Attach the mounting clip and unit enclosure in your desired manner (refer to page 12 for more information).

  • Page 16: Toshiba Asd (Common Serial) Secondary Network

    4.2 Toshiba ASD (Common Serial) Secondary Network The gateway connects to each drive via the drive’s common serial (logic level) communication port, typically located on either the main drive control board (G7), on the front of the drive enclosure under a small snap-on cover (A7, S9), on the right-hand side of the drive enclosure under a small snap-on cover (S7), or on the bottom side of the drive enclosure (VF-nC1).
  • Page 17 The maximum allowable length for these cables is 5 meters. Although there are many varieties and styles of CAT5 UTP cables available, ICC strongly recommends using only high-quality cables from reputable manufacturers to guarantee optimal noise immunity and cable longevity.

  • Page 20: Rs-485 Electrical Interface

    5. RS-485 Electrical Interface In order to ensure appropriate network conditions (signal voltage levels, etc.), some knowledge of the gateway’s RS-485 network interface circuitry is required. Refer to Figure 7 for a simplified network schematic of the secondary RS-485 interface circuitry. Note that the “Shield” terminal has no internal connection: its purpose is simply to provide a cable shield chaining location between devices.

    “OFF” position is the “up” position. Refer to the indicator markings on the switch. The MAC ID and configured baud rate are read by the DNET-100 only on power-up or after a reset. Therefore, if either of these selections is changed...

  • Page 28: Point Configuration

    “point database”, containing various individual points. A “point” is simply an object that defines some sort of primary -to- secondary network mapping information. In the case of the DNET-100, a point is simply a DeviceNet parameter object, whose characteristics (attributes) are entered by the user via the serial console.

  • Page 29: Parameter Configuration

    12.1 Parameter Configuration As previously mentioned, each data item residing on secondary-network devices must be mapped to a unique DeviceNet parameter object to allow access via the DeviceNet network. This access may take place directly via explicit messaging, or indirectly via I/O messaging. These secondary-network data items are collectively referred to as objects .
  • Page 30 Let’s begin by creating our first DeviceNet parameter, which will map to Modbus register 10 (“frequency command”) on Modbus address 5. Via the DNET-100’s console, we can add a new point, and configure it as follows: DeviceNet parameter......
  • Page 31 (grouping according to device application or function, for example). For instance, if three ASDs were connected to a DNET-100 gateway, parameters #1, #2 and #3 could be assigned as the frequency commands of ASD #1, ASD #2 and ASD #3, respectively.

  • Page 32: I/O Assemblies

    The reason for the 2-byte increment restriction is due to the fact that all secondary-network data object values for protocols supported by the DNET-100 are 16 bits in size. Any valid DeviceNet parameter currently defined in the gateway can be included in the member list of any of the I/O assemblies.
  • Page 33 as members of I/O assemblies. There is no requirement to do this, however: it is perfectly acceptable to define a stand-alone parameter which is not a member of any assembly object definition, and is therefore only accessible via normal parameter object access methods (i.e. explicit messaging). Note that during I/O data exchanges, if the actual consumed data size is less than or equal to a connection instance’s configured consumed connection size, then all received data will be consumed and the connection will produce...
  • Page 34 Once this configuration is complete, we will be able to send command information to, and read status information from, the Modbus devices residing on the DNET-100’s secondary network. If desired, we could have also chosen to utilize the COS/cyclic I/O connection, either instead of the polled I/O connection or in conjunction with it.

  • Page 35: Network Timeout Settings

    DeviceNet network timeout. The item which determines when and how “default value” timeout processing will take place is the “Timeout Mode” selection found in the DNET-100’s Main Menu > Points > DeviceNet Setup menu. Possible values for the Timeout Mode parameter are 0-3, with the following meanings: 0 ..

  • Page 36: General Configuration Procedure

    Value, while those parameter objects that are exclusively members of assembly instance 101 (the COS/cyclic output assembly) will not receive timeout processing regardless of their Default Enable settings. This combination of parameter-specific Default Enable and global Timeout Mode settings allow a relatively complex and specific set of “fail-safe” behaviors to take place when unexpected failure of the DeviceNet network occurs.

