditions when installing the CPM2B in a panel or cabinet.

Overheating

Electrical Noise

The ambient operating temperature range for the CPM2B is 0_C to 55_C. Be sure that there is adequate ventilation for cooling.

• Allow enough space for air circulation.

• Do not install the CPM2B above equipment that generates a large amount of

heat, such as heaters, transformers, or large resistors.

• Install a cooling fan or system when the ambient temperature exceeds 55_C.

Power lines and high-voltage equipment can cause electrical noise in the PC.

• Do not install the CPM2B in a panel or cabinet with high-voltage equipment.

• Allow at least 200 mm between the CPM2B and nearby power lines.

Observe the following precautions to protect the PC’s internal components.

Output Short Protection

The output or internal circuitry might be damaged when the load connected to an output is short-circuited, so it is recommended to install a protective fuse in each output circuit.

Inductive Loads

When connecting an inductive load to an input, connect a surge protector or diode in parallel with the load.

The surge protector’s components should have the following ratings:

3-5SectionWiring and Connections

The diode should satisfy the following requirements:

Peak reverse-breakdown voltage must be at least 3 times the load voltage. Average rectified current must be 1 A.

Inrush Current Considerations

When a relay or transistor output is used to switch a load with a high inrush current such as an incandescent lamp, suppress the inrush current as shown below.

Countermeasure 1

Providing a dark current of approx. one-third of the rated value through an incandescent lamp

Countermeasure 2

Providing a limiting resistor

Fuse Insertion

The CPM2B with transistor output may burn if the load is short-circuited, therefore, insert a protective fuse in series with the load.

This section describes the structure of the PC memory areas and explains how to use them.

4-1-1 Functions

IR Area

The functions of the IR area are explained below. IR area bits in the input and output areas are allocated to terminals on the CPU

Board and Expansion I/O Boards. They reflect the ON/OFF status of input and output signals. Input bits begin at IR 00000, and output bits begin at IR 01000.

4-2SectionI/O Allocation

IR words that are not allocated to inputs or outputs can be used as work words.

Work Bits

SR Area

TR Area

HR Area

AR Area

LR Area

The work bits can be used freely within the program. They can only be used within the program, however , and not for direct external I/O.

These bits mainly serve as flags for CPM2B operation or contain present and set values for various functions. SR 253 to SR 255 are read-only. Refer to 4-3 SR Area for details on the various bit functions.

When a complex ladder diagram cannot be programmed in mnemonic code just as it is, these bits are used to temporarily store ON/OFF execution conditions at program branches. They are used only for mnemonic code. When programming directly with ladder diagrams using the Support Software, TR bits are automatically processed for you.

The same TR bits cannot be used more than once within the same instruction block, but can be used again in different instruction blocks. The ON/OFF status of TR bits cannot be monitored from a Programming Device.

These bits retain their ON/OFF status even after the PC power supply has been turned off or when operation begins or stops. They are used in the same way as work bits.

These bits mainly serve as flags related to PC operation. These bits retain their status even after the PC power supply has been turned off or when operation begins or stops. Refer to 4-4 AR Area for details on the various bit functions.

When the CPM2B is linked 1:1 with another CPM2B or a CPM1/CPM1A/ CPM2A/CPM2C/SRM1(-V2), a CQM1, a C200HS or a C200HX/HG/HE PC, these bits are used to share data.

LR words can be used as work words when they are not used for a 1:1 PC Link.

Timer/Counter Area

DM Area

4-2 I/O Allocation

This area is used to manage timers and counters created with TIM, TIMH(15), TMHH(––), TIML(––), CNT, and CNTR(12). The same numbers are used for both timers and counters and each number can be used only once in the user program. Do not use the same TC number twice even for different instructions.

Use TC numbers 000 to 003 for TIMH(15) and TC numbers 004 to 007 for TMHH(––). When these timer numbers are used, timing is performed as an interrupt process and the cycle time is not affected.

TC numbers are used to create timers and counters, as well as to access Completion Flags and present values (PVs). If a TC number is designated for word data, it will access the present value (PV); if it is used for bit data, it will access the Completion Flag for the timer/counter.

