NX-series Analog I/O Units User’s Manual for Analog Input Units and Analog Output Units (W522)

Warnings

WARNING

During Power Supply

Do not touch the terminal section while power is ON.

Electric shock may occur.

Do not attempt to take any Unit apart.

In particular, high-voltage parts are present in Units that supply power while power is supplied or immediately after power is turned OFF. Touching any of these parts may result in electric shock. There are sharp parts inside the Unit that may cause injury.

Safety Precautions

Fail-safe Measures

Provide safety measures in external circuits to ensure safety in the system if an abnormality occurs due to malfunction of the CPU Unit, Industrial PC, other Units, or slaves or due to other external factors affecting operation.

Not doing so may result in serious accidents due to incorrect operation. Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must

be provided in external control circuits.

The CPU Unit or Industrial PC will turn OFF all outputs from Output Units in the following cases. The remote I/O slaves will operate according to the settings in the slaves.

• If a power supply error occurs.

• If the power supply connection becomes faulty.

• If a CPU watchdog timer error or CPU reset occurs.

• If a Controller error in the major fault level occurs.

• While the CPU Unit is on standby until RUN mode is entered after the power is turned ON

External safety measures must be provided to ensure safe operation of the system in such cases.

The 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 safe operation of the system.

If external power supplies for slaves or other devices are overloaded or short-circuited, the voltage will drop, outputs will turn OFF, and the system may be unable to read inputs. Provide external safety measures in control with monitoring of external power supply voltage as required so that the system operates safely in such a case.

You must take fail-safe measures to ensure safety in the event of incorrect, missing, or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.

Not doing so may result in serious accidents due to incorrect operation.

Voltage and Current Inputs

Make sure that the voltages and currents that are input to the Units and slaves are within the specified ranges.

Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.

Transferring

Always confirm safety at the destination node before you transfer Unit configuration information, parameters, settings, or other data from tools such as the Sysmac Studio.

The devices or machines may operate unexpectedly, regardless of the operating mode of the Controller.

Cautions

Wiring

When you connect a computer or other peripheral device to a Communications Coupler Unit that has a non-isolated DC power supply, either ground the 0-V side of the external power supply (i.e. Unit power supply) or do not ground it at all.

If the peripheral devices are grounded incorrectly, the external power supply (i.e. Unit power supply) may be short-circuited.

Never ground the 24-V side of the power supply, as shown in the following figure.

Be sure that all terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals. The loose screws may result in fire or malfunction.

Precautions for Safe Use

Wiring

• Double-check all switches and other settings and double-check all wiring to make sure that they are correct before turning ON the power supply. Use the correct wiring parts and tools when you wire the system.

• Do not pull on the cables or bend the cables beyond their natural limit. Also, do not place heavy objects on top of the cables or other wiring lines. Doing so may break the cable.

• When wiring or installing the Units, do not allow metal fragments to enter the Units.

• Do not press the flat-blade screwdriver straight into the release holes on a screwless clamping terminal block. Doing so may damage the terminal block.

NG OK

• When you insert a flat-blade screwdriver into a release hole on a screwless clamping terminal block, press it down with a force of 30N or less. Applying excessive force may damage the terminal block.

• Do not incline or twist the flat-blade screwdriver while it is in a release hole on a screwless clamping terminal block. Doing so may damage the terminal block.

NG NG

• Use crimp terminals for wiring the M3 screw terminal blocks. Do not connect bare stranded wires directly to the M3 screw terminal blocks.

Power Supply Design

• Use all Units within the I/O power supply ranges that are given in the specifications.

• Use the I/O power supply current for the CPU Rack of the NX-series NX1P2 CPU Unit at 4 A or less. Using the currents that are outside of the specifications may cause failure or damage.

• Supply sufficient power according to the contents of this manual.

• Use the power supply voltage that is specified in this manual.

• Do not apply voltages that exceed the rated value to any Input Unit.

• Do not apply voltages or connect loads to the Output Units or slaves in excess of the maximum ratings.

• Inrush current occurs when the power supply is turned ON. When selecting fuses or breakers for external circuits, consider their fusing and detection characteristics as well as the above precautions and allow sufficient margin in shut-off performance.

• Install external breakers and take other safety measures against short-circuiting and overcurrents in external wiring.

Turning ON the Power Supply

• When you set the Operating Mode at Startup, confirm that no adverse effect will occur in the system.

Precautions for Safe Use

Actual Operation

• Before you start operation, always register the NX Units that are connected to the Communications Coupler Unit in the host communications master as the Unit Configuration Information.

