WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, in order 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 doing so may result in serious accidents.

xii

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.

• The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.

• The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

• When the 24-VDC output (service power supply to the PC) is overloaded or short-circuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.

WARNING When transferring programs to other nodes, or when making changes to I/O

memory, confirm the safety of the destination node before transfer. Not doing so may result in injury.

Caution Execute online edit only after confirming that no adverse effects will be caused

by extending the cycle time. Otherwise, the input signals may not be readable.

Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the

torque specified in the operation manual. The loose screws may result in burning or malfunction.

5Application Precautions

4 Operating Environment Precautions

Caution Do not operate the control system in the following places:

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified in

the specifications.

• Locations subject to condensation as the result of severe changes in temperature.

• Locations subject to corrosive or flammable gases.

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

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

• Locations subject to shock or vibration.

Caution Take appropriate and sufficient countermeasures when installing systems in the

following locations:

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

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

Caution The operating environment of the PC System can have a large effect on the lon-

gevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PC System. Be sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life of the system.

5 Application Precautions

Observe the following precautions when using the PC System.

WARNING Always heed these precautions. Failure to abide by the following precautions

could lead to serious or possibly fatal injury.

xiii

• Always connect to a class-3 ground (to 100 Ω or less) when installing the Units. Not connecting to a class-3 ground may result in electric shock.

• Always turn off the power supply to the PC before attempting any of the following. Not turning off the power supply may result in malfunction or electric shock.

• Mounting or dismounting I/O Units, CPU Units, or any other Units.

• Assembling the Units.

• Connecting or wiring the cables.

• Connecting or disconnecting the connectors.

Caution Failure to abide by the following precautions could lead to faulty operation of the

PC or the system, or could damage the PC or PC Units. 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 Unit. If power supply for the I/O circuits comes ON before power supply for the Unit, 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 Unit 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 and frequency 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 Units in excess of the rated input voltage. Excess voltages may result in burning.

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

• Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning.

• Install the Unit properly as specified in the operation manual. Improper installation of the Unit may result in malfunction.

• 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.

• Be sure to attach the supplied labels when wiring in order to prevent wiring cuttings from entering in the Unit.

• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.

• Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning.

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

5Application Precautions

xiv

• 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.

• Check the user program for proper execution before actually running it on the Unit. 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.

• Changing the operating mode of the PC.

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• Resume operation only after transferring to the new CPU Unit the contents of

the DM and HR Areas required for resuming operation. Not doing so may result in an unexpected operation.

• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.

• Do not place objects on top of the cables. Doing so may break the cables.

• When replacing parts, be sure to confirm that the rating of a new part is correct.

Not doing so may result in malfunction or burning.

• Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in malfunction or damage.

• Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order to prevent any malfunction due to static electricity.

• When using a thermocouple-input type Temperature Sensor Unit, observe the following precautions:

• Do not remove the cold junction compensator attached at the time of delivery. If the cold junction compensator is removed the Unit will not be able to measure temperatures correctly.

• Each of the input circuits is calibrated with the cold junction compensator attached to the Unit. If the Unit is used with the cold junction compensator from other Units, the Unit will not be able to measure temperatures correctly.

• Do not touch the cold junction compensator. Doing so may result in incorrect temperature measurement.

5Application Precautions

Caution Always clear memory before beginning to program the CPM1A. Although

memory is cleared before the CPU Unit is shipped (except for bits with specific functions), AR 1314, which turns ON when the internal capacitor cannot back up memory, may have turned ON during shipment.

Caution If the CPM1A will be turned off for periods exceeding the data backup period of

the internal capacitor, design the system so that it will not be influenced if data in the DM, HR, and CNT areas is cleared when power is turned off.

Caution Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to

the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

• The user program and memory area data in the CPM1A are backed up either by an internal capacitor or in flash memory as shown in the following table.

