    INTRODUCTION 1.1 Overview The Wireless Gateway products provide a wireless interface between various fieldbus protocols used in process and automation applications. The WI-GTWY-9-xxx includes an integral 900MHz license-free radio transceiver, and WI-I/O 9 transfers transducer and control signals (I/O) using a highly secure and highly reliable radio protocol.

  • Page 10: Modbus / Df1 Wi-Gtwy-9-Md1

    The WI-GTWY-9-MD1 has two serial connections - RS232 and RS485, on the bottom end plate of the module. The serial port provides both RS232 and RS485 hardware connections, however both connections are paralleled internally - both connections cannot be used at the same time.

  • Page 12: Ethernet Wi-Gtwy-9-Et1

    8 discrete inputs or outputs, but analog or pulse I/O take up 1 byte for low resolution values (8-bit) or 2 bytes for high resolution values (16-bit). An “output” is a value coming into the WI-GTWY-9-ET1 via the fieldbus. An input is a value going out from the WI-GTWY-9-ET1 via the fieldbus.

  • Page 13: Modbus Plus Wi-Gtwy-9-M+1

    Each register can be 16 discrete inputs or outputs, or one analog or counter 16-bit value. An “output” is a value coming into the WI-GTWY-9-M+1 via the fieldbus. An input is a value going out from the WI-GTWY-9-M+1 via the fieldbus.

  • Page 14: On-Board I/O

    1.2.1 On-board I/O The WI-GTWY-9-xxx has eight on-board discrete I/O. Each I/O point can be used as either a discrete input (voltage free contact input) or discrete output (transistor output) - an I/O point cannot be used as both input and output.

  • Page 15: The Wireless Network

    Any WI-GTWY-9-xxx or WI-I/O 9-x module can act as a radio repeater for other modules - that is, radio messages can be passed onto other modules. Up to five repeater addresses can be configured for messages transmitted to a WI-GTWY-9-xxx module.

  • Page 17 WI-GTWY-9-xxx “sees” a large number of changes in its database at the one time. For example, if a host writes a block of 100 signal values to a WI-GTWY-9-xxx, and 20 of these values have changed since the last write-operation. If the block is mapped to another WI- GTWY-9-xxx, then the WI-GTWY-9-xxx can transmit all 20 values in one radio message, instead of 20 messages.

  • Page 18: Wi-Gtwy-9-Xxx Repeaters

    1.3.4 WI-GTWY-9-xxx Repeaters Any WI-I/O 9-x module can repeat a normal radio message, however only WI-GTWY-9-xxx modules can repeat a block message. WI-GTWY-9-xxx units connected to a host device can also act as a repeater for other modules. Where a WI-GTWY-9-xxx is being used without a host device as a repeater or data-concentrator, it can be configured as “Repeater-only”.

  • Page 19: Chapter 2 Operation

    For the host device, the WI-GTWY-9-xxx provides an "Active" signal on the RS232 port (DCD pin 1). Its purpose is to indicate to the host that the WI-GTWY-9-xxx is now processing output messages for the remote modules. When the WI-GTWY-9-xxx powers down (or should an internal fault occur), the "Active"...
  • Page 20 WI-GTWY-9-xxx will convert the 16 bit value into a binary (1 bit) value before it responds. The WI-GTWY-9-xxx is able to scale the I/O value between the I/O database and the host device - this is a user-configurable function.
  • Page 21 WI-GTWY-9-xxx Wireless Gateway V1.18 again when the WI-GTWY-9-xxx receives a message from the remote module. The default configuration is that output updates ARE sent during comms fail conditions.

  • Page 22: D Atabase

    Whenever an output register is set “on”, the corresponding input register is automatically set “off”. For example, if register 4321 is set to “1”, the WI-GTWY-9-xxx will also set 4301 to “0”. This means that if both the input and output registers corresponding to the same I/O point are used in the configuration, then the output register has priority.
  • Page 23 WI-GTWY-9-xxx Wireless Gateway V1.18 The WI-GTWY-9-xxx also monitors its battery voltage and supply voltage. These are stored in registers 4310 and 4311 respectively, as 16 bit values, scaled so that a value of 16384 decimal (hex 4000) corresponds to 8 V, and a value of 49152 (hex C000) corresponds to 40V.

  • Page 24: The Host - Wi-Gtwy-9-Xxx Link

    8 discrete (binary) values, or two bytes can be used for a 16-bit analogue or pulse register. So the interface is limited to 4300 discrete inputs (the limit of the WI-GTWY-9- xxx database) or 1024 analogue inputs (the limit of the HMS interface) or a combination. The same applies for outputs.

  • Page 25: Radio Signal Strength

    4425. The WI-GTWY-9-xxx will not know what the radio strength of the message from #24 to #25 is. If #25 is another WI-GTWY-9-xxx, then it can record this RSSI and this register could be mapped to an I/O register in the first WI-GTWY-9-xxx.

  • Page 26: Repeaters

    The communications failure status is bit 15 of the status register for each I/O point. If the host device reads a register as a digital or binary value, then the WI-GTWY-9-xxx returns bit 15 of the register (0 or 1) - this is the comms fail bit of a status register.

    V1.18 For information on antennas and cables for the WI-GTWY-1 licensed products, please refer to Weidmuller, Inc. or an authorized distributor. Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses.

  • Page 32: Power Supply

    3.3 Power Supply The WI-GTWY-9-xxx power supply is a switch-mode design which will accept either AC or DC supply. The module includes an integral battery charger for a backup battery.

