  • Page 22: Telnet

    Figure 3: HyperTerminal Configuration Screen #3 8.2 Telnet The console is also accessible via a Telnet interface for remote administration over Ethernet once the unit is communicating on the network. The Telnet console uses well-known port 23. Note that although only 1 telnet console session can be active at any given time, the telnet console and RS232 console operate independently and can be used simultaneously.

  • Page 23: Command Overview

    Figure 4: Telnet Menu 8.3 Command Overview The console provides standard access and configuration methods for the various network parameters and application configuration parameters supported by the ETH- 100. The number and type of supported console commands may vary with different console version and application version firmware.

Set: The “Set” command actually encompasses several subcommands, each of which allows setting a different configuration parameter. To set a parameter, two arguments are required: the parameter’s name and the value to set it to.

  • Page 25: Console Configuration Backup

    Figure 7: "Show" Command Overview 8.4 Console Configuration Backup The console configuration is backed up in the ETH-100’s battery backed SRAM. This allows the console configuration to be restored upon power-up. Although the battery inside the ETH-100 is rated to last approximately 10 years with no other power supplied to the unit (and longer when power is supplied to the unit), it may eventually require replacement at some point in the product’s lifetime.

  • Page 26: Led Indicators

    9. LED Indicators The ETH-100 unit contains many different LED indicators, each of which conveys important information about the status of the unit, connected drives and Ethernet network. These LEDs and their functions are summarized here. 9.1 Module and Ethernet Indicators The module and Ethernet indicators are located between the MMI port and the Channel A drive port.

  • Page 28: Modbus Tcp/ip

    10. Modbus TCP/IP The ETH-100 interface supports Schneider Electric’s Modbus TCP/IP protocol, release 1.0. The ETH-100 is conformance class 0 and partial class 1 compliant, and allows up to 8 simultaneous Modbus TCP/IP client connections (sockets). Socket timeouts are set to 30s, which means that if a particular open socket experiences no activity for more than 30s, then the interface assumes that the client has experienced some sort of unexpected problem, and the ETH-100 will close that socket.

  • Page 29: Modbus/drive Register Mappings

    Modbus TCP/IP holding register = Toshiba drive register + 1 This means that in order to access a specific Toshiba drive register, simply add 1 to it and access that Modbus TCP/IP holding register. The reason for this offset is due to the fact that Toshiba drive registers begin at number 0, while Modbus holding registers begin at number 1.

  • Page 30: Register Remap Function

    Modbus holding registers and ASD registers (ASD register number + 1 = Modbus holding register number), this can cause certain critical ASD registers to be inaccessible from these clients. Specifically, Toshiba drives typically place communication control registers and status registers in the 0xFAxx to 0xFFxx ASD register region.

    0xFD00 (Modbus holding register 0xFD01), which can therefore be accessed via Modbus holding register 0x0D01 (3329 ) when register remapping is enabled. When register remapping is enabled, only accesses to Modbus registers 0x0A01 – 0x1000 are affected: the normal locations for the critical control and status registers remain unaffected and can still be accessed (i.e.

  • Page 32: Register Access Notes

    “write” scan registers, which use the drive’s RAM data write (“P”) command. For all writes that target the drive’s EEPROM, be sure to follow Toshiba’s guidelines regarding the number of times a specific register can be written without risk of EEPROM damage.

  • Page 33: Performance Tips

    10.8 Performance Tips This section offers several configuration tips which can help to optimize the performance of communications with the ETH-100 and attached drives. 1. Configure Modbus programmable pointer registers to also be drive scan registers. In the example configuration shown in Table 3, Modbus registers FC00 ~ FC07 are configured to point to the ASD scan registers.

  • Page 34

    3. Group read and write registers together in the programmable pointer list and access them with separate Modbus commands. The ETH-100 can process read requests and write requests faster when they are grouped together rather than the master having to issue multiple transactions to access disjoint registers.

The channel select section on this screen will display the currently selected channel and its online/offline status. A channel is defined to be online if a logical connection has been made with an ASD connected to that channel.

  • Page 41: Asd Scan Register Configuration

    11.3.2 ASD Scan Register Configuration Scan Register Setup Information: Scan register values refer to ASD registers, NOT Modbus registers. There are 8 possible scan register values for each of the 3 channels. Not all 8 values need to be configured. The ETH-100 will only mirror those scan registers that have a displayed value.

  • Page 42: Programmable Pointer Registers Configuration

    11.3.3 Programmable Pointer Registers Configuration Modbus Programmable Pointer Register Setup Information: Programmable pointer register values refer to MODBUS registers. There are 16 pointer registers for each of the three channels. Not all 16 registers need to be configured. A pointer register can be accessed by making a request to Modbus registers FC00 ~ FC0F.

  • Page 43: Drive Test Commands

    11.3.4 Drive Test Commands Drive test commands can be used to test the communications between the ETH-100 and your ASD. To run the ASD connected to the currently selected channel, click “Run” and submit a valid frequency command in the “FC” field. Clicking “Run” writes a value of 0xC400 to ASD register 0xFA00 (communication command).

  • Page 44: Firmware Updates

    12. Firmware Updates The ETH-100’s embedded firmware resides in flash memory that can be updated in the field. Firmware updates may be released for a variety of reasons, such as custom firmware implementations, firmware improvements and added functionality as a result of user requests. ICC is continually striving to enhance the functionality and flexibility of our products, and we therefore periodically release new embedded firmware to achieve these goals and meet customer requests.

  • Page 45: Using The Rfu Utility

    12.3 Using The RFU Utility Support for downloading new application firmware to the ETH-100 is provided by the free Rabbit Field Utility (RFU), which is a 32-bit application that runs on Microsoft Windows platforms. The RFU utility can be downloaded from ICC’s home page at http://www.iccdesigns.com.

  • Page 46

    Note: It is possible that certain computers may have difficulty communicating at a sustained 115kbaud rate, which may result in communication errors during firmware downloading. If this occurs, try setting the “baud rate” parameter shown in Figure 19 to a lower value. Figure 19: Communications Options Window Next, select the “Setup…Boot Strap Loaders”...

  • Page 47: Transmitting Firmware Files

    12.3.3 Transmitting Firmware Files When a board support package (BSP) has been downloaded and unzipped, the flash firmware file will be the one with “.BIN” as its file name extension. Once the RFU utility has been configured, the flash firmware files can be downloaded to the ETH-100 by two different methods.

  • Page 48

    When the unit powers up again, it will be running the new application firmware. If the new firmware version release notes indicated that any configuration parameters must be reentered, reenter them again via the console. Also configure any new parameters that are available to match your application requirements. When completed with MMI port use, remove the MMI cable and replace the MMI port dust cover to minimize contamination of the port’s electrical contacts.