Backup method Data

Internal capacitor Read/write DM area (DM 0000 to DM 0999, DM 1022, and

DM 1023) Error log area (DM 1000 to DM 1021) HR area (HR 00 to HR 19) Counter area (CNT 000 to CNT 127)

Flash memory User program

Read-only DM area (DM 6144 to DM 6599) PC Setup (DM 6600 to DM 6655)

Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is

turned off and all contents will be cleared the next time power is turned on. (The PC Setup setting in DM 6601 can be used to back up this data. Refer to details on the PC Setup later in this manual for details.)

2. The bits in the AR and SR areas have special functions and are set according to these functions when power is turned on.

• The capacitor backup time depends on the ambient temperature, as shown in the following graph. The backup time, however, assumes that the capacitor is fully charged, which requires that power be supplied to the CPU Unit continuously for at least 15 minutes.

5Application Precautions

Backup time (days)

25 40 80

Ambient temperature (C)

If the power remains off for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor will be cleared. AR 1314 will remain ON unless it is turned OFF using I/O monitor operations, using memory clear operations, or from the user program.

If desired, the PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON.

• The data stored in flash memory will not be lost even if power remains off for a period exceeding the data backup period, because the data stored in flash memory will be read to the CPU Unit when the CPM1A is turned on.

• If the power is turned off without changing the mode from PROGRAM mode to RUN or MONITOR mode after having made changes in the data that is backed up in flash memory, the changes will not be written to flash memory. If the power is then left off for more than 20 days (at 25C), the changes (i.e., the contents of the RAM) will be erased and the data values will become undefined.

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:

5Application Precautions

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).

6-3 Conformance to EC Directives

The CPM1A PCs (transistor output models) comply with EC Directives. Relay output models do not conform to the EC Directives. To ensure that the machine or device in which the CPM1A PC is used complies with EC directives, the PC must be installed as follows:

1, 2, 3... 1. The CPM1A 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. CPM1A 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.

4. The CPM1A with relay output does not conform to the EC Directives. For devices for use in the EC, use the CPM1, which meets the CE marking requirements. Further information is available at any of the OMRON offices or OMRON sales representatives listed on the inside back cover of this manual.

(Radiated emission: 10-m regulations)

6-4 CPM1A-MAD01 Conformance to EMC Directives

Immunity testing conditions when using the current I/O of the CPM1A-MAD01 are as follows.

• Total accuracy: +10%/-1%

• Insert the following core in each line as shown below.

1-1 CPM1A Features and Functions

1-1-1 CPM1A Features

One-piece Construction The CPM1A CPU Units feature a one-piece construction including 10, 20, 30, or

40 built-in I/O terminals. The following three model groups are available: relay output models, sink-type transistor output models, and source-type transistor output models.

CPM1A-10CDR-/10CDT-D/10CDT1-D (10 I/O terminals)

CPM1A-30CDR-/30CDT-D/30CDT1-D (30 I/O terminals)

CPM1A-20CDR-/20CDT-D/20CDT1-D (20 I/O terminals)

CPM1A-40CDR-/40CDT-D/40CDT1-D (40 I/O terminals)

Extra I/O Capacity Up to three Expansion I/O Units can be connected to a CPM1A-30CDR-/

30CDT-D/30CDT1-D or CPM1A-40CDR-/40CDT-D/40CDT1-D CPU Unit to add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points.

Input Filter Function The CPM1A is equipped with a filter function to prevent incorrect operation

caused by chatter or noise in the input signal. The user can select an input time constant of 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms.

Low-maintenance Design Flash memory provides memory backup without a battery. Input Interrupts The CPM1A-10CDR-/10CDT-D/10CDT1-D CPU Units can handle 2 interrupt

inputs; the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A-30CDR-/ 30CDT -D/30CDT1-D, and CPM1A-40CDR-/40CDT -D/40CDT1-D CPU Units can handle 4 interrupt inputs. In addition to normal input interrupts, the CPM1A has a counter mode that counts high-speed input signals and triggers interrupts at fixed count multiples.