  • Page 37: Console Access

    All that is needed is a computer with a standard serial (COM) port, some sort of communications software (such as HyperTerminal, included with Microsoft Windows operating systems), and the included MMI cable (ICC part number 10425). Any communications software and PC will work, provided they support ASCII communications at 38.4kbaud.

  • Page 39 Figure 15: HyperTerminal Configuration Screen #3...

  • Page 40: Invocation

    13.4 Invocation The console provides standard access and editing methods for the various configuration items (points and their associated attributes). It is important to note that unless otherwise indicated, any modifications made to the point database will become effective immediately. However, these changes will only be permanently retained when the current database is saved to a file location: if a change is made to the database and then the gateway is reset without saving those changes, then the active file will be restored upon initialization,...

  • Page 41: Main Menu

    13.5 Main Menu The main menu is shown in Figure 17. All gateway configuration is performed by “drilling down” into progressively lower-level menus. Figure 17: Console Main Menu All navigation and data entry commands are input by simply entering the menu selection number to the right of the “...

  • Page 42: View/Edit Points

    13.5.1 View/Edit Points Main menu selection number 1 displays a screen which shows a summary of the current point (parameter) configuration (see Figure 18). This screen only displays the point mapping information: in order to access a point’s DeviceNet definition information, menu selection number 1 “View/Edit a Point” must be entered with the additional argument of the targeted point number.
  • Page 43 Figure 19: View/Edit a Point Mapping Information: Line 1 indicates the current point mapping information. In Figure 19, it can be seen that DeviceNet Parameter 1 maps to ASD1, parameter FD00 (the ASD’s output frequency). To change the mapping information, enter menu selection number 1 with the additional arguments of the device on which the data object resides and the data object index.
  • Page 44 16 characters are entered, truncation will take place. An example of entering a name would be “ 2 ASD1_output_freq ”. Help: Enter menu selection number 3 with a 24-character (max) string for the parameter’s help string. This field is used only for EDS file generation. If more than 24 characters are entered, truncation will take place.

  • Page 45: Add A New Point

    allowed, then network configuration tools such as RSNetWorx will typically calculate the engineering value via Equation 1: (Actual Value Offset) Multiplier Engineerin Value ( Equation 1 ) Divisor The engineering value can then be displayed to the user in the terms specified within the Precision (menu selection number 15).
  • Page 46 the menu prompt and new point entry string will vary depending on the secondary network. A similar menu prompt when a Modbus secondary network is chosen would be displayed as “ > 2 [ID num] [reg num] ”, and its corresponding new point entry string would therefore be something to the effect of “...

    Figure 21: DeviceNet Setup More Offsets: The assembly object membership list table displays the membership definitions 20 assembly bytes (10 offsets) at a time. If any assembly object size is larger than 20 bytes, menu selection number 3 will display the next group of offsets. When all offsets have been displayed, entering menu selection number 3 will roll back around to the initial offsets page again.

  • Page 49: Save Points

    13.5.2 Save Points Main menu selection number 2 allows the current gateway configuration to be saved to one of the three available file locations in the gateway’s file system. It is important to reiterate that whenever any configuration changes are performed, they are performed only on the gateway’s working memory, and that those changes will be lost unless they are saved to the gateway’s file system prior to exiting the console.

  • Page 50: New Points

    Refer to Figure 23 for an example of loading file “dnet_rtu”. “dnet_rtu” will then also become the active file, and will be the configuration loaded into the gateway’s working memory at the beginning of the next boot cycle. Figure 23: Loading a Point File 13.5.4 New Points Main menu selection number 4 is used to begin a new configuration from scratch.

  • Page 51: Xmodem Point File

    (refer to section 15 for firmware updates). The RTC setting can be changed by entering DNET-100 Information menu selection number 1 with the additional argument of the clock string. The clock string is a specially-formatted string encoded to sequentially contain the information for the current month (mm), day (dd), year (yyyy), hour (hh), minute (mm) and second (ss).

  • Page 56: Exit & Restart

    Figure 31: DNET-100 Information and RTC Setting 13.5.8 Exit & Restart Type “exit” at any menu prompt to reboot the gateway and once again begin communication tasks. Note that whenever you modify the point database and are ready to restart the gateway, you must save the database to the file system prior to restarting or your changes will be lost.
