Figure 1 IBS IL 24 BK-T/U terminal with
connectors and end plate
Please note that the connectors are
not supplied as standard with the
terminal. To order these connectors,
please refer to the "Ordering Data" on
page 22.
The end plate is supplied with the bus terminal.
Place this plate at the end of the Inline station.
The end plate does not have any electrical
function. It protects the station from ESD pulses
and the user from dangerous voltage.

Do not mix up the connectors
Do not mix up the connectors, especially the remote bus connectors and connectors for
the voltage supply, as this may damage the terminal.
Observe the current carrying capacity
The maximum total current of the potential jumpers U
and US is 8 A.

Ground the bus terminal
Connect the bus terminal to functional earth ground (FE) via one of the FE connections of
connector 3 or connector 4. Connect the corresponding contact with a grounding terminal
block (see also Figure 6 on page 10).

Observe the current consumption of the modules
Observe the logic current consumption of each device when configuring an Inline station.
This information is given in every module-specific data sheet. The current consumption
can differ depending on the individual module. The permissible number of devices that
can be connected depends on the specific station structure.
Functions
Reconfiguration (external) If necessary, you can connect an external
reconfiguration button to the bus terminal (see
Figure 6 on page 10).
Pressing this button activates the reconfiguration
request to the controller board.
Interface configuration (internal) When the next device is snapped on, the bus
terminal configures the interface automatically.
If the next device is a terminal with remote bus
branch, the interface is configured as a remote
bus interface.
For every other device (e.g., I/O terminal) the
interface is configured as a local bus interface
with diagnostics.