Quick-response Inputs Quick-response inputs can detect input signals with a pulse width as short as

0.2 ms regardless of their timing during the PC cycle. Quick-response inputs and interrupt inputs use the same input terminals.

Interval Timer CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to

319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) o r repeat scheduled interrupts (scheduled interrupt mode).

High-speed Counter CPM1A PCs have a high-speed counter that can be used in incremental mode

or up/down mode. The high-speed counter can be combined with input interrupts to perform target value control or zone comparison control that isn’t affected by the PC’s cycle time.

Pulse Output Function The CPM1A transistor output models have an output function capable of output-

ting a pulse of 20 Hz to 2 kHz (single-phase output).

Analog Setting Function The CPM1A PCs have 2 analog volume controls that can be used to make

manual analog settings.

CPM1A Features and Functions Section 1-1

Analog I/O Units

Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs. Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 analog inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O Units.

The analog input range can be set to 0 to 1 0 VDC, 1 to 5 VDC, or 4 to 20 mA with a resolution of 1/256. (The open-circuit detection function can be used with the 1 to 5 VDC and 4 to 20 mA settings.)

The analog output range can be set to 0 to 10 VDC, –10 to 10 VDC, or 4 to 20 mA with a resolution of 1/256.

T emperature Sensor Units

A Temperature Sensor Unit can be connected to provide up to 6 inputs for temperature input from sensors, such as thermocouples or platinum resistance thermometers.

Host Link Communications The CPM1A PCs are compatible with the Host Link, which allows communica-

tions with personal computers. The CPM1A using the Host Link can also communicate with Programmable Terminal using host link commands.

An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is used for 1:N communications.

One-to-one PC Link A data link can be created with a data area in another CPM1A, CQM1, CPM1,

SRM1 or C200HS or C200HX/HE/HG PC. An RS-232C Adapter is used to make the 1:1 connection.

NT Link Communications High-speed operations can be achieved by providing a direct access by con-

necting the CPM1A to the OMRON Programmable Terminal through the NT Link Interface. An RS-232C Adapter is used for this connection.

CompoBus/S I/O Link Units

Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (internal) and 8 output bits (internal).

The CompoBus/S Network provides distributed CPU control based on a “PC + compact PC” configuration, which is an improvement on the earlier distributed I/O control based on a “PC + remote I/O” configuration. The distributed CPU control makes equipment modular, so designs can be standardized, special needs can be addressed, and modules can be replaced easily in the event of a breakdown.

Standard Peripheral Devices The CPM1A uses the same Programming Consoles and SYSMAC Support

Software (SSS) as the C200H/HS, C200HX/HE/HG, CPM1, SRM1, and CQM1 PCs.

Programming is Possible Using the PT

Programming operation is possible through the PT screen by using an OMRON PT that has a built-in Programming Console function.

CPM1A Features and Functions Section 1-1

Expansion Memory Unit

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

1-1-3 CPM1A Functions

Analog Setting Function CPM1A PCs have 2 variable-resistor adjustment knobs used to control analog

timer and counter settings manually. When one of the adjustments is turned, the content of the corresponding IR word is set automatically between 0 and 200 (BCD).

Turn the adjustment knob with a Phillips screwdriver.

0000 to 0200

Input Filter Function The input time constant for the CPM1A’s external inputs can be set to 1, 2, 4, 8,

16, 32, 64, or 128 ms. Increasing the input time constant can reduce the effects of chatter or noise in the input signal.

Input from an input device such as a limit switch

Input time constant

With the CPM1A, actual response time for each set input time constant for word 000 is different from that for word 001 or later.

