Note
A teleservice adapter can be connected to the PROFIBUS interface X21 for remote
diagnostics.
The power supply for the teleservic
e (terminals 2 and 7) can have a max. load of 150 mA.
For the first and last participants in a bus line, the terminating resistors must be switched in,
otherwise, data transmission will not function correctly.
The terminating resistors are activated in the connector.
The cable shield must be connected at both ends over large-surface area contacts.
