VEGA Remote parameter adjustment and remote maintenance - Manual (Page 4)

Information:
With most PLC systems and other universal power supply units, this
resistance must be used for communication. VEGAMET 381 (Ex),
VEGADIS
371 (Ex), VEGATRENN 149 Ex are constructed in such a
way that no additional resistance is required. With VEGAMET 624/625
and VEGASCAN 693, no communication is possible via the HART
cable. Here, communication to the sensor is carried out via one of the
integrated interfaces of the signal conditioning instrument.