• Check the user program, data, and parameter settings for proper execution before you use them for actual operation.

• If you change the fail-soft operation setting, the output status when the error occurs may also change. Confirm safety before you change the fail-soft operation setting.

• If you use fail-soft operation, write programming to determine whether Unit I/O data is valid. Without such programming, the user program cannot distinguish between Units for which I/O refreshing is continued and Units for which I/O refreshing is stopped.

Turning OFF the Power Supply

• Do not disconnect the cable or turn OFF the power supply to the Controller or a Slave Terminal when downloading data or the user program from the Support Software.

• Always turn OFF the external power supply to the Units before attempting any of the following.

Mounting or removing an NX Unit, Communications Coupler Unit, CPU Unit, or Industrial PC Assembling Units Setting DIP switches or rotary switches Connecting or wiring cables Attaching or removing terminal blocks or connectors

Units that supply power continue to supply power to the Units for up to several seconds after the power supply is turned OFF. The PWR indicator remains lit as long as power is supplied. Confirm that the PWR indicator is not lit before you perform any of the above.

Operation

• Confirm that the controlled system will not be adversely affected before you perform any of the following operations.

Changing the operating mode of the CPU Unit or the Industrial PC (including changing the setting of the Operating Mode at Startup) Changing the user program or settings Changing set values or present values Forced refreshing

• Always sufficiently check the safety at the connected devices before you change the settings of a slave or Unit.

General Communications

• Do not exceed the ranges that are given in the specifications for the communications distance and number of connected Units.

• Refer to the user’s manual for the Communications Coupler Unit for precautions for the safe use of communications with the connected Communications Coupler Unit.

Regulations and Standards

Conformance to EU Directives

Applicable Directives

• EMC Directives

• Low Voltage Directive

Concepts

z EMC Directives

OMRON devices that comply with EU 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.*1

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 EU 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.

*1. Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN 61131-2 EMI (Electromagnetic Interference): EN 61131-2 (Radiated emission: 10-m regulations).

z 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. The applicable directive is EN 61010-2-201.

z Conformance to EU Directives

The NX-series Units comply with EU Directives. To ensure that the machine or device in which the NX-series Units are used complies with EU Directives, the following precautions must be observed.

• The NX-series Units must be installed within a control panel.

• You must use SELV power supply for the DC power supplies that are connected as the Unit power supplies and I/O power supplies for the NX-series Units.

We recommend that you use the OMRON S8VK-S series Power Supplies for the CPU Racks with NX-series NX1P2 CPU Units. We recommend that you use the OMRON S8JX-series Power Supplies for Slave Terminals. EMC standard compliance was confirmed for these recommended Power Supplies.

• NX-series Units that comply with EU Directives also conform to the Common Emission Standard (EN 61131-2). 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 in which the NX-series Units are used complies with EU Directives.

• You must use power supplies with an output hold time of 10 ms or longer for the DC power supplies that are connected as the Unit power supplies and I/O power supplies for the NX-series Units.

NX-series Analog I/O Units User’s Manual for Analog Input Units and Analog Output Units (W522)

1 Features and System Configuration

Synchronous I/O with Refresh Cycle of the NX Bus

When the NX-series CPU Unit or EtherCAT Coupler Unit is used together with NX Units that support synchronous I/O refreshing, the I/O control of multiple NX Units can be synchronized at the time to synchronize with the refresh cycle of the NX bus.

This provides an accurate I/O control because it suppresses jitter in the I/O timing of multiple NX Units.

1-1 Features and Applications

Simple I/O Wiring with a Screwless Clamping Terminal Block

The terminal block is a screwless clamping terminal block.

You can connect the wires simply by pushing the ferrules into the terminals. The amount of wiring work is reduced without requiring the use of screws.

1-1-2 Applications of the Analog Input Units and Analog Output Units

This section describes the applications of the Analog Input Units and Analog Output Units.

Precautions for Safe Use

4-2-2 Calculating the Total Current Consumption from I/O Power Sup-

ply

The total current consumption of I/O power supplied from the NX bus must be within the range of the maximum I/O power supply current of the Communications Coupler Unit or the Additional I/O Power Supply Unit. However, for a CPU Rack, the specification for the maximum I/O power supply current is restricted regardless of the model of the Additional I/O Power Supply Unit. Refer to the hardware user's manual for the CPU Unit to which NX Units are connected for information on the restrictions for the CPU Rack.

To confirm this and to calculate the I/O power supply capacity, calculate the total current consumption from I/O power supply from the NX bus.