1 ms 1 to 1.5 ms 0.1 to 0.3 ms 2 ms 2 to 2.5 ms 0.7 to 1.5 ms 4 ms 4 to 4.5 ms 1.5 to 2.5 ms 8 ms 8 to 8.5 ms 3 to 4.5 ms 16 ms 16 to 16.5 ms 6 to 9 ms 32 ms 32 to 32.5 ms 12 to 18 ms 64 ms 64 to 64.5 ms 24 to 35 ms 128 ms 128 to 128.5 ms 50 to 70 ms

The input response time of the CPM1A is obtained with the following:

2 ms max. (hardware performance) + input time constant (see above table) + cycle time

CPM1A Features and Functions Section 1-1

Input Interrupts The CPM1A-10CDR-/10CDT -D/10CDT1-D PCs have 2 interrupt input termi-

nals and the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A-30CDR-/ 30CDT-D/30CDT1-D, and CPM1A-40CDR-/40CDT-D/40CDT1-D PCs have 4 interrupt input terminals. There are two modes for input interrupts: input interrupt mode and counter mode.

1, 2, 3... 1. When a n interrupt occurs in Input Interrupt Mode, the main program is inter-

rupted and the interrupt program is executed immediately , regardless of the cycle time.

2. In Counter Mode, external input signals are counted at high speed (up to 1 kHz) and an interrupt is generated each time the count reaches the set value. When an interrupt occurs, the main program is interrupted and the interrupt program is executed. The set value can be set from 0 to 65,535.

The following diagram shows the program execution when an interrupt occurs.

Note When not using as interrupt input terminals, the input bits IR 00003 to IR 00006

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.

CPM1A Features and Functions Section 1-1

Quick-response Inputs The CPM1A-10CDR-/10CDT -D/10CDT1-D PCs have 2 quick-response input

terminals and the CPM1A-20CDR-/20CDT-D/20CDT1-D, CPM1A30CDR-/30CDT-D/30CDT1-D and CPM1A-40CDR-/40CDT-D/40CDT1-D PCs have 4 quick-response input terminals. (The same terminals are used for quick-response inputs and interrupt inputs.)

Quick-response inputs have an internal buffer, so input signals shorter than one cycle can be detected.

Pulse Output Function Since the CPM1A with transistor output has a pulse output function capable of

outputting a pulse of 20 Hz to 2kHz (single-phase output), a stepping motor can be controlled by the CPU Unit alone.

CPM1A Features and Functions Section 1-1

The pulse output can be set to either the continuous mode, under which the output can be stopped by an instruction, or the single mode, under which the output can be stopped by the preset pulse rate (1 to 16,777,215).

Revised Specifications

1-3 Revised Specifications

The following table shows the changes that have been made in product specifications beginning with lots produced in January 1998 (December 1997 for some models).

Item Previous specifications New specifications Relevant pages

Input indicator operation when an error occurs

Memory holding operation of built-in capacitor

Online editing and changing set values from the SSS

Communications parameters for the peripheral port

The input indicators will maintain the current status and will not change with the status of the input signal when a memory error, no END instruction error, or system error occurs.

If the power remains OFF for a period exceeding the data backup period, the capacitor will not be able to back up data and the status of the data backed up by the capacitor (Read/write DM area, Error log area, HR area, and Counter area) will become unstable.

If unsupported addresses are set in the program for operands or for set values for timers or counters from the SSS during online editing, the values will be accepted, but a memory error will occur in MONITOR or RUN mode.

Communications are not possible if unsupported settings are made for the peripheral port’s communications parameters.

The input indicators will change with the status of the input signal when a memory error, no END instruction error, or system error occurs.

If the power remains OFF for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor (Read/write DM area, Error log area, HR area, and Counter area) will be cleared. The PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON.

If unsupported addresses are set in the program for operands or for set values for timers or counters from the SSS during online editing, error messages will be displayed and the values will not be accepted.

Communications are possible using the following parameters if unsupported settings are made for the peripheral port’s communications parameters.

Ambient temperature (C)

If desired, the PC Setup setting in DM 6604 can be set to create a fatal error and thus stop the system when AR 1314 goes ON.

