3Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so

may result in electric shock.

! WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock.

! WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.

! 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.

•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.

4Operating 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.

•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-circuit- ing 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.

•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.

!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.

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.

Backup time (days)

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:

EMS (Electromagnetic Susceptibility): EN61131-2

EMI (Electromagnetic Interference): EN50081-2

(Radiated emission: 10-m regulations)

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.

SECTION 1

Introduction

This section describes the CPM1A’s special features and functions and shows the possible system configurations. Refer to the Programming Manual (W353) for details on programming actual operation.

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-j/10CDT-D/10CDT1-D CPM1A-20CDR-j/20CDT-D/20CDT1-D (10 I/O terminals) (20 I/O terminals)

CPM1A-30CDR-j/30CDT-D/30CDT1-D CPM1A-40CDR-j/40CDT-D/40CDT1-D

(30 I/O terminals) (40 I/O terminals)

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.

Analog adjustment 0

Analog adjustment 1

24 VDC 0.2 A OUT PUT

The following table shows which IR words are allocated to the analog adjustments on the CPM1A’s CPU Unit.

Input from an input device such as a limit switch

Input bit status

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

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

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.

Main program

MOV

Note When not using as interrupt input terminals, the input bits IR 00003 to IR 00006 can be used as normal input terminals.

! 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 CPU Units

1-2-2 CPU Unit and Expansion Unit

Up to 3 Expansion I/O Units or Expansion Units can be connected to a CPU Unit with 30 or 40 I/O points.

There are three models of Expansion Units available: the Analog I/O Unit, CompoBus/S I/O Link Unit, and Temperature Sensor Units.

Expansion Connector

Expansion I/O Unit, Analog I/O Unit, CompoBus/S I/O Link Unit, or Temperature Sensor Unit)

Expansion I/O Connecting Cable

A PC with 100 I/O points (the maximum) can be assembled by connecting three

Expansion I/O Units.

A PC with 6 analog inputs and 3 analog outputs (the maximum) can be assembled by connecting three Analog I/O Units.

A PC with up to 6 temperature inputs for input from thermocouples or platinum resistance thermometers can be assembled by connecting Temperature Sensor Units.

CompoBus/S I/O Link Units (Slave Units) can be connected to a CPU Unit. I/O data (8 inputs and 8 outputs) is transferred between the CPU Unit and the area allocated to the CompoBus/S Slave. (The I/O data exchanged with the Slave is internal data; there are no external input or output terminals.)

Note Different types of Expansion Units can be connected at the same time. For example, an Expansion I/O Unit, Analog I/O Unit, and CompoBus/S I/O Link Unit, or an Expansion I/O Unit, Analog I/O Unit, and Temperature Sensor Unit can be connected to the CPU Unit.

Expansion I/O Units

Note Only one CPM1A-TS002/TS102 Temperature Sensor Unit can be connected to the CPU Unit. If a CPM1A-TS002/102 is connected to the CPU Unit, only one additional Expansion Unit (other than a CPM1A-TS002/102) or one Expansion I/O Unit can be connected to the CPU Unit.

1-2-3 Host Link Communications

Host Link communications which allows up to 32 OMRON PCs to be controlled from a host computer. The computer-PC connections can be made connectors such as RS-232C and RS-422 Adapters.

1-2-6 CompoBus/S I/O Link Connections

A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The connection is made through a CompoBus/S I/O Link Unit.

From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-

Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O

Unit. The difference is that the bits are not actual I/O points, but I/O bits in the

Master Unit.
