  • Page 7: Introduction

    Installation Flowchart INTRODUCTION WirelessHART technology overview The WirelessHART technology is based on a wireless mesh network communication protocol used in process automation applications. It adds wireless capabilities to the HART protocol, while maintaining compatibility with existing HART devices, commands and already known and used tools. WirelessHART network Basically, a WirelessHART network, defined in the HART specifications, consists of a host, a WirelessHART Gateway and one or more field devices and/or WirelessHART adapters.
  • Page 8 – Operation & Maintenance, Instruction Manual TT481 WirelessHART Network Manager The Network Manager is an application that can be embedded in the WirelessHART Gateway. On a WirelessHART network is only allowed to have one Network Manager. Among its responsibilities, the Network Manager distributes network identity (advertisement) publishing its existence, manages and authenticates the addition (joining) of devices to the network.
  • Page 9 TT400 WirelessHART - Manual de Instrução, Operação e Manutenção Planning an WirelessHART network The planning of a WirelessHART network is a task that is very similar to the activities that currently we perform with conventional wired devices. Furthermore, due to the simplicity of a mesh WirelessHART network, is exempt, in general, detailed field surveys, which are usually needed when we plan networks based on other wireless technologies.
  • Page 10 – Operation & Maintenance, Instruction Manual TT481 WirelessHART o Reposition the gateway as needed ; o Check the coverage area of each device; o Ensure that each device has three neighbors within its coverage area; o Place the repeaters as needed. Installation As mentioned before, WirelessHART devices should be connected to the process and configured the same way as conventional wired HART devices.

  • Page 21: Section 2 - Operation

    Section 2 OPERATION The TT481 WirelessHART accepts signals from mV generators such as thermocouples or resistive sensors such as RTDs. The criterium is that the signal is within the range of the input. For mV, the range is -50 to 500 mV and for resistance, 0 to 2000 Ohm. For current the range is 4 to 20 mA. Functional Description-Hardware Refer to the block diagram (Figure 2.1).
