1.6.1 Information concerning the switch-on behaviour of the bus node

1-18
In order to avoid connecting and addressing errors, you
should carry out commissioning in steps as follows. Observe
the following information concerning the switch-on beha-
viour:
Please note that any devices to be connected must be
•
logically connected to the bus node before switching on
the CTEU bus node, otherwise it will result in an error
message and no process data will be available for trans-
mission.
Only mount the bus node to the same or an identical and
•
equally-configured device while maintaining the operating
voltage supply in order to avoid any malfunctions.
The configuration of connected devices is lost as soon as
the operating voltage supply of the bus node is discon-
nected.
Disconnect the operating voltage from the bus node be-
•
fore connecting other devices, as the configuration pro-
cess is only retransmitted after the bus node is switched
on again.
Before switching it on, make sure the details regarding
•
the fieldbus configuration are complete and correct.
Connect any devices to the bus node via the I-Port, as
•
these are only recognised by the bus node when the oper-
ating voltage is switched on.
