14.4.2 Terminal Resistor
When AHRTU-PFBS-5As are installed at the two ends of the PROFIBUS network, their PROFIBUS
interfaces need connect the terminal resistors including the following 3 resistors, Rt, Ru and Rd. The
standard PROFIBUS connector contains the built-in terminal resistor which user could select
whether to connect to the station or not via the switch. User could purchase the standard
PROFIBUS connector to add the terminal resistor.
