INTERBUS

The descriptions for INTERBUS apply to all Inline controllers listed on the inner cover
page of this user manual.
Observe the information in the "Configuring and installing the INTERBUS Inline product
range" user manual IB IL SYS PRO UM E when creating an Inline system (local bus
and/or remote bus).
Please note that the Inline controller does not support the following functions:
– Switching of devices
– Single-channel diagnostics
– Fiber optic diagnostics/optical regulation
– Logical addressing
Only INTERBUS devices with SUPI 3 and SUPI 3 OPC protocol chip or later can be used
with INTERBUS as local bus/remote bus devices.
2.13.1

Local bus

The local bus is automatically created by directly connecting I/O modules to the Inline con-
troller.
2.13.2

Remote bus

Please note: the ILC 131 ETH and ILC 131 ETH/XC controllers do not support connection
of the INTERBUS remote bus.
Connect the remote bus to the Inline Controller using the IBS IL 24 RB-T-PAC branch termi-
nal (Order No. 2861441; including accessories).
The first branch terminal must always be placed directly after the Inline controller. In
terms of topology, it opens a remote bus.
If additional branch terminals are used after the first branch terminal, they must be in-
stalled directly one after the other (see also notes in the terminal-specific data sheet). In
terms of topology, the additional branches are remote bus branches with the branch ter-
minal being the first device in the corresponding remote bus branch.
A maximum of 3 branch terminals can be connected to the Inline controller, each of which
opens a remote bus (see Figure 2-3 on page 14).
