1.3.5 Bus termination with terminating resistors
Please note
If the CPX terminal is at the beginning or end of the field
bus system, a bus termination is required.
·
Use a bus termination at both ends of a bus segment.
A resistor between Data A and Data B is used as a bus
termination (depending on cable type, see table).
