NOTICE
Ensuring the degree of protection
Cover all unused push-pull sockets with caps in order to ensure degree of protection IP65,
IP66, or IP67. For order numbers, refer to the section "Ordering data (Page 63)".
4.3 Loop-through connection of PROFINET IO and supply voltage
Features
The connection block features one connector for the incoming supply and one socket for
loop-through connection of the supply voltage. The connector and the socket for the supply
are linked with one another internally.
Two sockets are available for the incoming PROFINET IO and for loop-through connection.
The sockets are not connected to each other in the connection block. The switch in the base
unit creates the logical connection.
Note
If you disassemble the connection block during operation, only the power supply will be
looped through. Data communication to subsequent devices will be interrupted from this
module onwards.