    V1.18 4.3.1 Loading from a WI-GTWY-9-xxx If you load a configuration from a WI-GTWY-9-xxx into a “blank” or new project, then the program will not be able to display the mappings from remote modules (as the program does not know what the remote modules are). You will get a warning message like this:...

  • Page 51: Mappings Wi-Gtwy-9-Xxx To Wi-I/O 9-X I/O Modules

    Refer to the WI-I/O 9-x I/O User Manual. When mapping inputs to a WI-GTWY-9-xxx, you will be asked to select an I/O Register. Select the “…” box beside the “At I/O Register” heading - this will allow you to select the I/O register between 0 and 4299.

    To set the comms fail times, select the WI-GTWY-9-xxx, and select the “Comms Fail Time” option. Each remote input already mapped to the WI-GTWY-9-xxx will automatically be listed, including the remote module containing the mapping.
  • Page 53 WI-GTWY-9-xxx Wireless Gateway V1.18 Change Sensitivities Radio messages to remote modules can be change messages (when the value of the I/O register changes) or update messages (when the update time has elapsed). If a change message is sent, the update period restarts.

  • Page 54: Don't Send If In Comm Fail

    You can configure a special “Don’t Send if in Comms Fail” mapping. If this is configured for a particular remote module, the WI-GTWY-9-xxx will not transmit output messages to this remote address, if there is a communications failure status on any input or output configured for the same remote address.

  • Page 57 WI-GTWY-9-xxx. In the above example, the destination block will be I/O registers 32 – 46 (15 registers starting at register 32). So, in the above example, a block of 15 x 16-bit values will be written from I/O Reg 110 – 124 in WI-GTWY-9-xxx#1 to I/O Reg 32 – 46 in WI-GTWY-9- xxx#2.

  • Page 58: Host Device Trigger

    A block mapping can be “triggered” or initiated by several different methods. • By the host device writing to a “trigger register” in the source WI-GTWY-9-xxx - the block mapping message is sent each time the host device writes to the trigger register.

  • Page 59: Time Period

    WI-GTWY-9-xxx Wireless Gateway V1.18 Each block mapping that is configured is allocated a status register in the range 9500 – 9999 (i.e. one status register for a maximum of 500 possible block mappings). The status register for a given block mapping is shown on the right hand side of the Block Mapping display (under the heading “Status Lcn”).

  • Page 60: Real-Time

    The reason for the offset is to stagger messages with the same time setting. For example, if you configure 5 block mappings all to be sent at 10 minutes, then the WI-GTWY-9-xxx will try to send these messages at the same time - some of the messages will have to wait until the earlier messages have been sent.
  • Page 61 V1.18 Setting the Clock The clock within the WI-GTWY-9-xxx can be set by the host device, and read by the host device. The WI-GTWY-9-xxx provides four clock registers for days/hours/minutes/seconds - the registers are 4330 – 4333. On power-up, these registers are set to zero. Reg 4333 increments each second, Reg 4332 increments each minute, Reg 4331 each hour and Reg 4330 each day.

  • Page 63: Mixing Normal Mappings And Block Mappings

    WI-GTWY-9#1 will send a block mapping request to WI-GTWY-9#2 who will then send a block mapping from its I/O registers 52 for a count of 10 to WI-GTWY-9#2 I/O registers 52 – 61. This Block read will be performed using the real time clock at 10-minute intervals. A response timeout of 5 seconds is used to indicate that if the Block read values have not been received in 5 seconds then the Comms Fail bit for this block read mapping will be set.

  • Page 64: Comms Fail For Block Mappings

    - this can be monitored by the host device. 4.5.10 “Repeater-only” Configuration Any WI-GTWY-9-xxx module can act as a repeater unit. However a WI-GTWY-9-xxx may need to be installed as a repeater only (that is, there is no host device connected). In this case, the base WI-GTWY-9-xxx, the WI-GTWY-9-xxx-MD1 unit would normally be used as this is the lowest cost of the WI-GTWY-9-xxx modules.

  • Page 65: Change Sensitivity & I/O Value Scaling

    WI-GTWY-9-xxx Wireless Gateway V1.18 4.6 Change Sensitivity & I/O Value Scaling 4.6.1 Change Sensitivity “Change” messages for both individual I/O mappings and block mappings use a sensitivity value to trigger the message. Sensitivities are configured for blocks of I/O registers - that is, each I/O register does not have a unique sensitivity.

  • Page 66: I/O Value Scaling

    A sensitivity value of 1 in 65535 is a change of 0.0015%. If the host device writes an analogue value to a WI-GTWY-9-xxx every 100msec, it will change by at least 1 bit each time. A small sensitivity value will cause a change message to be sent every 100msec. If there are many analogue values in the same situation, then there would be many change messages every 100msec.
  • Page 67 WI-GTWY-9-xxx Wireless Gateway V1.18 Scaling is configured in the “Sensitivities” section of the configuration software. If you select a new sensitivity/scaling block, you can select/deselect sensitivity or scaling or both. There is no relationship between sensitivity and scaling - we use the same configuration area as it is convenient because both features use blocks of I/O registers.
  • Page 68 WI-GTWY-9-xxx Wireless Gateway V1.18 The second example shows another I/O block (registers 81 to 1080) that has been selected for scaling only - the sensitivity function has been disabled (these registers will use the default sensitivity of 2000 configured on the main Sensitivity configuration screen).
