Power Supply Design

• Select an external power supply with sufficient capacity by considering the power supply capacity or inrush current when the power is turned ON that is specified in this manual. Otherwise, the external power supply may not be turned ON or malfunction due to unstable power supply voltage. Use the I/O power supply current at 4 A or less. Using the currents that are outside of the specifica-

• tions may cause failure or damage.

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

• Surge current occurs when the power supply is turned ON. When selecting fuses or breakers for external circuits, consider the above precaution and allow sufficient margin in shut-off performance. Refer to this manual for surge current specifications.

• If the full dielectric strength voltage is applied or turned OFF using the switch on the tester, the generated impulse voltage may damage the Power Supply Unit. Use the adjustment on the tester to gradually increase and decrease the voltage.

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

• Use the I/O power supply capacity within the range that is given in the Unit specifications.

• Provide suitable power supply capacity according to the reference manuals.

• Use the power supply voltage that is specified in the related manuals.

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

NX-series Safety Control Unit/Communication Control Unit User's Manual (Z395)

Precautions for Safe Use

Debugging

• With forced refreshing, the values of variables are overwritten with specified values and then the safety programs are executed. If forced refreshing is used for variables that give the results of program processing, the variables will first take the specified values, but they will then be overwritten by the safety program.

•

Depending on the difference in the forced status, the control system may operate unexpectedly.

• After you clear the memory, the Controller operates in the same way as immediately after you create the system configuration with the Controller in the factory default condition.

• Verify that the safety communications with a remote node will be established in the debug mode of the Safety CPU Unit.

Turning ON the Power Supply or Restarting after Safety Validation

• Remember that if safety validation is successful, the next time the Safety CPU Unit is started, it will automatically start in RUN mode.

•

When you download the parameters for the Communication Control Unit and NX Units, the Safety CPU Unit automatically restarts.

Turning ON the Power Supply

• Double-check all wiring connections and switch settings to make sure that they are correct before turning ON the power supply

• 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 damage the Units or slaves or cause fire.

• It takes approximately 20 seconds for the Communication Control Unit to start up after the power supply is turned ON. During that time, digital outputs on the CPU Rack will be OFF. Note that the slave outputs will behave according to the setting values. Use the system-defined variables and the NX Unit device variables in the user program to confirm that I/O data communications are established before attempting control operations. During the startup process, communications with external devices will not be established.

• Configure the external circuits so that the power supply to the control system turns ON only after the power supply to the Controller has turned ON. If the power supply to the Controller is turned ON after the control power supply, temporary errors may result in incorrect control system signals because the output terminals on Output Units may momentarily turn ON when power supply is turned ON to the Controller.

• You cannot obtain normal input data from NX Units while the Units are restarting. Use device variables for the NX bus master of the Communication Control Unit in the user program to check the validity of the I/O data before you attempt control operations.

. Use the correct wiring parts and tools when you wire the system.

Actual Operation

• The relevant Units will maintain the safe states for I/O data with safety connections after an error is detected in safety process data communications. However safety process data communications will recover automatically.

NX-series Safety Control Unit/Communication Control Unit User's Manual (Z395)

, when the cause of the error is removed,

Precautions for Safe Use

If you need to prevent equipment from restarting when safety process data communications recover automatically

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

, implement suitable restart conditions in the user program.

Turning OFF the Power Supply

• Never turn OFF the power supply to the Controller when the BUSY indicator is flashing. While the BUSY indicator is lit, the settings in the Communication Control Unit are being backed up in the built-in non-volatile memory OFF. Also, a major fault level Controller error will occur the next time you start operation, and operation will stop.

• Do not turn OFF the power supply or remove the SD Memory Card while SD Memory Card access is in progress (i.e., while the SD BUSY indicator flashes). Data may become corrupted, and the Controller will not operate correctly if it uses corrupted data. To remove the SD Memory Card from the Communication Control Unit while the power supply is ON, press the SD Memory Card power supply switch first. Make sure that the SD BUSY Indicator and the SD PWR Indicator are turned OFF before you remove the SD Memory Card.

• If the Unit power supply is turned OFF before the I/O power supply for the control system is turned OFF, the output terminals of Output Units may malfunction and the control system may perform incorrect output temporarily. To avoid this problem, configure the external circuit to make sure that the Unit power supply is turned OFF only after the power supply for the control system is turned OFF.

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

• Always turn OFF the power supply to the Controller before you attempt any of the following. a) Mounting or removing an NX Unit, Communication Control Unit b) Assembling Units c) Setting DIP switches or rotary switches d) Connecting or wiring cables e) Attaching or removing terminal blocks or connectors The Power Supply Unit may continue to supply power to the Controller for a few seconds after the power supply turns OFF. The UNIT PWR and I/O PWR indicators are lit during this time. Confirm that the UNIT PWR and the I/O PWR indicators are not lit before you perform any of the above actions.

. This data will not be backed up correctly if the power supply is turned

Operation

• Confirm that no adverse effect will occur in the system before you attempt any of the following. a) Changing the operating mode of the Safety CPU Unit b) Changing the user program or settings c) Changing set values or present values d) Forced refreshing e) Restarting a slave or Unit after you change any settings

NX-series Safety Control Unit/Communication Control Unit User's Manual (Z395)

Precautions for Safe Use

f) Transferring a backup file on the SD Memory Card

•

After you change any slave or Unit settings, carefully check the safety of the controlled system before you restart the Unit.

