    1. The Network Gateway Series Concept The MBP-100 is a member of the ICC Network Gateway Series product family. Members of this family are designed to provide a uniform interface, configuration and application experience. This commonality reduces the user’s learning curve, reducing commissioning time while simplifying support. The MBP-100 provides simultaneous support for many different communication protocols, allowing complex interchanges of data among otherwise incompatible networks.

    4.1 RS-485 Network in Use Note that in order to power the unit when not connecting to Toshiba ASDs via the common serial ports, the optional 120VAC/9VDC power supply (ICC part number 10456) or a user-supplied power source meeting the requirements outlined in section 11 must also be installed.

  • Page 16: Toshiba Asd (Common Serial) Network In Use

    4.2 Toshiba ASD (Common Serial) Network in Use 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, S11), 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).

Refer to Toshiba’s documentation for any precautions or notices regarding this connection change. If the LCD panel is already connected via the RS485/RS232 channel, then no change is required.

    5. RS485 Port Electrical Interfaces In order to ensure appropriate network conditions (signal voltage levels, etc.) when using the gateway’s RS485 port, some knowledge of the network interface circuitry is required. Refer to Figure 6 for a simplified network schematic of the RS485 interface circuitry. Note that the “Shield” terminal has no internal connection: its purpose is simply to provide a cable shield chaining location between devices.

  • Page 25: Configuration Switches

    10. Configuration Switches There are eight configuration DIP switches (marked “CONFIG”) located on the front side of the gateway. Switches #1 - #6 set the Modbus Plus station address of the gateway (refer to Table 1). Note that whenever the station addressing switches (#1 - #6) are changed, power must be cycled to the gateway to validate the change.

  • Page 26: Auxiliary Power Supply

    Switches #7 and #8 perform the following functions: Switch #7 ...RS232 port selection switch. When “OFF” at unit startup, the RS232 port will act as the serial console, regardless of the port’s configuration or protocol assignment (refer to section 13 for more information on the serial console).

  • Page 27: Unit Configuration Concepts

    Although each communication port can be configured via the serial console interface, their configuration selections vary slightly. The Toshiba ASD common serial ports have a simple enable/disable selection. The RS232 and RS485 ports can be disabled, or can have one of a selection of control protocols assigned to them.

  • Page 28: Point Configuration

    The selection of what a specific point is to mirror is performed via its “source port” selection. For example, a point may be configured to contain Toshiba ASD parameter mapping and Modbus master ID and register mapping information. However, because both of these protocols act as “master”...

  • Page 29: General Configuration Procedure

    This concept may best be further explained by way of a representative scenario. For example, let’s assume that the gateway’s RS485A port has been designated to be a Modbus Master. Let’s further assume that the “Modbus Master” portion of point #5 indicates an “Address” value of 8 and “Register” value of 14, and that point #5’s “Source Port”...

    13.2 Invocation The console provides standard access and editing methods for the various configuration items (ports, points and their associated attributes). It is important to note that whenever you modify the point database and are ready to restart the gateway (“exit”), you must save the database to the internal file system prior to restarting or your changes will be lost.

    14. Protocol-Specific Information This section will discuss topics that are specific to each of the available network selections. 14.1 Modbus The gateway supports Modbus slave and master functionality via Modbus RTU. The slave implementations share common access methods, which is to say they support the same functions and reference the internal points via a common “Modbus Slave”...

    • Because the transaction is handled locally within the gateway, write data checking is not available. For example, if a write is performed to a register with a data value that is out-of-range of the corresponding “source port” object, no Modbus exception will be immediately returned. However, the point will always reflect the “source port”...

  • Page 52: Modbus Rtu Slave

    For clarity, let’s use Equation 1 and Equation 2 in a calculation example. Say, for instance, that we are going to read coil #34. Using Equation 1, we can determine that coil #34 resides in register #3, as ⎣3.0625⎦ = ⎣3 r1⎦ = 3. Then, using Equation 2, we can determine that the bit within register #3 that coil #34 targets is (34-1)%16 = 1, as 33%16 = mod(2 r1) = 1.

    14.5 Mitsubishi ASD Protocol • The gateway acts as a Mitsubishi protocol master via its RS485 port. Adjustable speed drives such as the FR-A500/E500/F500 series and F700- series that support the Mitsubishi protocol can be accessed. Also supported are MGI Technologies, Inc. M3000, M4000 and M5000-series drives that support the Mitsubishi protocol.

Figure 34: EIA/TIA Wiring Standards RDA SDA SDB RDB Signal (TB:2) Ground (TB:1) (TB:3) Figure 35: PU Port Connections • For 700-series drives, the gateway can connect to the ASD via either the PU (panel) connector as indicated in Figure 35, or via the on-board RS485 terminals.
  • Page 60 (TB:1) Figure 36: 700-Series ASD Connections • Note that although the 700-series ASD also supports the Modbus RTU protocol, the initial ASD firmware did not support the Modbus RTU protocol in 2-wire format. Therefore, using the Mitsubishi protocol may be the only available method to communicate with the gateway (ASD parameter 549 must be “0”).

  • Page 62: Teco-Westinghouse Asds

    14.6 Teco-Westinghouse ASDs The gateway can act as a Modbus RTU protocol master via its RS232 and RS- 485 ports, which allows connection to Modbus-capable Teco-Westinghouse ASDs. While it is possible to connect to any Teco-Westinghouse ASD that supports Modbus (either RS232 or RS485), this section will discuss in particular some important considerations to make note of when connecting to, and interacting with, the PA7300 (with installed PA-M card) and MA7200 ASDs via RS485.

  • Page 63: Pa7300

    • The MA7200 Modbus manual indicates that control data registers (0000H..000FH) are read/write, but reading always returns 0. • All drive parameters may be read at any time, but only Cn parameters can be written while the inverter is in DRV mode. The inverter must be in PRG mode to write any other parameters.

    In this case, we are accessing 32 words of global data, so set the bottom portion of the MSTR instruction (“number of registers”) to 32. In the case of MSTR global reads, this number cannot exceed 32 by definition. Initiate the global read command by closing internal relay 1. The data response will be seen in the MSTR Data Area (starting at register 40300).

    16. Firmware Updates The gateway’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.