DM area data is accessed in word units only. The contents of the DM area are retained even after the PC power supply has been turned off or when operation begins or stops.

DM words DM 0000 to DM 1999 and DM 2022 to DM 2047 can be used freely in the program; other DM words are allocated specific functions.

DM 2000 to DM 2021 contain the error log information. Refer to Section 4-6 Error Log for details on the error log.

DM 6600 to DM 6655 contain the PC Setup. Refer to 4-5 PC Setup for details.

IR bits are allocated to actual input terminals and output terminals on the CPU Board and Expansion I/O Boards. IR words that are not allocated to inputs or outputs can be used as work words.

Note 1. The unused bits in IR 000 and IR 001 cannot be used as work bits.

2. IR 00108 to IR 00111 are used as an input DIP switch.

Up to 3 Expansion I/O Boards can be connected. Input bits are allocated to Expansion I/O Boards starting from word (m+1), where

“m” is the last input word allocated to the CPU Board or to the previous Expansion I/O Board if one is already connected.

Output bits are allocated to Expansion I/O Boards starting from word (n+1), where “n” is the last output word allocated to the CPU Board or to the previous Expansion I/O Board if one is already connected.

DM read/write words (DM 0000 to DM 1999 and DM 2022 to DM 2047), Error Log (DM 2000 to DM 2021), HR area, counter area, SR 25511, SR 25512 (if DM 6601 is set to hold I/O memory at startup), AR 23, operating mode (if DM 6600 is set to use the previous operating mode).

If the above words cannot be retained, all data will be cleared except that AR 2114 will be turned ON in CPU Boards equipped with a clock. The CPU Board will start in PROGRAM mode if DM 6600 is set to use the previous operating mode. (If DM 6604 is set to generate an error, the PC will start in PROGRAM mode regardless.)

Turn this bit ON to stop the clock. The time/date can be overwritten while this bit is ON. 15 Clock Set Bit

To change the time/date, turn ON AR 2114, write the new time/date (being sure to leave AR

2114 ON), and then turn this bit ON to enable a new time/date setting. The clock will restart and

both AR 2114 and AR 2115 will be turned OFF automatically.

This is the count of the number of times that the power has been turned off.

To clear the count, write “0000” from a Programming Device.

Note 1. The same data can be read immediately with PRV(62).

2. The time and date can be set while AR 2114 is ON. The new setting becomes effective when AR 2115 is turned ON. (AR 2114 and AR 2115 are turned OFF automatically when the new setting goes into effect.)

3. The units for the maximum and current cycle times are determined by the setting in bits 08 to 15 of DM 6618. A setting of 00 specifies 0.1-ms units, 01 specifies 0.1-ms units, 02 specifies 1-ms units, and 03 specifies 10-ms units.

4-5SectionPC Setup

4-5 PC Setup

The PC Setup comprises various operating parameters that control PC operation. In order to make the maximum use of PC functionality when using interrupt processing and communications functions, the PC Setup may be customized according to operating conditions.

After the PC Setup has been changed, be sure to switch the CPM2B to MONITOR or RUN mode or turn the power OFF and then ON again.

4-5-1 Changing the PC Setup

The PC Setup settings in DM 6600 to DM 6655 can be changed from a Programming Device. The CPM2B must be in PROGRAM mode in order to change the settings in DM 6600 to DM 6644. The settings in DM 6645 to DM 6655 can be changed in MONITOR or PROGRAM mode, but CPM2B’s cycle time will be long if the settings are changed in MONITOR mode.

All of the PC Setup settings are set to their defaults when the CPM2B is shipped. The default values for the PC Setup are 0000 for all words (except for the low battery error enable in DM 6655 bits 12 to 15).

Effectiveness of Changes

PC Setup settings are accessed at various times depending on the setting, as described below.

Words Timing

DM 6600 to DM 6614 Accessed only when PC’s power supply is turned ON. DM 6615 to DM 6644 Accessed only when program execution begins. DM 6645 to DM 6655 Accessed regularly when the power is ON.

