About mobiLink
mobiLink is a mobile communication device designed to configure and manage field devices
(HART, FOUNDATION fieldbus or PROFIBUS PA) in hazardous and non-hazardous areas from
PCs, tablet computers or smartphones by wired or wireless communication. Operation of
this communication device requires the use of suitable management tools like FDT frame
applications or configuration tools on Windows PCs or tablets or smartphones.
2.1Intended use
mobiLink is used to interface with network segments to configure, commission and maintain
connected field devices (HART, FOUNDATION Fieldbus or PROFIBUS PA fieldbus). mobiLink may
be used both in field installations and in bench applications. As mobiLink does not supply
power to the connected devices, a powered HART loop or powered fieldbus segment is
required when using mobiLink in bench applications.
mobiLink is certified for hazardous areas and can be connected to intrinsically safe field
devices. See the section Functional Description for details.

Product overview
mobiLink combines a HART modem and a Manchester encoded bus-powered (MBP) fieldbus
interface in a single portable device. It features a full-blown HART master, a FOUNDATION
Fieldbus host and a PROFIBUS PA master and therefore supports all three major
communication protocols used with process field devices.
Host devices, tools and applications
mobiLink provides access to field devices from FDT frame applications and configuration
tools running on host devices (PCs, tablets or smartphones) connected via USB or Bluetooth.
If you connect mobiLink to a host device on the USB port, the mobiLink automatically starts
USB communication. Conversely, if you switch on mobiLink without a wired USB connection,the device automatically activates wireless Bluetooth communication. It is not possible to
use Bluetooth while the USB cable is connected. If the USB cable is disconnected during
operation, mobiLink is powered off. Connecting the USB cable during Bluetooth operation
will cause mobiLink to reboot.
Power supply and consumption
mobiLink uses three AA batteries. The battery lifetime depends on the mode of operation.
Using Bluetooth communication, one set of batteries can last several working days. USB
mode increases battery life time, but cannot be used in hazardous areas. mobiLink does not
supply power to connected field devices. A powered HART loop or powered fieldbus
segment is required. When connected to a fieldbus segment, the mobiLink fieldbus interface
draws 10 mA from the fieldbus as required by the specification. To improve the battery
lifetime of mobiLink in bench host applications, the host application may set the power
drawn from the fieldbus to 18 mA in USB mode.

Chapter 3 - Product overview
HART or fieldbus communication
mobiLink can operate as HART modem, FOUNDATION Fieldbus or PROFIBUS PA fieldbus
interface. The two different electrical interfaces for HART and fieldbus operation share a
common socket. The mode of operation is selected by the host application. mobiLink checks
whether the electrical conditions on the interface match the selected mode. mobiLink must
therefore be connected to a HART device or fieldbus segment before the host application is
started. An LED marking the HART or Fieldbus socket indicates in which communication
mode mobiLink is running.
