Communication between the display unit and connected equipment is
achieved by means of a communication protocol, which is selected when
creating the application in XBT L100•.
The protocols available for the range support communication with the
Schneider range of PLCs, specific equipment (speed drives), etc.
These protocols are Uni-Telway and Modbus (master and slave).
There are several types of architecture, which enable one display unit to
be linked to several devices or several display units to one device.
 Point-to-point connection
One display unit linked to one device.