The data stored in flash memory will not be lost even if power remains off for a period exceeding the data backup period, because the data stored in flash memory will be read to the CPU Unit when the CPM1A is turned on.

If the power is turned off without changing the mode from PROGRAM mode to RUN or MONITOR mode after having made changes in the data that is backed up in flash memory, the changes will not be written to flash memory. If the power is then left off for more than 20 days (at 25C), the changes (i.e., the contents of the RAM) will be erased and the data values will become undefined.

Specifications Section 2-1

Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to the CPM1A after changing from a Programming Device any data that is backed up in flash memory. This data includes the user program, read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

Design Precautions Section 3-1

3-1 Design Precautions

Observe the following precautions when designing a system incorporating a CPM1A PC.

3-1-1 Power Supply Wiring

Separate the power supply wiring from the control system, CPM1A 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 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.

Construct an external interlock circuit if CPM1A outputs are used to perform reciprocal operations such as controlling the forward and reverse operation of a motor or if incorrect PC operation could cause accidents or mechanical damage. Also, construct an external limit circuit to prevent run-away movement in systems such as position control.

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 CPM1A outputs 01005 and 01006 are both ON (an incorrect PC operation).

3-1-3 Power Supply Voltage

Caution Use the power supply voltages indicated in Section 2 Unit Specifications and

Components. Failure to adhere to the specifications may result in fire. 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. Electric shock, product damage and malfunction may result.

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

• Assembling Units

• Connecting cables and wiring.

3-1-4 CPM1A Power Interruptions

Supply Voltage Drop

When the supply voltage falls below 85% of the rated value, the PC will stop and the outputs will go OFF.

Selecting an Installation Site

Section 3-2

Momentary Power Failure Detection

A momentary power failure lasting less than 10 ms with an AC power supply and 2 ms with a DC power supply is not detected and the CPU Unit continues to operate.

A momentary power failure lasting longer than 10 ms with an AC power supply and 2 ms with a DC power supply may or may not be detected in an uncertain area.

When a momentary power failure is detected, the CPU Unit stops operating and the output goes OFF.

Automatic Restart

When the supply voltage recovers to a value higher than 85% of the rated value, operations resumes automatically.

Duration of power interrupt (Below 85% of rated voltage)

Note The CPM1A may repeat stop/start operations if the supply voltage of less than

85% of the rated value gradually goes up or down. If this affects the equipment, etc., provide a protection circuit which shuts off the output if the supply voltage is not above the rated value.

Time Up to the Start of Operation

The time from when the power supply is turned on to when the operation starts varies depending on the operation conditions such as power supply voltage, configuration, ambient temperature, etc. The minimum time is approximately 300 ms.

3-2 Selecting an Installation Site

The CPM1A 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 CPM1A correctly, as outlined in this manual. Failure to do s o

may result in Unit malfunction.

Under Over

Normal operation Operation may stop.

10 ms (2 ms)

All outputs go OFF when

operations stop.

3-2-1 Installation Site Conditions

Note Do not install the CPM1A under any of the following conditions.

• Locations subject to direct sunlight.

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

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

100- to 240-VAC Power Supply

Wire a separate circuit for the CPM1A’s power supply circuit so that there isn’t a voltage drop from the inrush current that flows when other equipment is turned on.

When several CPM1A PCs are being used, it is recommended to wire the PCs on separate circuits to prevent a voltage drop from the inrush current or incorrect operation of the circuit breaker.

Use twisted power supply wires to prevent noise from the power supply lines. Adding a 1:1 isolating transformer reduces electrical noise even further.

Considering the possibility of voltage drops and the allowable current, be sure to use thick power lines.

Twist the wires. The cross-sectional area of each wire must be 1.25 mm2 min.

Leakage Current (24 VDC) A leakage current can cause false inputs when using 2-wire sensors (proximity

switches or photoelectric switches) or limit switches with LEDs. False inputs won’t occur if the leakage current is less than 1.0 mA (2.5 mA for

IN00000 to IN00002), but if the leakage current exceeds these values, insert a bleeder resistor in the circuit to reduce the input impedance, as shown in the following diagram.

