13 In all cases, the unit can be easily unsnapped from the mounting clip to temporarily provide easier access to the chassis ground terminal or netw ork connector.[...]

14 4. Installing the Ga tew ay The gateway’s installation procedure w ill vary slightly depending on the chosen mounting method and the netwo rks that w ill be used. 4.1 RS-485 Network in Use Note that in order to power the unit w hen not connecting to Toshiba ASDs via the common serial ports, the optional 120VAC/9VDC pow er supply (ICC part numb[...]

15 4.2 Toshiba ASD (Common Serial) Network in Use The gateway connects to each drive via t he 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 sm[...]

16 4. Remove the drive’s front cover / open the drive’s cabinet door (refer to the appropriate drive manual for instructions how to do this). 5. The drive’s LCD panel (also called the “Electronic Operator Interface” or “EOI”) can communicate w ith the drive via either the RS485/RS232 channel (CNU1/CNU1A) or the comm on serial channel [...]

17 ICC or your local Toshiba represent ative for assistance if the problem persists. 4.2.2 Installation for S7, S9, S11, A7 and VF-nC1 ASDs 1. Mount the unit via the desired method (refer to page 12 for more information). 2. CAUTION! Verify that all input pow er sources to the drives to be connected have been turned OFF and are locked and tagged ou[...]

18 9. Take a moment to verify that the gatew ay and all netw ork cables have sufficient clearance from drives, motors, or power-carry ing electrical wiring. 10. Turn the power sources to all c onnected drives ON, and verify that the drives function properly. If the drives do not appear to pow er up, or do not function properly, immediately turn pow[...]

19 5. RS485 P ort Electrical Interfaces In order to ensure appropriate netwo rk conditions (signal voltage levels, etc.) when using the gatew ay’s RS485 port, some know ledge of the network interface circuitry is required. Refe r to F igure 6 for a simplified network schematic of the RS485 interf ace circuitry. Note that the “Shield” terminal[...]

21 7. Maintenance and Inspection Preventive maintenance and inspection is r equired to maintain the gateway in its optimal condition, and to ensure a long operational lifetime. Depending on usage and operating conditions, perform a periodic inspection once every three to six months. Before starting ins pections, disconnect all pow er sources. Inspe[...]

22 8. Stor ag e and War r anty 8.1 Storage Observe the following points w hen the gat eway is not used immediately after purchase or when it is not us ed for an extended period of time. • Avoid storing the unit in places that are hot or humid, or that contain large quantities of dust or metallic dust. Store the unit in a w ell-ventilated location[...]

23 9. LED Indica tor s The gateway contains several different LED indicators, each of which conveys important information about the status of the unit and connected netw orks. These LEDs and their functi ons are summarized here. 9.1 Toshiba ASD Common Serial Port Indicators Each Toshiba ASD common serial port RJ45 connector contains two integrated [...]

24 10. Conf igur a tion Switc hes There are eight configurat ion 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, pow er must be cycled to the gateway to valid[...]

25 Switches #7 and #8 perform the follow ing functions: Sw itch #7 .........R S232 port selection switch. W hen “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). When “ON” at unit startup, the[...]

26 12. Unit Conf igur a tion Concepts 12.1 Port and Protocol Configuration Each of the communication ports can be individually configured or enabled/disabled. It is important to not e that w ith one exc eption, the ports function independently of one another, and can operate simultaneously . For example, a Modbus RTU slave reques t on the RS485 por[...]

27 The default timeout time in all cases is 0, which disables netw ork timeout handling. When nonzero, timeout proce ssing does not begin until after a valid netwo rk packet has been received by the unit on that port. When the timeout time is nonzero and a communication interruption is detected, the timeout enable selections for each point are insp[...]

28 This concept may best be further ex plained by way of a representative scenario. For example, let’s assume that the gatew ay’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?[...]

29 1. Access the serial console configuration interface via Hyperterminal or other text-based console program. 2. Assign (or enable/disable) the desired protocols and their characteristics to the specific communication ports. 3. Perform the desired per-protoco l mapping and definition assignments for each point, including the nam e, timeout and “[...]

30 13. Console Access 13.1 RS232 The console is accessible via an RS232 interface for direct connection to a computer’s serial (COM) port. This is performed by connecting the unit’s RS232 (MMI) port to the computer’s serial port via the included serial cable. 13.1.1 Requirements All that is needed is a computer wi th a serial (COM) port conta[...]

33 13.2 Invocation The console provides standard access and editing methods for the various configuration items (ports, points and their associated attr ibutes). It is important to note that whenever y ou modify the point database and are ready to restart the gateway (“exit”), you must save the dat abase to the internal file system prior to res[...]

34 13.3 Main Menu The main menu is shown in Figure 14. All gatew ay configuration is performed by “drilling dow n” into progressively low er-level menus. Figure 14: Console Main Menu All navigation and data entry commands are input by simply entering the menu selection number to the right of the “ > ” symbol along w ith any required data[...]

49 14. Pr otocol-Specif ic Informa tion This section will discuss topics that are s pecific to each of the available netw ork selections. 14.1 Modbus The gateway supports Modbus slave and ma ster functionality via Modbus RTU. The slave implementations share comm on access methods, which is to say they support the same functions and re ference the i[...]

50 • Because the transaction is handled loca lly w ithin the gateway , write data checking is not available. For example, if a w rite is performed to a register wi th a data value that is out-of-r ange of the corresponding “source port” object, no Modbus exception will be imm ediately returned. However, the point will alw ays reflect the “s[...]

51 For clarity, let’s use Equation 1 and Equati on 2 in a calculation example. Say, for instance, that we are going to r ead 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 det ermine that the bit within register #3 that coil #34 targets is (34[...]

52 • Note that various manufacturers w ill document their Modbus slave products in different w ays. In par ticular, according to the Modbus specification, registers have two diffe rent indices at which they can be referenced: their “known as” value (w hich starts at number 1) and their “addressed as” value (which is alw ays 1 less than th[...]

In other words, w hen a point in the [...]

54 14.3 Toshiba Common Serial ASD Protocol • The gateway can act as a Toshiba ASD master via its dedicated common serial (TTL) port connections. All T oshiba drives that include a common serial port are supported. • No configuration is necessary, as the gateway automatic ally adapts to the ASD’s configured characteristics. • The RS485 port [...]

55 that this may involve hardw are conf iguration in addition to parameter changes. For example, G7/Q7/H7-seri es drives have duplex selection jumpers located on the drive’s control board near the communication ports. For these drives, both jumpers must be placed in the “HALF” position. Refer to Figure 31 for an example det ailed view of corr[...]

56 • The RS485 port and the ASD1 port of t he gateway are internally shared, wh ich means that they both cannot be active simultaneously. Also, the RS485 port’s configuration has priority over that of the ASD1 port: if any protocol is assigned to the RS 485 port, then the ASD1 port w ill be automatically disabled. Note, how ev er, that the ASD2[...]

57 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, In c. M3000, M4000 and M5000-series drives that support the Mitsubishi proto[...]
