Terminating resistor (cable termination)
Bus segments must be concluded at both ends with a
terminating resistor. This also applies if the module or
communication processor is at the end of the bus
cable.
Recommendation: Use plugs with an integrated termi-
nating resistor if you are connecting the SPC200 at the
end of a bus segment. If necessary, switch in the termi-
nating resistor.
The diagram below shows the circuitry of the terminat-
ing resistor combination of cable A as per EN 50 170.