Since changes in the PC Setup become effective only at the times given above, the PC will have to be restarted to make changes in DM 6600 to DM 6614 effec-

4-5SectionPC Setup

tive, and program execution will have to be restarted to make changes in DM 6615 to DM 6644 effective.

Errors in the PC Setup

If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B) will be generated, the corresponding error flag (AR 1300 to AR 1302) will be turned ON, and the default setting will be used instead of the incorrect setting.

(3 words used.)

Error log record 7 (3 words used.)

The error log function registers the error code of any fatal or non-fatal error that occurs in the PC. The date and time at which the error occurred are registered along with the error code. The error code is also stored in AR 253.

The error log is stored in DM 2000 through DM 2021. Up to 7 error records can be stored.

Indicates the number of records stored in the log (0 to 7). A 0 indicates no records.

Each error log record is configured as follows:

15 8 7 0

Leading word Leading word + 1 Leading word + 2

Error classification Error code Min Sec Day Hour

Error classification: 00: Non-fatal

80: Fatal

Each stored in 2 digits BCD.

Note 1. An error record with an error code of 00 will be stored in the error log for pow-

er interruptions. Refer to 7-3 Self-diagnostic Functions for tables listing error codes.

2. In CPU Boards without a clock, the time that the error occurred will be set to all zeroes.

Error Log Storage Methods

The error log storage method is set in the PC Setup (bits 00 to 03 of DM 6655). Set any of the following methods.

1, 2, 3... 1. DM 6655 bits 00 to 03 set to 0:

Stores the most recent 7 error log records and discard older records. This is achieved by shifting the records as shown below so that the oldest record (record 0) is lost whenever a new record is generated.

Error log record 1 Error log record 2

Error log record 6 Error log record 7

2. DM 6655 bits 00 to 03 set to 1: Stores only the first 7 error log records, and ignores any subsequent errors beyond those 7.

3. DM 6655 bits 00 to 03 set to any value other than 0 or 1: Disables the log so that no records are stored.

The default setting is the first method. Refer to the preceding page for details on the error log settings in DM 6655.

Clearing the Error Log

To clear the entire error log, turn ON SR 25214 from a Programming Device. (After the error log has been cleared, SR 25214 will turn OFF again automatically.)

5-3 Expansion Instructions

A set of expansion instructions is provided to aid in special programming needs. Function codes can be assigned to up to 18 of the expansion instructions to enable using them in programs. This allows the user to pick the instructions needed by each program to more effectively use the function codes required to input instructions.

The mnemonics of expansion instructions are followed by “(––)” as the function code to indicate that they must be assigned function codes by the user in the instructions table before they can be used in programming (unless they are used under their default settings).

Refer to the 6-2-5 Assigning Expansion Instruction Function Codes for a description of the Programming Console operations used to change expansion instruction allocations.

Refer to the SYSMAC Support Software Operation Manuals: C-series PCs (W248), the SYSMAC-CPT Support Software User Manual (W333), or the WS02-CXPC1-E CX-Programmer User Manual (W361) for a description of the corresponding Support Software operations.

The CPM2B program isn’t executed in PROGRAM mode. Use PROGRAM mode to create and edit the program, clear memory, or check the program for errors, or check output wiring.

MONITOR Mode

The CPM2B program is executed in MONITOR mode and I/O is processed just as it is in RUN mode. Use MONITOR mode to test system operations, such as monitoring CPM2B operating status, force-setting and resetting I/O bits, changing the SV/PV of timers and counters, changing word data, and online editing.

RUN Mode

This is the CPM2B’s normal operating mode. The CPM2B’s operating status can be monitored from a Programming Device, but bits can’t be force-set/force-reset and the SV/PV of timers and counters can’t be changed.

6-1-4 Preparation for Operation

This section describes the procedures required to begin Programming Console operation when using the Programming Console for the first time.