The total current consumption from I/O power supply from the NX bus is the total sum of current consumption from I/O power supply of the NX Unit that supplies the I/O power from the NX bus, the current of each applicable I/O circuit, and current consumption of any connected external devices.

4-2 Power Supply Types and Wiring

Note that the current consumption from I/O power supply indicated in the data sheet for each Unit type does not include the load current of any external connection load and current consumption of any connected external devices.

The total current consumption from I/O power supply of the Analog Input Units and Analog Output Units is calculated as follows:

z Total Current Consumption from I/O Power Supply of the Analog Input Units

= (Current consumption from I/O power supply of the Analog Input Units) + (Total current consumption of connected external devices)

z Total Current Consumption from I/O Power Supply of the Analog Output Units

= (Current consumption from I/O power supply of the Analog Output Units) + (Total current consumption of connected external devices)

Refer to A-1 Data Sheet on page A-2 for the current consumption from the I/O power supply for the individual Analog Input Units and Analog Output Units.

4-2-2 Calculating the Total Current Consumption from I/O Power Supply

Use the I/O power supply current for the CPU Rack of the NX-series NX1P2 CPU Unit at 4 A or less. Using the currents that are outside of the specifications may cause failure or damage.

Preventing Incorrect Attachment of Terminal Blocks

In order to prevent unintentionally installing the wrong terminal block, you can limit the combination of a Unit and a terminal block.

Insert three Coding Pins (NX-AUX02) into three of the six incorrect attachment prevention holes on the Unit and on the terminal block. Insert these pins into positions so that they do not interfere with each other when the Unit and terminal block are connected to each other.

You can use these pins to create a combination in which the wrong terminal block cannot be attached because the pin patterns do not match.

4-3 Wiring the Terminals

z Types of Coding Pins

There are two types of Coding Pins, both with their own unique shape: one for terminal blocks and one for Units.

Three pins come with each runner.

4-3-2 Checking the Wiring

Check the wiring by reading input data or writing output data from Slave Terminals using the Watch Tab Page of the Support Software.

For Input Units, you can turn ON/OFF the inputs from external devices that are connected to the target Units and monitor the results.

For Output Units, you can execute the I/O outputs of the target Units and check the operation of the connected external devices.

For details on monitoring and I/O output operations using the Support Software, refer to the operation manual for the Support Software that you are using.

• In the Sysmac Studio, you can check the wiring from the I/O Map or Watch Tab Page. If you use the I/O Map, you can also monitor and perform forced refreshing even if the variables are not defined or the algorithms are not created. Therefore, you can easily check the wiring. Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for details on monitoring and forced refreshing operations.

• Some Communications Coupler Units support I/O checking that allows you to check wiring with only the Slave Terminal. Refer to the user’s manual of the Communications Coupler Unit for detailed information on the support and functionality of I/O checking for your Communications Coupler Unit.

Shield

Ground of 100 Ω or less

Do not ground the shield on the output device.

It is not necessary to connect the shield normally. However, if noise affects the Unit, ground the end of the shield on the Input Unit side. In this case, do not connect the end of the shield anywhere on output device.

You can use the NX-TBX01 Shield Connection Unit to ground more than one shield.

Connect the shield of the cable to the SHLD terminal. And ground the functional ground terminal to 100 Ω or less.

To ensure this NX Unit is kept in the best operating condition, observe the following points when wiring to avoid the effects of the noise.

• Use a shield wire (2 conductors, twisted wire) or a shield wire (3 conductors) as the input connection line for each input. Use the shield without connecting to anything normally.

• Wire the input connection lines and power lines (e.g., AC power supply lines or power lines) separately. Do not place such lines in the same duct.

• Insert a noise filter into the power supply input section if noise comes from power supply lines when using the same power supply to power an electrical welder or an electric discharge machine, or there is a high-frequency source nearby.

4-4-3 Precautions when Using Common Power Supply for Input

Devices of Analog Input Units

If you use Analog Input Units that take differential input, when more than one input device is using the same power supply, and voltage input is being supplied, a disconnection will occur as follows.

If a disconnection occurs in section A in the figure above, unwanted voltage paths occur as indicated by the arrow. As a result, about 1/3 to 1/2 of the voltage between C and D, which is normally connected, is generated between A and B. The same applies when B is disconnected.

When this kind of voltage is generated, disconnection detection may not work.

When voltage input is being supplied, either set up the input devices so that they are not using the same power supply, or use isolators for each input.

This does not apply when current input is being supplied.
