Bus Termination With Termination Resistors (Cpv−Di02); Installation Cpv−Di02 And Cpv−Cs02 - Festo CPV-D102 Elektronics Manual

1. Installation CPV−DI02 and CPV−CS02
1.4 Bus termination with termination resistors (CPV−DI02)
1−24
Note
If the valve terminal is at the beginning or the end of the
field bus system, a bus termination will be required.
Fit a bus termination to both ends of a bus segment.
·
Recommendation:
Use the ready−to−use field bus plugs from Festo for the bus
termination. A suitable resistor network is incorporated in the
housing of this plug (see Fig. 1/7).
