Connecting the PROFIBUS
The 9-pin D-Sub socket is used for connection.
– Only use standard PROFIBUS plugs and cables.
– Wire the PROFIBUS plug according to the details for pin
assignment (see "Technical data" on page 34).
– If the TH LINK is installed at the beginning or end of the
PROFIBUS cable segment, you will need a bus terminating
resistor (see "Bus terminating resistors" on page 30).
1. Attach the PROFIBUS connector onto the PROFIBUS
socket on the TH LINK.
2. Secure the plug with screws.
3. Switch the switch for the bus terminating resistor on the
PROFIBUS connector to the required position (ON/OFF).
Warning!
Do not use branch lines for the connection.
If local conditions do not allow a direct
connection, use a repeater (connection
according to PROFIBUS norm).
