][Funktionsbeschreibung XR

The module is a remote station used to extend the PSSu module bus via

a cable connection. The remote station is always the first module in a re-

mote system.

In the remote system, a supply voltage module with the relevant base

module must be used after the remote station:



For supply voltage modules with infeed for the periphery supply,

module supply and C-rail supply, a base module must be used to re-

fresh the supply voltage (PSSu BS-R...).



For supply voltage modules with infeed for the periphery supply and

C-rail supply, a base module must be used to provide the supply volt-

age (PSSu BS-R...).

][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

reaction 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.