Output Wiring Precautions 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 (0.5 to

1.0 A) in each output circuit.

Polarity of Power Supply for the Load

Double-check the polarity of the DC power supply for the load before wiring the transistor output. If the polarity of the power supply is reversely connected, the load will malfunction and internal components may be damaged.

Wiring and Connections

Section 3-4

Inductive Loads

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

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 switching a load with a high inrush current in the CPM1A relay output or transistor output model, such as an incandescent lamp, suppress the inrush current as shown below.

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

Countermeasure 2

Fuse Insertion

The CPM1A with transistor output may burn if the load is short-circuited, therefore, insert a protective fuse in series to the load.

Caution Always use crimp connectors for the CPM1A ’s power lines and I/O lines or else

use a solid wire (instead of a stranded wire). Do not connect bare stranded wires directly to terminals. Bare stranded wires connected directly to the terminal can cause a fire.

Use M3 terminal screws and tighten the screws securely (0.5 N  m).

It provides not only programming capabilities, but also advanced debugging, monitoring, and program/data management. The following tables provide only a brief introduction to the capabilities of the SSS. For further information and actual operating procedures, please refer to the SYSMAC Support Software Operation Manuals: Basics and C-series.

CPM1A programming can be performed with any version of the SSS. In addition, the SYSMAC-CPT can be used for programming the CPM1A. Refer

to the SYSMAC-CPT Support Software Quick Start Guide (W332) and User Manual (W333) for operation procedures. When programming the CPM1A using the SYSMAC-CPT, be sure to set the “PC model” on the Support Software to “CPM1 (CPM1A).” Operations for the WS02-CXPC1-E CX-Programmer are provided in the

WS02-CXPC1-E CX-Programmer User Manual (W361) and the CX-Server User Manual (W362).

4-1-1 SSS System Setup

Set the PC Model to “CQM1” and the PC Interface to “PERIPHERAL.” Follow the directions in the SSS operating manuals for other System Setup settings.

PC Model If the CPM1A PC doesn’t appear as an option in the SSS’s System Setup, set the

PC Model to “CQM1.” The CPM1A is compatible with the CQM1.

PC Interface Set the PC Interface to the Peripheral Device Port by selecting “PERIPHERAL”

from the submenu. After selecting the Peripheral Device Port, set the communications baud rate to 9,600 baud.

4-1-2 CPM1A Restrictions and Precautions

When programming the CPM1A, set the PC Model on the SSS to “CQM1.” Heed the following restrictions when programming the CPM1A.

Programming Check Since the data area of the CQM1 is larger than that of the CPM1A, some parts of

the area cannot be checked as the CPM1A PC. Pay careful attention to the usable data area when programming.

Note If a program that contains addresses not supported by the CPM1A are trans-

ferred to the CPM1A, a memory error will occur when operation is begun and AR 1308 will turn ON. Refer to t h e Programming Manual (W353) for dif ferences in memory areas.

Memory Usage Since the memory of the the CQM1 is larger than that of the CPM1A, the dis-

played available memory capacity is larger than the actual available memory capacity. Pay careful attention to the actual available memory capacity when programming.

Expansion Instructions When a program is transferred after changing the assignment of function codes

for the 18 expansion instructions, a message to “Turn on the DIP switch of the PC and execute again” is displayed. Change the assignment of the function codes for the expansion instructions to the default settings before programming.

The default settings for the CQM1 are as shown in the following table.

5. Enter the password. See 4-2-5 Entering the Password for details.

6. Clear (All Clear) the PC’s memory. See 4-3-2 Clearing Memory for details.

7. Read and clear all errors and messages. See 4-3-3 Reading/Clearing Error Messages for details.

8. Start programming.

4-2-5 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.

Using a Programming Console

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.
