Profibus
The transmitter has a modular design with discrete, replaceable electronic modules and connection boards
to maintain separation between functions and facilitate field service. All modules are fully traceable and
their provenance is included in the transmitter setup.
The bus termination can be activated via a switch internal in the transmitter. The bus termination switch is
set to off by default. If the internal switch is not used for termination an external separate bus terminator
must be installed. The internal switch is located on the transmitter PCBA module.
