Note

Restoring the EtherNet/IP Unit or Built-inEtherNet/IP Port Setup File from the Memory Card

(Reading and Setting the Data in the Unit)

This operation will create an EtherNet/IP Unit or built-inEtherNet/IP port settings file, and write that file to the Memory Card along with the other backup files. When the Memory Card Power Supply Switch is pressed, the MCPWR indicator on the front of the CPU Unit will flash once and then remain lit while data is being written. If the data is written normally, the MCPWR indicator will turn OFF. The BUSY indicator will flash while the data is being written.

The backup operation will fail if it is performed after the device parameters were not downloaded successfully from the Network Configurator or CX-Pro-grammer. Perform the backup operation only if the device parameters were downloaded normally.

Set pins 7 and 8 of the DIP switch on the front panel of the CPU Unit, as shown in the following table, and turn the power to the CPU Unit OFF and then ON again with the Memory Card inserted into the slot.

This operation will read the EtherNet/IP Unit or built-inEtherNet/IP port setup data file from the Memory Card and restore the data in the EtherNet/IP Unit orbuilt-inEtherNet/IP port.

When the power supply is ON, the MCPWR indicator on the front of the CPU Unit will turn ON, flash once, and then remain lit while data is being read. The BUSY indicator will flash while data is being read. After the data has been read correctly, the MCPWR and BUSY indicators will turn OFF. If the MCPWR indicator flashes five times or if only the BUSY indicator turns OFF, it means that an error has occurred.

Note If the restoration from the Memory Card fails, an “H8” error will be displayed on the7-segmentdisplay on the front panel. If this happens, the data on the Memory Card may not be correct. Confirm that the backup operation was completed normally before performing the restore operation.

Comparing EtherNet/IP Unit or Built-inEtherNet/IP Port Data with the Setup File in the Memory Card

Compare

 

This operation will compare the data in the EtherNet/IP Unit or built-inEther-

Net/IP port setup file in the Memory Card with the device parameters in the

EtherNet/IP Unit or built-inEtherNet/IP port.

When the Memory Card Power Supply Switch is pressed, the MCPWR indicator on the front of the CPU Unit will flash once, and then remain lit while data is being compared. The BUSY indicator will flash while data is being compared. If the data matches, the MCPWR and BUSY indicators will turn OFF. If the MCPWR and BUSY indicators both flash, it means that the data does not match or that an error has occurred.

Note Data backed up for revision 1.1 using a simple backup can be restored to an EtherNet/IP Unit orbuilt-inEtherNet/IP port with revision 2.1, but an error will occur in the comparison. When changing the unit version, refer to6-2-18 Changing Devices for information on the Network Configurator device change function.

Checking Status with the Network Configurator

Section 14-1

14-1Checking Status with the Network Configurator

14-1-1The Network Configurator’s Device Monitor Function

Connect the Network Configurator online, select the device to be checked, right-clickto display thepop-upmenu, and selectMonitor.

 

The Monitor Device Dialog Box will be displayed.

Note

If a communications error occurs during monitoring, the dialog box will con-

 

tinue to show the last information that was collected. To start monitoring

 

again, close the Monitor Device Dialog Box, and then open the dialog box

 

again.

Status 1 Tab Page

The information displayed on the Status 1 Tab Page shows the status of the

 

flags in the following allocated CIO Area words: Unit status 1, Unit status 2,

 

Communications status 1, Communications status 2, and Communications

 

status 3. There will be a check mark in the box when the corresponding flag is

 

ON.

 

In addition, the Target Node Status Field shows the connection status of the

 

target nodes that are connected with the EtherNet/IP Unit as the tag data link

 

originator. The icon will be blue if the connection is normal, or red if an error

 

occurred.

340

Checking Status with the Network Configurator

Section 14-1

Status 2 Tab Page

The Status 2 Tab Page’sTarget PLC Status Field shows the status of the tar-

 

get node PLCs that are connected with the EtherNet/IP Unit as the tag data

 

link originator. The icon will be blue if the CPU Unit is in RUN mode or MONI-

 

TOR mode, gray if it is in PROGRAM mode, or red if an error occurred.

 

The Connected Status of FINS/TCP ConnectionsField shows the status of

 

FINS/TCP connections. There will be a check mark in the box when the corre-

 

sponding connection is established (connected).

341

Checking Status with the Network Configurator

Section 14-1

Note The target PLC status is can be used when the PLC status is selected for all the target sets for both originator and target connections. For those that are not selected, the status will begrayed-out.

342

 

Checking Status with the Network Configurator

Section 14-1

Connection Tab Page

The Connection Tab Page’sTarget Node Status Field shows the connection

 

 

status of the target nodes that are connected with the EtherNet/IP Unit as the

 

 

tag data link originator. The icon will be blue if the connection is normal, or red

 

 

if an error occurred.

 

In addition, the Connection Status Area shows the current status each connection that is set as the originator. This information can be used to identify the cause of tag data link errors. For details on the connection status, refer to

14-3 Connection Status Codes and Error Processing.

343

Checking Status with the Network Configurator

Section 14-1

Error History Tab Page

Controller Error History

Tab Page

The Error History Tab Page displays the error log stored in the EtherNet/IP Unit orbuilt-inEtherNet/IP port. Errors that occurred in the past are recorded, and can be cleared or saved in a computer file as required.

In some cases, error records are cleared when the power is turned OFF, and in other cases the records are retained. For details on the error log, refer to

14-4 Error Log Function.

The error history of the CPU Unit for the EtherNet/IP Unit or built-inEtherNet/ IP port is displayed on this tab page. The error history shows errors that have occurred. It can be cleared or saved in a file in the computer.

344

Checking Status with the Network Configurator

Section 14-1

Refer to the operation manual of the CPU Unit for details on error information.

Tag Status Tab Page

This tab page shows if the tag settings for each tag for tag data links is set so

 

that data can be exchanged with the CPU Unit. The following status is dis-

 

played.

 

 

Ok:

Data was exchanged normally.

 

Processing to solve: The symbol or I/O memory address for the tag is being

 

 

resolved. When the resolution is completed normally, a

 

 

connection will be established and the data exchange

 

 

will start.

 

Area type error:

The area (e.g., EM bank) specified by the tag setting

 

 

does not exist in the CPU Unit. A connection will not be

 

 

established for a tag for which this error occurs.

 

Out of address range: The area specified by the tag setting is outside of the

 

 

area address range in the CPU Unit. A connection will

 

 

not be established for a tag for which this error occurs.

 

Size error:

Different sizes are set for the network symbol and the

 

 

tag settings. Connections will not be opened for tags

 

 

with this error.

 

Not exist:

A network symbol is not set in the symbol table in the

 

 

CPU Unit for the specified tag setting. A connection will

 

 

not be established for a tag for which this error occurs.

 

PLC I/F error:

There is a problem in the bus interface with the CPU

 

 

Unit. Determine the cause based on the indicators and

 

 

the error log.

345

Checking Status with the Network Configurator

Section 14-1

If the status is not “OK,” check the tag data link settings or the network symbol settings in the symbol table in the CJ2 CPU Unit.

346

Using the LED Indicators and Display for Troubleshooting

Section 14-2

Ethernet Information Tab

Page

The Ethernet Information Tab Page shows the communications status at the communications driver level. The error counter information can be used to confirm whether communications problems have occurred. The tag data link information can be used to confirm characteristics such as the bandwidth usage (pps).
