Connection X4 - PROFIBUS DP (LES 36…/PB)
Note!
Connection X4
PROFIBUS DP
is assigned only on the LES 36/PB and LES 36HI/PB.
The connection to the PROFIBUS DP is made via the 5-pole X4 M12-socket with an external
Y plug adapter. Assignments correspond to the PROFIBUS standard. The Y plug adapter
enables the replacement of the LES 36…/PB without interrupting the PROFIBUS cable.
The external Y plug adapter is also needed if the LES 36…/PB is the last network device.
The external bus terminating resistor (termination) is then connected to this. The 5V-supply
for the termination is connected to X4.
Note!
For the connection, we recommend our ready-made PROFIBUS cables (see chapter 15.2.5
"Connection accessories / ready-made cables for X4 (only LES 36…/PB)")
For the bus termination, we recommend our PROFIBUS terminating resistor (see
chapter 15.2.5 "Connection accessories / ready-made cables for X4 (only LES 36…/PB)")
