Loop-Through Connection Of Profibus Dp And Supply Voltage - Siemens ASM 456 Operating Instructions Manual

Connection

4.4 Loop-through connection of PROFIBUS DP and supply voltage

4.4 Loop-through connection of PROFIBUS DP and supply voltage
Properties
The terminal block has one connector for the supply and one socket for looping through the
supply voltage and PROFIBUS DP. The connector for supply and the socket for loop-through
connection are linked with one another internally.
Result: If you remove the terminal block during operation, other PROFIBUS nodes do not
fail.

NOTICE
Ensuring the degree of protection
The IP65, IP66 or IP67 degree of protection is no longer guaranteed if the terminal block is
removed.
