LB Remote I/O System
Installation
Pinning on Sub-D Plugs
Pin 1 Optional shield
Pin 2 -
Pin 3 (B) RxD/TxD-P (+) receive/send data P
Pin 4 Optional control signal P
Pin 5 GND reference potential
Pin 6 + 5 V, only at the end of the line
Pin 7 -
Pin 8 (A) RxD/TxD-N (-) receive/send data N
Pin 9 Optional control signal N
When installing, make sure that the transmitting and receiving lines at pin 3 and pin 8 have not
been swapped. If the lines have been swapped, the remote I/O station cannot be reached via
the fieldbus. If the lines were swapped when looping through, all nodes after this point cannot
be reached via the fieldbus.
X40 Terminal Assignment
Auxiliary energy for 4-channel digital outputs LB6*10* ... LB6*15* can be connected via the
booster connection.
X40.1 = 0 V

X40.2 = + 24 VDC (SELV/PELV)

X40.3 = earth

S1 Switch Positions and X3 Terminal Assignment
The S1 switch and X3 terminal control the bus-independent deactivation of the I/O modules.
The terminator on the X4 fieldbus connection can also be activated and deactivated using the
S1 switch.
S1.4
ON
OFF
The bus-independent deactivation of the I/O modules only works for I/O modules equipped
with a shutdown input. I/O modules with and without a shutdown input can be installed on the
same backplane; however, only the I/O modules that are equipped with a shutdown input are
controlled by the bus-independent deactivation.
If I/O modules equipped with a shutdown input are installed on the backplane, these modules
can be deactivated using an external switch, for example.