• If two different function modules are used together, such as when you use an EtherNet/IP Function Module and an NX Bus Function Module, take suitable measures in the user program and external controls to ensure that safety is maintained in the controlled system if one of the function modules stops. The relevant outputs will behave according to the slave or Unit specifications if a partial fault level error occurs in one of the function modules.

General Communications

• When you use data link communications, check the error information that is given in _ErrSta (Controller Error Status) to make sure that no error has occurred in the source device. Create a user program that uses reception data only when there is no error in the source device. If there is an error in the source device, the data for the data link may contain incorrect values.

•

If an error occurs in tag data link communications or communications between NX Units, this product continues refreshing variables with the last values that it receives.

• Unexpected operation may result if inappropriate data link tables are set. Even if appropriate data link tables have been set, confirm that the controlled system will not be adversely affected before you transfer the data link tables. The data links start automatically after the data link tables are transferred.

EtherNet/IP Communications

• Before using I/O data, confirm that this product serves your purpose, in consideration of the following specifications of tag data link communications for this product. a) If an error occurs in tag data link communications, this product continues refreshing variables

with the last values that it receives.

b) If an error occurs in tag data link communications, the Omron EtherNet/IP Originator automati-

cally restores the communications after resolving the cause of the error

c) This product cannot monitor the target connection status. If you use this product as a target de-

vice, make sure to use the originator to check the connection status.

• Make sure to use the communications distance, number of nodes connected, and method of connection for EtherNet/IP within specifications. Do not connect EtherNet/IP communications to EtherCAT or other networks. An overload may cause the network to fail or malfunction.

• All related EtherNet/IP nodes are reset when you transfer settings for the built-in EtherNet/IP port (including IP addresses and tag data links settings). The settings can only be enabled after the reset. Confirm that the system will not be adversely affected by resetting nodes before you transfer the settings.

• If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the communications load on the network will increase. This will increase collisions and may prevent stable communications. Do not use repeating hubs on networks where tag data links are used. Use an Ethernet switch instead.

NX-series Safety Control Unit/Communication Control Unit User's Manual (Z395)

Precautions for Safe Use

Restoring Data

• You cannot back up, restore, or compare some or all of the settings for certain slaves and Units. Also, you cannot back up, restore, or compare data for disabled slaves or Units. After you restore data, suf

ficiently confirm that operation is correct before you start actual operation.

Transferring Programs

• Always confirm safety at the connected equipment before you perform the download when the device output hold configuration is set to enable. The equipment may operate unexpectedly because the last status for outputs is retained.

Standards

• The customer is responsible for attaining conformance of the entire system to standards.

Maintenance

• Test the functionality every six months to detect welded contactor contacts. T

o detect electrical and mechanical failures, use a combination of redundant semiconductor output

contacts and redundant mechanical output devices.

Unlike the ladder diagram language, the FBD language does not have bus bars, and the connecting lines represent the flow of inputs and data rather than the power flow Algorithms are executed in order from top to bottom in units that are called networks. A network consists of configuration elements that use connecting lines to connect inputs to outputs. The FBD language does not have an END instruction. Execution for the task period ends when the last network is executed. You use the FBD language to write safety programs for the Safety CPU Unit.

user program All of the programs that are created by the user. User program refers to the programs for

standard controls of the standard controller and the safety program of the Safety CPU Unit.

operating mode The status of the Safety CPU Unit, when it is in normal operation, that the user changes to

run or check the operation of the Safety CPU Unit. There are the three modes: PROGRAM mode, DEBUG mode, and RUN mode.

3 Specifications of Configuration Units

The inrush current may vary depending on the operating condition and other conditions. Therefore, select fuses, breakers, and external power supply devices that have enough margin in characteristic and capacity considering the condition under which the devices are used. Especially when you turn the power ON/OFF through a switch inserted to the external DC power supply, cycling power ON-OFF-ON within one second will cause the inrush current of approx. 30 A/0.3 mA to occur since the inrush current limiter circuit fails to limit the current.

*5. The amount of current that can be passed constantly through the terminal. Do no exceed this current value

when you use a through-wiring for the Unit power supply.

Precautions for Safe Use

• Never turn OFF the power supply to the Communication Control Unit when the BUSY indicator is flashing. While the BUSY indicator is flashing, a backup of the setting values into the built-in non-volatile memory is in progress. If you turn the power OFF during that time, the backup will fail. In addition, the controller error in the major fault level occurs at the next startup, which causes the operation to stop.

•

Never turn the power OFF or remove the SD Memory Card while the card is in use (SD BUSY indicator is flashing). This may cause data corruption, and the data may not work as intended. To remove the SD Memory Card from the Communication Control Unit while the power supply is ON, press the SD Memory Card power supply switch first. Make sure that the SD BUSY Indicator and the SD PWR Indicator are turned OFF before you remove the SD Memory Card.

The status indicators for the Communication Control Unit (RUN, ERROR, BUSY, SD PWR, and SD BUSY indicators) allow you to check the operating status of For details on how to check the operating status of the Communication Control Unit, refer to 15-1 Op- eration after an Error on page 15-2.