Caution Always confirm that the Programming Console is in PROGRAM mode when

turning ON the PC with a Programming Console connected unless another mode is desired for a specific purpose. If the Programming Console is in RUN mode when PC power is turned ON, any program in Program Memory will be executed, possibly causing a PC-controlled system to begin operation.

The following sequence of operations must be performed before beginning initial program input.

1, 2, 3... 1. Be sure that the PC is OFF.

2. Connect the Programming Console to the CPU Board’s peripheral port. See 6-1-3 Connecting the Programming Console for details. (The CPU Board’s Communications Switch setting has no effect on communications with the Programming Console.)

3. Set the mode switch to PROGRAM mode.

4. Turn ON the PC.

5. Enter the password. See 6-1-5 Entering the Password for details.

6. Clear (All Clear) the PC’s memory. See 6-2-2 Clearing Memory for details.

7. Read and clear all errors and messages. See 6-2-3 Reading/Clearing Error Messages for details.

About 70 mm is required.

8. Start programming.

6-1-5 Entering the Password

To gain access to the PC’s programming functions, you must first enter the pass- word. The password prevents unauthorized access to the program.

The PC prompts you for a password when PC power is turned on or, if PC power is already on, after the Programming Console has been connected to the PC. To gain access to the system when the “Password!” message appears, press CLR and then MONTR. Then press CLR to clear the display.

If the Programming Console is connected to the PC when PC power is already on, the first display below will indicate the mode the PC was in before the Programming Console was connected. Ensure that the PC is in PROGRAM mode before you enter the password. When the password is entered, the PC will shift to the mode set on the mode switch, causing PC operation to begin if the mode is set to RUN or MONITOR. The mode can be changed to RUN or MONITOR with the mode switch after entering the password.

Caution The PC Setup (DM 6600 through DM 6655) will be cleared when this operation is

performed.

Partial Clear It is possible to retain the data in specified areas or part of the Program Memory.

To retain the data in the HR, TC, or DM Areas, press the appropriate key after pressing SET, NOT, and RESET. Any data area that still appears on the display will be cleared when the MONTR Key is pressed.

The HR Key is used to specify both the AR and HR Areas, the CNT Key is used to specify the entire timer/counter area, and the DM Key is used to specify the DM Area.

It is also possible to retain a portion of the Program Memory from the first memory address to a specified address. After designating the data areas to be retained, specify the first Program Memory address to be cleared. For example, input 030 to leave addresses 000 to 029 untouched, but to clear addresses from 030 to the end of Program Memory.

As an example, follow the procedure below to retain the timer/counter area and Program Memory addresses 000 through 122:

6-2-3 Reading/Clearing Error Messages

This operation is used to display and clear error messages. It is possible to display and clear non-fatal errors and MESSAGE instruction messages in any mode, but fatal errors can be cleared in PROGRAM mode only.

RUN MONITOR PROGRAM

OK OK OK

Before inputting a new program, any error messages recorded in memory should be cleared. It is assumed here that the causes of any of the errors for which error messages appear have already been taken care of. If the buzzer sounds when an attempt is made to clear an error message, eliminate the cause of the error, and then clear the error message. (Refer to Section 7 Test Runs and Error Processing for troubleshooting information.)

Key Sequence Follow the procedure below to display and clear messages.

1, 2, 3... 1. Press the CLR Key to bring up the initial display.

2. Press the FUN and then the MONTR Key to begin the operation. If there are no messages, the following display will appear:

This operation is used to display or change the expansion instructions assigned to expansion instruction function codes. The assignments can be displayed in any mode, but can be changed in PROGRAM mode only.

Operation RUN MONITOR PROGRAM

Read assignment OK OK OK Change assignment No No OK

Assign expansion instruction function codes before inputting the program. The CPM2B will not operate properly if expansion instructions aren’t assigned correctly. An expansion instruction can be assigned to one function code only.

The PC Setup must be set for user-defined expansion instruction assignments. Set bits 8 to 11 of DM 6602 to 1 and turn the PC’s power off and then on again to enable the new setting.

There are tables in Section 5 Instruction Set showing the default function code assignments in the CPM2B.
