How to install the PROFIBUS DP terminating resistor
The first and the last node of a PROFIBUS DP segment must be terminated with a
wave impedance.
At the last bus node, plug the terminal resistor module onto the right–side
connector of the corresponding ECOFAST terminal block. For procedures please
refer to Connecting the ECOFAST connector. For order numbers please refer to
Appendix A.
Figure 3-8
Connecting the ECOFAST connector
Note
The terminating resistor is powered via the electronic/sensor power supply (1L+).
Trouble–free operation of the terminating resistor is only ensured if it is connected
to an electronic/sensor power supply (1L+) with a tolerance of range of
±
10%.
Closing unused sockets
Close all unused ECOFAST sockets with caps in order to achieve protection class
IP 65, IP 66 or IP 67. For order numbers please refer to Appendix A.
