The module is a base station used to extend the PSSu module bus via a
cable connection. The base station is always the termination module in
a base system.
][Funktionsbeschreibung XB/XR
The cable connection disconnects the PSSu module bus on the base
station and continues it on the remote station.
All FS data, all ST data plus the module supply are transferred via the
cable connection. The periphery supply and C-rail supply are not trans-
ferred. Up to three PSSu systems can be connected, i.e. you can have
up to two successive cable connections.
The cable connection does not appear in the process image. The cable
connection does not need to be considered in the user program. The re-
action times of the modules on the remote system are not affected by
the cable connection.
The base system is terminated using a special terminating plate (PSSu
A EC XB, supplied with the remote module). The remote system is ter-
minated using the terminating plate supplied with the head module.
][Funktionsbeschreibung PD  The module routes the periphery supply from the module bus to the
base module terminals.
 The module does not switch the periphery supply.
 The periphery supply has no current limitation.
