Overview

The 460EAV Gateway device seamlessly connects up to ten Altivar Drives to an EtherNet/IP client such as

a ControlLogix® PLC. By following this guide, you will be able to configure the 460EAV Gateway for

basic operation. You will set the device’s network settings and parameters to the proper configuration for

initial operation and physically place the device in the network.

For further customization and advanced use feel free to consult the provided 460 User Manual. In

addition, Real Time Automation would be happy to provide support to help you utilize the device.

Port Connections

The factory default port settings on the 460EAV gateway are for Port 0 (T-strip) to be set to RS485 and

Power while Port 1 (DB-9) is set to RS232 by default.

If these default port settings are incompatible with your equipment they can be configured differently. For

assistance changing port configurations contact our customer support department. For specific jumper and

pin settings refer to the end of this manual, appendix A.

Accessing the Main Page

The network settings must be configured to access the gateway’s Main Page. The Main Page allows the

user to edit the parameters which are required to connect the desired devices. The following steps will

connect the gateway to the network properly.

1) Connect the 7-30 VDC power source to the device via the T-strip.

2) Using the crossover cable connect the device to the PC. (If you are connecting through a hub or

switch use a standard Ethernet cable.)

3) Insert the provided CD-ROM.

4) Run the IPSetup program from the CD-ROM.

5) Configure the IP Address of the unit for your

subnet. (Ex: If your workstation IP address is

192.168.0.1 an acceptable IP Address for the

gateway would be 192.168.0.100.)

6) Click Set.

NOTE

Browser configuration is only Internet

Explorer compatible. The use of

FireFox is not supported.

Default IP address is 192.168.0.100

Error: Main Page Does Not Launch

If the main page does not launch the IP Address is most likely incorrect. Correct the IP Address and try

again. If you do not know the IP address use the following procedure:

1) Open an MS-DOS Command Prompt.

2) Type ipconfig and press enter.

3) Note the IP Address. (The previous example was 192.168.0.1)

4) To test the communication between the PC and the uni, type ping (###.###.#.###) in the prompt

and press enter. The (###.###.#.###) is a placeholder for the IP Address you used in step 5 of

network configuration which was192.168.0.100. If the device is connected to the network the ping

will show a response. If you get no response check the crossover cable and any other network

devices.

Modbus RTU Master Settings

Now that the device is on the network you will configure the device settings. As a reminder you will need

to know the connector type, mode, baud rate, parity, data bits and stop bit settings of your Modbus RTU

slave device in order to complete device configuration.

1) If you would like to change the device description, click Edit in the Description row on the main

page. Otherwise, skip to step 4.

2) Type the desired description into the text box.

3) Click Save.

4) In the Selected Communication Modules row, click Edit.

5) In the Modbus RTU Master row, click Edit.

6) Verify that the Enabled box is checked.

7) The Response Timeout and Delay Between Polls default to 500 and 50 milliseconds respectively. To

customize the values enter the new time in milliseconds.

8) Select the appropriate settings in the Connector, Mode, Baud, Parity, Data and Stop fields. The

settings should match your Modbus RTU slave device.

9) Click Save to save your configuration.

10) Click Return to Main Page.

If your data is not flowing correctly after installing the device on the

network, check that the settings selected match the settings of your Modbus

Slave device. Incorrect settings will skew operation.

5) In the Slave Address enter the Modbus unit ID that corresponds to your Modbus Slave Device.

6) If you need to change the word order for values that are 4 bytes check the box labeled Swap

Words.

The maximum length of registers per single read/write request is 16 regis-

ters. You cannot configure more than 160 registers across all devices for

Data In. The same limit applies to Data Out.

7) For Data In select the type of data to read. (Coil Status, Input Status, Input Register, or Holding Reg-

ister). The Point Type/Data Type values will match the data types of the Modbus RTU slave device.

(Continued on page 12)

1st reg. = 0x2000

2nd reg. = 0x4397 1st reg. = 0x4397

2nd reg. = 0x2000

Swap Words Example:

With the value 302.25 mapped as a floating value.

8) Enter the starting address of the read beneath the “Addr” column. Enter the Length of the read mes-

sage beneath the “Len” column. (Length is the number of selected data types to be read/written. It is

not the number of registers.)

9) For Data Out select the type of data to write. (Coil Status or Holding Register)

10) Enter the starting address of the write and the length of the write message.

11) When all required parameters are entered click Save.

To delete the entire slave device click Clear.

To return to the Main page and abandon all changes click Cancel.

12) You will need to Reboot and Refresh the unit after each modification.

Setting up the PLC

Before the 460EAV Gateway can communicate with a Programmable Logix Controller (PLC) you must

configure the PLC settings to expect to read and/or write data from the gateway. Use the following

information to configure the PLC.

♦ ThenewmoduletypeshouldbeaGenericEthernetmodule.

♦ WerecommendaRequestedPacketInterval(RPI)of100.0ms.

Confirming Data Transmission

To check the status of the devices and to see the data that has been transmitted use the following steps:

1) On the Main Page click on the Status and Summary button located on the left hand side of the

screen.

2) The 460EAV Device Summary and Status page will be shown.

3) The device drop down menu allows you to switch between the different devices and to display

statuses.

4) Under Show you can choose to view only values that are greater than zero by checking the Only

Non-Zero Values checkbox.

5) The Device Status section displays whether or not the device is connected and enabled.

Verifying Gateway Communication

If the device is not physically connected correctly or if the device parameters are incorrect the Device

Status will display Enabled NOT Connected. If you receive this error verify that the devices are

connected properly.

If your Modbus Master settings do not match the slave settings the TimeoutMsgCount value will increase

each time the status page is refreshed.

If there are errors they will be displayed in the ErrorMSGCount field.

Verifying PLC Communication

To check the status of the Modbus RTU devices from the Ethernet/IP Client side use the following steps:

1) From the PLC program select the option to view Controller Tags.

2) Scroll down to tag 198 for the RTA_460EAV:I.DATA.

3) To check the status of each of the 12 devices on the network look at the last two words (198 and

199) of the Input Assembly Area. Each of the 12 devices is represented by a bit. If that device’s bit

is 1 then the status of that device is fine. If the device’s bit is 0 either an error or a timeout has

occurred, or the unit is not configured correctly.

Device 1 Status=Bit 0 in Register 199 … Device 32 Status=Bit 15 in

Device Data Mapping

To communicate between Altivar drives and an EtherNet/IP scanner the 460EAV uses two data buffers. The

input assembly 100 buffer contains input data transferred from an Altivar drive to an EtherNet/IP scanner.

The output assembly 112 contains output data transferred from an EtherNet/IP scanner to an Altivar drive.

Bytes 0 through 319 are set aside for the Altivar device data, which is defined in the web server. You

configure the register list which is read from and written to each device. The data is then mapped to the

input and output device buffers of the 460EAV where it is exchanged with the EtherNet/IP scanner.

Bytes 320 through 395 are used for pass-through messaging (PTM). PTM is a feature that allows you to

send any Modbus command from an EtherNet/IP scanner to an Altivar. Any message sent from the Altivar

network is routed to the EtherNet/IP scanner in the output buffer. The 460EAV performs no validation or

inspection on the pass-through message or the response message. (See Example Pg. 21)

Bytes 396 through 399 of the input buffer provide status data for each Altivar device.
