12.3.3 Supply when connecting sensors and actuators in 1-wire

technology

If you are not supplying 1-wire technology sensors and actuators using the IB IL 24V-

PAC or IB IL GND-PAC potential distributor terminals, these terminals must also be sup-

plied from the power supply unit that was used to supply U

12.3.4 Testing the supply during startup

During startup, make sure that all GND connections of the supply connectors of an Inline

station are connected to GND (0 V) of the relevant power supply unit by means of mea-

surement. For this purpose, remove all power connectors from the relevant terminals and

measure the connection.

When using power terminals, make sure that they are assigned to the correct power sup-

ply unit in order not to decrease electrical isolation within the station.

12.3.5 Behavior during reset at the bus coupler, Inline controller or

field multiplexer

NOTE: Malfunction

If you want to perform a reset at the head of the Inline station by switching the sup-

ply voltage off and on again, disconnect power to all I/O devices connected.

Disregarding this measure may lead to unwanted feedback.
